Space shuttle Discovery, returning to Earth Wednesday from its last mission, is expected to land in Florida just before noon Eastern Standard Time. Mission managers laud a nearly flawless flight.
The space shuttle Discovery left the International Space Station behind having done everything it was scheduled to do and more. It is set to land Wednesday.
Post-Columbia inspection methods show that foam seen tumbling along Discovery's tiles – and apparently hitting twice – caused only cosmetic damage, say NASA engineers.
After a photogenic lift-off, the space shuttle Discovery and its crew headed toward the International Space Station. The crew will inspect the orbiter's tiles after some insulating foam fell late in the ascent.
For 30 years, the space shuttle launch has served as the centerpiece of the US space program. But Feb. 24 will mark the last shuttle launch of Discovery, with the final flight of Endeavour to follow in April and – if there's enough money – Atlantis's last flight of the entire program in June. Here are five questions about what the shuttles have – and haven't – accomplished.
Mars’ northern-most sand dunes are seen as they begin to emerge from their winter cover of seasonal carbon dioxide (dry) ice in this image acquired by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter Jan. 16, 2014. The steeply sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune. Dark splotches are places where ice cracked earlier in spring, releasing sand.

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.
Billows of smoke and steam infused with the fiery light from space shuttle Endeavour's launch on the STS-127 mission fill NASA Kennedy Space Center's Launch Pad 39A on July 15, 2009.
Trailing a thick column of exhaust, the Space Shuttle Columbia blasted into the twilight morning sky in 2002, its thundering rockets briefly flooding a cloud bank with the light of a false dawn. The event marked the start of the ongoing eleven day mission to upgrade the Hubble Space Telescope. The shuttle would later be burned up on re-entry in a tragic 2003 accident, killing all seven of its crew.
