An Asteroid the Size of a Dwarf Planet Is Lurking In Our Solar System
Long-time Slashdot reader fahrbot-bot summarizes an article from LiveScience: There’s a giant asteroid somewhere out in the solar system, and it hurled a big rock at Earth. The evidence for this mystery space rock comes from a diamond-studded meteor that exploded over Sudan in 2008. NASA had spotted the 9-ton (8,200 kilograms), 13-foot (4 meters) meteor heading toward the planet well…

A NASA Mission Is About To Capture Carbon-Rich Dust From a Former Water World
sciencehabit writes: OSIRIS-REx is ready to get the goods. On 20 October, after several years of patient study of its enigmatic target, NASA’s $800 million spacecraft will finally stretch out its robotic arm, swoop to the surface of the near-Earth asteroid Bennu, and sweep up some dust and pebbles. The encounter, 334 million kilometers from Earth, will last about 10 seconds….
