Dr. Tony Phillips, Science@NASA On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away - which would be like a comet passing about 1/3 of the distance between Earth and the Moon. The nucleus of the comet won't hit Mars, but there could be a different kind of collision. "We hope to witness two atmospheres colliding," explains David Brain of the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). "This is a once in a lifetime event!"...

Elizabeth Zubritsky and Nancy Neal-Jones, NASA’s Goddard Space Flight Center A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved. [ Watch: HCN – Inner Coma Of C/2012 F6 (Lemmon) ] “We achieved truly first-of-a-kind mapping of important molecules that help us understand the nature of comets,” said Martin Cordiner, a researcher working in the...

redOrbit Staff & Wire Reports - Your Universe Online After a journey of more than six billion kilometers through the Solar System, the ESA’s Rosetta probe is closing in on comet 67P/Churyumov–Gerasimenko (67P), and with less than a week to go until its arrival, it recently managed to take the comet’s temperature for the first time and has captured images of a coma surrounding its nucleus. Rosetta, which lifted off from a European spaceport in French Guiana in March 2004, has...

WASHINGTON, July 25, 2014 /PRNewswire-USNewswire/ -- NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The comet's nucleus will miss Mars by about 82,000 miles (132,000 kilometers), shedding material hurtling at about 35 miles (56 kilometers) per second, relative to Mars and...

ESA's Rosetta Probe Catches Target Comet 67P Releasing 10 Ounces Of Water Every Second
2014-06-30 14:48:23

Brett Smith for redOrbit.com - Your Universe Online As the European Space Agency’s Rosetta probe drew closer to its target – comet 67P/Churyumov–Gerasimenko – it was able to pick up data that showed the comet is releasing the equivalent of two small glasses of water into space every second, the space agency said. The Rosetta probe was able to detect the rate of water vapor being released through the use of the Microwave Instrument for Rosetta Orbiter (MIRO) from nearly 220,000...

ESA Expects The Unexpected As Rosetta Nears Comet Rendezvous
2014-06-20 09:49:28

April Flowers for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Rosetta spacecraft is the first mission in history to attempt to rendezvous with a comet. The spacecraft will deploy the Philae lander to the surface of the comet and accompany it as it orbits the Sun. The comet in question is 67P/Churyumov-Gerasimenko, which is currently approximately 267,189 miles from the spacecraft. The Rosetta team released a series of images last May that detailed the extended...

Comet Siding Spring Won't Disrupt Martian Orbiters As It Makes Close Approach Of The Red Planet
2014-06-20 07:06:18

April Flowers for redOrbit.com - Your Universe Online Later this year, comet Siding Spring will have a very close brush with Mars. That brush will be so close, in fact, that it lead scientists to worry about the safety of the three spacecraft currently orbiting the planet. Some experts from the University of Maryland (UMD) have used a satellite mounted telescope to observe the "fresh" comet, however, and they find that it poses minimal danger to the Martian spacecraft. Instead, the...

Rosetta at Comet
2014-06-10 16:21:28

NASA Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objective is to arrive at comet 67P/Churyumov-Gerasimenko in August to study the celestial...

ESA's Rosetta Spacecraft Spies Comet Beginning To Form Its Tail
2014-05-16 11:42:34

Brett Smith for redOrbit.com - Your Universe Online The comet targeted for research by the European Space Agency’s Rosetta probe has begun to develop its tail as it zooms closer and closer to the Sun. The probe is maneuvering to align with the comet’s orbit this month and is slated to rendezvous with it in August. On Thursday, the ESA released a series of images showing comet 67P/Churyumov–Gerasimenko developing its tail, or coma. Taken between March 27 and May 4, the...

A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet. It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. "Our findings suggest that PET imaging can reveal cognitive processes that aren't...

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...
