Did Dawn Mission Find Water-Carved Gullies On Vesta Asteroid?
2012-12-07 16:11:58

Michael Harper for redOrbit.com — Your Universe Online In 2007, NASA launched the Dawn Mission to study the asteroid Vesta and dwarf planet Ceres. Carrying a visible camera, a visible and infrared mapping spectrometer, and a gamma ray and neutron spectrometer, Dawn set out on an 8 year mission to gather a wealth of data from these two celestial bodies. Dawn arrived at the first stop in its journey, the asteroid Vesta, in June 2011 and recently departed for Ceres this...

Vesta May Hold The Secret To Youth

Lee Rannals for redOrbit.com - Your Universe Online NASA's Dawn spacecraft has revealed data that shows protoplanet Vesta is continually stirring its outermost layer. The data shows that a common form of weathering that affects many airless bodies like Vesta in the inner solar system helps to keep them looking younger by not aging the outermost layer. Findings described in an upcoming issue of the journal Nature show that data indicates that carbon-rich asteroids have been...

Meteorite Shows Vesta Once Had Active Dynamo
2012-10-12 15:56:02

Lee Rannals for redOrbit.com — Your Universe Online Scientists have determined that the second-most-massive asteroid in the solar system may have once had an active dynamo. A meteorite found in Antarctica believed to be from Vesta holds clues to the asteroid once harboring a molten, swirling mass of conducting fluid generating a magnetic field, or dynamo. Scientists suspect that the composition of asteroids offer information about the diversity of planetary bodies within the...

Vesta Has Planet-Like Faults
2012-09-27 12:35:00

Lee Rannals for redOrbit.com - Your Universe Online New research reinforces the idea that the asteroid Vesta may actually have more of a history to it than just being a floating space rock. Scientists analyzed data taken by NASA's Dawn spacecraft and found that the enormous troughs that reach across the asteroid may be faults that formed when another asteroid ran into Vesta's south pole. This could indicate that Vesta has a layered interior, a quality shared by planets and large moons....

Water May Have Been Deposited On Vesta Asteroid Long Ago
2012-09-26 14:42:05

Lee Rannals for redOrbit.com — Your Universe Online Astronomers suggest that water may have been delivered to Vesta through a build-up of small particles during an epoch when the Solar System was rich in dust. The team presented their research at the European Planetary Science Congress in Madrid on Wednesday, offering up a radically different hypothesis from the way in which hydrous materials are deposited on other cosmic objects. Using data from NASA's Dawn mission, the team...

NASA Releases Last Images Of Dawn Spacecraft Visit With Vesta Asteroid
2012-09-12 14:31:54

April Flowers for redOrbit.com - Your Universe Online As NASA's Dawn mission spacecraft speeds away from the giant asteroid Vesta, mission control has released two parting views using images that were among the last taken by Dawn. One set of images is a color-coded relief map of Vesta's northern hemisphere, from the pole to the equator. It incorporates images taken as Dawn began to creep over the high northern latitudes of Vesta. These were dark when Dawn arrived in June 2011. The...

Dawn Departs Giant Asteroid Vesta

[ Watch the Video: Dawn's Greatest Hits at Vesta ] April Flowers for redOrbit.com - Your Universe Online NASA's Dawn spacecraft has escaped the gravitational pull of the giant asteroid Vesta and is on its way to the dwarf planet Ceres. The Dawn mission, supposed to last nearly a decade, has been on a journey to study Vesta and Ceres, celestial bodies believed to have accreted early in the history of the solar system. Both speak to conditions and processes present in the early...

Vesta Gets Ready For Journey To Ceres
2012-08-31 09:33:59

Watch the Video: Dawn Spacecraft's Farewell Portrait of Giant Asteroid Vesta Lee Rannals for redOrbit.com - Your Universe Online The Dawn spacecraft will be departing from asteroid Vesta on September 4 and will head out on a two-and-a-half-year journey towards the dwarf planet Ceres. The spacecraft arrived at Vesta in July 2011 after launching in 2007 on a 3-billion-mile journey towards the asteroid belt. NASA said Dawn will be reaching Ceres in early 2014. Dawn will spiral away...
