Roasted And Shredded by a Stellar Sidekick

An exhausted star still has some punches to deliver.

"NASA estimates more than 500,000 pieces of hazardous space debris orbit the earth, threatening satellites that support peacekeeping and combat missions. These objects include spent rocket stages, defunct satellites and fragments from other spacecraft that are the result of erosion, explosion and collision. A collision between one of these small pieces of debris and a satellite could release more than 20,000 times the energy of a head-on automobile collision at 65 mph. To help address the threat, DARPA created SpaceView, a space debris tracking project that provides amateur astronomers with the means to make a difference. Amateur astronomers will have their first opportunity to sign up in person for the program at the Arizona Science and Astronomy Expo in Tucson, November 10-11, 2012." More

NASA OSIRIS-REx Mission Wants Amateur Astronomers To Target Asteroids

"A new NASA outreach project will enlist the help of amateur astronomers to discover near-Earth objects (NEOs) and study their characteristics. NEOs are asteroids with orbits that occasionally bring them close to the Earth. Starting today, a new citizen science project called "Target Asteroids!" will support NASA's Origins Spectral Interpretation Resource Identification Security - Regolith Explorer (OSIRIS-REx) mission objectives to improve basic scientific understanding of NEOs. OSIRIS-REx is scheduled for launch in 2016 and will study material from an asteroid."
