Anchored to the Canadarm2 mobile foot restraint, Garrett Reisman performed construction and maintenance activities outside the station during the STS-132 mission's first spacewalk. During the seven-hour, 25-minute spacewalk, Reisman and NASA astronaut Steve Bowen installed a second antenna for high-speed Ku-band transmissions and added a spare parts platform to Dextre, a two-armed extension for the station’s robotic arm.

NASA's Mars Exploration Rover Project will pass a historic Martian longevity record on Thursday, May 20.

The United States Distance Learning Association recognized NASA's Digital Learning Network (DLN) for its superior instructors by presenting the program with the Silver Award for Distance Learning Teaching.

NASA astronaut Garrett Reisman takes a self-portrait visor while participating in the first of three spacewalks scheduled for the Atlantis crew and their Expedition 23 hosts. Though three spacewalks will involve only three astronauts (two on each occasion) who actually leave the shirt-sleave environments of the two docked spacecraft, all twelve astronauts and cosmonauts have roles in supporting the work. Part of the space station and the blue and white Earth are among the objects seen in his visor. Fellow spacewalker Steve Bowen, mission specialist, is out of frame. Image Credit: NASA

Space shuttle Atlantis and the International Space Station are flying together 220 miles overhead until Sunday, May 23. Circling the Earth every 90 minutes, the spacecraft offer unique sighting opportunities for sky gazers around the world.

NASA selected 17 technology demonstration projects for reduced-gravity aircraft flights to demonstrate whether emerging technologies can perform as expected in the reduced-gravity environment of the moon and Mars, or the zero-gravity environment of Earth orbit.

NASA's space shuttle Atlantis is delivering science experiments and a new Russian laboratory to the International Space Station, continuing the transition from station assembly to continuous scientific research through the end of the decade.

NASA will hold a media teleconference Friday, May 21, at 3:15 p.m. EDT with the crew of the NASA Extreme Environment Mission Operations, or NEEMO, living underwater off the coast of Florida.

Space shuttle Atlantis soars to orbit from Launch Pad 39A at NASA's Kennedy Space Center in Florida on the STS-132 mission to the International Space Station at 2:20 p.m. EDT on May 14.

Space shuttle Atlantis lifted off from Launch Pad 39A at NASA's Kennedy Space Center in Florida on the STS-132 mission to the International Space Station at 2:20 p.m. EDT on May 14. The third of five shuttle missions planned for 2010, this was the last planned launch for Atlantis. The Russian-built Mini Research Module-1, also known as Rassvet, or "dawn," will be delivered and it will provide additional storage space and a new docking port for Russian Soyuz and Progress spacecraft. The laboratory will be attached to the bottom port of the station's Zarya module. The mission's three spacewalks will focus on storing spare components outside the station, including six batteries, a communications antenna and parts for the Canadian Dextre robotic arm.

One of the final space shuttle visits to the International Space Station began at 2:20 p.m. Friday with the launch of Atlantis and six astronauts from NASA's Kennedy Space Center in Florida.

A family of Osprey are seen outside the NASA Kennedy Space Center Vehicle Assembly Building in Cape Canaveral, Fla. on Thursday, May 13, 2010. The Merritt Island National Wildlife Refuge overlaps Kennedy and provides a habitat for 330 species of birds, including the osprey. A variety of other wildlife--117 kinds of fish, 65 types of amphibians and reptiles, 31 different mammals, and 1,045 species of plants--also inhabit the refuge. The countdown is on for today's scheduled launch of space shuttle Atlantis on its STS-132 mission. At NASA's Kennedy Space Center in Florida, technicians at Launch Pad 39A continue preparations for the liftoff at 2:20 p.m. EDT. Image Credit: NASA/Bill Ingalls

A heavy runaway star is rushing away from a nearby stellar nursery at more than 250,000 miles an hour, a speed at which one could travel to the our moon and back in two hours. This is the most extreme case of a very massive star that has been kicked out of its home by a group of even heftier siblings. The homeless star is on the outskirts of the 30 Doradus Nebula, a raucous stellar breeding ground in the nearby Large Magellanic Cloud. The stellar nusery is seen at the center of this image. The finding bolsters evidence that the most massive stars in the local universe reside in 30 Doradus, making it a unique laboratory for studying heavyweight stars. Also called the Tarantula Nebula, 30 Doradus is roughly 170,000 light-years from Earth. Tantalizing clues from three observatories, including the Hubble Space Telescope's newly installed Cosmic Origins Spectrograph (COS), and some old- fashioned detective work, suggest that the star may have traveled about 375 light-years from its suspected home, a giant star cluster called R136. Nestled in the core of 30 Doradus, R136 contains several stars topping 100 solar masses each. Visit Hubble Catches Heavyweight Runaway Star for more information. Image Credit: NASA, ESA, C.
