| I'm not sure Mac, it's a good clip but i always thought if it was ET it was maybe just the movement of a craft. |

Notes on the STS-80 'UFOs' (James Oberg - January 1997) The STS-80 scenes seem to me to be identical in origin to the infamous STS-48 scenes and to numerous others throughout the shuttle flight program: low-light sensitive B&W cameras are trained on the receding horizon during night passes, to observe serendipitous lightning events for an experiment called Mesoscale Lightning Experiment, managed out of NASA-MSFC in Huntsville. You can see the dark horizon, the glowing 'air glow' layer, moving stars, moving city lights below, lightning flashes, and under moonlit conditions, dim clouds. By the way, these low-light B&W cameras are pretty old and are being replaced mission by mission -- the suite of cameras carried by a shuttle (one in each corner of the payload bay, two on the RMS, others perhaps mounted on the keel looking upwards at target spacecraft, plus a few handheld units inside the cabin) can be adjusted as needed, and a new color CCD camera is much higher quality (it doesn't 'bloom' in overbright reflections, and can't be damaged by sun exposure), but it's not as sensitive in low light, so there are fewer opportunities to see such views every year. When sunrise occurs (due to the Orbiter's motion along its orbit), even though the Orbiter is now bathed in sunlight, the camera is still trained on the dark side of Earth. But now the floating particles which routinely accompany every shuttle flight (often ice particles, sometimes junk from the payload bay, pieces of insulation blankets, a dozen or more distinctly different sources) can become visible in the sunlight, sometimes even moving into sunlight from the umbra of the Orbiter (and thus "appearing suddenly"). These are close to the camera, sometimes a few feet, at most a few hundred feet. Sometimes they are hit by pulses of gas from the RCS jets as they automatically fire to gently nudge the spaceship back towards a pre-set orientation. Because of the sensitivity of the camera, moving particles leave streaks -- even stars can be seen to do this when the camera is being panned (usually by command from a controller in the Mission Control Center). Tumbling particles tend to flash. Bright particles overload the optics and appear as "rings" or "do-nuts" with darker centers. There's nothing else to it, as far as I can tell. Everyone in the control center knows about this visual phenomenon, everyone has seen it numerous times, and they laugh at notions these are anomalous, while they grimace at yet more silly stories by people who don't seem to understand much (or do seem to misunderstand a lot) about "ordinary" space flight. As far as I was able to determine, these STS-80 scenes were recorded beginning about 11:55 PM PST on December 1, 1996. That's 07:55 GMT on December 2. Since the shuttle was launched on Nov 19, that is 324/19:55:47, this makes it about 12 days 11 hours 59 minutes "Mission Elapsed Time", or MET. This was on rev 197, crossing Venezuela, then the West Indies. The Orbiter attitude was bottom forward, with the vehicle yawed somewhat so the nose was off to one side. According to the activity plan sent up that morning, the crew was doing some evaluation of an EVA tool associated with their airlock problems, and the two pilots were scheduled to begin a review of landing procedures. Lunch was to follow. When I asked crewman Story Musgrave, who is not shy about talking about anomalies of any kind, he assured me he saw nothing unusual on the flight, at this point or at any other. The camera, "B" located at the rear of the payload bay, was in a pre-set position which was later changed by ground commands. Judging from the star motion at the horizon, it was looking southwest, not precisely backwards (since then the stars would have been setting straight down across the horizon). I don't have the exact numbers on the camera's pan/tilt and it's too much trouble to get them. According to a computer reconstruction of the trajectory, sunrise occurred at GMT 07:57. That's precisely when the picture shows a slight foggy periphery, and when the first objects appear. They keep showing up until about 08:01, when sunlit clouds come into the camer's field of view and the iris automatically stops way down so that the tiny objects (and stars too) are no longer visible. The camera view continues in daylight for long after that. The crew's "Earth Obs Exposures" daily plan listed ground targets which confirm this flight path: 12/11:54:05 Caracas 12/11:55:58 Montserrat and then 12/12:19:34 Lake Nasser 12/12:21:13 Jiddah, Saudi Arabia 12/12:21:23 Mecca These are "opportunities" only, not assignments, and apparently nobody was free to take the shots over Caracas and Montserrat. Here is some trajectory data from which you can reconstruct the flight path and lighting conditions at the interval of interest, if you have the commonly- available software. M50 State Vector GMT 337:00:54:47.00 MET 012:04:59:00 Position (ft) X 7272023.0 Y -20753260.5 Z -2137127.9 Velocity (ft/sec) VX 20614.669694 VY 8420.434295 VZ -11894.207423 At MET 12/11:55:47 for example, position is lat 15.07N, Lon 62.06W, alt 185.4nm, inertial velocity 25245.6034 ft/sec, the orbital range is 183.8361 to 193.8737 nm, period 91:23.435, beta angle -34 degrees (the sun is off to the right of the orbital plane by this angle), The video that I saw over in the Public Affairs Office was tape #612710. If you want to specify it to buy your own copies, give the MET or GMT times, and order ten minutes before and after the interval, so you can see the typical phenomena of stars leaving trails, and auto iris control functioning, and at one point the constellation Orion going by, and at the end a view around the Orbiter's sunlit payload bay. All very ordinary, unspectacular, normal space views, in my opinion. I don't know where the impression came from that this was a rebroadcast of daily highlights, since these programs are invariably short (10-15 minutes), with short clips jumping from scene to scene, usually involving views of astronauts. This sequence, on the other hand, was continuous for at least 20 minutes from the same camera, and the geography and lighting are consistent with the real time orbital motion. I looked at the "Flight Day Highlights" summary for three days around this date and that's what they consisted of, with no replay of any of these "dancing dots" scenes (why should there have been?). I don't expect that this will change many minds and I don't intend to go on television to face some wild accusations that I'm a paid liar for the grand conspiracy, and basically I don't take anyone seriously who takes these stories seriously. Life's too short for me to care what some people want to believe these scenes show. I've already spent too much time, but I figured somebody had to make a rational response, whether it was understood and believed, or not. ___________ |
