Space Radar Reveals Topography of Tsunami Site

Two color-coded perspective views of the Independent State of Samoa (left) and American Samoa (right), generated with digital elevation data from the Shuttle Radar Topography Mission, illustrate the varying topography of the islands. A tsunami generated by a major undersea earthquake on Sept. 29, 2009, inundated the more heavily populated southern coast of Tutuila, the largest of the islands of

Training and Shuttle Preps Highlight the Day

Technicians at NASA's Kennedy Space Center in Florida have completed Atlantis' crew module final prep work and side hatch closure in anticipation of the vehicle's rollover from Orbiter Processing Facility-1 to the Vehicle Assembly Building, scheduled for Oct. 6.Atlantis will be lowered on its wheels today and then weighed. A center-of-gravity check will be performed to make sure the shuttle is

Astro Mike Rockets to a Million on Twitter

In tweet-speak, it might have been called a “twace,” the great space race on Twitter.Astronaut Mike Massimino became the first human to tweet from space on his final trip to repair the Hubble telescope. It was no contest, however, that he recently also became the first astronaut to reach one million followers on Twitter.And who says, “In space, no one can hear you tweet?”On April 1, 2009, it was

Radial Channels Carved by Dry Ice

Spider-shaped features in the south polar region of Mars are carved by vaporizing dry ice in a dynamic seasonal process. This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter includes several of the distinctive features in an area 1.2 kilometers (three-fourths of a mile) wide. It is one of the HiRISE camera team's featured images this

NASA Goddard Shoots the Moon to Track LRO

On certain nights, an arresting green line pierces the sky above NASA's Goddard Space Flight Center in Greenbelt, Md. It's a laser directed at the moon, visible when the air is humid. No, we're not repelling an invasion. Instead, we're tracking our own spacecraft.28 times per second, engineers at NASA Goddard fire a laser that travels about 250,000 miles to hit the minivan-sized Lunar
