(PhysOrg.com) -- University of Toronto researchers continue to uncover the mysteries of space. But even the best astronauts in the world are stymied if the spaceship doesn't launch. When the countdown stops, it is often because a hydrogen leak has been detected. One small malfunction in the sensing device can mean millions of dollars lost. http://www.physorg.com/news177096977.html Nanotechnology Tue, 10 Nov 2009 19:10:02 EST news177096977 (PhysOrg.com) -- Last Wednesday, the Ad Astra Rocket Company tested what is currently the most powerful plasma rocket in the world. As the Webster, Texas, company announced, the VASIMR VX-200 engine ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. The test also marks the first time that a small-scale prototype of the company's VASIMR (Variable Specific Impulse Magnetoplasma Rocket) rocket engine has been demonstrated at full power. http://www.physorg.com/news174031552.html Space & Earth Tue, 06 Oct 2009 07:07:36 EST news174031552 (PhysOrg.com) -- With 520 seconds of shake, rattle and roar on July 29, NASA's John C. Stennis Space Center marked the end of an era for testing the space shuttle main engines that have powered the nation's Space Shuttle Program for nearly three decades. http://www.physorg.com/news168264331.html Space & Earth Fri, 31 Jul 2009 13:20:02 EST news168264331 (PhysOrg.com) -- A reusable spaceplane that can take off from a conventional aircraft runway, carry over twelve tonnes to orbit and then return to land on the same runway could be less than a decade away thanks to a one million euro award by the European Space Agency (ESA). http://www.physorg.com/news154280085.html Space & Earth Thu, 19 Feb 2009 15:35:41 EST news154280085 (PhysOrg.com) -- A technology development engine that may help NASA safely return astronauts to the lunar surface has successfully completed its third round of testing. The goal of these tests is to reduce risk and advance technology for a reliable and robust rocket engine that could enable America's next moon landing. http://www.physorg.com/news151172287.html Space & Earth Wed, 14 Jan 2009 16:18:07 EST news151172287
