Shuttle Mission STS-48

On September 15, 1991, live video showing multiple objects moving in unusual trajectories was captured by cameras aboard the Space Shuttle Discovery (STS-48).

Starting about 1 minute 38 seconds into the video pay attention to the upper right quadrant.

The video, which was being broadcast over NASA Select TV, was recorded by Mr. Donald Ratsch. Mr. Ratsch observed what he believed to be four anomalous events. One of those events was recorded by a camera in the shuttle's payload bay between 20:30 and 20:45 GMT (starting about 1 minute 38 seconds into the video) near the west coast of Australia. The event involves perhaps as many as a dozen objects moving in different directions relative to the spacecraft. One of the objects appears at a point near the horizon and moves in a path that seems to follow the horizon. After a flash, the object abruptly changes direction and speed. This is followed a few seconds later by a streak that moves rapidly across the field of view and crosses the path of the object. At the end of the event, the camera pitches down to reveal several objects moving below the shuttle. One of the objects has a triangular shape.

STS-48 was a Space Shuttle mission that launched on 12 September 1991, from Kennedy Space Center, Florida. The orbiter was Space Shuttle Discovery. The primary payload was the Upper Atmosphere Research Satellite. The mission landed on 18 September at 12:38 am at Edwards Air Force Base on runway 22. The mission was completed in 81 revolutions of the Earth and traveled 2.2 million miles. The 5 astronauts carried out a number of experiments and deployed several satellites. The total launch mass was 240,062 pounds (108,890 kg) and the landing mass was 192,780 pounds (87,440 kg).
