... Astronauts and cosmonauts should be prepared for this possibility before their launch and accurately trained to face the possibility that their craft or the space station where they work can be approached by anomalous aerial phenomena. Reports of videos of "spheres of light" are not uncommon from space and some scientific analysis already exists (Carlotto, 1995;Kasher, 1995). An accurate scientific study of these data from space can permit us to ascertain if such anomalies are of plasma, technological, meteoric, cometary, or of a more prosaic nature. ...

Spherical unidentified anomalous phenomena (UAP), of both plasma and solid-like kinds, have often been observed in the world. Several monitoring campaigns have permitted us to know better some structural properties and temporal behaviour of such phenomena. On the basis of what has been observed so far, and considering the deduced constants that characterize the phenomenon, and of the consequent physical working-hypotheses that results, possible dangers to aviation are examined from several point of view of physical science; both natural and non-natural features of these kind of UAP are considered. A systematic instrumented observational plan is proposed, involving both recurrence areas and time flaps of the phenomenon itself.

... Jack Kasher produced five proofs that the objects seen in the video could not be ice particles disturbed by a thruster firing 3 . Carlotto found that instead of following linear paths, a number of the objects travel in circular arcs, which implies the objects were far from the shuttle and moving at a high rate of speed 4 . The estimated speed of one of these objects, about 35 km/sec, is approximately the same as that of a "fastwalker" tracked by the North American Air Defense Command in 1984 5 . ...

Analysis of video from Space Shuttle mission STS-80 provides new insight into a number of unusual events captured by a camera aboard the space shuttle Columbia in 1996. Three different phenomena are analyzed: 1) two slow moving circular objects, 2) a number of fast moving objects in space near the shuttle, and 3) a strange luminous apparition near the earth's surface. The two slow moving circular objects have attracted a great deal of popular interest due to their disk-like shape. One seems to appear out of a cloud layer, the other moves into the camera's field of view. It is argued that both are likely to be pieces of shuttle debris emerging from the spacecraft's shadow. The fast moving objects in space near the shuttle appear as bright streaks moving rapidly across the video frame. Analysis of their speeds and directions implies that they are not shuttle debris or meteors. Perhaps the most interesting observation is a rapidly moving burst of light that appears near the earth's surface off the east coast of Puerto Rico. Occurring well before sunrise, away from thunderstorm activity, and moving at an estimated speed of over 500 miles/sec., this is one of the most unusual phenomena observed to date by the shuttle. Its similarity to certain ground-based sightings suggests that it might represent the first observation of a new kind of atmospheric phenomenon from space.
