Astronomers Find Near-Earth Encounters Leave Asteroids Pale Manoa HI (SPX) Jan 28, 2010 
Humans may be justifiably nervous when an asteroid passes very close to Earth, but a new study has found that the encounter leaves the asteroid pale and shaken as well.
UH Manoa astronomers Schelte Bus and Alan Tokunaga are members of an international team who set out to understand why some asteroids have colors different from those of others.
In particular, they wanted to know why i ... read moreThe First Of Many Asteroid Finds For WISE 
Pasadena CA (JPL) Jan 25, 2010NASA's Wide-field Infrared Survey Explorer, or WISE, has spotted its first never-before-seen near-Earth asteroid, the first of hundreds it is expected to find during its mission to map the whole sky in infrared light. The near-Earth object, designated 2010 AB78, was discovered by WISE Jan. 12. After the mission's sophisticated software picked out the moving object against a background of s ... more

Dangerous Asteroid Safely Flies Past Earth
Moscow, Russia (RIA Novosti) Jan 14, 2010An asteroid named 2010 AL30 whose unusual orbit frightened astronomers two days ago safely flew past Earth at a distance of 130,000 km (80,796 miles) on Wednesday. The asteroid some 10-15 meters long with parameters similar to a man-made object was discovered by the LINEAR survey of MIT's Lincoln Laboratories last Sunday. "The asteroid posed no danger anyway," said astronomer Leonid ... more Rosetta's OSIRIS Cameras Reveal The Nature Of Asteroid Steins 
Paris, France (ESA) Jan 13, 2010Close-up images of asteroid (2867) Steins, obtained with the OSIRIS cameras on Rosetta, have provided extensive new measurements of the physical properties of this main-belt asteroid. Steins is revealed to be a loosely-bound 'rubble pile' whose diamond shape has been honed by the YORP effect. This is the first time this effect has been seen in a main-belt asteroid. The results are reported by H. Uwe Keller and colleagues in the 8 January issue of Science magazine. ... more Rohrabacher Suggests Partnership With Russia On Asteroid Interception Project 
Washington DC (SPX) Jan 08, 2010Rep. Dana Rohrabacher (R-CA) has sent a letter to Anatoly Perminov, head of the Russian Space Agency, praising Russia's decision to set up a mission to alter the path of an asteroid on a potential collision course with Earth. The impetus for such a project stems from the current trajectory of Asteroid Apophis, scheduled to makes its first pass around Earth in the year 2029, close enough to ... more Hubble Sees Suspected Asteroid Collision 
Huntsville AL (SPX) Feb 03, 2010NASA's Hubble Space Telescope has observed a mysterious X-shaped debris pattern and trailing streamers of dust that suggest a head-on collision between two asteroids. Astronomers have long thought that the asteroid belt is being ground down through collisions, but such a smashup has never been seen before. The object, called P/2010 A2, was discovered by the Lincoln Near-Earth Asteroid Rese ... more |

Rosetta Bound For Outer Solar System After Final Earth Swingby
Paris, France (ESA) Nov 16, 2009Mission controllers have confirmed that ESA's comet chaser Rosetta swung by Earth as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. Rosetta passed over the ocean, just South of the Indonesian island of Java, at exactly 08:45:40 CET, at a speed of 13.34 km/s with respect to Earth at an altitu ... more Asteroid Explorer "HAYABUSA" Ion Engine Anomaly 
Tokyo, Japan (SPX) Nov 12, 2009On November 4th (Wed., Japan Standard Time), the Japan Aerospace Exploration Agency identified that one of the main ion engines (Thruster D) aboard the Asteroid Explorer "HAYABUSA" had autonomously stopped detecting a high neutralizer voltage owing to degradation. The HAYABUSA was in the second propulsion period during its return cruise back to the Earth in June 2010. Since the anomaly was ... more Rosetta's Observations During The Third Earth Swingby 
Paris, France (ESA) Nov 12, 2009Rosetta's third Earth swingby on 13 November 2009 provides an important opportunity to obtain calibration measurements for the science instruments and to perform science observations of both the Earth and the Moon from a unique vantage point. Rosetta is currently on its inbound trajectory towards Earth for the mission's final gravity assist manoeuvre. On 13 November, at about 7:46 UT, the ... more Follow Rosetta's Final Earth Boost
Paris, France (ESA) Nov 05, 2009ESA's comet chaser Rosetta will swing by Earth for the last time on 13 November to pick up energy and begin the final leg of its 10-year journey to comet 67P/Churyumov-Gerasimenko. ESA's European Space Operations Centre will host a media briefing on that day. This will be the third Earth swingby, the last of Rosetta's four planetary gravity assists. Closest approach to Earth is expected at ... more |
