A brief history of William
Pickering,
Explorer 1 engineer, JPL director, kiwi scientist, and patron of the
Nexus Research Group.
New Zealand's famous Rocket Man. (1910 -
2004)
Most
New Zealand children, at some stage of their school education, will
have heard of Mount Everest conquerer Sir Edmund Hilary and atom
splitter Sir Earnest Rutherford. These men symbolise the pioneering and
problem-solving spirit of Kiwi culture, neither man willing to blindly
accept the perceived limitations of world they lived in. One man
conquered the very large, the other the unimaginably small.
Our
children learn that being geographically isolated at the bottom of the
planet, with relatively few resources, does not have to prevent us from
having a major impact on the rest of the world. Movie maker Peter
Jackson (maker of Lord of the
Rings) has shown that from small
beginnings, with enough determination, anyone in New Zealand can make
it to the top of their profession.
There
is one other historic achievement that seems to have gone unnoticed in
our school curriculum resources ...that of the work of Dr Sir William
Pickering. He played a major role in conquering space - the "final
frontier". It was a New Zealander who brought the unimaginably distant
planets within our reach.
So
what kind of education and training did Bill Pickering have? From his
example, is it still possible for Kiwi students to one day make a
valuable contribution to Space Research?
The Early Years...
William
Hayward Pickering was born in Mount Victoria, Wellington in 1910. His
mother died when he was six and he was sent to live with his
grandparents in the Marlborough Sounds. Even at this early age Bill
already had something in common with Sir Earnest Rutherford. Both men
attended Havelock Primary School.
In
1923 he started boarding at Wellington College. Bill found his
inspiration to look at the stars from his maths teacher, the founder of
the school's observatory. Wireless communications also became a hobby
with Bill building an amateur radio station.
Bill
eventually made it to the United States, and by 1936, he had received a
Bachelor of Science, Master of Science and a Ph.D. in Physics from
Caltech.
He
joined the Caltech faculty and by 1946 was Professor of Electrical
Engineering. During World War II, he conducted research on the
absorption properties of cosmic rays with Dr. Robert A. Millikan (Year
12 & 13 physics students - this is the Millikan of the oil drop
experiment/charge on an electron fame). Pickering was invited to the
Jet Propulsion Laboratory (JPL) in 1944. He was named chief of JPL's
Remote Control Section and by 1949, headed the Corporal and Sergeant
missile programs. He became Director of JPL in 1954.
Earth Escape
In
conventional warfare, if you can control the skies you can control any
country. An invading force can have its aircraft fly into another
country's skies - its "air space" - and win a battle without the use -
or loss - of ground troops. However, enemy aircraft can be spotted and
heard from a distance, anti-aircraft guns can then shoot the invaders
down. But what if you had a craft - a satellite - that flew so high in
the atmosphere that nobody could see it was there? Even when over head,
they cannot be heard, cannot be seen. They are out of reach of
anti-aircraft guns. You can easily invade any air space; spy and take
photos of the country below or fire weapons straight down that would
strike with no warning or chance to mount a defence.
By
the mid 1950's both Russia and America were working on vehicles that
could escape the earths surface and reach the edges of our atmosphere.
Satellites are launched by rockets, able to circle the planet like
miniature moons. The race to dominate sky and space began in earnest
when the Russians launched Sputnik
in 1957 using newly
developed rockets. Circling the globe every 90 minutes, the Sputnik
satellite contained a beeping transmitter that could be heard on any
short wave radio on earth. The American public knew it was there. In their
air space! Terror struck the nation and its Government.
Bill
Pickering said: "It was only the beeping reality of Sputnik
that suddenly made the threat of intercontinental atomic warfare with
ballistic rockets more than a science fiction story."
The
US Navy was given a large budget to challenge the Russians lead in the
Space Race. The US must
have working rockets! A test launch, on
December 7th, 1957, was eagerly awaited. Under the full glare of the
international media, Vanguard
blew up on the launchpad.
Meanwhile
the Jet Propulsion Laboratory (JPL) had been working since Sputnik
on their own satellite delivery system, albeit with a smaller budget.
Working with Pickering was a cosmic ray expert, Dr James Van Allen, and
Dr Wernher von Braun. It was Von Brauhn's work as a rocket scientist
that enabled the Nazi's to launch the deadly V2 rocket that devastated
London during World War II.
Their
rocket, Explorer 1,
was launched from Cape Canaveral, Florida on
January 31, 1958, less than four months after Sputnik
and just
seven weeks after the Vanguard
disaster. It was Explorer 1
that made the discovery that a radiation belt circled the Earth. This
would become known as the Van Allen Belt. Explorer
1 stayed in
orbit for the next 10 years.
The launch of NASA...
Once
Pickering and his team conquered the earth's orbit, no part of the
planet was blind to American eyes, nothing stood between America and
the far reaches of space. In 1958 Congress passed the Space Act that
established the National Aeronautics and Space Administration (NASA).
JPL was transferred to NASA and charged with robotic exploration of the
moon and planets.
NASA
was given three broad categories for their space missions:
1.Near
Earth
Satellites.
To make
measurements of: the Earth from space; to explore the near Earth space
environment; and explore the cosmos from observing points above the
Earth's atmosphere
2.Deep
space
missions
to explore
the solar system
3.The
development of manned space travel.
Bill
Pickering said in 1993: "JPL argued for, and received, a charter to
develop the deep space missions. As a personal aside, I was delighted
to hold a contract that said in essence 'go out and explore the depths
of the solar system'."
During
his 22 years as JPL Director:
Explorer
I, the
first U.S
satellite, was launched
the Ranger
missions took the first close-up high resolution pictures of the Moon
Surveyor
craft
landed on the Moon
various
space craft were
sent to Mercury, Venus and Mars
plans
for Voyager's
Grand Tour were underway.
Pickering
retired from JPL in 1976.
Dr Bill Pickering with Ranger,
the probe
that took TV pictures of the Moon as it crashed into the surface!
The Legacy continues...
Retirement
did not mean that Bill's influence was forgotton. Almost thirty years
after he retired Bill was awarded the inaugural Francois-Xavier Bagnoud
Aerospace Prize in 1993 for his contribution to space science.
Congratulated by His Majesty, the Emporer of Japan, Dr Pickering was
named a Japan Laureate in 1994, "For inspirational leadership in
unmanned lunar and planetary exploration, and for pioneering
achievements in the development of spacecraft and deep space
communications". Of this prestigious award, the President of Caltech,
Dr Thomas Everhart said: "More than any other individual, Bill
Pickering was responsible for America's success in exploring the
planets - an endeavour that demanded vision, courage, dedication,
expertise and the ability to inspire two generations of scientists and
engineers at the Jet Propulsion Laboratory." Added Dr Edward Stone, the
Director of the Jet Propulsion Laboratory, "The Japan Prize is a well
deserved recognition od Dr Pickering's many contributions to space
science and his leadership and vision in shaping JPL as the foremeost
explorer of the solar system".
The Present...
Prior
to his death in March of this year, Dr William Pickering KBE was still
very active. We appreciated his support as Patron of the Nexus Research
Group. He received an Honorary Knighthood and in the Queen’s
Birthday Honours 2003 the Wellington-born scientist was made an
Honorary Member of the Order of New Zealand. In that same year the
Pickering/Rutherford Memorial was unveiled in Havelock; two great
scientists to inspire our students!
As
a former member of the Nexus Research Group Dr Pickering continues to
inspire us today.
