anti-geyser testing
2014-08-12 03:00:56

Megan Davidson, NASA Marshall Space Flight Center Let's be honest -- geysers are really cool. You've got an eruption of water and vapor that can burst to heights of 185 feet. What's not to like about that? When building propellant tanks for the world's most powerful rocket, NASA engineers want to make sure Old Faithful stays in Yellowstone. So beginning Aug. 5, anti-geyser testing is underway at NASA's Marshall Space Flight Center in Huntsville, Alabama, for the agency's Space Launch...

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...

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...

Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies. The aluminum-ice, or ALICE, propellant might be used to launch rockets into orbit and for long-distance space missions and also to generate hydrogen for fuel cells, said Steven Son, an associate professor of mechanical...

Aerosol spray is a dispensing system that creates an aerosol mist of liquid particles. The liquid is usually contained in a bottle under liquid pressure that is released when the valve is opened. As the gas in the can expands to drive out the liquid some of the propellant evaporates to maintain an even pressure. Erick Rotheim invented the first aerosol spray can in 1926. Lyle Goodhue and William Sullivan were the first to put it to good use and are credited as the inventors of the modern...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
