a timely reality check |
 Houston, Texas (AFP) May 20, 2009 
US astronauts on the shuttle Atlantis said Wednesday they were amazed at how successful their grueling mission to revamp the aging Hubble telescope had been, given the number of tough obstacles they faced. Speaking to reporters earlier, the smiling seven crew members spoke with pride of their mission to give the 19-year-old stargazer a new lease on life to peer back further into the origins ... read more 
Moffett Field CA (SPX) May 21, 2009Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets, born in the deep freeze of the solar system's outer edges. The crystals would have begun as non-crystallized silicate particles, part of the mix of gas and dust from which the solar system developed. A team of astronomers believes they have foun ... more

Houston TX (SPX) May 21, 2009Unlike other Space Flight Simulation studies which mimic micro gravity by placing subjects in a bed with their heads inclined six degrees lower than their feet, The Lunar Analog study is a 9.5 degree head up study. Physics determines the 9.5 degrees incline - at this angle, the gravity force through the subject's legs along the long axis is 1/6th of the subject's body weight. The stu ... more 
Boulder CO (SPX) May 21, 2009NASA-funded study indicates that an intense asteroid bombardment nearly 4 billion years ago may not have sterilized the early Earth as completely as previously thought. The asteroids, some the size of Kansas, possibly even provided a boost for early life. The study focused on a particularly cataclysmic occurrence known as the Late Heavy Bombardment, or LHB. This event occurred approximatel ... more  
Berkeley CA (SPX) May 20, 2009The world's largest and longest-running volunteer computing project, SETI@home, celebrates its tenth anniversary this month with 140,000 participants and 235,000 computers powering the search for intelligent signals from space. No extraterrestrials have been found yet. But the project will hold a day-long symposium at the University of California, Berkeley's Space Sciences Laboratory on M ... more 
Washington DC (SPX) May 20, 2009The Hubble Space Telescope has been with us for nearly two decades. In that time, its breathtaking images have captured people's imaginations and its groundbreaking science has revealed some of the many secrets of our universe. This morning, at precisely 8:57 a.m. ET, a carefully orchestrated maneuver was carried out 350 miles above the Atlantic coastline of Africa, marking the successful ... more |

Houston, Texas (AFP) May 18, 2009NASA astronauts tuned up the Hubble Space Telescope for the final time Monday, equipping the aging stargazer with new batteries, a precision pointing device and solar shielding during a sentimental work session. John Grunsfeld and Drew Feustel spent six hours refurbishing the 13.2 meter (43.5 foot) long telescope, hoisted into the cargo bay of the shuttle Atlantis last week for an ambitious ... more 
Greenbelt MD (SPX) May 19, 2009Space is not a hospitable place, and when scientists and engineers design and build new components for the Hubble Space Telescope, that fact is always clearly in mind. Hubble must endure harsh temperature swings of 215 F, micro-meteor impacts and exposure to solar radiation. On top of that, before a spacecraft like Hubble can operate in orbit, it has to survive the trip to get there. ... more 
Greenbelt MD (SPX) May 19, 2009The Hubble Space Telescope has logged millions of miles and taken thousands of pictures since its launch in 1990, thanks in part to the around-the-clock efforts of a small group of dedicated engineers and technicians at NASA's Goddard Space Flight Center in Greenbelt, Md. "Hubble is a truly amazing telescope, but as sophisticated as it is, it can't function completely on its own," says Hub ... more |
