Launch and in-orbit footage from the mission (including Sullivan and Leestma's EVA) appeared in the 1985 IMAX movie The Dream is Alive.They included commander Robert L. Crippen, making his fourth Shuttle flight and second in six months (Crippen became the first American astronaut to complete two space missions in the same calendar year); pilot Jon A. McBride; three mission specialists – David C. Leestma, Sally K. Ride and Kathryn D. Sullivan – and two payload specialists, Paul D. Scully-Power and Marc Garneau, the first Canadian citizen to serve as a Shuttle crew member, as well as the first Canadian in space.It operated throughout the flight, but problems were encountered with Challenger's Ku-band antenna, and therefore much of the data had to be recorded on board the orbiter rather than transmitted to Earth in real-time as was originally planned.[5] Garneau conducted a series of experiments sponsored by the Canadian government, called CANEX, which were related to medical, atmospheric, climatic, materials and robotic science.The engine fired multiple times to adjust altitude and velocity, including bringing the capsule into and out of a Distant Retrograde Orbit around the Moon.
