Mark J. CARLOTTODigital Video Analysis Of Anomalous Space Objects 45-63
Abstract: Video data showing multiple objects moving in unusual trajectories in space is examined. The video was captured by a camera aboard the Space Shuttle Discovery (mission STS-48) between 20:30 and 20:45 GMT on 15 September 1991 near the west coast of Australia. Digital video analysis is performed to determine if the objects in question are ice particles disturbed by a thruster firing as contended by NASA or other objects moving independently of the shuttle. Results of our analysis show that it is unlikely that a thruster firing occurred since the attitude of the spacecraft does not change. Our analysis indicates that there are two groups of correlated object motions. One group changes direction at the time of a flash, claimed by NASA to be due to a thruster firing. The other group changes direction 1.5 seconds later. Assuming the objects are roughly the same size, brightness measurements of the objects as they pass over the airglow layer near the limb suggest that the objects in the first group are farther away yet they change direction first. This behavior is inconsistent with the thruster firing hypothesis. For one of the objects known as the "target", it is shown that the only hypothesis that is consistent with the data is that the object is at or near the physical horizon. We go on to show that several other objects in the video are clearly moving in circular arcs and are thus likely to be relatively far away from the shuttle. The estimated speed of one of these objects, about 35 kmlsec, is approximately the same as that of the target if we assume that it is at the physical horizon. At the end of the event, the shuttle's camera pans down to reveal a number of objects moving below the shuttle. One of the objects appears to have a definite structure consisting of three lobes arranged in a triangular pattern
