Nea Kameni volcano movement captured by Envisat
Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes. View More (2012-05-23)
You're beautiful, Vesta
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks about science. View More (2012-05-11)
TDRS-4 Mission Complete; Spacecraft Retired From Active Service

The vast potential of ESA's upcoming Sentinel-2 satellites came into focus last week at a symposium in Italy on how they will benefit current and future projects that exploit Earth observation data. View More (2012-05-07)
Report warns of rapid decline in US Earth observation capabilities; next-generation missions hindered by budget shortfalls, launch failures
A new National Research Council report says that budget shortfalls, cost-estimate growth, launch failures, and changes in mission design and scope have left U.S. earth observation systems in a more precarious position than they were five years ago. View More (2012-05-03)
WSU astrobiologist proposes fleet of probes to seek life on Mars
A Washington State University astrobiologist is leading a group of 20 scientists in calling for a mission to Mars with "a strong and comprehensive life detection component." View More (2012-04-24)
EARTH: US Navy navigates a sea change in the Arctic
The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism.

NASA spacecraft reveals recent geological activity on the moon
New images from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft show the moon's crust is being stretched, forming minute valleys in a few small areas on the lunar surface. View More (2012-02-22)
Surface of Mars an unlikely place for life after 600 million year drought, say scientists
Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface, according to researchers who have been carrying out the painstaking task of analysing individual particles of Martian soil. View More (2012-02-06)
IBEX team, UNH scientist present mission findings today at NASA press conference
Space scientists, including researchers from the University of New Hampshire (UNH), today described the first detailed analyses of samples of captured interstellar neutral atoms - raw material for the formation of new stars, planets, and human beings. View More (2012-02-01)
SwRI-led RAD measures radiation from solar storm
The largest solar particle event since 2005 hit the Earth, Mars and the Mars Science Laboratory spacecraft travelling in-between, allowing the onboard Radiation Assessment Detector to measure the radiation a human astronaut could be exposed to en route to the Red Planet. View More (2012-01-30)
Vesta Likely Cold and Dark Enough for Ice
Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun.
