About this work
The Apollo Telescope Mount (ATM) was designed and developed by the Marshall Space Flight Center and served as the primary scientific instrument unit aboard Skylab (1973-1979). This photograph shows the spar unit, which housed major solar instruments, being lowered into the rack, the outer octagonal complex frame of the ATM flight unit.
