Asteroid sample return mission on slate for 2016

Asteroid sample return mission on slate for NASA in 2016. The asteroid chosen in 1999 RQ36, which is significant.

The space rock has been classified as a potentially hazardous asteroid, since its orbit brings it close to Earth in the year 2182. There is an extremely remote chance (a recent study pegs it at about 1-in-1000) that the 1,900-foot-wide (579-meter) asteroid could pose a threat to Earth.

The strange egg-shaped dwarf planet Haumea is apparently also covered with ice

Truly alien: The strange egg-shaped dwarf planet Haumea is apparently also covered with crystallised ice.

“Since solar radiation constantly destroys the crystalline structure of ice on the surface, energy sources are required to keep it organized. The two that we have taken into consideration are that able to generate radiogenic elements (potassium-40, thorium-232 and uranium-238) from the inside, and the tidal forces between Haumea and its satellites,” [explained] Benoit Carry, co-author of the study and a researcher at the ESAC Centre of the European Space Agency (ESA) in Madrid (Spain).
