Digging Deep For Martian Life
Moffett Field CA (ARC) Jul 24, 2007The European Space Agency (ESA), like NASA, has a plan to explore the solar system. ESA's Aurora Programme includes orbiters, landers, rovers, and ultimately, human exploration of the moon and Mars. ExoMars, a rover scheduled to launch in 2011 and to land on Mars in 2013, is one of Aurora's flagship missions. The ExoMars rover will be capable, for the first time since NASA's Viking missions in ... more Throttling Back To The Moon 
Huntsville AL (SPX) Jul 24, 2007Accelerating from 0 to 60 then slowing down for a stop light is no problem for an ordinary automobile. But if you were piloting a rocketship, it wouldn't be so easy. Most rocket engines are designed to burn full-on (liftoff!) or full-off (coasting through space) with no in-between. And that can be a problem--namely, how do you land this thing? Throttling is crucial for a planetary lander. ... more Researchers Produce Images Of Gases Escaping From Jupiter Moon Io 
Boston MA (SPX) Jul 21, 2007Boston University researchers have published the first clear evidence of how gases from Jupiter's tiny moon's volcanoes can lead to the largest visible gas cloud in the solar system. Jupiter, the largest planet in the solar system, has a moon named Io that is just 100 km larger in radius than Earth's Moon. According to lead researcher Michael Mendillo, professor of electrical and computer engine ... more From Dark Obscurity A Tiny New Saturnian Moon Comes To Light 
Boulder C0 (SPX) Jul 21, 2007Like a hawk's eyes, the high resolution cameras on NASA's Cassini spacecraft have spotted yet another small, previously unknown moon circling giant Saturn and one which may indicate the existence of other small bodies in the same region. The tiny world--presently thought to be only about 2 kilometers (1 mile) wide--orbits at 197,700 kilometers (122,800 miles) from Saturn. Until a name for the mo ... more Where To Next For The NASA Discovery Program 
Cameron Park CA (SPX) Jul 21, 2007The next full-scale mission to be selected for the Discovery Program will be selected in early October, from a set of three finalists including a near-Earth asteroid sample-return mission (which would be very rewarding scientifically, but is already perilously close to the program's official mission cost limit), or a Venus orbiter or lunar orbiter (which would be cheaper, but also somewhat less ... more |

London (UPI) Jul 20, 2007A huge lake hidden beneath Darfur and detected by radar from space could be the key to saving lives in the arid, war-torn region. Plans are under way to dig 1,000 wells that could provide water and help stop the region's war, The Telegraph reported Thursday. A team led by a veteran of NASA's Apollo lunar exploration program used satellite equipment to compose a picture of the 12,000-square-mile ... more Saturn Moon Iapetus Retains Its Youthful Figure 
Pasadena CA (SPX) Jul 18, 2007Saturn's distinctive moon Iapetus is cryogenically frozen in the equivalent of its teenage years. The moon has retained the youthful figure and bulging waistline it sported more than three billion years ago, scientists report. "Iapetus spun fast, froze young, and left behind a body with lasting curves," said Julie Castillo, Cassini scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. ... more Moonshine Can Reflect Lunar Composition 
Phoenix (UPI) Jul 18, 2007U.S. scientists determined that they can predict concentrations of certain minerals on the moon by comparing variations in reflected light. Samples of lunar rocks returned by U.S. astronauts show large variations in titanium oxide concentrations, suggesting complex compositional zonation within the lunar mantle. M.S. Robinson of Arizona State University and colleagues, noting ilminite has ... more NASA Awards Upper Stage Engine Contract For Ares Rockets 
Washington DC (SPX) Jul 17, 2007NASA has signed a $1.2 billion contract with Pratt and Whitney Rocketdyne Inc., of Canoga Park, Calif., for design, development, testing and evaluation of the J-2X engine that will power the upper stages of the Ares I and Ares V launch vehicles. The contract includes ground and test flight engines. It continues work that began on June 2, 2006, under a preliminary letter contract with Pratt and W ... more |

Boulder CO (SPX) Jul 10, 2007Scientists on NASA's Cassini mission to Saturn now have a better understanding of why the odd moon Hyperion has such an unusual appearance. The crucial factor in creating the strange, sponge-like appearance of Hyperion appears to be its extremely low density, say Cassini scientists in a research paper being published in the July 5 issue of the journal Nature. The researchers examined Cassini sp ... more Summer Moon Illusion 
Huntsville AL (SPX) Jun 29, 2007On Saturday night, June 30th, step outside at sunset and look around. You'll see a giant moon rising in the east. It looks like Earth's moon with the usual craters and seas, but something's wrong. This full moon is strangely inflated. It's huge! You've just experienced the Moon Illusion. Sky watchers have known for thousands of years that low-hanging moons look unnaturally big. Cameras don't see ... more NASA Selects Reynolds To Design Emergency Egress System For Orion Astronauts 
Jacksonville FL (SPX) Jun 28, 2007Reynolds, Smith and Hills, a leading facilities and infrastructure consulting firms whose client-centered program structure provides value-added solutions to clients around the world, announced it has been selected by NASA to design the Emergency Egress System for Orion, the next generation space exploration vehicle that is expected to launch in 2014. The new escape system will allow astronauts ... more Thinking Big About Space Telescopes 
Washington DC (SPX) Jun 27, 2007How big? Consider the following: Ares V will be able to place almost 130,000 kg (284,000 lbs; 8% more than the Saturn V rocket of the 1960s) into low Earth orbit. Designed to deliver cargo to the Moon, the rocket would be large enough to carry primary mirrors 8+ meters wide. For comparison, Hubble's mirror measures 2.4 m. "How does a typical astrophysicist work?" Stahl asks. ... more
