Decades-Old Soviet Reflector Spotted On the Moon 147

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

Geomagnetic Storm In Progress 110

shogun writes "The National Oceanic and Atmospheric Administration reports a strong geomagnetic storm is in progress. The shuttle, ISS and GPS systems may be affected." They think this storm was caused by a weak solar flare on April 3rd. As you may expect, this has caused some unusually impressive northern lights since it started. What you may not expect is a photograph from Japanese astronaut Soichi Noguchi aboard the International Space Station showing the aurora from orbit. He apparently tweets a lot of pictures from space. He and his crewmates have taken over 100,000 pictures since coming aboard the ISS.

Why Is a Laptop's Battery Dearer Than a Lawnmower's? 427

Barence writes "PC Pro's contributing editor Paul Ockendon has bought a new lawnmower powered by lithium-ion batteries — part of a recent flood of such lithium-ion-powered garden and workshop tools which are taking over from NiCd and NiMH thanks to lighter weight, longer life and lack of the pernicious 'memory effect.' This is pretty much the same battery technology used in laptops, mobile phones and MP3 players, so volume manufacture is already established. Yet laptop manufacturers charge more per Watt-hour than lawnmower makers. This blog investigates whether such a seemingly ludicrous situation can be justified."
