Traveling To Hard-to-reach Destinations Made Easier Thanks To NASA Technologist
2013-08-01 08:22:27

NASA Traveling to remote locations sometimes involves navigating through stop-and-go traffic, traversing long stretches of highway and maneuvering sharp turns and steep hills. The same can be said for guiding spacecraft to far-flung destinations in space. It isn't always a straight shot. A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary...

3D Printed Rocket Parts Pass Hot-Fire Tests
2013-07-25 05:43:55

Lee Rannals for redOrbit.com - Your Universe Online NASA has tested 3D printed rocket parts, showing that the future is bright for the less-expensive methodology. Engineers decided to try 3D printing rocket parts in order to help save NASA and the industry some money, as well as open up new affordable design possibilities for rockets and spacecraft. Now, NASA is saying that tests have shown these rocket engine parts are comparable to those made the old-fashioned way. NASA engineers...

UK Space Agency Invests Into Development Of Air-breathing Rocket Engine

ESA The UK government has announced plans to invest in the development of an air-breathing rocket engine -- intended for a single-stage-to-orbit spaceplane -- following the ESA-managed feasibility testing of essential technology. The 60 million euros investment, provided through the UK Space Agency, will back technical improvements leading to construction of a prototype Synergistic Air-Breathing Rocket Engine, or SABRE. Designed by UK company Reaction Engines Ltd, this unique engine...

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...
