X-51A Waverider
2012-08-13 16:14:30

Lee Rannals for redOrbit.com - Your Universe Online The next generation of flight is undergoing a test tomorrow over the Pacific Ocean, paving the way for non-stop Paris trips in just a few hours in the future. The X-51A WaveRider is being prepared at Edwards Air Force Base in the Mojave Desert. This aircraft could take you from New York to London in less than an hour. The experimental aircraft uses a "scramjet" engine that allows it to travel at hypersonic speeds, reaching Mach 4.5...

Space Launch System Advanced Booster Proposals Selected By NASA
2012-07-15 07:32:54

redOrbit Staff & Wire Reports - Your Universe Online NASA reports that it has selected six proposals to improve the cost, dependability and performance of an advanced booster for the Space Launch System (SLS), a heavy-lift rocket that will provide an entirely new capability for human exploration beyond low Earth orbit. For the next phase, engineering demonstrations and risk reduction concepts for SLS will be developed by the awardees. Individual awards will vary with a total NASA...

Lee Rannals for redOrbit.com - Your Universe Online The U.K. government is embracing the future by working on regulations in order to allow the operation of spaceplanes. The new regulations would enable launch systems like the Skylon concept being developed by Reaction Engines Limited (REL) to take place in the U.K. Currently, these types of vehicles are prohibited from using European airspace, but the government is looking to change that. REL's Skylon vehicle would take off...

NASA'S Space Technology Program has selected 14 technologies for development and demonstration on commercial reusable suborbital launch vehicles. The selected proposals offer innovative cutting-edge ideas and approaches for technology in areas including active thermal management, advanced avionics, pinpoint landing and advanced in-space propulsion. They also address many of the high-priority technology needs identified in the recent National Research Council's Space Technology Roadmaps and...

NASA Surpasses Test Facility Record With J-2X Powerpack Test
2012-06-10 04:53:41

NASA's Stennis Space Center near Bay St. Louis, Miss., broke its own record Friday when it conducted a test on the new J-2X powerpack. The test lasted for 1,150 seconds, surpassing the previous record by more than a full minute. For NASA, the test marked a milestone step in development of a next-generation rocket engine to carry humans deeper into space than ever before. For Stennis, the 19-minute, 10-second test represented the longest duration firing ever conducted in the center's A Test...

Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
