 This gimbal rig, formally known as the MASTIF, or Multiple Axis
Space Test Inertia Facility, was engineered to simulate the tumbling
and rolling motions of a space capsule and train the Mercury astronauts
to control roll, pitch and yaw by activating nitrogen jets, used as
brakes and bring the vehicle back into control. Image Credit: NASA

 NASA astronaut TJ Creamer talks about his experience in space during a
"Tweetup" at NASA Headquarters, Thursday, July 29, 2010, in Washington.
Creamer, who spent 161 days living aboard the International Space
Station as part of the Expedition 22/23 crew, set up the orbiting
outpost's
live Internet connection and posted updates about the mission to his
Twitter account, sending the first live tweet from orbit. Image Credit:

 Perfectly circular, powerful Hurricane Celia spaned hundreds of miles
over the Pacific Ocean in this image from June 24, 2010. Rough-textured
clouds surround the storm’s distinct eye. Farther from the center of
the storm, spiral arms appear thinner and smoother. The Moderate
Resolution
Imaging Spectroradiometer, or MODIS, on NASA’s Aqua satellite captured
this true-color image of Hurricane Celia at 1:55 p.m. Pacific Daylight
Time on June 24, 2010. Just five minutes later, the U.S. Nationa... Continue reading...

 Recently, technicians at NASA's Marshall Space Flight Center in
Huntsville, Ala., completed a series of cryogenic tests on six James
Webb Space Telescope beryllium mirror segments at the center's X-ray
& Cryogenic Facility. During testing, the mirrors were subjected to
extreme
temperatures dipping to -415 degrees Fahrenheit, permitting engineers
to measure in extreme detail how the shape of the mirror changes as it
cools. The Webb telescope has 18 mirrors, each of which will be tested
twice i... Continue reading...

 On Jan. 2, 2004 NASA's Stardust spacecraft made a close flyby of comet
Wild 2 (pronounced "Vilt-2"). Among the equipment the spacecraft
carried on board was a navigation camera.that Comet Wild 2 is about 3.1
miles in diameter. This artist's concept depicts a view of Wild 2
that shows the faint jets emanating from the comet. Image Credit:

 The Orion Nebula is a 'happening' place where stars are born and this
colony of hot, young stars is stirring up the cosmic scene in this
image from NASA's Spitzer Space Telescope. The young stars dip and peak
in brightness; shifting cold and hot spots on the stars' surfaces cause
brightness levels to change. In addition, surrounding disks of lumpy
planet-forming material can obstruct starlight. Spitzer is keeping tabs
on the young stars, providing data on their changing ways. The hottest
star... Continue reading...

 This observation from NASA's Mars Reconnaissance Orbiter shows the
floor of a large impact crater in the southern highlands, north of the
giant Hellas impact basin. Most of the crater floor is dark, with
abundant small ripples of wind-blown material. However, a pit in the
floor of the crater has
exposed light-toned, fractured rock. The light-toned material appears
fractured at several different scales. These fractures, called joints,
result from stresses on the rock after its formation. Joint... Continue reading...
