U.S. researchers are refining a type of fuel cell to be smaller, less costly and more efficient than traditional models and could provide reliable, clean sources of energy for portable devices such as laptop computers or spacesuits for astronauts.
Raytheon demonstrated its SilentEyes Micro Unmanned Aerial Vehicle (UAV) by ejecting it from an MQ-9 Predator pylon-mounted canister during tests at Edwards Air Force Base, California.
In the next 100 years, Alaska will experience a massive loss of its historic tundra, as global warming allows these vast regions of cold, dry, lands to support forests and other vegetation that will dramatically alter native ecosystems, an Oregon State University researcher said Tuesday.
Proxity Digital Networks, through Cyber Aerospace Corp, an operating subsidiary of Proxity’s On Alert Systems, announces their first generation Individual Unmanned Air Scout (IUAS), known as Cyber Scout, is in test flight mode. Weighing only 10 lbs., the UAV is designed to operate innovative clandestine reconnaissance, surveillance, target acquisition and could be hand-carried into battle to perform hunter-killer missions.
NASA scientists are modifying a sensor so it could look for signs of martian life by reading data from a soil-burrowing ‘mole’ capsule. Researchers at NASA Ames Research Center in California’s Silicon Valley are adapting the Earth observation instrument for potential use during future Mars missions in a search for water, ice, organics and minerals in the soil.
When it enters its final path around the red planet, the Mars Reconnaissance Orbiter will be closer to the martian surface than any other orbiter has ever gone. This closeness will enable the orbiter to get more detailed images than ever before from above the planet’s surface, and its sophisticated suite of science instruments will reveal much more about Mars and its water history. It will also become the first link in a communications bridge back to Earth, an “interplanetary internet” that can be used by numerous international spacecraft in coming years.
Think of large earth moving projects: highway interchanges, coal mines or Boston’s Big Dig. According to Roger LeBaron Hooke, a University of Maine scientist, such activities have propelled humans into becoming arguably the most potent force in shaping the planet, surpassing rivers, wind and other natural phenomena.
The public may never be told why Britain’s first Martian probe – Beagle 2 – disappeared last Christmas as it was about to land on Mars. Investigators have not been able to pinpoint a single failure or shortcoming of the $90 million probe, reporters were told at a London news conference Monday.
Only nuclear energy can slow down the rapid and potentially devastating warming of the earth, a veteran British scientist and environmental campaigner argued on Monday. “Only one immediately available source does not cause global warming and that is nuclear energy,” James Lovelock wrote in an opinion piece published in the Independent newspaper.
Russia’s space agency is seeking to join the European space agency (ESA) but only as an equal member, its director Anatoly Perminov told ITAR-TASS.
He said the issue had been recently discussed with the ESA director Jean-Jacques Dordain. But the discussions dealt with Russia joining as no more than an associate, a status that would give it less power than other nations in the European space alliance.
