William Pickering became involved with the Jet Propulsion Laboratory (JPL) in 1944, during the Second World War.
As the Director of JPL, from 1954, Pickering was closely involved with management of the Private and Corporal missiles under the aegis of the U.S. Army.[1]
In 1958 the lab's projects were transferred to the National Aeronautics and Space Administration (NASA) and Pickering's team concentrated on NASA's unmanned space-flight program. JPL, under Pickering's direction flew further Explorer 3 and Pioneer missions as well as the Ranger and Surveyor missions to the moon and the several Mariner flybys of Venus and Mars.
Explorer III discovered the radiation field round the earth that is now known as the Van Allen radiation belt. Explorer 1 orbited for 10 years and was the forerunner of a number of successful JPL earth and deep-space satellites. William Hayward Pickering is not to be confused with William Henry Pickering, an astronomer from an earlier era.
At the time of his retirement as director, in 1976, the Voyager missions were about to launch on tours of the outer planets and Viking 1 was on its way to land on Mars.
Retirement
Pickering, keen to support authentic science in his home country, was Patron of New Zealand's only school-based research group, the Nexus Research Group, from 1999 until his death in 2004.
Between 1977 and his death in 2004, Pickering also served as Patron of the New Zealand Spaceflight Association; a non-profit organisation that existed from 1977 to 2012 to promote an informed approach to astronautics and related sciences.[citation needed]
Gifford Observatory
Pickering re-opened the Gifford Observatory as the guest of honour, on 25 March 2002.[4] He had been a frequent user of the observatory during his school days in Wellington College.
IEEEEdison Medal in 1972, For contributions to telecommunications, rocket guidance and spacecraft control, and for inspiring leadership in unmanned exploration of the solar system.
Three roads in New Zealand have been named after Pickering, namely: Sir William Pickering Drive in the Canterbury Technology Park in Christchurch; Pickering Crescent in Hamilton; and William Pickering Drive in Auckland.
In December 2018 New Zealand company Rocket Lab announced that the fourth launch of their Electron rocket and their first mission for NASA's Educational Launch of Nanosatellites programme will be named "This one's for Pickering", in honour of Bill Pickering.[11]
