NASA Contracts Company to Develop Replacement Tissues

"We recently discussed one such effort, with Bigelow Aerospace agreeing to a memorandum of understanding to brainstorm with NASA about creating a long-term Moon colony based on inflatable modules.

Now another interesting collaboration has popped up. NASA has signed agreements with GRoK Technologies LLC, a Houston, Texas-based research and development startup, to grow human tissues. (Note: There's a similarly named, but unaffiliated bioinformatics company called GroK Solutions -- beware.)"

NASA Satellite Falls Back To Earth; Landfall in Canada

"CNET, among many other sources, reports that the declining orbit of the Upper Atmosphere Research Satellite has declined all the way; the satellite reentered and broke up in Earth's atmosphere last night, though the exact time, and thus location, of the reentry was unknown at the time. CNET quotes NASA's release, which says the satellite "fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23, and 1:09 a.m. EDT Sept.

Space Shuttle Discovery Takes Last Trip

Space... the Final Frontier. These are the voyages of the Shuttle Discovery. Its mission: to explore strange new worlds; to seek out new life and new civilizations; to boldly go where no man has gone before; Into Retirement.

Mind-Boggling New Images of the Sun

NASA's recently launched Solar Dynamics Observatory is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic 
processes.

A full-disk multi-wavelength extreme ultraviolet image of the sun taken by SDO on March 30, 2010. False colors trace different gas temperatures. Reds are relatively cool; blues and greens are hotter. (NASA image)
Some of the images from the spacecraft show never-before-seen detail 
of material streaming outward and away from sunspots. Others show
 extreme close-ups of activity on the sun's surface. The spacecraft 
also has made the first high-resolution measurements of solar flares 
in a broad range of extreme ultraviolet wavelengths.


Robonaut ready for duty

When Discovery's six astronauts take the final space shuttle ride to orbit in September, there'll be one more rider sitting in the back of the bus: Robonaut 2, the semi-humanoid robot created by NASA and GM.

Space Junk Mess Getting Messier

The already untidy mass of orbital debris that litters low Earth orbit nearly got nastier last month.

A head-on collision was averted between a spent upper stage from a Chinese rocket and the European Space Agency's (ESA) huge Envisat Earth remote-sensing spacecraft.

Space junk tracking information supplied by the U.S. military, as well as confirming German radar data, showed that the two space objects would speed by each other at a nail-biting distance of roughly 160 feet (50 meters).

ESA's Envisat tips the scales at 8 tons, with China's discarded rocket body weighing some 3.8 tons.
