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 February 9, 2010 during the STS-130 mission.
A quarter moon is visible in this oblique view of Earth's horizon and airglow, recorded with a digital still camera on the final mission of the Space Shuttle Columbia. Columbia's crew was killed on Feb. 1, 2003 when the shuttle broke up on re-entry into Earth's atmosphere.
Apollo 8 served as the first manned lunar orbit mission, and the first manned flight of the Marshall Space Flight Center (MSFC) developed Saturn V launch vehicle. Lift off occurred on December 21, 1968. This photograph of Earth above the lunar horizon is one of many taken by the crew. All systems operated within allowable parameters and all objectives of the mission were achieved.
Among the first group of still images downlinked by the STS-125 crew members aboard the space shuttle Atlantis was this high oblique scene looking toward the Sinai Peninsula and the Mediterranean Sea. The Red Sea is just out of frame at bottom right. Saudi Arabia is in the right foreground and Egypt's Nile River and its delta can be seen (lower left) toward the horizon. Jordan and a small portion of Israel can be seen near the top of the frame.
The Space Shuttle Endeavour's robotic arm hovers over Earth's horizon, backdropped by a starburst from the Sun. This photo was taken during the STS-77 shuttle mission in 1996.
The setting sun and the thin blue airglow line at Earth's horizon was captured by the International Space Station's (ISS) Expedition Three crewmembers with a digital camera. Some of the Station's components are silhouetted in the foreground.
As photographed through a hatch window on the Space Shuttle Discovery, Russia's Mir space station is backdropped against Earth's horizon. The photo was made during the final fly-around of the members of the fleet of NASA shuttles.
This NASA image released June 21, 2010 shows the Aurora Australis Observed from the International Space Station on May 29, 2010. This aurora image is taken during a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun.
The solar panel supporting the Zvezda Service Module on the International Space Station is backdropped against Earth's horizon at dawn. The image was made by one of the Expedition Two crew members using a digital still camera.
The STS-68 crew aboard the Space Shuttle Endeavour told a post-flight audience at JSC that this sunrise was one of the most scenic sunrises/sunsets witnessed during the week and a half long Space Radar Laboratory (SRL-2) mission. Jutting clouds, back-lit by the dawn colors, are sandwiched between the blue airglow and the silhouetted horizon of Earth.

Scotland will vote in 2014 whether to split off from England and the rest of the United Kingdom. Scottish nationalists argue that Scotland would be better off alone.
Ending Britain's 306-year rule would allow Scotland to reverse generations of economic mismanagement and free its lawmakers to boost economic growth, say Scottish nationalists campaigning to split from the UK.
