Scientists 'read' ash from the Icelandic volcano two years after its eruption Posted: 12 May 2012 11:41 AM PDT In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena.

Meteorite discovery spurs hunt for more pieces Posted: 12 May 2012 07:10 AM PDT Meteorite fragments were recently scattered around Sutter's Mill in California, the same region where the first nugget of gold was found that sparked the Gold Rush in 1848. Scientists believe the meteorites may hold answers to unsolved mysteries about our solar system and the origins of molecules necessary for life. When the Gold Rush began, people headed to California seeking their fortune. Now, with this meteorite hunt, people once again have flocked to this area to search for scientific treasures.

A solution for medical needs and cramped quarters in space Posted: 12 May 2012 07:08 AM PDT Imagine you're an astronaut exploring the surface of Mars, when suddenly you fall ill or injure yourself. As your team struggles to get you safely back to base, you become seriously dehydrated. With their trusty -- and ingenious -- kit, the medical officer hooks into the drinking water supply, using it to create a saline solution that they can inject directly into your blood stream for quick and safe rehydration.

HIFiRE scramjet research flight will advance hypersonic technology Posted: 12 May 2012 07:06 AM PDT A team that includes NASA and the U.S. Air Force Research Laboratory (AFRL) is celebrating the successful launch of an experimental hypersonic scramjet research flight from the Pacific Missile Range Facility on the island of Kauai, Hawaii.

NASA's Space Launch System carries deep space potential Posted: 12 May 2012 07:03 AM PDT NASA's Space Launch System is on track to give America the launch vehicle it will need to send humans deeper into space than ever before, according to officials.

Mojave Desert tests prepare for NASA Mars roving Posted: 12 May 2012 07:01 AM PDT Team members of NASA's Mars Science Laboratory mission took a test rover to Dumont Dunes in California's Mojave Desert this week to improve knowledge of the best way to operate a similar rover, Curiosity, currently flying to Mars for an August landing.

NASA's new carbon-counting instrument leaves the nest Posted: 12 May 2012 07:00 AM PDT Its construction now complete, the science instrument that is the heart of NASA's Orbiting Carbon Observatory-2 (OCO-2) spacecraft -- NASA's first mission dedicated to studying atmospheric carbon dioxide -- has left its nest at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and has arrived at its integration and test site in Gilbert, Ariz.

NASA's Juno spacecraft images Big Dipper Posted: 12 May 2012 06:59 AM PDT In England it is known as the "Plough," in Germany the "Great Cart," and in Malaysia the "Seven Ploughs." Since humanity first turned its eyes skyward, the seven northern hemisphere stars that compose the "Big Dipper" have been a welcome and familiar introduction to the heavens.
