Thundersnow is possibly the coolest-sounding meteorological term I can think of. It happens very rarely, but when it does it’s awesome. Convection strong enough to cause lighting during a snowstorm is simply amazing, as are most things that rare. Through a ridiculous stroke of luck, scientists in Huntsville, AL got a rare opportunity to study this bizarre phenomenon in-depth. As you may know, Huntsville is home to NASA’s Marshall Space Flight Center. There are meteorologists and other scientists there with a barrage of better-than-average instruments that monitored the inner-workings of the snowstorm that hit the area Jan. 9th. They got the most thorough data ever recorded for thundersnow, and observed one bolt of lightning that traveled a whopping 50 miles horizontally before hitting the ground. The fact that such a rare and interesting phenomenon happened right on top of a facility so well-equipped to study it is quite remarkable, and those scientists were very excited to be able to study the thundersnow in such great detail. I look forward to seeing what is learned from this experience. (Via Discovery News)

NASA has been presented with yet another viable commercial option for replacing the Space Shuttle’s role of ferrying astronauts to and from the space station, as well as carrying cargo. A U.S. company called Alliant Techsystems teamed up with Europe’s Astrium to draft the proposal for a new rocket called Liberty. This new rocket would combine research of the now-dead Constellation program with the proven components of the European Space Agency’s Ariane 5 launch system. Since this collaborative effort combines mostly well-proven technology, it would be both cheap and relatively quick to build, shortening the problematic gap between the last Space Shuttle flight and the first availability of commercial access to space. If it truly will shorten said gap, I’m all for it. I hope it’s really as good as it sounds, but things like this always run into unforseen problems/delays. Right now, SpaceX still has the edge simply because it’s already had 2 very successful tests of its launch system, the Falcon 9 rocket and Dragon capsule. But Liberty could give SpaceX a run for their money. Check out the promo video below. (Via Universe Today)
