NASA-UAP-D007：天空实验室技术任务报告（1973年）

Launched on May 14, 1973, Skylab was the United States’ first laboratory in space. From 1973 to 1974, the station was visited by three crews. This document contains excerpts from all three crews to visit the station. In the first excerpt taken from Skylab 1/2 [first crew] Technical Debriefing from June 30, 1973, highlights crew observations of light flashes. The second excerpt taken from Skylab 1/3 Technical Crew Debriefing from October 4, 1973, highlights two observations—a satellite in similar orbit and another object with a “reddish hue to it.” The final excerpt taken from the Skylab 1/4 Technical Crew Debriefing from February 22, 1974, highlights an observation of flashing lights outside Skylab. • Skylab 2 crew observation: o Page 23-20. [Science Pilot for Skylab 2, Joesph Kerwin] “We saw light flashes. I think all of us saw them. I saw them most often when I was in the sack at night with my eyes closed but awake naturally. They tended to wax and wane in frequency.” • Skylab 3 crew observations: o Page 7-4. [Science Pilot for Skylab 3, Owen Garriott] “We saw that satellite about a week before splashdown. That was one of the most unusual things that we saw and I guess Jack [Lousma] noticed it looking out the window. This bright reddish object was out there and we tracked it for about 5 or 10 minutes. It was obviously a satellite in a very similar orbit to our own.” o Page 20-1. [Science Pilot for Skylab 3, Owen Garriott] “Jack [Lousma] first noticed this rather large red star out the wardroom window. Upon close examination, it was much brighter than Jupiter or any of the other planets. It had a reddish hue to it, even though it was well above the horizon.” • Skylab 4 crew observation o Page 7-8. [Commander for Skylab 4, Gerald P. Carr] “One other area of unusual events that we reported on the dump tapes was that on occasion we saw some lights flashing outside with very a definite motion relative to ours. We presumed that they were other pieces of Skylab, or possibly other satellites.”
