NASA's Dawn spacecraft, designed to complete a year-long study of the asteroid Vesta, made its first detailed observations of the surface on Thursday from a distance of 1,700 miles. Dawn will spend the next several weeks taking images from that altitude. Afterward, it will spiral closer to the asteroid to get a better view. The probe was launched in September 2007 and arrived at its destination in July. Dawn is beginning the first of four planned science orbits during the spacecraft's...

NASA's twin lunar probes "“ GRAIL-A and GRAIL-B - completed their final inspections and were weighed one final time at the Astrotech Space Operations facility in Titusville, Fla., on Tuesday. The two Gravity Recovery and Interior Laboratory (GRAIL) spacecraft will orbit the moon in formation to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon. GRAIL's launch period opens Sept. 8, 2011, and extends through...

WASHINGTON, Aug. 1, 2011 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft, the first ever to orbit an object in the main asteroid belt, is spiraling towards its first of four intensive science orbits. That initial orbit of the rocky world Vesta begins Aug. 11, at an altitude of nearly 1,700 miles (2,700 kilometers) and will provide in-depth analysis of the asteroid. Vesta is the brightest object in the asteroid belt as seen from Earth and is thought to be the source of a large number of...

Dawn took this image over Vesta's northern hemisphere after the spacecraft completed its first passage over the dark side of the giant asteroid. It is northern hemisphere winter on Vesta now, so its north pole is in deep shadow. The Dawn science team is working to determine the significance of the distinct features in this image, which include large grooves or ridges extending for great distances around Vesta. This image was taken by Dawn's framing camera on July 23, from a distance of 3,200...

Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side. The large structure near the south pole that showed up so prominently in previous images is visible in the center of the illuminated surface. Compared to other images, this one shows more of the surface beneath the spacecraft in the shadow of night. Vesta turns on its axis once every five hours and 20 minutes. Dawn entered orbit around Vesta on July 15, 2011, and will spend a year orbiting...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...
