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...

Gravity Satellite Will Benefit Future Missions

ESA´s GOCE satellite is not only mapping Earth´s gravity with unrivalled precision, but is also revealing new insight into air density and wind in space. This additional information is expected to improve the design and operation of future Earth observation missions. Most satellites orbit Earth higher than 400 km. Lower than that and atmospheric drag causes them to slow down quickly and reenter the atmosphere prematurely. This posed a problem for the designers of the GOCE...

NASA's Dawn spacecraft is on track to begin the first extended visit to a large asteroid. The mission expects to go into orbit around Vesta on July 16 and begin gathering science data in early August. Vesta resides in the main asteroid belt and is thought to be the source of a large number of meteorites that fall to Earth. "The spacecraft is right on target," said Robert Mase, Dawn project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "We look forward to exploring this...

After 3 and a half years of thrusting silently through the void, NASA's Dawn spacecraft is on the threshold of a new world. It's deep in the asteroid belt, less than 4 months from giant asteroid Vesta. "We're closing in," says Marc Rayman, Dawn's chief engineer and mission manager. "And I'm getting more excited every day!" Dawn will enter orbit around Vesta in July 2011, becoming the first spacecraft ever to orbit a body in the asteroid belt. After conducting a detailed study of the uncharted...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
