NASA's Stardust spacecraft spent its Valentine's Day getting cozy with a comet, snapping more than 70 photographs of Tempel 1 during a Monday flyby, the US space agency has announced. Stardust flew past Tempel 1 at speeds in excess of 24,000mph, AP Science Writer Alicia Chang reported on Tuesday. Officials from the NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California report that the time of closest approach was 11:39pm EST, when the craft passed within 112 miles of the comet. As of...

NASA's Stardust spacecraft marked its 12th anniversary in space on Monday, Feb. 7, with a rocket burn to further refine its path toward a Feb. 14 date with a comet.The half-minute trajectory correction maneuver, which adjusts the spacecraft's flight path, began at about 1 p.m. PST (4 p.m. EST) on Monday, Feb. 7. The 30-second-long firing of the spacecraft's rockets consumed about 69 grams (2.4 ounces) of fuel and changed the spacecraft's speed by 0.56 meters per second (1.3 mph).NASA's plan...

NASA's Stardust spacecraft has downlinked its first images of comet Tempel 1, the target of a flyby planned for Valentine's Day, Feb. 14. The images were taken on Jan. 18 and 19 from a distance of 26.3 million kilometers (16.3 million miles), and 25.4 million kilometers (15.8 million miles) respectively. On Feb. 14, Stardust will fly within about 200 kilometers (124 miles) of the comet's nucleus. "This is the first of many images to come of comet Tempel 1," said Joe Veverka, principal...

WASHINGTON, Jan. 19, 2011 /PRNewswire-USNewswire/ -- NASA's Stardust-NExT spacecraft is nearing a celestial date with comet Tempel 1 at approximately 11:37 p.m. EST, on Feb. 14. The mission will allow scientists for the first time to look for changes on a comet's surface that occurred following an orbit around the sun.

NASA announced on Wednesday that its Stardust-NExT spacecraft will rendezvous with comet Tempel 1 on Valentine's Day. The space agency said that the mission will allow scientists to look for changes on the comet's surface that took place after an orbit around the sun. The spacecraft will take high-resolution images during the encounter, and will attempt to measure the composition, distribution, and flux of dust emitted into the coma. According to NASA, the mission will expand the...

The biological effects of general anesthesia are more closely related to those of a coma than natural sleep, claims a new study published in Thursday's edition of the New England Journal of Medicine. While often times doctors and patients describe being under anesthesia as something similar to going to sleep, the researchers behind the new study have found "significant differences" between the two states, Julie Steenhuysen of Reuters reported on Wednesday. For example, while sleep usually...

Eighty-six days out from its appointment with a comet, NASA's Stardust spacecraft fired its thrusters to help refine its flight path. The Stardust-NExT mission will fly past comet Tempel 1 next Valentine's Day (Feb. 14, 2011). It will perform NASA's second comet flyby within four months. "One comet down, one to go," said Tim Larson, project manager for both the Stardust-NExT mission and the EPOXI mission -- which successfully flew past comet Hartley 2 on Nov. 4. The trajectory correction...

Findings may help prevent brain damage in vulnerable patients Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO. ECMO, used to temporarily oxygenate the blood of patients whose heart and lungs are too weak or damaged to do so on their own, is most often used as a...

Initial science results on comet released from University of Maryland, much more to come UMD scientists say. One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-led EPOXI mission as it zipped past comet Hartley 2 last week is that dry ice is the 'jet' fuel for this comet and perhaps many others. Images from the flyby show spectacular jets of gas and particles bursting from many distinct spots on the surface of the comet. This is the...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
