Scientists say decaying dark matter might be responsible for x-ray emission
Cambridge, Mass. (UPI) Jun 25, 2013 -
Dark matter is everywhere. According to astronomers, it makes up some 80 percent of all matter in the universe. But since it doesn't absorb or emit light, scientists have never seen dark matter. They don't even know what it is exactly.
But a recent spike of x-rays originating from 70 different galaxy clusters has some scientists excited at the off chance it's a signal from decaying dark ...

Raytheon touts blimp-borne radar system
Tewksbury, Mass. (UPI) Jun 25, 2013 -
Raytheon has announced its blimp-borne radar previously used for testing is now available for operational deployment as a strategic asset.
The system is called JLENS - or Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System - which is composed of an integrated radar system on two tethered, 80-yard aerostats.
The aerostats fly at altitudes of 10,000 feet above ...

Bringing back our spaceplane
Paris (ESA) Jun 26, 2014 -
Yesterday, the ship and crew aiming to recover Europe's unmanned IXV spacecraft in November had a practice run off the coast of Tuscany, Italy.
They retrieved a prototype of the suborbital IXV Intermediate eXperimental Vehicle, the same model flown last year in a splashdown test off the east coast of Sardinia.
A crane dropped the two-tonne vehicle into the water for the crew to pract ...

Orion Parachute Test Hits No Snags
Washington DC (SPX) Jun 26, 2014 -
NASA completed the most complex and flight-like test of the parachute system for the agency's Orion spacecraft on Wednesday.
A test version of Orion touched down safely in the Arizona desert after being pulled out of a C-17 aircraft, 35,000 feet above the U.S. Army's Yuma Proving Ground.
It was the first time some parachutes in the system had been tested at such a high altitude. Engi ...
