Chuck Bednar for redOrbit.com - Your Universe Online The discovery of hidden signs of consciousness in vegetative-state patients could help doctors determine if people are aware even if they appear to be unresponsive, according to research published in the journal PLOS Computational Biology. According to BBC News health reporter Smitha Mundasad, doctors typically consider patients who have suffered severe brain trauma to be unaware of their surroundings, even if they appear to be awake....

Chuck Bednar for redOrbit.com - Your Universe Online A mountain-sized comet called C/2013 A1 will pass within 87,000 miles of Mars on Sunday afternoon, bringing it closer to the Red Planet than the Earth is to the moon and nearer than any comet in the past one million years. C/2013 A1, also known as Comet Siding Spring in honor of the Australian observatory where it was first discovered in January 2013, is expected to come closest to Mars at 2:27pm EDT Sunday afternoon, said ABC News...

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!"...

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

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...

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 -- 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...
