Earth Gravity Altered By 2011 Japan Quake, According To GOCE Data
2013-12-03 13:50:29

[ Watch the Video: Earth's Gravity Was Affected By 2011 Japanese Quake ] Lee Rannals for redOrbit.com - Your Universe Online Japan’s devastating earthquake in 2011 left its mark on more than the town of Fukushima. The European Space Agency (ESA) says that it had an impact on Earth’s gravity as well. Scientists used data from ESA’s GOCE satellite to show the effects of the 9.0 earthquake that struck east of Japan’s Honshu Island on March 11, 2011. The strength of gravity...

ESA's Defunct GOCE Satellite Expected To Fall Back To Earth Soon
2013-11-07 10:14:38

redOrbit Staff & Wire Reports - Your Universe Online Beware of falling satellites this weekend, as a European Space Agency (ESA) probe that had been mapping the planet’s gravitational field is expected to plummet back to Earth within the next few days. The Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite was launched in 2009, and managed to remain in low-orbit some 160 miles above the Earth thanks to its ion engine, UPI reported on Wednesday. However,...

Lasting Propulsion And High Speeds For Deep Space Missions Provided by NEXT

[ Watch The Video - Gridded Ion Thruster ] NASA Ion propulsion used to exist only in the imagination of science fiction writers. But after years of research and development NASA is poised to equip some of its most important deep space missions with ion engines that can nudge spacecraft using charged particles accelerated to blistering speeds of up to 90,000 miles per hour.  And in the vastness of space, those engines need to push continuously for years. NASA’s Evolutionary Xenon...

NASA Administrator Talks Asteroids During Visit At JPL
2013-05-24 09:57:14

NASA's Jet Propulsion Laboratory NASA Administrator Charles Bolden met with members of the asteroid initiative team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., today. Later, Bolden and some team members spoke with media inside a JPL lab where advanced technology propulsion systems are built and tested, like the type that will be used for the asteroid initiative. JPL and NASA's Glenn Research Center in Cleveland are developing the ion thruster jointly. The initiative is a...

To Mars In A Month With The Help Of Nuclear Fusion
2013-04-09 19:22:32

Michael Harper for redOrbit.com — Your Universe Online There are many who would like to one day go to Mars. This list of willing candidates likely dries up when asked to dedicate a total of four years to the trip. The Inspiration Mars Foundation, on the other hand, believes they can shoot a couple around the Red Planet and back again in just over 500 days. Now, researchers at the University of Washington aim to make the trip in even less time — somewhere around 30 days, to...

Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory, in Pasadena, Calif., has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields...

GOCE’s Second Mission To Improve Gravity Map
2012-11-16 12:22:31

ESA ESA´s GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) has been orbiting Earth since March 2009, reaching its ambitious objective to map our planet´s gravity with unrivalled precision. Although the planned mission has been completed, the fuel consumption was much lower than anticipated because...

NASA Releases Last Images Of Dawn Spacecraft Visit With Vesta Asteroid
2012-09-12 14:31:54

April Flowers for redOrbit.com - Your Universe Online As NASA's Dawn mission spacecraft speeds away from the giant asteroid Vesta, mission control has released two parting views using images that were among the last taken by Dawn. One set of images is a color-coded relief map of Vesta's northern hemisphere, from the pole to the equator. It incorporates images taken as Dawn began to creep over the high northern latitudes of Vesta. These were dark when Dawn arrived in June 2011. The...
