NASA Asteroid Initiative
2014-02-13 07:01:17

NASA In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids. He also engaged the United Nation’s support for NASA’s mission to find, capture and redirect an asteroid to lunar orbit, and then send humans to explore it by 2025. Following Bolden’s presentation, Mazlan Othman, director of the U.N. Office for Outer...

Using Space Probes To Deflect Asteroids From Earth Trajectories
2013-10-23 14:17:04

[ Watch the Video: Space Probes Could One Day Help Deflect Asteroids ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are conducting experiments to figure out how space probes could be used to deflect potentially hazardous asteroids. Researchers at Fraunhofer Institute for High-Speed Dynamics have begun initial experiments to verify the possibility of deflecting asteroids by impacting them with heavy masses at high speeds. They said the principle behind their research...

Asteroid Tracking Sensor Passes Key Test
2013-04-16 07:07:54

April Flowers for redOrbit.com - Your Universe Online A critical design test for an infrared sensor that could improve NASA's future ability to detect and track asteroids and comets has been passed. The Near Earth Object Camera's (NEOCam) performance in an environment that mimicked the temperatures and pressures of deep space were assessed by the test. NEOCam will be the key instrument for a proposed new asteroid-hunting space-based telescope for which design and capability details have...

Chinese Probe Gets Up Close And Personal With Asteroid 4179 Toutatis
2012-12-17 08:38:30

[Watch Video: Surface Features of Asteroid Toutatis Revealed By Radar] Lawrence LeBlond for redOrbit.com - Your Universe Online An asteroid by the name of 4179 Toutatis passed close enough to Earth last week that China´s Chang´e-2 probe was able to fly by the object, named for the Celtic deity Teutates by Christian Pollas in 1989, and snap some photos. The asteroid reportedly passed within 2 miles of the probe before swinging back out in Jupiter´s neighborhood....

Potentially Hazardous Asteroid Passing Close To Earth Tonight
2012-12-11 15:23:13

Lee Rannals for redOrbit.com — Your Universe Online Potentially Hazardous Asteroid, 4179 Toutatis, will be making a close approach of Earth this week, just in time to give "world ending" theorists something to talk about. The asteroid has an estimated diameter of over 3 miles, which is about half the size of the asteroid that wiped out the dinosaurs. Some believe that the Mayan calendar predicts the world will be ending this year on December 21 due to an asteroid striking...

Lost Asteroid Rediscovered By Amateur Astronomer
2012-10-13 05:05:52

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) reports that it has rediscovered an asteroid that was once lost through the agency's space hazards program. Potentially Hazardous Asteroid 2008SE85 was first discovered back in September 2008 by the Catalina Sky Survey, and was observed by a few observatories the following month. However, no one since then has observed the object, and predictions for its current position had become so inaccurate that...

Lee Rannals for redOrbit.com — Your Universe Online In relative terms, the Earth is about to escape another asteroid impact on Thursday by the hair on its chin. Although it's not like the 14-story sized asteroid is going to be nearing so close to Earth that you will be getting a prime view of in it your backyard, it will be about 7.5 times the Moon's distance from our planet. The asteroid, which is between 625 and 1,400 feet across, is close enough to Earth to be classified a...

WASHINGTON, June 15, 2012 /PRNewswire-USNewswire/ -- Researchers anticipate that asteroid 2011 AG5, discovered in January 2011, will fly safely past and not impact Earth in 2040. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Current findings and analysis data were reported at a May 29 workshop at NASA's Goddard Space Flight Center in Greenbelt, Md., attended by scientists and engineers from around the world. Discussions focused on observations of potentially hazardous...

City-Block Sized Asteroid Whizzing By Earth Tonight
2012-06-14 13:52:39

Lee Rannals for redOrbit.com A huge asteroid the size of a city block will be skimming by Earth on Thursday night at 8:00 eastern time. The giant space rock is about 1,650-feet wide and is big enough to qualify as a potentially hazardous asteroid.  However, experts stress there is no chance of a collision, and it will be passing Earth at a safe 3 million miles away. Astronomers in Australia discovered the asteroid 2012 LZ1 on Sunday night, and found that the object is going to...

NASA Keeping An Eye Out For Dangerous Asteroids
2012-05-17 11:24:34

NASA has just received observations from its WISE (or Wide-field Infrared Survey Explorer) mission, giving them the best assessment thus far of how many PHAs (potentially hazardous asteroids) are floating around in our solar system. Now, the team at NASA can count these PHAs, discover their origins and predict what kind of harm they may pose to Earth. According to a report from NASA´s Jet Propulsion Laboratory in Pasadena, these PHAs are a subset of a larger group of near-Earth...
