Commercial Spaceflight Comes to the Fore at Toronto Congress

The 65th International Astronautical Congress, the third to take place on Canadian soil, will likely be remembered for marking the coming-of-age of commercial provision of human spaceflight. Sessions devoted to that topic at last week's congress at the Toronto Convention Centre were standing room only affairs in big rooms, unlike previous congresses, where commercial human spaceflight sessions took place in small and unfilled rooms.

The rise of commercial human spaceflight shows that the space policy of the Barack Obama administration is taking hold, especially with September's announcement that Boeing and SpaceX had been contracted to supply astronaut ferry services to the International Space Station, hopefully starting in 2017. Since the space shuttle flew its last mission in 2011, U.S. astronauts have been dependent on Russian Soyuz spacecraft to get to the station. 

Boeing and SpaceX had major presences in the trade show at the Toronto IAC, as did Sierra Nevada, which  after the NASA decision against it is looking for other customers to buy into its Dream Chaser space plane concept. Sierra Nevada has also resorted to asking the courts to overturn NASA's decision to choose its competitors.

NASA officials explaining the turn to commercial provision of spaceflight services compared these spacecraft to trucks. When the U.S. government needs trucks today, it buys vehicles designed and built by private industry rather than designing its own trucks and having them built to those specifications. That policy is already in operation with SpaceX Dragon spacecraft and Orbital Sciences Cygnus spacecraft delivering supplies to the ISS.

NASA Associate Administrator  Bill Gerstenmaier told one session that NASA's current vision means far greater change than simply what spacecraft are used to carry crews to the ISS. Once the station is retired, perhaps as soon as ten years from now, radical changes could be in store for spaceflight in low Earth orbit (LEO).

Gerstenmaier said LEO should become the place where the private sector uses the space environment to improve life on Earth, providing services such as remote sensing of Earth and using the space environment to develop new materials.

If he were handed the money to build another ISS, Gerstenmaier said he wouldn't take it. "If you give your money to me, I'll take it and go explore." The targets of NASA's  exploration plans include the planet Mars, asteroids, the Moon, and other bodies in the solar system.

Much of that exploration will likely be done with the Orion spacecraft being built  for NASA by Lockheed Martin. Orion got its start under the Bush space policy a decade ago, and the first test launch of Orion is slated for December.

Other commercial providers of spaceflight were also present at the congress. Virgin Galactic, whose plans to carry paying passengers on suborbital flights have been repeatedly postponed, updated delegates on their problems with propellant for their SpaceShipTwo vehicle and hopes to begin full operations next year. Tickets are available for $250,000 a ride. Far more expensive are commercial trips around the Moon being offered on Russian spacecraft by Space Adventures Ltd. at $180 million. 

Canada Plays Politics

A tradition at these congresses is for the heads of the world's major space agencies to gather. The leaders of the Russian and Chinese space programs were conspicuous by their absence from Toronto, and the reason turned out to be the Harper government 's decision to refuse them visas. 

In the case of Russia, many countries have sanctioned the Putin government for its illegal takeover of the Crimea and complicity in the destruction of a Malaysian Airlines aircraft, but Canada seems to be the only country extending these sanctions to space activities. Earlier this year, Canada had pulled a Canadian navigation satellite off a Russian rocket and at the congress it announced that the satellite would instead be launched by India.

Russia didn't have a booth at the IAC 2014 trade show, but Ukraine did.

Many delegates believe that the denial of visas to Russian space program officials, including well-known cosmonaut Sergei Krikalev, constituted a victory of the Harper government's domestic political imperatives over Canada's international reputation. Most space programs today, especially Canada's, rely on international cooperation, and the Canadian government's handling of these visas could have unexpected repercussions.

Canada's space program, including the Canadian Space Agency's remaining astronauts, David Saint-Jacques and Jeremy Hansen, were front and centre at the congress, but with budgetary restraint being the order of the day at the CSA, there was little new on show except for Canadian contractor MDA's plans for a next-generation Canadarm for use on Orion and other spacecraft, new Earth-facing cameras slated for installation on the ISS by Vancouver high definition image provider Urthecast, and Toronto Italian espresso maker Lavazza's unveiling of a prototype espresso maker for the ISS.

While these products portend only minor changes, the rise of commercial human spaceflight means big changes in the field of spaceflight. With NASA leading the way by supporting commercial space providers, other space agencies, corporations and individuals may find it easier to book seats into Earth orbit.

In place of the Soyuz ferries and the ISS of today, tomorrow's space traveller may be able to choose between a number of commercial providers to get into orbit, where they will be able to visit space stations built by private providers, such as Bigelow Aerospace and its inflatable modules. And NASA astronauts, perhaps accompanied by Canadian astronauts and others, may fly beyond Low Earth Orbit to new destinations in the solar system. That's the vision spelled out at the Toronto congress, but events on Earth will ultimately tell whether this vision becomes reality.

The two most famous attendees at the congress were former Canadian astronaut Chris Hadfield, and Bill Nye the Science Guy, who is doing a great job as the new face of the Planetary Society. I bumped into Nye on the first day of the congress. 

Looking Back at Canada's Last International Astronautical Congress

Next week I will be in Toronto for the 65th International Astronautical Congress, the world's biggest annual meeting of people involved in the exploitation and exploration of space.

This annual event first took place in Paris in 1950, and it has rotated around the world since then, taking place last year in Beijing and scheduled for next year in Jerusalem. The meeting at the Metro Convention Centre, which goes from September 29 to October 3, is the third to take place in Canada - the IAC also took place in Montreal in 1991 and in Vancouver in 2004.

These meetings draw thousands of delegates, including astronauts, leaders of space agencies, managers, engineers, scientists, business people, lawyers, and even historians like me.

I took part in the Vancouver IAC ten years ago, and as the Toronto IAC approaches, I am reflecting on what has changed and not changed in space in the decade that has passed since the Vancouver meeting.

That meeting opened on October 4, 2004, which was not only the 47th anniversary of the launch of Sputnik but an historic day for space in its own right. That day SpaceShipOne completed the set of flights to the edge of space that won it the $10 million Ansari X Prize, heralding a new era of private space flight. That news created expectations that the day when tourists would be able to fly on short suborbital flights to the fringes of space was only a couple of years off.

A decade later, Virgin Galactic's SpaceShipTwo is still undergoing test flights and except for the handful of multi-millionaires who have been able to afford scarce seats on Soyuz spacecraft flying to International Space Station, the dream of space tourism remains on hold. No doubt this prolonged delay would have surprised those hopeful attendees at the Vancouver IAC in 2004.

Although Virgin Galactic's work to establish suborbital space tourism has moved at a slower and more deliberate pace than had been expected, it has met no serious setbacks, and there are hopes that the first flight with tourists on board will happen in the next year or two.

Other private space efforts have moved ahead in the past decade, usually with the help of governments.

At IAC 2004, I picked up a t-shirt and cap promoting a then-new firm called SpaceX, which has since created the Falcon 9 rocket that has established itself as a new force in the space launch field, and the Dragon spacecraft that is already carrying supplies to the ISS. Although a recent SpaceX experimental launch failed, the fifth Dragon delivery mission to the ISS arrived at the station this week, and SpaceX won the go-ahead last week from NASA to build a spacecraft to ferry astronauts to the ISS. The firm has prospered to a large degree because of the Barack Obama administration's policy of supporting private space launch providers.

The success of SpaceX relates to another event from 2004 - the George W. Bush administration's decisions to end the Space Shuttle program, which duly happened in 2011, and replace the shuttle with a new booster and spacecraft. The Bush administration's replacement program still exists as the Space Launch System and the Orion spacecraft, which are still years away from operational flight. These vehicles are competing with new rockets and spacecraft being created by SpaceX and other private sector providers supported by the Obama policy.

China's first astronaut, Yang Liwei (right), appears but doesn't speak at the Vancouver IAC.

Another big event at IAC 2004 related to China's space program. Late one day, word arrived that the next morning China's first astronaut, Yang Liwei, would make his first North American appearance at the IAC. Less than a year earlier, Yang had rocketed into space aboard the Shenzhou 5 spacecraft, serving notice that China was a rising space power.

Even though most of the astronauts who attended the IAC attracted little notice, Yang's appearance caused near pandemonium. In spite of the short notice, one of the larger rooms in the Vancouver Convention Centre was packed at the announced time of Yang's appearance, and he got a standing ovation from the large crowd as soon as he arrived.

Yang never spoke during the presentation about his flight, leaving all the talking to an official of the Chinese space agency. Cameras flashed throughout his appearance.

I was scheduled to give a paper at the same time, but everyone, including me, wanted to see the world's newest space hero. So we adjourned our history session and I gave my paper later that morning once Yang had gone.

Since then, China's human space program has moved at a deliberate pace. Four Shenzhou spacecraft with larger crews on board have followed Yang into orbit, the last two docking with China's first space station, Tiangong-1. China has also sent spacecraft to the Moon, most recently a robot that soft landed and then deployed a rover.

But more controversially, China has also developed military capabilities in space, notably an anti-satellite weapon that was used destroy a satellite in 2007, creating a serious and ongoing space debris problem. Tense relations between China and the United States caused NASA to reduce its presence at last year's IAC in Beijing.

Another 2004 event that reverberated at the Vancouver congress was NASA's successful landing of the Spirit and Opportunity rovers on Mars, signifying the resuscitation of NASA's Mars exploration program. Today Opportunity is still roaming the red planet, along with the larger Curiosity rover that landed two years ago. The Toronto congress takes place a few days after NASA's MAVEN spacecraft and India's Mars Orbital Mission were successfully inserted into orbit around Mars. The latter event has served notice that India has joined the ranks of the world's great space powers.

As the world's space industry heads to the Toronto congress, all these issues from ten years ago are still active. 

As well, the Toronto meeting will take place under the shadow of the ongoing tensions arising out of Russia's attacks on Ukraine that have pitted Russia against the United States and other space powers, including Canada.  Aside from some verbal threats, these tensions haven't yet affected the operations of the ISS.

Like other spheres of economic activity, the space industry is emerging from the protracted economic troubles that got under way in 2008. Activity in space by private firms and government agencies took hits from the recession, and next week we will see how far the space industry has bounced back.

Thoughts on the History of Technology

What do historians of technology do? Many people may think that we simply track the parts that go into the machines that we use in our lives and the systems that make modern life what it is. Or that we look at the individuals who are associated with various technologies, such as Thomas Edison or Bill Gates.

These topics are but a small part of our studies. The interaction of society and technology is a complicated one, and by studying this interaction we can learn a great deal about how technology and society evolve.

In explaining why we study the evolution of technology, I often start off with seemingly simple questions: are the technologies we use determined by the physical qualities of the devices involved? Or do people determine how these devices develop and are used?

An example I like to use when dealing with this question concerns stairs. When I display a photo of stairs being confronted by a person in a wheelchair, no one needs to be told what the person in the wheelchair is thinking. The person is wondering why there are only stairs and not a way of moving up or down that accommodates their disability.

Once buildings were equipped only with stairs, but today more buildings include other options such as ramps to help people get up and down regardless of their abilities. To put only stairs in a building was a conscious decision made by people, not something dictated by physics. And the fact that today buildings are routinely created to be accessible to all is a result of social change resulting from persons with disabilities and others advocating for this change.

Historians of technology look at questions like this, and at the design and use of things like the automobile. Why do our cars have certain capabilities and not others? Why and how did the internal combustion engine become the primary power source? Why not steam engines or the electric car? It's much more complicated than the superiority of one type of engine over another. It involved people making certain choices and sometimes acting to close off other choices for a variety of reasons.

In the matter of space exploration, we look at why it has progressed in the way it did. Why have humans gone to the Moon already? And why has no one gone back for more than four decades?

The history of technology is a relatively new discipline. Some date it to 1958, when the Society for the History of Technology (SHOT) was formed, although it certainly goes back farther as part of the older discipline of the history of science.

Thomas P. Hughes 1923-2014

Earlier this year, we lost one of the great historians of technology and one whose writings influence my own work, Thomas Parke Hughes, who passed away in Virginia at the age of 90.

Hughes is probably best known for his 1983 book, Networks of Power: Electrification in Western Society, 1880-1930, which compares how electrical power systems were set up in those years in Britain, Germany and the United States. While on the face of it, this is a dry subject, Hughes' account contained many insights about technology and the societies he covered in that book.

For example, early British power systems were private, small and highly decentralized. During this time, Britons moving just a few blocks would have to deal with a different power system and a different power provider with their own voltages and plug designs. Perhaps it was just as well that they had far fewer appliances back then! Germany had more centralized power systems that moved easily from private to state control, and the U.S. has been served by large private providers who fought ferociously against public power. The Great War that started 100 years ago led to greater centralization of power systems in all these places.

In that book, Hughes introduced ideas about phases in the development of technological systems, starting with invention and development, then technology transfer to and from other systems, followed by system growth and technological momentum as more people become dependent on a particular system. He also raised the idea of the technological reverse salient, where a system component does not progress along with other parts of the system in question, affecting the evolution of the whole system.

In American Genesis: A Century of Innovation and Technological Enthusiasm in 1988, Hughes wrote about how American culture was shaped by technological change and widespread popular enthusiasm for new technologies.

Two more recent works returned to technological systems. Rescuing Prometheus (1998) looked at the rise of systems engineering in the world of Cold War missile systems with the SAGE computer system and the Atlas missile, an area where I have done much of my historical work, and then its fall in large infrastructure projects in American cities, followed by its subsequent return in computer systems leading to the internet.

In Human Built World in 2004, Hughes discussed the interfaces between society and technology, arguing for a seamless web between the human and technological realms.

Hughes did not believe in technological determination and neither do I. But that doesn't mean that there isn't a complex interplay between technological systems and the societies they live in, with technologies affecting and being affected by political, social, and economic factors as well as their own physical properties.

Historians of technology such as Thomas Hughes have given us many insights about how technology affects our lives, and how society and social forces have shaped the technologies that we increasingly depend upon in our lives. These insights help us anticipate what the technological changes of today and tomorrow may bring.

A Great Summer at the Centre of the Universe

RASC volunteers and telescopes at the DAO on September 6. Chris Gainor photo.

The first summer of public outreach at the Dominion Astrophysical Observatory since last year's closure of the Centre of the Universe educational centre has gone in the books as a major success.

Large crowds came out for Saturday night public observing at the DAO, and space camps held for young students were also well supported. Having said that, this year's public outreach was not trouble free, and a lot of work needs to be done in the coming months to ensure that public outreach continues on a more permanent basis.

Last summer, the National Research Council of Canada, which runs the DAO, announced that the Centre and its public outreach work would close, although the DAO's research work would continue as it has for nearly 100 years. The Centre closed at the end of that summer.

By then, the public in Greater Victoria had shown its concern about the NRC's action by signing petitions supporting the Centre, and large crowds came out for the Centre's final public events.

In November, a meeting facilitated by Saanich South MLA Lana Popham brought people from the community and concerned groups together to begin the job of reconstituting public outreach at the DAO. The effort won support from the NRC, and for 2014, the Victoria Centre of the Royal Astronomical Society of Canada agreed to hold public observing nights at the DAO similar to what it had done before the Centre opened in 2001. 

The University of Victoria's Science Venture program agreed to hold space camps for children in Grades 3 to 8 at the Centre of the Universe building this summer. Science Venture is reported to be happy with the response to their space camps.

This year's public observing at the DAO began on May 3, Astronomy Day. Unfortunately, the weather didn't cooperate, but more than 200 people came to the DAO anyway to tour the historic Plaskett Telescope. The story was similar when summer Saturday observing sessions resumed on July 5. After that, the weather was nearly perfect for most of the next six public observing sessions over the summer, with crowds usually exceeding 400 people for each session.

Last Saturday, so many people turned up that traffic jams formed on West Saanich Road, and many people were turned back. Capacity for both people and cars at the observatory is limited, and this is a problem that will have to be addressed for next year.

For each public observing night, RASC volunteers showed visitors planets, stars and other celestial objects through their own telescopes, while other volunteers conducted tours of the Plaskett Telescope, which in four years will celebrate the 100th anniversary of its opening. I helped out inside the Plaskett and had the privilege of working alongside telescope operator Dave Balam, who is one of the world's top experts on asteroids.

Visitors to the first observing night in August got to meet CBC Quirks and Quarks host Bob McDonald, who received a certificate from Balam stating that an asteroid has been named after him.  Lana Popham and her friends arranged for popcorn and hot chocolate for visitors to the DAO for last Saturday's summer finale.

For observing nights next year and in the future, the RASC is thinking about ways to improve programming, perhaps with lectures about astronomy.

The next step is to create a non-profit entity to operate the Centre of the Universe and outreach programs at the DAO. Don Moffatt, who spearheaded last year's petition to save the Centre, has set up a Friends of the DAO - Dominion Astrophysical Observatory group on Facebook, and everyone who is interested in keeping public outreach alive at the DAO is urged join this group.

Before public activities return to the DAO next year, those of us involved in this year's successes hope to have news about the new entity and new public outreach activities on Observatory Hill. While there are many ideas being discussed for future years, we must keep in mind that the observing sessions were run by volunteers, and volunteer time is not an unlimited resource, and funds for new programs are scarce.

Everyone mentioned above deserves thanks for all the hard work they did to make this summer's observing possible. I would like to give a special thanks to  the NRC and its staff at the observatory for all their help.

This year, the RASC Victoria Centre is celebrating its 100th anniversary. In June the Victoria Centre held a hugely successful General Assembly for RASC members from across Canada, something that also involved a major volunteer effort. Once that was over, Victoria Centre members pulled off this summer's observing nights. Kudos to all the RASC volunteers for creating a memorable centennial celebration!

A Visit to Seattle's Shuttle Simulator

The Space Shuttle Simulator at the Museum of Flight in Seattle. Chris Gainor & Audrey McClellan photos.

Three years ago, the U.S. Space Shuttle program came to an end after 135 flights to Earth orbit over thirty years starting in 1981. While NASA and private companies continue to develop new spacecraft to replace the shuttle, the artifacts of the shuttle program are moving into museums around the United States.

The three remaining shuttles in the fleet went on display at the Kennedy Space Center at Cape Canaveral, the Smithsonian Institution's Udvar-Hazy Center just outside Washington, D.C., and the California Science Center in Los Angeles. Another shuttle used for flight tests but never flown in space is on display at the Intrepid Museum in New York City.

More than twenty museums had bid for the shuttles, and one of the more prominent unsuccessful candidates for a shuttle was the Museum of Flight on the south side of Seattle, alongside the King County Airport at Boeing Field.

As a consolation prize, the Museum of Flight got the full-scale shuttle simulator from the Johnson Space Center in Houston that every shuttle crew trained in as they prepared for their flights. On visits to Houston in the 1990s, I saw that the simulator was constantly in use.

After the move to Seattle, this simulator opened to the public in November 2012 in the specially-built Charles Simonyi Space Gallery, named after the Microsoft Office creator who is the only person to have paid for two trips into space aboard a Soyuz spacecraft to the International Space Station (one of Simonyi's Soyuz capsules is also on show in the gallery).

Seattle is close to my home in Victoria, and I recently had the chance to visit the Museum of Flight and the simulator.

Inside the payload bay looking toward the cabin.

The simulator includes the shuttle's payload bay, and visitors can a good sense of the shuttle's large dimensions from outside and from walking inside the payload bay, something that isn't possible with flown shuttles. Hanging above the payload bay are full-scale replicas of an Inertial Upper Stage, a Boeing rocket that was used to boost payloads from the shuttle's low Earth orbits to much higher orbits or into trajectories around the Sun, and a large scale model of the Hubble Space Telescope.

For me, the highlight of the visit was a tour of the shuttle cabin, something that is available only on weekends and holidays and for extra cost. The cabin was where most of the work was done during this simulator's lifetime, and it bears the marks of more than 30 years of wear and tear. This is the reason the number of tours of the shuttle cabin are sharply restricted. But for anyone who wants to literally follow in the footsteps of the astronauts, the extra cost of this tour is well worth the price.

Shuttle Simulator flight deck

The habitable space inside the shuttle consists of the flight deck and the mid deck, each about as big as a bathroom in an average house. The flight deck includes the cockpit where the commander and pilot sat during launch and re-entry, and a control panel at the back that includes controls for both the spacecraft and the Canadarm that moved payloads around the payload bay, which is visible out of two large windows.

Visitors can't sit in the pilot and commander seats on the tour, but next to the simulator is a computerized cockpit mockup where visitors can try their hands at landing the shuttle.

Back control panel on the flight deck. The Inertial Upper Stage is visible through the window.

Directly below the flight deck is the mid deck, which is accessed by two ladders from the flight deck (unnecessary in space when one can float between the two levels) and the side hatch of the shuttle. The mid deck is lined with lockers containing gear for the flight, the compartment containing the shuttle toilet, and access to a tunnel leading to an airlock or the space station when the shuttle and station were docked, or to scientific modules that sometimes flew in the payload bay. The mid deck, which lacks windows, served as the sleeping station for shuttle crews, who used sleeping bags.

The half-hour tour of the shuttle cabin gives one a good sense of the close quarters that crews had to deal with on shuttle missions that sometimes lasted longer than a fortnight. And these accommodations were roomy compared to the Mercury, Gemini and Apollo spacecraft that earlier astronauts flew, or even the Russian Soyuz ferries that today carry cosmonauts and astronauts to the ISS.

Note the signs of wear and tear on these mid deck lockers

In part because the United States has yet to settle on a new spacecraft to carry its astronauts into space, the shuttle still symbolizes America's space program to many people despite its retirement. The shuttle's place in history is still a matter of discussion and some controversy, something that is not addressed in this exhibit aside from information on the deaths of two crews on the shuttle.

That being said, the shuttle simulator adds a great deal to the Museum of Flight's space exhibits. The museum is best known for its great collection of vintage aircraft, including Boeing airliners produced in the Seattle area, and aircraft from the First and Second World Wars. The museum also owns a Concorde supersonic transport, and one of the Boeing 707s that served as Air Force One in the 1960s, along with a Super Constellation decked out in the livery of Trans Canada Airlines, the predecessor of Air Canada.

In part because Boeing was not as involved in early space programs and the shuttle as other contractors (some of which Boeing has absorbed in recent years), the Museum of Flight's space collection has been stronger on replicas than actual flown spacecraft.

Visitors can see full-scale replicas of the Mercury spacecraft and the Apollo Command Module and Lunar Module ascent stage. As well, the museum has a full-scale replica of the Lunar Roving Vehicle, which was manufactured by Boeing, and the Destiny module from the ISS, which visitors can walk through, along with a many artifacts from the space program, including space suits and equipment used by the astronauts.

For anyone who is interested in aircraft or spacecraft, the Museum of Flight is a must-see destination in the Pacific Northwest.

Canada's Space Story on its Stamps and Currency

Canadian stamp from 1966 honouring Alouette II

This is an updated version of an article I wrote in 2003 on Canada's stamps and currency related to space exploration.

In addition to my interest in space exploration, I also collect stamps. So it is no surprise that my collection includes stamps about space exploration. And Canadian stamps on this topic are of course of special interest.

As a semi-official form of recognition, postage stamps also reflect the interests of the government and society in general. In this case, Canadian stamps reflect the moderate degree of interest Canadians have in their own space program.

This moderate level of interest is shown in how Canada marked its early space achievements. When Canada launched its first satellite into orbit in 1962, the there was no stamp issued to mark the event. Instead, the first stamp related to Canada's space program honoured Canada's second satellite.

A five-cent commemorative stamp featuring Alouette II was issued on January 5, 1966, a few weeks after the satellite's launch. Yet no Canadian stamp was ever issued for Alouette I. In the absence of another explanation for ignoring this "first," it appears that politics was involved.

Back in the 1960s, Canada had a conservative stamp issuing policy, and the post office was a government department headed by a politician who sat in cabinet.

In 1962, when the first Alouette was launched, John Diefenbaker's Progressive Conservative government was on its last legs and was replaced a few months later by a new Liberal government under Lester Pearson. The Conservatives never took the opportunity to honour the first Alouette with a stamp, and the Liberals waited to put out a stamp until a satellite had been launched on their own watch.

Both Alouettes conducted research on Earth's ionosphere, a layer of the atmosphere that reflects radio waves. In the days before communications satellites, the ionosphere and its changes had major impacts on long-range communications.

Prior to the Alouette stamp, only four Canadian stamps contained any reference to outer space. A 1953 wildlife set included a polar bear on a two-cent stamp with a background suggestive of the Aurora Borealis, and a 15-cent definitive issued in 1954, showed a Gannet flying in front of the Big Dipper and Polaris, the North Star. Canada's two 1964 Christmas stamps depicted the Star of Bethlehem.

Three other stamps from this period also relate to space. Canada joined the U.S. and other countries in issuing a special stamp for the International Geophysical Year of 1957-1958, an event closely tied to the birth of the space age. Canada's stamp shows a microscope and a globe. Another 1957 commemorative shows explorer David Thompson using a sextant.

And on February 23, 1959, a five-cent commemorative honoured 50 years of flight in Canada with a design showing the Silver Dart, the first aircraft to fly in Canada, and three jet aircraft that bear a striking resemblance to the CF-105 Avro Arrow. This stamp design is rich with irony because the Arrow had been cancelled just three days before the stamp came out. Only five of the Arrows ever flew, and 32 engineers who lost their jobs when the Arrow was cancelled moved south and found work with the U.S. National Aeronautics and Space Administration, where they played important roles in the Mercury, Gemini, Apollo and Space Shuttle programs.

After the Alouette stamp, Canadian space stamps were few and far between for nearly two decades. An Olympic ceremonies set issued at the time of the 1976 Montreal Summer Olympics shows a communications satellite on the eight-cent value between two Olympic torchbearers. A communications satellite appeared 10 years later in the Expo 86 set marking the World's Fair in Vancouver.

1986 Canadarm Stamp

In 1985, Canada honoured the flight of its first astronaut, Marc Garneau, with a 32-cent Canadians in space stamp. In 1986, a set of Canadian technical achievement stamps included one featuring the Canadarm or shuttle Remote Manipulator System that has been an integral part of the space shuttle. Another stamp in the set depicts the g-suit, which is widely used by pilots and astronauts to protect against blackout.

Canada issued two 42-cent space achievement stamps that are probably its best known space stamps. One stamp showed the Anik E2 communications satellite, and another stamp bore a hologram showing the Space Shuttle above Canada. The hologram stamp, Canada's first, is popular with collectors because of its many varieties.

Later in the decade, a technology set issued in 1996 included an aerospace technology stamp, but the design emphasized the "aero" part of the term. The design of the 1995 stamp commemorating the 125th birthday of the Province of Manitoba includes a Black Brant sounding rocket that is produced in Winnipeg by Bristol Aerospace.

Five of the 68 stamps in Canada Post's Millennium Collection set in 2000 touch on space themes. The Canadian space program stamp depicts the Alouette, ISIS, Hermes, Anik and RADARSAT satellites, along with the Canadian remote manipulator system installed on the International Space Station. The Space Shuttle appears on a stamp featuring the Imax film technology developed in Canada, and a communications satellite is shown on a stamp featuring Canada's largest telecommunications company, Bell Canada Enterprises. Canadian inventor George Klein, whose inventions include the STEM (storable tubular extendible member) antenna used on Canadian and American spacecraft, appeared on his own stamp. And Abraham Gesner, the inventor of kerosene, also has a stamp in this set. The invention of kerosene, which was used in the Saturn V and many other rockets, was also honoured with a Canadian 37-cent stamp in 1988.

Later in 2000, Canada Post issued a set of four Stampin' the Future stamps, which included two with a space theme. The stamps were designed by children and are similar to an American set issued at the same time to coincide with the World Stamp Expo 2000.

In 2002, a set of stamps featuring tourist destinations included a $1.25 stamp showing the Aurora Borealis, which draws tourists to Canada's north. A 48-cent stamp honouring St. Mary's University in Nova Scotia shows a student at a telescope.

Canada Post put out its largest issue of space stamps ever on October 1, 2003, when it honoured the eight Canadian astronauts who have flown in space with a sheet of eight self-adhesive stamps that include holographic stamping and micro-embossing. The 48-cent stamps represent missions flown on NASA space shuttles by Canadian astronauts Marc Garneau, Roberta Bondar, Steve MacLean, Chris Hadfield, Robert Thirsk, Bjarni Tryggvason, Dave Williams and Julie Payette. The bottom of the sheet depicts one of the high points of Canada's space program, the "handshake" between the Canadian-built robot arm on the shuttle Endeavour and the Canadarm2 aboard the International Space Station.

Roberta Bondar Stamp from 2003

Like the hockey all-star sets around that time, the astronaut set broke Canada's traditional prohibition on stamps for living persons outside of the Royal family. That rule was been officially lifted after that time, and since then many other living Canadians have appeared on our stamps.

Canada's role in creating a satellite-borne system to assist in search and rescue operations was acknowledged in a set of four search-and-rescue stamps issued on June 13, 2005. The four stamps depict search-and-rescue operations, along with a Russian Nadezdha or COSPAS satellite, and an American NOAA Polar Orbiting Environmental Satellite. Both satellites also appear on the margins of the issue's miniature sheet. In 1979, the U.S., the Soviet Union, Canada and France set up the COSPAS-SARSAT satellite rescue system in a rare example of Cold War cooperation. Canadian-built search-and-rescue receivers were put on U.S., Russian and French satellites, and the system began operation in 1982.

On June 30, 2006, Canada Post marked the 100th anniversary of the Atlas of Canada with a 51-cent stamp. The stamp has no space theme, but the margin of the stamp's pane shows a satellite orbiting the Earth to obtain data from Earth orbit for today's Atlas of Canada. The "satellite" closely resembles the Pioneer 10 and 11 spacecraft, which were launched in the 1970s and explored Jupiter, Saturn and the outer Solar System.

Although Canada has a strong tradition of excellence in astronomy, it was only in 2009 that Canada issued its first stamps dedicated to the science. On April 2, Canada Post put on sale two 54-cent stamps and a souvenir sheet in honour of the International Year of Astronomy. The year was celebrated to mark 400 years since telescopes were first pointed at the skies.

One stamp shows the Horsehead Nebula in Orion and the Dominion Astrophysical Observatory near Victoria, B.C., which was the world's largest telescope for a few months after it was completed in 1918. The other stamp shows the Eagle Nebula in Serpens and the Canada-France-Hawaii Telescope on the summit of Mauna Kea on the island of Hawaii, which began operations in 1979. The margin of the souvenir sheet and a booklet containing the stamps also contain photos of other astronomical objects.

In recent years, Canada Post has issued definitive stamps featuring Canada’s maple leaf flag. A set of five “permanent” domestic rate stamps issued in January 2011 included a design showing the Canada wordmark, which incorporates the flag, on the Canadarm in space. The five stamps were issued in booklets of ten self-adhesive stamps and in souvenir sheet form.

In 2011, 2012 and 2013, Canada Post issued stamps featuring the twelve signs of the zodiac. The four constellations depicted each year included traditional drawings of the constellation sign overlaying a star map of the constellation. The dozen stamps, all with a "permanent" domestic rate value, were issued in booklet and souvenir sheet forms.

Other Countries

Canadian space achievements have also made their way onto stamps from other countries.
In 1968, Barbados issued a set honouring World Meteorological Day that included a stamp depicting a large cannon built by a Canadian team headed by Dr. Gerald Bull.

The High Altitude Research Program (HARP) launched projectiles into high trajectories, but funds were cut off before Bull could attempt a satellite launch using the cannon. While some research was conducted at a site on the U.S.-Canada border in Vermont and Quebec, a cannon was built in Barbados with help from the U.S. military.

In 1987, the Soviet Union marked the success of the COSPAS-SARSAT search-and-rescue program with a souvenir sheet.

From the U.S., the 1981 space achievements set of 1981, and the $3.00 Challenger stamp of 1995 show the Canadarm on the shuttle, and the Canadarm appears on shuttle stamps from other countries, notably Germany's 1975 shuttle definitive. Alouette was featured in a 1966 Polish space set and a 2012 souvenir sheet from Mozambique. Marc Garneau, Canada's first astronaut, appeared on the Gambia's sheet of stamps in 1994 marking the 25th anniversary of Apollo 11.

Covers

Because all Canadian satellites and astronauts have been launched outside Canada, commemorative envelopes or covers marking these launches are available with cancellations from these foreign launch sites. An Alouette I launch cover from its Vandenberg Air Force Base launch site in California is illustrated.

Commemorative "tracking" covers from Canadian locations exist for early U.S. human space flights, especially Apollo flights. These covers are of limited value because no U.S. human spacecraft flew over Canadian territory until the Skylab program in 1973.

More information on space stamps is available from the website of the Space Topic Study Unit in the U.S. and the Astro Space Stamp Society in the U.K.

The best online source of information on Canadian stamps is the Canadian Postal Archives.

Coins and Currency

A Canadian spacecraft made its first appearance on our paper currency on a $100 bill that the Bank of Canada circulated from 2004 to 2011. The back of the bill showed RADARSAT-1 flying over a map of Canada.

In 2013, Canada's new $5 bill was put in circulation, complete with a depiction of a spacewalking Canadian astronaut near Canada's contribution to the ISS - the Dextre remote manipulator hand and Canadarm2. The design was unveiled by Canadian astronaut Chris Hadfield during his stint in 2013 as commander of the ISS.

Four Canadian coins also relate to space. A $20 coin issued in 1996 as part of a series marking the history of Canadian aviation depicts the Avro Arrow and Jim Chamberlin, who helped design the Arrow and went on to design the Gemini spacecraft for NASA. In 2006, the Royal Canadian Mint honoured astronaut Chris Hadfield's installation of Canadarm2 on board the International Space Station with two coins, one a $300 gold coin and the second a $30 silver coin. For the International Year of Astronomy in 2009, the mint issued a $30 silver coin.

Looking Back at Our First Close-up of Saturn

This entry records my impressions from my visit in November 1980 to the Jet Propulsion Laboratory in Pasadena, California, for Voyager 1's encounter with Saturn. It is adapted from an article I wrote for Spaceflight magazine in August, 2004, on the occasion of the Cassini spacecraft's arrival in orbit around the ringed planet. In the ten years since, Cassini and the Huygens spacecraft it dispatched to the surface of Titan in 2005 have further revolutionized our views of the Saturnian system.


Cassini's arrival at Saturn marked the first visit by a spacecraft to the ringed planet in nearly 23 years. Only three spacecraft had gone there before, all of those visits taking place in a narrow two-year time span – Pioneer 11 on September 1, 1979, Voyager 1 on November 12, 1980, and Voyager 2 on August 26, 1981.

Pioneer 11’s mission was mainly as a pathfinder, proving that spacecraft could survive the rigors of passages through the asteroid belt, the Jovian and Saturnian magnetic fields, and Saturn’s ring plane. Its primitive imager gave scientists and the public only a taste of the views Jupiter and Saturn offered.

Both Voyagers had passed by Jupiter in 1979, providing stunning views of the planet and its moons, most memorably the active volcanoes on Io. As Voyager 1 approached Saturn in the fall of 1980, more than the usual amount of anticipation was in the air at the Jet Propulsion Laboratory in Pasadena, California.

Much of the future of planetary exploration hinged on the success of this encounter, because Voyager 1 had the dual mission of passing close to both Saturn and its moon Titan, the only moon in the solar system known in 1980 to have an atmosphere.


Titan's importance was shown by the fact that Voyager 1's path by Titan would direct it away from the orbital plane of the other planets. Only if Voyager 1 succeeded in getting data from Titan on its way in toward Saturn would Voyager 2 be freed to take a path by Saturn that would direct it to Uranus and hopefully Neptune. A failure of Voyager 1’s Titan encounter would mean that Voyager 2 would be directed to pass close to Titan, and that path would exclude further Voyager planetary encounters.

We know today that both Voyagers succeeded – Voyager 1 obtained its crucial data from Titan and Voyager 2 visited in its turn Saturn, Uranus and Neptune. Voyager 1’s encounter with Titan wound up raising more questions than it answered, and those questions inspired the European Space Agency to send the Huygens probe to Titan's surface in 2005 after riding aboard  Cassini to the Saturnian system.

I was privileged to be one of the journalists at JPL covering Voyager 1’s dramatic encounter with Saturn and Titan, and my memories of that event provide an interesting backdrop to the discoveries that Cassini and Huygens have been making. In a dispatch to my newspaper, I described the findings of those few days in November 1980 as a “knowledge explosion.”

When it came to coining superlatives to describe the encounter, I had plenty of competition.  In addition to the scientists and engineers at JPL, there was a crowd of nearly 1,100 reporters and science fiction fans, including a number of celebrities, whose activities were chronicled by a reporter from People magazine.

Science fiction great Ray Bradbury came to JPL and declared: “This is another of those days that will be remembered a billion years from now. We are privileged to be here and be a part of it.”

Carl Sagan, then at the height of his fame as the star of television's Cosmos, rubbed shoulders with the media horde to shoot segments for a news programme on an American TV network. Many past leaders of the space program, including former JPL director William Pickering, joined the crowd. A large British media delegation was headed by Patrick Moore.
California Governor Jerry Brown spent several hours at JPL on encounter day, accompanied by his science advisor, former Apollo astronaut Rusty Schweickart.

Brown repeated his contention, which even then sounded tired, that "resource efficiency and technological innovation are the keys to the future."

One of the biggest celebrities was a short, stooped man with a shock of white hair,
Clyde Tombaugh, who 50 years earlier had discovered Pluto. He autographed copies of his new book on a recent spate of discoveries about the planet he had discovered as a young man.

Most of the information was given out in daily morning press briefings, which drew standing room only crowds to JPL's von Kármán Auditorium. After scientists presented the latest photos and other data, journalists vied with one another for the first and best questions.
A large model of Voyager dominated one wall of the auditorium, and formed the backdrop for television news reporters and interviews. The crowds grew and contracted in direct relation to the proximity of the Nov. 12 encounter.

There was activity in the press area almost around the clock that week as Voyager 1 sent home a seemingly ceaseless stream of photographs that flashed in their raw forms onto television screens at the Voyager control centre at JPL.

Following the daily press briefings, reporters lined up to pick up their own copies of the best images. The photo office just outside the auditorium was adorned with a cartoon showing a hand clutching a photo of Saturn sticking out of an ocean surface, circled by shark fins. Most reporters still used typewriters and telephones to file their stories, since the internet, word processors, portable computers and even fax machines were still in the future.

Even before most reporters arrived for the encounter, Voyager 1 had sent back dramatic photos showing the structure of Saturn’s rings, including ringlets and hundreds of divisions that showed the rings to be similar to a phonograph record. Late in encounter week, scientists had found between 800 and 1,000 ringlets circling Saturn within the six major ring systems extending 480.000 kilometres from Saturn.

As Voyager flew by, the rings had more stunning surprises. The Cassini Division and the Encke Division were found not to be gaps in the rings at all, but ring systems that do not reflect as much light as brighter rings.

Intertwined "braids" and “knots” in the outermost ring appeared to defy the laws of orbital dynamics. “Spokes" were found in Saturn's major ring, apparently caused by interaction between the rings and Saturn's magnetic fields. Talk of shepherd moons filled the air at JPL.
“In this strange world of Saturn’s rings, the bizarre becomes commonplace,” said Dr. Bradford Smith, the head of Voyager’s imaging team.

Saturn's atmosphere defied predictions that it would be topped by haze, and instead revealed Jupiter-like bands, storms and spots.

Saturnian moons Mimas, Enceladus, Tethys. Dione. Rhea, Hyperion and Iapetus, were found to be made up mainly of ice, and all with the exception of Enceladus, which was not well placed for Voyager 1’s cameras, were seen to be peppered with craters.

Mimas, the closest large moon to Saturn, was photographed with a crater 130 km across, one quarter the diameter of Mimas. A photo of the crater and its central peak drew gasps at a press conference and a comment from Dr. Smith: “This is not an optical illusion.” Soon photocopies of the Mimas photo, complete with additional lines to make the moon look like a dead ringer for the Death Star from Star Wars, circulated around JPL and elsewhere.

The photos of Titan, on the other hand, were a disappointment. Titan's orangeish atmosphere obscured the surface. But Voyager’s instruments found Titan’s atmosphere to be deeper and denser than expected. Expectations of a methane atmosphere were dashed when Voyager’s instruments showed that Titan's atmosphere is made up mainly of nitrogen, the element that makes up 78 per cent of Earth's atmosphere. Methane makes up a few percent of Titan's atmosphere and dominates the haze atop Titan's clouds.

Titan, which long had been thought to be the largest moon in the Solar System, lost its title due to Voyager’s measurements to the Jovian moon Ganymede, although the matter remained in some question pending information on Neptune’s moon Triton.

As Voyager 1 moved away from Saturn, Dr. Smith proclaimed himself “stunned” by the images. “I cannot recall being in such a state of euphoria over any previous planetary encounter. We have learned more about the Saturnian system in the last week than we had in all previous recorded history.”

The amazing photos and data from Saturn and Titan opened the door for Voyager 2 to fly on to Uranus and Neptune. And the following August when Voyager 2 arrived at Saturn, the crowds of press and celebrities at JPL were even larger than for Voyager 1.

But despite Voyager’s success, apprehension hung over JPL the week Voyager 1 went by Saturn. Everyone knew that Voyager 2’s Saturn encounter would be the last planetary encounter by a U.S. spacecraft for at least five years. It was already being labelled by some pessimists as "the last picture show.”

The U.S. space program was ending a decade that began with the heights of Apollo on the Moon and Mariner at Mars, followed by years of cuts that grounded both NASA’s human and planetary programs.

President Jimmy Carter had shown little interest in space exploration during his term of office. And eight days before Voyager 1’s arrival at Saturn, Carter had been defeated in the 1980 presidential election by Ronald Reagan, who ran on a platform of major reductions to government spending.

 As a result, concerned NASA officials were present in force in the von Kármán Auditorium to court reporters in hopes of tapping public support.

 Angelo Guastaferro, NASA's director of planetary programs, surprised many reporters when he asked them for suggestions on how NASA could improve its image and get support for more missions to the planets.

And a press conference marking the culmination of the Voyager program became a discussion of the causes of the looming hiatus in planetary exploration.

Bruce Murray, then the director of JPL, said Voyager showed the potential of what America can do, but explained the hiatus this way: “As a people, we broke our concentration.”
Andrew Stofan, another NASA official, blamed over-optimism in the development of the space shuttle, which was then still five months away from its first flight. While the vast amounts of money needed to develop the shuttle in the 1970s starved other programs, Stofan added that NASA had ordered only enough large launch vehicles to support programs until the shuttle was due to begin flying in 1979.

Guastaferro said one casualty of the Shuttle delays was the Galileo spacecraft, which had been scheduled for a shuttle launch in 1982 toward a mission in orbit around Jupiter.
The NASA officials also discussed how shuttle problems were delaying the Solar Polar mission, a two-spacecraft international effort, and how political problems were besetting the Venus Orbiting Imaging Radar (VOIR) spacecraft.

"What scientists want to do in the later part of this century will be more difficult to describe and defend" than the Voyager missions or the 1976 Viking landings on Mars, said NASA’s John Naugle. Those future missions included a Saturn orbiter, a Titan orbiting imaging flight, and encounters with comets. NASA was talking with European nations about sending a mission to Halley's comet in anticipation of its close approach to the Sun and Earth in 1986.

As we know now, NASA’s planetary exploration program was put on the back burner for most of the 1980s, with the exception of Voyager 2, which encountered Uranus in 1986 and flew by Neptune and its moon Triton in 1989. Voyager 2 found Triton to be smaller than Jupiter’s four large moons and Titan, although Triton was found to possess a thin atmosphere.

NASA did not launch any new planetary missions until 1989, when the shuttle returned to service following the Challenger disaster in 1986.

Galileo was launched that year and it didn’t begin its mission at Jupiter until 1995. The Solar Polar Mission was reduced to the European Ulysses spacecraft, which was launched from the shuttle in 1990. VOIR was replaced by the less ambitious but very successful Magellan spacecraft, launched by the shuttle in 1989. A European spacecraft is exploring Venus from orbit today, and an American spacecraft is orbiting Mercury.

NASA never did launch a craft to Halley’s comet, but European, Soviet and Japanese spacecraft probed the comet, followed by NASA spacecraft that have since visited other comets. This week the European Rosetta spacecraft went into orbit around a comet.

After a two-decade hiatus interrupted only by the failed Mars Observer spacecraft, NASA returned to Mars in 1997. Among the many spacecraft that have gone to Mars since then, two rovers are today roaming the surface of the red planet.

And now Cassini is entering its second decade of exploring the Saturnian system. Together with Huygens, Cassini picked up on the exploration of Titan where Voyager 1 left off in 1980. In less than a year, the New Horizons spacecraft will give humanity its first close-up view of Pluto.
