Each of the two solar cell arrays on the space station that will be deployed in orbit, is designed to provide 10,500 watts of power at 55 degrees centigrade while in the sunlight portion of each orbit. All power needed to operate the station and the Apollo Telescope mount will be taken from the arrays. The remainder of the power generated will be diverted to battery chargers which will keep the batteries at full charge and ready for use while the orbiting spacecraft cluster is in the Earth's shadow. Each array will have almost 1,177 square feet of surface area to turn sunlight into electrical power. Skylab 1 is schedule for launch April 30, 1973 and Skylab 2, carrying the astronauts Conrad, Kerwin and Weitz to dock with the space station and enter it to live and work for 28 days, will be launched a day later.
