STS-41G crew film
The October 1984 flight of space shuttle Challenger featured a diverse set of accomplishments. The Earth Radiation Budget Satellite environmental spacecraft was deployed and a planet-mapping radar was tested. The seven-person crew was led by Bob Crippen and included the first Canadian in space, Marc Garneau, and the first time two women, Sally Ride and Kathryn Sullivan, had flown aboard one flight. Sullivan and Dave Leestma also conducted a spacewalk to demonstrate techniques for refueling satellites. The crew narrates this post-flight film of STS-41G.
