Mars rover beams back spectacular photos, NASA greeting
Mars rover: NASA's Curiosity Mars rover has beamed home some extraordinary images of Mount Sharp, the three-mile-high mountain near the rover's landing site. Curiosity has also sent back a greeting from NASA administrator Charles Bolden, the first human voice ever to be broadcast from another planet.

On Mars: It's Curiosity's moment to shine, but MAVEN is in the works (+video)
In 2014, Curiosity and MAVEN are slated to team up to help scientists unravel the mystery behind Mars' vanishing atmosphere: How did a wet, warm planet lose that thin layer that can preserve the building blocks of life?

'Star Trek' actors star in new Mars rover landing videos (+video)
William Shatner and Wil Wheaton, the 'Star Trek' icons who portrayed Captain Kirk and Wesley Crusher, appear in two new NASA videos promoting the Curiosity Mars rover, which is scheduled to land on Mars on Aug. 5.

Sudden Greenland ice sheet melt baffles scientists (+video)
Satellite images have shown melting over 97 percent of the surface of Greenland's ice sheet in just four days, an event thought to occur every 150 years on average.

Huge solar eruption could make for dazzling northern lights (+video)
A giant solar eruption may bring an exceptional weekend northern lights display for those as far south as California and Alabama, a NASA scientist says.
-
Humongous solar flare erupts in our direction (+video)
The strongest solar storm of the summer so far could send a wave of charged particles toward our planet that could supercharge northern lights displays, NASA scientists say.
-
Evidence for ancient life on Mars could be just below surface, new study finds (+video)
Researchers say that evidence of ancient life on Mars could take the form of simple organic molecules lying just beneath the Red Planet's surface, and that it could be detectable by NASA's newest rover, which is scheduled to touch down on the planet next month.

Facing rising costs, NASA scraps X-ray space telescope mission (+video)
NASA is canceling work on a new space telescope that was running significantly over budget. The GEMS telescope was intended to study black holes and neutron stars.

Solar storm could become severe 'bell ringer' in next 24 hours (+video)
Solar storm forecasters say the particles disgorged in a massive solar flare could strike Earth in a particular way, which would make a currently moderate solar storm more severe.

Ice, ice baby: Old arctic ice disappearing faster than younger thin ice
Typically the thicker, older ice survives through the summer melt season (hence, it's called multi-year ice), while the younger ice that forms over the winter melts as quickly as it formed.

'Alien' matter from beyond solar system discovered by NASA
This so-called interstellar material was spotted by NASA's Interstellar Boundary Explorer, a spacecraft that is studying the edge of the solar system from its orbit about 200,000 miles above Earth.
-
Huge asteroid may be packed with water ice
The surface of Vesta — the second-largest object in the main asteroid belt between Mars and Jupiter — appears to be quite dry. But water ice may lurk underground over roughly half of the huge space rock's area, particularly near the poles, researchers said.
-
Comet's fiery plunge may tell us how planets form
For the first time, scientists have caught a glimpse of a comet's final minutes before it was vaporized by the sun. The comet was flying at about 1.4 million miles an hour.

Mars explorer 'Curiosity' set for Saturday launch
NASA's Mars explorer Curiosity, the most capable robotic rover ever built for taking the measure of a planet, is to launch Saturday morning. Curiosity will analyze the layered terrain in Gale Crater to read in its rocks the history of the environment there.

Mars science lab 'Curiosity' to launch 'extraterrestrial real-estate appraisal'
After a decade of "following the water," planetary scientists want to see if water co-existed with other critical environmental conditions that could have allowed simple forms of life to emerge.
-
Prototype of next-generation weather satellite: Can it go to work fast enough?
After cost overruns and years of delay, the US is set to launch a prototype weather satellite before dawn Friday. Its data are badly needed as the number of Earth-observing satellites dwindle.
