NASA Considers Shooting Space Junk With Lasers

http://www.wired.com/wiredscience/2011/03/lasering-space-junk/

“In the new study, the researchers suggest focusing a mid-powered laser through a telescope to shine on pieces of orbital debris that look like they’re on a collision course. Each photon of laser light carries a tiny amount of momentum. Together, all the photons in the beam can nudge an object in space and slow it down by about 0.04 inches per second.

Shining the laser on bits of space litter for an hour or two a day should be enough to move the whole object by about 650 feet per day, the researchers show. That might not be enough to pull the object out of orbit altogether, but preliminary simulations suggest it could be enough to avoid more than half of all debris collisions.”

Overwhelming iPad 2 demand continues, Apple’s online orders now ship in 4-5 weeks

http://www.appleinsider.com/articles/11/03/15/overwhelming_ipad_2_demand_continues_apples_online_orders_now_ship_in_4_5_weeks.html

Apple on Tuesday was forced again to delay estimated shipping times for new iPad 2 orders, as those who buy must now wait four to five weeks for their order to be sent.

Yet another delay comes as stock of the iPad 2 around the U.S. is believed to be entirely sold out at all locations, including Apple’s retail stores and partners. Some select Apple stores with new shipments of the iPad 2 are set to open early today, while many other stores await more stock in the face of crushing demand.”
