What would our solar system look like if visitors from other worlds took a series of pictures? NASA's MESSENGER spacecraft did just that by piecing together the first portrait of our solar system from the inside looking out. Comprised of 34 images, the mosaic provides a complement to the solar system portrait--from the outside looking in--taken by Voyager 1 in 1990. "Obtaining this portrait was a terrific feat by the MESSENGER team," says MESSENGER principal investigator Sean Solomon, of the...

A new analysis based on data from NASA's Cassini spacecraft finds a causal link between mysterious, periodic signals from Saturn's magnetic field and explosions of hot ionized gas, known as plasma, around the planet. Scientists have found that enormous clouds of plasma periodically bloom around Saturn and move around the planet like an unbalanced load of laundry on spin cycle. The movement of this hot plasma produces a repeating signature "thump" in measurements of Saturn's rotating magnetic...

The first spacecraft designed by NASA to orbit Mercury is giving scientists a new perspective on the planet's atmosphere and evolution. Launched in August 2004, the Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, known as MESSENGER, conducted a third and final flyby of Mercury in September 2009. The probe completed a critical maneuver using the planet's gravity to remain on course to enter into orbit around Mercury next year. Data from the final flyby has revealed the...

COLUMBIA, Md., Oct. 2 /PRNewswire-FirstCall/ -- On September 29, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, more commonly referred to as "MESSENGER," flew within 142 miles of Mercury's surface. This was the spacecraft's third and final flyby of the planet. Designed, built, managed, and operated by the Johns Hopkins University Applied Physics Laboratory (APL) for NASA's Science Mission Directorate, MESSENGER is scheduled for a 2011 insertion into...

Astronomers have theorized that the unexplained terrain on one of Saturn's icy moons might have happened when the moon went from a relatively fast-spinning body to one spinning more slowly, BBC News reported. The bulging ridge of Iapetus, which encircles the moon's equator and reaches an altitude of over 12 miles in certain areas, was discussed in detail during a presentation at the Lunar and Planetary Science Conference in Texas. James Roberts and colleagues at the Johns Hopkins University...

 Using a NASA radar flying aboard India's Chandrayaan-1 spacecraft, scientists are getting their first look inside the moon's coldest, darkest craters. The Mini-SAR instrument, a lightweight, synthetic aperture radar, has passed its initial in-flight tests and sent back its first data. The images show the floors of permanently-shadowed polar craters on the moon that aren't visible from Earth. Scientists are using the instrument to map and search the insides of the craters for water ice....

Researchers using a powerful instrument aboard NASA's Mars Reconnaissance Orbiter have found a long sought-after mineral on the Martian surface and, with it, unexpected clues to the Red Planet's watery past. Surveying intact bedrock layers with the Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM, scientists found carbonate minerals, indicating that Mars had neutral to alkaline water when the minerals formed at these locations more than 3.6 billion years ago. Carbonates, which...
