Future SLS Missions May Benefit From Marshall-Developed Hardware For Propellant Tanks
2014-07-15 03:30:45

By Megan Davidson, NASA Take a two-liter bottle, and fill it with water. Now, turn it upside down. Did you see a lot of bubbles as the liquid drains rapidly from the top? That's because air is trying to get back in the bottle due to the low pressure created in the space above the liquid as it runs out. [ Watch the Video: 'Diffusing' In Propellant Tanks May Benefit Future SLS Missions ] When it comes to liquid propellant tanks for rockets, the same scenario applies. While the engines...

CENTENNIAL, Colo., March 18, 2014 /PRNewswire/ -- NASA's Launch Services Program announced today that it selected United Launch Alliance's (ULA's) proven Atlas V vehicle to launch its next-generation sun explorer called Solar Orbiter. This award resulted from a competitive procurement under NASA Launch Services contracts that considered multiple launch providers. "We are honored that NASA has selected ULA to provide the launch service for this exciting science mission," said Jim...

NASA Looks To Robots To Refuel And Repair Satellites In Orbit
2014-03-07 13:12:24

Lee Rannals for redOrbit.com - Your Universe Online NASA is using the International Space Station (ISS) as a test bed for technologies that could refuel and repair existing satellites in orbit. The space agency said it is preparing another round of demonstrations on the space station to test the new technology. This testing will focus on real-time relative navigation, spacecraft inspection and the replenishment of cryogens in satellites that were not initially built for in-flight...

Lunar Missions Of The Future Could Refuel In Space
2014-03-05 13:20:32

Lee Rannals for redOrbit.com - Your Universe Online MIT scientists have come up with a concept to create gas stations in space in order to help fuel future lunar missions. Current missions require spacecraft to carry fuel in case of emergency, but this extra fuel means there is less room for space agencies to launch heavier payloads. The team at MIT has come up with two cost-efficient fuel station designs in space that take advantage of the “contingency propellant” that spacecraft...

NASA has selected 10 university-led proposals for study of innovative, early stage space technologies that address high priority technical needs America's space program must master to enable future missions. The one-year grants from NASA's Space Technology Research Grants Program are worth about $250,000 each, with an additional year of research possible. Selected proposals address technology challenges that may improve astrophysics scientific instruments, oxygen recovery for space life...

Lasting Propulsion And High Speeds For Deep Space Missions Provided by NEXT

[ Watch The Video - Gridded Ion Thruster ] NASA Ion propulsion used to exist only in the imagination of science fiction writers. But after years of research and development NASA is poised to equip some of its most important deep space missions with ion engines that can nudge spacecraft using charged particles accelerated to blistering speeds of up to 90,000 miles per hour.  And in the vastness of space, those engines need to push continuously for years. NASA’s Evolutionary Xenon...

NASA has selected a team led by Ball Aerospace & Technologies Corporation of Boulder, Colo., for a technology demonstration of a high performance "green" propellant alternative to the highly toxic fuel hydrazine. With this award, NASA opens a new era of innovative and non-toxic green fuels that are less harmful to our environment, have fewer operational hazards, and decrease the complexity and cost of launch processing. Today's use of hydrazine fuel for rockets, satellites and...

NASA is seeking technology demonstration proposals for green propellant alternatives to the highly toxic fuel hydrazine. As NASA works with American companies to open a new era of access to space, the agency seeks innovative and transformative fuels that are less harmful to our environment. Hydrazine is an efficient and ubiquitous propellant that can be stored for long periods of time, but is also highly corrosive and toxic. It is used extensively on commercial and defense department...

NASA May Develop Fueling Station In Space
2011-10-24 11:29:11

The New York Times reported on Saturday that NASA is considering plans to place fuel stations in space for spacecraft to fill back up before heading to the moon or Mars. The report said engineers will meet at NASA headquarters in Washington next month to discuss how propellant depots, as NASA calls it, could be used to reach farther into space. The Times said NASA performed study of propellant depots, which found that the budget needed for the project from 2012 through 2030 would be $60...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
