A test model of the Applications Technology Satellite (ATS) is seen during checkout activity in Chamber A of the Space Environment Simulation Laboratory at the Johnson Space Center (JSC) to see if the satellite's 30-feet diameter umbrella-shaped antenna would unfold properly in a space vacuum. The antenna is in an unfolded (deployed) position in this picture. For the test, the 65-feet diameter by 120 feet high vacuum chamber in Building 32 was pumped down to an equivalent altitude of 255,000 feet. The test model satellite is hung by cables from the chamber's dome. Engineers from the Goddard Space Flight Center (GSFC) not only wanted to test the antenna mechanism itself, but the efforts of the unfolding action on the whole satellite. For the test, the 54-feet span solar array "paddles" for generating the satellite's electrical power were spread in the orbit flight position, while the parabolic antenna was folded into a donut-shaped package beneath the solar ray booms. The 3,000 pound ATS-F was launched in the spring of 1974 atop a Titan IIIC launch vehicle into a 22,000-mile high synchronous orbit, first above the United States and later above India. ATS spacecraft prime contractor to the GSFC, Greenbelt, Maryland, was Fairchild Industries, Germantown, Maryland. This view is from outside the chamber looking through the huge doorway.
