Definitive clue to cosmic ray's source
With NASA's gamma-ray space telescope, Fermi, international collaboration including JAXA found conclusive evidence that high-energy protons observed as cosmic rays are produced in supernova remnants. The findings are reported in the Feb 15th issue of the journal Science.

Towards Realization of a Soft Atmospheric Entry Vehicle
How was the Shiitake Mushroom-Type Experimental Vehicle Made?
Entry to the atmosphere is an unavoidable passage when returning from outer space or landing explorers on atmospheric planets such as Mars. The most difficult hurdle to entry is aerodynamic heating. To overcome this, a "deployable-type, flexible-membrane-structure aeroshell" was proposed, where an air-brake like umbrella unfolds to slow down the vehicle, and its effectiveness confirmed by computer simulation, wind-tunnel, balloon, and sounding-rocket experiments.
