S127-E-008368 (24 July 2009) --- While astronauts Tom Marshburn and Christopher Cassidy (both out of frame), made their spacewalk on July 24, the two mission specialists and the crews of STS-127 and the International Space Station's Expedition 20, were able to enjoy scenes such as this one of one of the orbital outpost's solar panels intersecting Earth's horizon. Eleven astronauts and cosmonauts remained inside the International Space Station and the shuttle to which it was docked, while the two suited astronauts continued work on the orbital outpost.
