Well, while here in Cologne, Germany (I am here to visit the European Space Agency), I was informed that due to increased solar activity, the UARS Satellite (it's the NASA Upper Atmosphere Research Satellite) is excepted to fall back on Earth even sooner than anticipated. It currently is expected to come down between September 22 and 24, 2011.
Now why is that? As solar activity increases, extreme ultraviolet radiation (also called EUV) heats Earth's gaseous envelope, causing it to "swell" and reach father into space than normal. The puffed-up atmosphere causes the slow-down of orbiting spacecrafts because of this additional "drag".
From September 5 to 8th the "badboy" Sunspot 1283 produced several big solar flares and coronal mass ejections; Two X-class flares (the biggest category) and two M-class flares (the middle category, but still plenty powerful). The last two days we have seen over 25 C-class flares. Watch some of those flares below:
September 6, 2011 - M5-class solar flare
September 6, 2011 - X2-class solar flare
September 7, 2011 - X1-class solar flare
So that is enough to cause the "swelling" of the atmosphere and cause the slow-down of this bus-sized satellite. Most of it will burn up during re-entry. But there is a chance some pieces will survive. Where will they land? There is no way of telling until the satellite is pretty much going through the atmosphere. So, stay tuned.
Oh, and this is as good of a time to put on your fashionable tin-foil hats. Make a statement!
