The American company Deep Space Industries, Inc. has announced its intention to extract minerals and water from asteroids. We know that asteroids, including the many that pass close to Earth called NEO (Near-Earth Objects), can contain a lot of water and minerals such as iron, gold, platinum, nickel and other useful both for the expansion of humanity into the solar system and for our needs on Earth.

The Cassini space probe has been orbiting Saturn for more than eight years and yet again in October 2012 it took a series of stunning images of this planet. Cassini was positioned in Saturn’s shadow and from that position it was able to take photographs of the dark side of the planet and its rings as previously happened only in 2006.

Yesterday, NASA’s GRAIL (Gravity Recovery and Interior Laboratory) twin spacecraft Ebb and Flow ended their mission crashing on the Moon. The site of Ebb and Flow impact was named Sally K. Ride Impact Site in honor of the first American woman to travel in space, who unfortunately passed away last July.
