Keck observations reveal the more details of Uranus than even the Voyager flyby in 1986
Nextbigfuture - European astronomers have discovered a planet with about the mass of the Earth orbiting a star in the Alpha Centauri system — the nearest to Earth. It is also the lightest exoplanet ever discovered around a star like the Sun. The planet was detected using the HARPS instrument on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile. The results will appear online in the journal Nature on 17 October 2012.

Nextbigfuture - Researchers presented infrared spectroscopy and mass spectrometry analyses of Apollo samples that reveal the presence of significant amounts of hydroxyl inside glasses formed in the lunar regolith by micrometeorite impacts. Lunar regolith is everywhere on the lunar surface, and glasses make up about half of lunar regolith. Finding hydroxl in the glass means that a huge amount of material that could be turned into water on the moon.

Nextbigfuture - Spacex is developing a new more powerful engine that will enable a rocket to take 200 tons of payload to low earth orbit. Musk said the new rocket, which he calls MCT, will be "several times" as powerful as the 1 Merlin series, and won't use Merlin's RP-1 fuel. Beyond adding that it will have "a very big core size", he declined to elaborate, promising more details in "between one and three years".

Nextbigfuture - NASA's Commercial Crew Program (CCP) partner Blue Origin has successfully fired the thrust chamber assembly for its new 100,000 pound thrust BE-3 liquid oxygen, liquid hydrogen rocket engine. As part of Blue's Reusable Booster System (RBS), the engines are designed eventually to launch the biconic-shaped Space Vehicle the company is developing. Blue Origin is a reusable rocket being developed by Jeff Bezos CEO of Amazon.
