Picture of the Day: The Thin Blue Line of Earth's Atmosphere


Taken by the STS-133 crew, there's a lot going on in this photograph. On the right, you can see a docked Russian Soyuz spacecraft, one of the space giants designed by the Korolyov Design Bureau back in the 1960s for the Soviet space program. The Soyuz is a series that has been used now for more than 45 yeas. On the left, a small portion of the International Space Station's Quest airlock and some solar array panels. The Soyuz docks to the ISS for up to six months at a time. The most interesting component of the photograph, though, might be the thin blue line of Earth's atmosphere seen in the distance as surrounded by the pitch blackness of space.
