STS-51A satellites in shuttle cargo bay

51A-41-058 (12 November 1984) --- Astronaut Joseph P. Allen IV appears to be lifting weights. Astronaut Dale A. Gardner holding on. Actually, Dr. Allen is the sole anchor for the top portion (and most of) the captured Palapa B-2 communications satellite during the Nov. 12 retrieval extravehicular activity (EVA) of the two mission specialists. This scene came near the end of the long-duration task. Gardner used a torque wrench to tighten clamps on an adapter used to secure the Palapa to its "parking place" in Discovery's cargo bay. Note the difference between the two stinger devices stowed on Challenger's port side (right side of frame). The one nearer the spacecraft's vertical stabilizer is spent, having been inserted by Allen earlier in the day to stabilize the communications satellite. The one nearer the camera awaited duty in two days when it would aid in the capture of the Westar VI satellite.
