The death last year of Neil Armstrong has driven home the
reality that the space race that culminated with Armstrong’s first step on the
Moon has passed into history. In 2012 we
also lost two notable astronomers whose roles in that cosmic competition have
not often been remarked upon.
Sir Patrick Moore, who died at age 89 on December 9, and Sir
Bernard Lovell, who passed away August 6, not long before what would have been
his 99th birthday, had many things in common, including being
Englishmen who made major marks on astronomy, their skill as musicians, and
their love of cricket. While their names today mean little to people outside
the United Kingdom, in the 1960s both were well known in Canada, even outside
astronomical circles.
Lovell spearheaded the creation of the gigantic 76-meter
radio telescope at Jodrell Bank in Cheshire, and in so doing became one of the
founding fathers of radio astronomy. He gained fame and may have saved his
astronomy program by using his telescope to track early space vehicles.
Moore was famous in the UK for the 55-year-long run of his
monthly BBC television show, The Sky at
Night. Because this show did not appear on Canadian television, Moore was
best known here as a prolific writer on astronomy and space travel. Rare was
the Canadian space enthusiast in the 1960s and 1970s who didn’t own a copy of
at least one of his books. In my case, it was his Moon Flight Atlas.
While the claim in one British obituary that Moore was the
world’s most famous astronomer is debatable, he was probably the world’s most
famous amateur astronomer. He had come to his interest in astronomy in his
childhood, but gave up his admission to Cambridge University to join Bomber
Command as a navigator in World War II.
After the war, he turned to teaching, observing, and writing
the first of his books, which with various editions and translations number in
the hundreds.
In the 1950s and 1960s, Canada had much stronger political,
economic and cultural links to Britain than it does today. Canadians in those
days read more British books and periodicals than they do today, and English
Canadian broadcasters used British radio and television shows that were never
broadcast in the U.S. or shown there only once they had won popularity in
Canada. So it was no accident that Moore became well known in English Canada at
the time.
Moore had trained in Hamilton, Ontario, for his wartime
service, but his postwar visits to Canada were rare – a fact that he regretted
when he met a group of RASC members in Toronto in 1985.
Although younger Canadian astronomers may not know the name
of Patrick Moore, many of them learn the wonders of the deep skies with the
help of the Caldwell Catalogue of 109 deep sky objects that is named after
Moore, its creator, whose full last name is Caldwell-Moore.
Moore was also involved in the rise of space travel. It has
been widely noted that The Sky at Night debuted
just a few months before the launch of Sputnik in 1957, and the show benefited
from the explosion of interest in space that came with the space race that
began with Sputnik and culminated with Armstrong’s and Buzz Aldrin’s landing on
the Moon in 1969.
Even before Sputnik, in 1956, Moore had signed on as the
first editor of Spaceflight magazine,
the flagship publication of the British Interplanetary Society (BIS) that
remains today the English-speaking world’s most popular magazine dedicated to
space exploration.
As an expert on the Moon, Moore encouraged its exploration,
and he helped present the BBC’s live television coverage of the Apollo flights
to the Moon. Many astronauts and cosmonauts appeared on The Sky at Night, including Neil Armstrong.
After those flights ended four decades ago, Moore continued
to the end of his life to feature spacecraft that explored the solar system and
probed the heavens. When Voyager 1 flew by Saturn and its moon Titan in 1980, I
attended the encounter at the Jet Propulsion Centre, and a highlight for me was
meeting Moore, who was there to gather material for his show and his books.
By the time of that long ago encounter, Sir Bernard Lovell
was nearing retirement. Lovell’s passing in August was not as widely noted as
Moore’s in part because Lovell has been out of the public eye for decades.
Lovell was director of the Jodrell Bank Observatory in 1952
when construction began on the Mark 1 telescope, which became the world’s
largest steerable radio telescope. By the time the telescope was completed in
the summer of 1957, it was well over budget and the subject of an investigation
by the Public Accounts Committee of the House of Commons.
When Sputnik was launched that fall, the Jodrell Bank
telescope was used to track Sputnik’s booster rocket by radar, proving its
utility to skeptical politicians and members of the public, including a rich
benefactor who paid off the remaining deficit on the telescope’s construction.
In those early days of space travel, both Soviet and
American space authorities called on Jodrell Bank to track spacecraft sent to
the Moon, Venus and Mars, and the British media became frequent visitors to the
radio telescope. In 1961 Lovell was knighted, formalizing the fact that his
telescope had become a source of national pride.
Lovell’s – and Jodrell Bank’s – moment of greatest
international notoriety arrived in February 1966 when the Soviet Union’s Luna 9
became the first spacecraft to land intact on the Moon.
Not long after Luna 9 sent back its first data from the
lunar surface, the nature of the signal changed and personnel at Jodrell Bank
recognized it as being similar to signals used to transmit photos to newspapers
(and later used for fax machines) because Jodrell Bank had previously been
involved in communications experiments with the Echo 2 balloon satellite. When
Lovell noted the nature of Luna 9’s signals to newspaper reporters who had come
to Jodrell Bank, the Daily Express
brought a facsimile machine to the telescope and used it to produce images from
the surface of the Moon when Luna 9 transmitted more photos the next day.
The Luna 9 photos appeared in the Express and other British newspapers before the discomfited
Russians could release them, and Lovell became for a brief time an
international celebrity.
Only a small fraction of Jodrell Bank’s operating time was
used to track spacecraft, however, and Lovell and his team made many
contributions to astronomy, from the nature of cosmic rays and meteorites to
groundbreaking work on quasars and pulsars. The Mark 1 Telescope at Jodrell
Bank was eventually named in Lovell’s honour, and continues to operate today.
Only two steerable radio telescopes are larger than the Lovell Telescope.
In October 1971, when Lovell visited Edmonton to speak at
the University of Alberta, he drew a crowd of more than 800 curious members of
the public, including this writer. As in the case of Moore, I believe that
Lovell’s fame in Canada at the time was related to Canada’s closer links to the
UK at the time, as well as his association with the exploration of space. Like
Moore, Lovell was a prolific author.
In an account of his speech in the Edmonton RASC Centre
publication Stardust, Lovell
expressed the hope that more resources would be put into basic space research
such as he was doing and less into spaceflight technology. No doubt Lovell’s
concern about the emphasis on space technology was related to the space race’s
emphasis on political competition at the expense of science.
The Cold War and the space race between the United States
and Russia are over, and today many orbiting telescopes and spacecraft that
explore the solar system have taken their places among the tools used by
astronomers to do their work, alongside optical and radio telescopes. Sir
Patrick Moore and Sir Bernard Lovell advanced astronomy not only with their
work as astronomers but also through their roles in the 1960s space race that
helped vault them both to fame.
