Mariner 4 solar panel testing

September 30, 2014

The Mariner Mars mission was on a tight schedule in 1964, so testing was not quite as extensive as it was for other missions. A full-size temperature-control model and a proof-test model went through a series of environmental and vibration tests in the 25-foot space simulator at NASA’s Jet Propulsion Laboratory and other test facilities. This photo was taken in June 1964, outside of the Spacecraft Assembly Facility at JPL. In this unusual outdoor setting, the solar panel test took place in a large plastic tent. After testing was completed, two spacecraft and a spare (the proof-test model) were partly disassembled, carefully packed and loaded on moving vans for a trip to the Air Force Eastern Test Range in Cape Kennedy, Florida. They were inspected, reassembled, and tested again before launch.
