AURORAS UNDERFOOT: Flying the last mission of NASA's 30-year shuttle program, the crew of Atlantis has witnessed a beautiful display of auroras from Earth orbit--and there might be more in the offing. Visit http://spaceweather.com for photos and the geomagnetic forecast.
ASTEROID VESTA: This weekend, NASA's Dawn spacecraft is entering orbit around Vesta for a year-long study of the giant asteroid. Dawn's cameras are expected to reveal a primitive world of desolate beauty from close range. As close as Dawn will be, however, you can be even closer; it's actually possible to hold a piece of Vesta in your hand. Authentic Vesta meteorites are now available in the Space Weather Store: http://www.shopspaceweather.
