GPIM Spacecraft To Validate Use Of "Green" Propellant

NASA Milestone progress is being made in readying NASA’s Green Propellant Infusion Mission (GPIM) for launch in 2016, a smallsat designed to test the unique attributes of a high-performance, non-toxic, “green” fuel on orbit. The GPIM...

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...

Understanding Fluid Slosh To Improve Rocket Safety And Efficiency

NASA Since Robert Goddard's first launch of a liquid propellant rocket in 1926, experts have worked to perfect engine propulsion systems. As launch vehicles have grown in size, fuel and oxidizer tanks have become more complex resulting in unexpected changes in thrust, potentially endangering flight crews and mission success. A team of scientists and engineers at NASA's Kennedy Space Center in Florida is now studying how to better understand this phenomenon and reduce its potential impacts...

NASA Switches To A Greener Rocket Fuel
2013-05-07 16:32:54

Brett Smith for redOrbit.com - Your Universe Online NASA has announced that it will stop using the rocket fuel that has been an aeronautics mainstay since the 1940s and switch to a greener, environmentally-benign propellant. The space agency says that the first space flight powered with this new fuel will take place in 2015. Hydrazine was used to power the first rocket-powered fighter plane in World War II, the Viking Missions of the 1970s, and more recently the Curiosity mission...


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).
