On Wednesday, navigators and mission controllers for NASA's EPOXI mission watched their computer screens as 23.6 million kilometers (14.7 million miles) away, their spacecraft successfully performed its 20th trajectory correction maneuver. The maneuver refined the spacecraft's orbit, setting the stage for its flyby of comet Hartley 2 on Nov. 4. Time of closest approach to the comet was expected to be about 10: 02 a.m. EDT (7:02 a.m. PDT). Today's trajectory correction maneuver began at 2 p.m....

TEMPE, Ariz., Sept. 20 /PRNewswire/ -- KinetX, Inc., a Tempe, Arizona firm providing innovative engineering, software and hardware solutions to a wide variety of industries, hosted a conference celebrating the 25th anniversary of the first comet encounter by a robotic spacecraft. That first encounter happened on September 11, 1985 when the ISEE-3/ICE spacecraft's ongoing mission at a Sun-Earth libration was interrupted to target it to intercept the path of the comet Giacobini-Zinner. This...

On Sunday, Sept. 5, NASA's Deep Impact spacecraft beamed down the first of more than 64,000 images it's expected to take of Comet Hartley 2. The spacecraft, now on an extended mission known as EPOXI, has an appointment with the comet on Nov. 4, 2010. It will use all three of the spacecraft's instruments (two telescopes with digital color cameras and an infrared spectrometer) to scrutinize Hartley 2 for more than two months. "Like any tourist who can't wait to get to a destination, we have...

NASA's Deep Impact/EPOXI spacecraft flew past Earth Sunday (June 27) at approximately 3:03 p.m. Pacific time (6:03 p.m. Eastern time), as planned. The spacecraft is now on its way to its appointment with comet Hartley 2 this fall. The members of the EPOXI team at NASA's Jet Propulsion Laboratory in Pasadena, Calif., are currently working with data returned from the flyby to refine the spacecraft trajectory estimates. EPOXI is an extended mission of the Deep Impact spacecraft. Its name is...

NASA's Deep Impact/EPOXI spacecraft will fly past Earth this Sunday (June 27). Mission navigators have tailored this trajectory so the spacecraft can "hitch a ride" on Earth's gravity field, which will help propel the mission toward its appointment with comet Hartley 2 this fall. At time of closest approach to Earth, the spacecraft will be about 30,400 kilometers (18,900 miles) above the South Atlantic. "Earth is a great place to pick up orbital velocity," said Tim Larson, the EPOXI project...

NASA's Deep Impact/Epoxi spacecraft has successfully performed a trajectory correction maneuver to refine its orbit prior to an upcoming Earth flyby June 27. The maneuver, along with the Earth flyby, will place the spacecraft on a trajectory to fly past comet Hartley 2 on Nov. 4. The maneuver began at 2 p.m. EST (11 a.m. PST) today, when the spacecraft fired its engines for 11.3 seconds. While the burn changed the spacecraft's velocity by only 0.1 meters per second (less than a quarter mile...

DENVER, Feb. 18 /PRNewswire/ -- NASA's Stardust-NExT (New Exploration of Tempel) spacecraft fired its engines for 22 minutes 53 seconds on Feb. 17 to purposely delay its arrival at comet Tempel 1 by 8 hours 21 minutes. In one year, the Lockheed Martin- (NYSE: LMT) built spacecraft will still fly by the comet on Feb. 14, 2011, Valentines' Day, but the encounter time will now be 8:42 p.m. PT. The low-cost Discovery Program Mission of Opportunity will expand the investigation of comet...

In two new videos from NASA's Deep Impact spacecraft, bright flashes of light known as sun glints act as beacons signaling large bodies of water on Earth. These observations give scientists a way to pick out planets beyond our solar system (extrasolar planets) that are likely to have expanses of liquid, and so stand a better chance of having life. These sun glints are like sunshine glancing off the hood of a car. We can see them reflecting off a smooth surface when we are positioned in just...

PASADENA, Calif., Sept. 29 /PRNewswire-FirstCall/ -- Alliant Techsystems (NYSE: ATK) played a critical role in the design and engineering of the Moon Mineralogy Mapper (M3) instrument which helped NASA confirm the existence of water molecules on the lunar surface. The M3 instrument on board the Chandrayaan-1 spacecraft, along with 2 other NASA spacecraft, Cassini and Epoxi, has contributed to the confirmation of water molecules on the moon. ATK's contribution to M3 included the...

COLLEGE PARK, Md., Sept. 25 /PRNewswire-USNewswire/ -- New data from the Deep Impact spacecraft and the Moon Mineralogy Mapper (M3), an instrument aboard India's recently ended Chandrayaan-1 spacecraft, provide, for the first time, clear evidence that water exists on the surface of the Moon. "The Deep Impact observations of the Moon not only unequivocally confirm the presence of OH/H2O on the lunar surface, but also reveal that the entire lunar surface is hydrated during at least some...
