Swarming spacecraft to self-destruct for greater good. "Future space probes that operate in cooperative swarms must commit hara-kiri if they begin to fail and risk damaging their comrades, says a recent patent application by NASA.
The agency foresees a day when space missions are undertaken not by one large spacecraft but by swarming formations of much smaller, cheaper ones. Such craft could collectively provide a "floating optics" system for a space telescope comprising separate craft flying in formation, for instance.
However, should one spacecraft in such a swarm begin to fail and risk a calamitous collision with another, it must sense its end is nigh and put itself on a course that takes it forever away from the swarm – for the greater good of the collective."

"We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month, but this is the first time Martian water has been touched and tasted."
