By Karen C. Fox, NASA's Goddard Space Flight Center On Nov. 4, 2010, NASA's EPOXI spacecraft came within 450 miles of Comet Hartley 2, a small comet not even a mile in diameter, which takes about six and a half years to orbit the sun. Designated officially as 103P/Hartley 2, the comet thus became the fifth for which scientists have collected close-up images. But the comet was also observed from another spacecraft: the Solar and Heliospheric Observer (SOHO), better known for its observations...

Karen C. Fox, NASA's Goddard Space Flight Center Whether it's a giant solar flare or a beautiful green-blue aurora, just about everything interesting in space weather happens due to a phenomenon called magnetic reconnection. Reconnection occurs when magnetic field lines cross and create a burst of energy. These bursts can be so big they're measured in megatons of TNT. Several spacecraft have already sent back tantalizing data when they happened to witness a magnetic reconnection event in...

Frank Reddy, NASA's Goddard Space Flight Center, Greenbelt, Md. Late last year, astronomers noticed an asteroid named Scheila had unexpectedly brightened, and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope showed these changes likely occurred after Scheila was struck by a much smaller asteroid. "Collisions between asteroids create rock fragments, from fine dust to huge boulders, that impact planets and their moons," said Dennis Bodewits, an...

By Karen C. Fox, NASA's Goddard Space Flight Center In March of 1611, a German medical student named Johannes Fabricius left school at Leiden in Holland carrying several of the new-fangled telescopes that were beginning to appear in the Netherlands. He was off to visit his father "“ the well-known astronomer and astrologer David Fabricius who had had a heralded career working with Europe's celebrity astronomers, Tycho Brahe and Johannes Kepler. In 1611, David Fabricius lived in Osteel,...

By Karen C. Fox, NASA's Goddard Space Flight Center Solar flares "“ they're big and they're fast. They can knock out a satellite or create a beautiful aurora. And the jury is still out on what causes these explosions. Flares, and the related coronal mass ejection, shoot energy, radiation, and magnetic fields out into space that can harm satellites or humans in space. Current observations aren't precise enough to determine whether the eruptions are driven by energy surging through the...

NASA has exercised a second one-year option with Bastion Technologies Inc. of Houston for continued services in support of the Safety and Mission Assurance Directorate at NASA's Marshall Space Flight Center in Huntsville, Ala. The extension runs through Jan. 31, 2011. The contract is a cost plus award fee with award term arrangements. The current potential value of the contract, including this $36 million contract option, is $136 million. Subsequent unexercised options and award terms extend...

Goddard Space Flight Center -- Scientists using NASA satellite data found the shape of the Earth appears to be influenced by big climate events that cause changes in the mass of water stored in oceans, continents and atmosphere. The study's principal researchers are Minkang Cheng and Byron D. Tapley, of the Center for Space Research, University of Texas at Austin. They reviewed climate events like El Niôo Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO)...

SEATTLE, Nov. 26, 2004 (PRIMEZONE) -- Andrews Space announced today that it was selected as NASA/Marshall Space Flight Center's Woman Owned Business of the Year. Andrews has also recently won several NASA contracts, including one to define a vision and architecture for human missions to the Moon and exploration of Mars including the Crew Exploration Vehicle (CEV), as well as a Small Business Innovation Research grant to design and flight-test a Variable Drag Ballute. Andrews Space is a team...
