The U.S. space agency says its Dawn spacecraft has re-ignited its ion propulsion system, continuing its eight-year mission to explore the asteroid belt. Mission controllers at the National Aeronautics and Space Administration's Jet Propulsion Laboratory in Pasadena, Calif., said they received a transmission from the Dawn spacecraft confirming the re-ignition. During the eight years Dawn's three ion engines will accumulate 2,000 days of operation. The spacecraft's mission includes...

Launched in September of 2007, and propelled by any one of a trio of hyper-efficient ion engines, NASA's Dawn spacecraft passed the orbit of Mars last summer. At that time, the asteroid belt (where Dawn's two targets, asteroid Vesta and the dwarf planet Ceres reside), had never been closer. In early July the spacecraft began to lose altitude, falling back towards the inner solar system. Then on October 31, 2008, after 270 days of almost continuous thrusting, the ion drive turned off. "Not...

NASA's Dawn spacecraft shut down its ion propulsion system today as scheduled. The spacecraft is now gliding toward a Mars flyby in February of next year.  "Dawn has completed the thrusting it needs to use Mars for a gravity assist to help get us to Vesta," said Marc Rayman, Dawn's chief engineer, of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Dawn will now coast in its orbit around the sun for the next half a year before we again fire up the ion propulsion system to continue...

There are hundreds of thousands of asteroids circling our sun, all so-called "minor planets" left over from the formation of the solar system. Much about them remains mysterious. Solving these mysteries could shed light on the past, present and future of cosmic impacts on Earth. Among the puzzles: Missing asteroids There should be far more asteroids that resemble Vesta, the second largest body in the asteroid belt. The outermost layers of Vesta are composed mostly of basaltic rock—the...

Their infiltration began - like so many other infiltrations - with a tell-tale contrail of smoke and flame creating a supersonic slash across the afternoon sky. But this time they would not go unnoticed. This time, two Australian station workers, just going about their job, opening a gate to a boundary fence, witnessed their arrival. The eyewitnesses later said they observed a "fireball with sparks coming off," streaking from the south to the north, make its descent into a hummock of spinifex...

NASA's Dawn spacecraft successfully completed the first test of its ion propulsion system over the weekend. The system is vital to the success of Dawn's 8-year, 1.6 billion-kilometer (3-billion-mile) journey to asteroid Vesta and dwarf planet Ceres. "Dawn is our baby and over the weekend it took some of its first steps," said Dawn project manager Keyur Patel of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "We have two months more checkout and characterization remaining before Dawn is...

CAPE CANAVERAL, Fla. - NASA's Dawn spacecraft rocketed away Thursday toward an unprecedented double encounter in the asteroid belt. Scientists hope the mission sheds light on the early solar system by exploring the two largest bodies in the belt between Mars and Jupiter: an asteroid named Vesta and a dwarf planet the size of Texas named Ceres. Dawn's mission is the world's first attempt to journey to a celestial body and orbit it, then travel to another and circle it as well. Ion-propulsion...

CAPE CANAVERAL, Fla. -- Launch and flight teams are in final preparations for the planned Sept. 27 liftoff from Pad 17-B at Cape Canaveral Air Force Station, Fla., of NASA's Dawn mission. The Dawn spacecraft will venture into the heart of the asteroid belt, where it will document in exceptional detail the mammoth rocky asteroid Vesta, and then, the even bigger icy dwarf planet Ceres. "If you live in the Bahamas this is one time you can tell your neighbor, with a straight face, that Dawn...

Some spacecraft achieve greatness, And some have greatness thrust from them. If you drive a car - and you know who you are - you have invariably come upon the dreaded dilemma of refueling. When the needle on your gas gauge wavers over the unseemly 'E,' you have to ask yourself one question - Do I stop at the next gas station or press on, hoping for a fuel oasis somewhere down the road? But what if you need to motor somewhere three billion-plus miles off the beaten path - somewhere where...
