Shuttle Silhouette (Credit: NASA)

“In a very unique setting over Earth’s colorful horizon, the silhouette of the space shuttle Endeavour is featured in this photo by an Expedition 22 crew member on board the International Space Station, as the shuttle approached for its docking on Feb. 9 during the STS-130 mission.”

“The orbital outpost was at 46.9 south latitude and 80.5 west longitude, over the South Pacific Ocean off the coast of southern Chile with an altitude of 183 nautical miles when the image was recorded. The orange layer is the troposphere, where all of the weather and clouds which we typically watch and experience are generated and contained. This orange layer gives way to the whitish Stratosphere and then into the Mesosphere. In some frames the black color is part of a window frame rather than the blackness of space.”
