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...

Max Planck scientists unravel key pathway in the nitrogen cycle The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged by this process. A group of specialized bacteria perform the anammox reaction, but so far scientists have been in the dark about how these bacteria could convert ammonia to nitrogen in the complete...

Cat Urine To Power Space Travel?

Will our next generation of space travel be powered by cat urine? Researchers from Radboud University Nijmegen in the Netherlands released a study which details the work of a particular bacterium that turns the smelly contents of your cat box (or any other type of urine) into space fuel, AFP is reporting. The results of the scientists´ work show that the bacterium anammox, first identified in the 1990´s, thrives in the absence of oxygen and transforms ammonium, the...

Technology used to shape rocket fuel tanks could help one German company to form floats for industrial chemical tanks and oil rigs, thanks to funding from ESA. ESA's Ariane 5 rockets steer with small rocket engines firing bursts of hydrazine, a highly volatile fuel stored under high pressure in corrosion-resistant tanks. The best metal for the tanks is Titanium 6/4 because it is a strong and light alloy of titanium, aluminum and vanadium that doesn't react with the hydrazine inside....

On the day running up to launch when a spacecraft is fuelled, ground personnel look more like astronauts than engineers, putting on spacesuit-like protective gear. This is an essential precaution when dealing with the current hydrazine fuel, but a new development could make satellite fuelling no more dangerous than filling up a car. First used in rocket engines by the German Luftwaffe during World War Two, hydrazine remains the main propellant of choice for a satellite's onboard...

Tests conducted on Planck at Europe's Spaceport in Kourou, French Guiana, have confirmed that the satellite's subsystems work perfectly, and the helium dilution cooler tanks have now been filled. While the final clean-up continues, the solar array has been checked, the satellite has been integrated with its launcher adapter and fuelling is complete. The last of the system reference tests, of the telemetry and telecommand subsystem, was completed on 17 March. The tests, carried out over the...

About two weeks ago, Herschel was weighed to record its dry mass before the satellite was fuelled with 256 kg of liquid hydrazine. After switching it on to confirm normal function, engineers integrated the fuelled satellite with the Ariane 5 adapter. On 26 March, the satellite's weight was measured with reference to calibrated masses for maximum accuracy. After this it was moved to another building on the launch site to begin fuelling operations. Herschel fuels up Herschel will use its...

U.S. scientists say they have developed a new process for mass producing the nanomaterial graphene in large quantities. Graphene -- essential in nanotechnology -- is created when graphite is reduced to a one-atom-thick sheet. It is among the strongest materials known and has an attractive array of benefits, the scientists said. UCLA researchers from the California NanoSystems Institute, led by Professors Yang Yang and Richard Kaner, have developed a method of placing graphite oxide paper...

The U.S. Navy's February missile shoot down of a spy satellite was unnecessary, a Harvard scientist and former NASA employee said. Yousaf Butt filed a Freedom of Information Act request asking for the National Air and Space Agency's re-entry threat analysis from the disabled USA-193 satellite. His conclusions contradict the government's official explanation that the satellite's hydrazine fuel tank posed a health hazard. Butt described government modeling as oversimplified and biased...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
