This image from NASA's Terra satellite covers an area of 34 by 25 miles over the southwest part of the Malaspina Glacier and Icy Bay in Alaska. The composite of infrared and visible bands results in the snow and ice appearing light blue, dense vegetation is yellow-orange and green, and less vegetated, gravelly areas are in orange. The Malaspina Glacier is currently thinning. Its terminal moraine protects it from contact with the open ocean; without the moraine, or if sea level rises sufficiently to reconnect the glacier with the ocean, the glacier would start calving and retreat significantly.
An open letter to Congress signed by 24 former NASA astronauts told Congress that privately owned spacecraft could carry people safely to the International Space Station.
Astronaut Stephen K. Robinson, STS-114 mission specialist, anchored to a foot restraint on the International Space Station's Canadarm2, participates in the mission's third session of extravehicular activity on August 3, 2005.
A setting sun and Earth's horizon are featured in this image photographed by an Expedition 13 crewmember on the International Space Station in 2006.
In this image of the Andes along the Chile-Bolivia border, the visible and infrared data have been computer enhanced to exaggerate the color differences of the different materials. The scene is dominated by the Pampa Luxsar lava complex, occupying the upper right two-thirds of the scene. Lava flows are distributed around remnants of large dissected cones, the largest of which is Cerro Luxsar.
Like a sun on a fast rise, Space Shuttle Atlantis arcs into the still-black sky over the Atlantic Ocean, casting a fiery glow on its way. With a crew of five it is heading on the 10th assembly flight to the International Space Station. The primary payload on the mission is the joint airlock module, which will require two spacewalks to attach it to the Space Station. The airlock will be the primary path for Space Station spacewalk entry and departure for US spacesuits, and will also support the Russian Orlan spacesuit for EVA activity.
This image shows average temperatures in April, 2003, observed by AIRS at an infrared wavelength that senses either the Earth's surface or any intervening cloud. Similar to a photograph of the planet taken with the camera shutter held open for a month, stationary features are captured while those obscured by moving clouds are blurred. Many continental features stand out boldly, such as our planet's vast deserts, and India, now at the end of its long, clear dry season.
If you've got an adventurous spirit and a fat bank balance, these out-of-this-world holidays are for you.
An unmanned Russian ship loaded with nearly 2.5 tons of fresh food, clothes, and equipment has gone rogue, blowing past the International Space Station.
This image courtesy of the European Southern Observatory (ESO) shows an artist's impression of an active galaxy that has jets. The central engine is thought to be a supermassive black hole surrounded by an accretion disc and enshrouded in a thick doughnut-shaped structure of gas and dust, which astronomers call a "torus". The torus of dust and gas can be seen orbiting a flatter disc of swirling gas. In the center, the supermassive black hole is surrounded by a flat accretion disc of rapidly orbiting material. The jets are emitted at right angles from the plane of the disc.
