Apollo 16: Footsteps Under High SunWashington DC (SPX) Jul 09, 2010 The lunar module Orion landed in the Descartes Highlands of the moon on April 21, 1972. The Apollo 16 mission targeted a highland region. Originally thought to be a volcanic site, the samples returned by Apollo 16 actually indicated that the highlands of the moon primarily consist of impact-formed rocks (breccias), a substantial scientific result. The featured image is an LROC NAC image of the Apollo 16 landing site, acquired when the sun was nearly overhead, in contrast to a previous image of the ... read more |

The Earth And Moon Formed Later Than Previously Thought
Copenhagen, Denmark (SPX) Jun 08, 2010The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later - perhaps up to 150 million years after the for ... more Next Stop, Titan: Looking At The Land o' Lakes
Pasadena CA (JPL) Jun 07, 2010NASA's Cassini spacecraft will be eyeing the north polar region of Saturn's moon Titan this weekend, scanning the moon's land o' lakes. At closest approach on early morning Saturday, June 5 UTC, which is Friday afternoon, June 4 Pacific time, Cassini will glide to within about 2,000 kilometers (1,300 miles) of the Titan surface. Cassini will make infrared scans of the north polar reg ... more What Is Consuming Hydrogen And Acetylene On Titan
Pasadena CA (JPL) Jun 07, 2010Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan. While non-biological chemistry offers one possible explanation, some scientists believe these chemical signatures bolster the argument for a primitive, exotic form of life or precursor to life on Titan's surface. According to one theory put forth by as ... more |

Europa's Churn Leads To Oxygen BurnMoffett Field CA (SPX) Jun 01, 2010 There may be enough oxygen in the waters of Jupiter's moon Europa to support millions of tons worth of fish, according to a new study. While no one is suggesting there are fish on Europa, this finding suggests the Jovian satellite could be capable of supporting the kinds of life familiar to us here on Earth. Europa, which is roughly the size of Earth's moon, is enveloped by a global ocean about 100 miles deep (160 km), with an icy crust that may be only a few miles thick. From what we know of Eart ... read more |
