This week in 1984, the space shuttle Challenger, mission STS-41G, launched from NASA’s Kennedy Space Center to deliver the Earth Radiation Budget Satellite to orbit. Components of the ORS — Orbital Refueling System — were connected, demonstrating it is possible to refuel satellites in orbit. This was the first flight to include two female astronauts, Sally Ride and Kathryn Sullivan. Here, astronauts David Leestma, left, and Sullivan work at the ORS in the aft end of the cargo bay. This was the first time an American woman walked in space.
