This week in 1984, space shuttle Challenger, mission STS-41G, landed at NASA’s Kennedy Space Center following a successful eight-day mission. The mission’s main objective was to deliver the Earth Radiation Satellite to orbit. Components of the Orbital Refueling System were connected, demonstrating it is possible to refuel satellites in orbit. STS-41G was the first flight to include two female astronauts, Sally Ride and Kathryn Sullivan. Here, Sullivan checks the latch of the Shuttle Imaging Radar-B antenna in the Challenger’s cargo bay as she became the first American woman to walk in space Oct. 11, 1984.
