Now your link is click-able, and the video has a name. I think the astronaut is seeing gas escaping from one of the tanks on the ship. We have seen this before on the Moon missions where liquid oxygen escapes into the vacuum of space and it looks like glowing crystals through the window of the craft. John. |

thx for fixn my link...much appriciated ...would gaseous dishcharge show in IR video though? if so in IR, gasses would not be heat beacons in vacuum id think it should be grayed out, yet still heat points visible? mildly curious if not anything else ... :) |

electric glow dishcharge perhaps? |

John, I watched some documentary about the moon missions and they showed film footage of a liquid oxygen leak that happened outside the window of the orbiter. In the film footage, you can see Neil Armstrong and Buzz Aldern looking out the window at these funny sparkling crystal looking things flying away from the orbiter. And they looked at their gauges and saw the liquid oxygen level had dropped. They knew it was a leak! Now its not that liquid oxygen in a vacuum would give off infra red light. Its more that it seemed to sparkle by diffracting other light near by. But little crystals did look just like loads of little UFO's outside the window of the craft. In space, its hard to judge distance so a near-by sparkling crystal could look like a distant UFO if you can't judge the distance to the object. Maybe search Youtube and you might find a video about it. Try search words like "Liquid oxygen leak Apollo moon mission", or something like that. Johnney. |

It was apollo 13 that had the oxygen leak. Here are 2 videos about it; Houston, We Have A Problem http://www.youtube.com/watch?v=hE6NoPjWCLo Situation Critical: Apollo 13 http://www.youtube.com/watch?v=vuE0ZcDo-EM NASA has actual real footage of the event, but i can't find it. John. |

"Now its not that liquid oxygen in a vacuum would give off infra red light." seeing this video in IR surfaces the question? is it heatless liquid O2 leaking? in Infra Red? would that even be visible on said spectrum? carrying my curiousity.... |

John, The reason i wanted to show you the oxygen leak videos from Apollo 13 is that you can actually see "stuff" flying around outside the window of the craft. And it looks really unusual to see this "stuff" flying around outside the window of the Apollo craft. More importantly, the leaked liquid oxygen floating around looks like hundreads of little UFO's! So yes, liquid oxygen in space can look like UFO's! And the original video you posted is NOT infra red. Its just a normal black and white camera, despite what the guy in the video might tell you. You might think that if you look out the window of the international space station or any spacecraft, you would expect to just see empty space. But this is far from the truth. In near earth orbit, where the ISS is, there is tonnes of stuff flying around all over the place. And in near earth orbit, all that "stuff" will get ionised and could well glow in either visible light or infra red. But at the same time John, its good to be open minded. There is a small possibility that it could be an alien spacecraft. We can't rule it out completely. Johnney. |
