Remember the floating training remote in Star Wars? Some people have done DIY versions of the remote that can levitate on your desktop. However, leave it to NASA to create the real thing and call it SPHERES: Synchronized Position Hold, Engage, Reorient, Experimental Satellites: robotic bowling balls (OK, 18-sided polyhedron satellites) with autonomous propulsion, power, avionics, software, communications, and metrology subsystems, that fly freely in the ISS. First tested in 2006, they have been upgraded with Android smartphones, which makes them (for now) the less terrifying item in Google's growing robotic arsenal.

One small step for a robot, one giant leap for robot-kind... but not yet. The Robonaut R2 (sic) will have to wait at least another three weeks, as the final mission of Space Shuttle Discovery is delayed.
Real robot drama is happening on Mars today. Spirit, racing for her life to find shelter before winter, injured and underpowered after four years of hard labor, may have made her most significant find yet. The broken foot she's dragged behind her for the past two years unexpectedly uncovered evidence of a once-wet Mars with conditions theoretically hospitable for primitive life.
