This is one of four Solar Array panels from the planned second Apollo Telescope Mount (ATM). The ATM was the major scientific instrument aboard Skylab, which was put into earth orbit in May 1973 and operated for 8 months. ATM included eight major scientific instruments as well as a number of smaller experiments, and was designed to be operated by three sets of visiting astronauts. The solar array provided the electrical power to operate the scientific instruments carried on the ATM.
The array was transferred from NASA's Marshall Space Flight Center in 1989.
