UARS still in space – Just seen from Texas

September 24, 2011 | By | Add a Comment

An observer living in Clear Lake, Texas (United States) has just reported seeing NASA’s Upper Atmosphere Research Satellite. That is encouraging in that it is still ‘up there’ and not going to re-enter over the United States. Other (U.S.) observers are also reporting that they have seen it. It is also flashing – which is […]

Increased probability that NASA UARS satellite debris could land in United States

September 24, 2011 | By | Add a Comment

While the probability is small, it looks like there is the possibility that debris from NASA’s Upper Atmosphere Research Satellite (UARS) could crash to Earth back at its point of origin, the United States. If not there, then another populated part of the Earth’s surface is possible (again a very low probability given how much […]

When to look for NASA’s out of control satellite

September 22, 2011 | By | Add a Comment

At this stage, no one is exactly sure to look for NASA’s out of control Upper Atmosphere Research Satellite. Unfortunately the satellite will not be making any more evening passes over Australia before it is expected to be destroyed reentering the Earth’s atmosphere Saturday morning Australian Time. The next best thing that we […]

Upper Atmosphere Research Satellite de-orbit time firms up

September 21, 2011 | By | Add a Comment

The re-entry of NASA’s Upper Atmosphere Research Satellite (UARS) is rapidly drawing closer. NASA still has to issue an official de-orbit time. That is understandable given that the satellite is out of fuel, and therefore out of control. At the time of writing this, the NASA website states that re-entry is expected to be around […]

UARS re-entry draws closer

September 17, 2011 | By | Add a Comment

Since I made my last post about the re-entry of NASA’s Upper Atmosphere Research Satellite (UARS), it’s orbit has decreased even further. In the last approximately 36 hours NASA has changed the re-entry forecast twice. Unfortunately the rapid change in its orbit means that visibility predictions for this satellite are now unreliable. We now have to wait […]

Increased solar activity brings re-entry of UARS NASA satellite closer

September 16, 2011 | By | 2 Comments

Update (8.34 am AEST): I have just checked the visibilty updates for Australia for viewing the UARS satellite in our evening sky. Unfortunately the significant change in the satellites orbit due to solar heating of the upper atmosphere means these no longer exist. We now have to wait for updates from NASA regarding […]
