Watched Wonders of the Universe the other evening. This week was about Pluto, what a totally amazing object. It even generates heat under the mantle by freezing and thawing water! The episode on Mars was fascinating, so much to take in, watched it twice up to now, and more views to come. Pity the narrator does not know what he is talking about. Temperatures reach minus 400C, 5 minutes later this has risen to a top limit of minus 200C, oh and ref pluto's volcanoes the solar systems biggest volcano is Olympic Mons on Mars - warra dork!!

The top-secret X-37B space plane is about to break another recordThe U.S. Air Force's top-secret autonomous space plane, the X-37B, is days away from breaking its own longevity record. The aircraft, which looks like a mini Space Shuttle, will on March 25 begin its record-setting 675th day in orbit, but we still don't know much about what it's doing up there.
The X-37B looks a little like the Space Shuttle, but it's much smaller. It began life as a NASA project but was transferred to the Air Force in 2004 as part of the U.S. military's little-known space program. That's when it moved into the shadows.
