NEWTON, N.C., Jan. 19, 2011 /PRNewswire/ -- General Dynamics SATCOM Technologies received a $40.7 million contract from the National Aeronautics and Space Administration's (NASA) Jet Propulsion Laboratory (JPL) to build two additional 34-meter (112-foot wide) beam waveguide antennas as part of NASA's modernization and transformation plan to continue scientific studies of the Earth as well as explore distant bodies in the solar system. The new antennas will be located at the Deep Space...

Deep in the heart of the asteroid belt, on its way to the first of the belt's two most massive inhabitants, NASA's ion-propelled Dawn spacecraft has eclipsed the record for velocity change produced by a spacecraft's engines. The previous standard-bearer for velocity change, NASA's Deep Space 1, also impelled by ion propulsion, was the first interplanetary spacecraft to use this technology. The Deep Space 1 record fell on Saturday, June 5, when the Dawn spacecraft's accumulated acceleration...

Researchers at Hampshire defense and security firm Qinetiq are currently testing ion thrusters, which they hope will one day bring spacecraft to the planets through solar energy.The ion engines create thrust by the acceleration if ions by electromagnetic forces. They make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current.This is used to accelerate a beam of ions of xenon away from the spacecraft, thereby providing...

A former comet-slamming spacecraft will swing by Earth on New Year's Eve before starting a two-and-a-half-year journey to Comet Hartley 2. Deep Impact will first spend six months using the larger of its two telescopes to search for Earth-sized planets around five candidate stars. The second part of its extended mission involves a flyby of Hartley 2 that allows close observations of the comet's features. "It's exciting that we can send the Deep Impact spacecraft on a new mission...

"Beep"¦ beep"¦ beep...." That's the sound that marked the beginning of the Space Age fifty years ago. It was a simple radio tone transmitted by the first satellite, Sputnik 1, as it orbited Earth in October 1957. Since then communication with spacecraft has advanced tremendously. Yet a modern probe on the way to the edge of the solar system is using Sputnik-like tones to send messages back to Earth. Why the retro technology? It solves a modern problem: multiplication. Sputnik...

BERLIN -- Europe's first mission to the moon got a scare, but ground controllers made a last-minute course correction early Saturday that kept the craft from hitting the surface earlier than planned. Mission officials said they raised the low point of the SMART-1 spacecraft about 2,000 feet by using its positioning thrusters to avoid the almost mile-high rim of a moon crater. The maneuver began late Friday night from the European Space Agency's mission control in Darmstadt and was completed...

NASA -- We are a curious species with amazing capacities to imagine and dream. We wonder about what we cannot see, are fascinated by what we do not know and are driven to explore. In keeping with our continuous quest for knowledge, President George W. Bush announced a new plan for NASA in Jan. 2004. A renewed focus on space exploration, he explained, would strengthen our leadership in the world, improve our economy and enhance the quality of our lives. The Vision for Space Exploration calls...

NASA -- Whether they're set "a long time ago in a galaxy far, far away" or somewhere in our solar system centuries from now, Hollywood blockbusters often take us to new worlds in extraordinary spacecraft. They can travel faster than the speed of light, create their own onboard gravity and tap into endless supplies of power. But just how realistic are these science-fiction marvels? Throughout history, the grand visions of science fiction have inspired scientific breakthroughs. In the 1800s,...

It's called Dawn, and in a little more than a year, this spacecraft will blast off from Florida, bound for two separate asteroids: Vesta and Ceres. Visiting the two most massive asteroids in our Solar System will be an ambitious undertaking; maybe one of the most difficult and dangerous orbital missions attempted. Dawn will bring a suite of scientific instruments to these two asteroids and serve as a time machine to help scientists understand what our Solar System looked like 4.6 billion...

Word of the Day
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
