March 31, 2008 -- Could life exist beneath Enceladus? A recent flyby of Saturn's icy moon has bolstered this fascinating idea. Two years ago, images from the robotic Cassini spacecraft orbiting Saturn led astronomers to the undeniable conclusion that Saturn's moon Enceladus was spewing fountains of gas and ice crystals through cracks in its surface dubbed tiger stripes.

Last month, Cassini dove through some of these plumes and determined that they contained water vapor laced with small amounts of methane as well as simple and complex organic molecules.    » read more »

HAMPTON, Va.- NASA released Friday a photograph of the nearly 20,000-pound Orion space capsule mock-up being loaded into a C-17 cargo aircraft on Thursday, March 27, at NASA's Langley Research Center in Hampton, Va. The mock-up was fabricated at Langley.

The C-17 will transport the mock-up to NASA's Dryden Flight Research Center in Edwards, Calif. In late 2008, the full-size structural model will be propelled off a simulated launch pad at the U.S. Army's White Sands Missile Range in New Mexico to test the spacecraft's astronaut escape system, which will ensure a safe, reliable method of escape for astronauts in case of an emergency.    » read more »

2008 March 20 -- Today, the Sun crosses the celestial equator heading north at 0548 UT.

Known as the equinox, the geocentric astronomical event marks the first day of spring in the northern hemisphere and autumn in the south.

Equinox means equal night and with the Sun on the celestial equator, Earth dwellers will experience nearly 12 hours of daylight and 12 hours of darkness. Of course, for those in the north, the days will grow longer with the Sun marching higher in the sky as summer approaches.

March 14, 2008 -- WASHINGTON - NASA will hold a media teleconference at 2 p.m. EDT on Wednesday, March 19, to report on the first-ever detection of the organic molecule methane in the atmosphere of a planet orbiting a distant star.

Though the planet is too hot to support life as we know it, the finding demonstrates the ability to detect organic molecules spectroscopically around Earth-like planets in habitable zones around stars.

Briefing participants are:
- Dr. Mark Swain, NASA Jet Propulsion Laboratory, Pasadena, Calif.    » read more »

March 13, 2008 -- HUNTSVILLE, Ala. -- Each year around this time, John Tripp walks across a lunar surface, pondering the challenges ahead for explorers brave enough to take on its cratered terrain. For now, his "moon" is a winding ribbon of cement footpaths looped around Huntsville's famed U.S. Space and Rocket Center, where Tripp is a construction foreman.    » read more »

March 12, 2008 -- HAMPTON, Va. - NASA has completed production of hardware for use in the first flight test of the astronaut escape system for the Constellation Program's Orion crew capsule.

The hardware - a structure that simulates the Orion crew module - was designed and fabricated at NASA's Langley Research Center in Hampton, Va. The structure represents the size, outer shape and mass characteristics of the space capsule being designed to transport astronauts first to the International Space Station then on to the moon by 2020.    » read more »
