space shuttle atlantis sts 122 progress



Space Shuttle Atlantis STS-122, Progress-M62 flaring, and the ISS

After a sunny day, but with cirrus in the sky, the evening of February

8 was clear. This was the only evening that I had a chance to observe

the Space Shuttle Atlantis STS-122 before it docks to the

International Space Station. The sequence was for ISS to make a

near-zenith pass in twilight around 18:55 local time, followed by

Progress-M62 on a similar trajectory ten minutes later, and finally

the Space Shuttle STS-122 a quarter of an hour after that, entering

shadow just below the zenith.

First the ISS passed, reaching magnitude -3 in the zenith:

Next the Progress-M62 spacecraft leaving ISS filled with garbage made

a pass. It spectacularly flared to mag. -2 in Andromeda (in the image

below, M31 the Andromeda galaxy is just to the right of the trail),

while the camera was open. The result is this very nice image:

In this second image, it is back to it's normal brightness of mag. +1

again:

15 minutes later the Space Shuttle Atlantis STS-122 on its way to the

ISS passed, reaching mag. -1 before going into eclips just below the

zenith:

A fine evening altogether! And although I have seen Space Shuttles

pass before, this is the first time I catched one on photograph. The

spectacular flare of Progress-M62 really made the evening though.
