The Hunt For Near-Earth Asteroids Heats Up After 2012 EC Passes Earth
2013-03-05 06:16:21

Lawrence LeBlond for redOrbit.com - Your Universe Online An asteroid that was only discovered Saturday (Mar. 2) has made a run by Earth in the early hours of March 5, some 250,000 miles away. While the asteroid is being associated with last month´s Russian meteor in respect to its mass, the two bodies are not linked in any other way. The asteroid, 2012 EC, was detected by Arizona´s Mt. Lemmon Observatory and astronomers calculated its trajectory, confirming the object would...

NASA Says Russian Meteorite 1000 Times Larger Than Originally Estimated
2013-02-22 14:13:51

Lawrence LeBlond for redOrbit.com - Your Universe Online Initial reports put last Friday´s (Feb 15) Chebarkul meteorite that exploded over Russia´s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons–1,000 times larger than the estimated size reported by the Russian Academy of Sciences (RAS). “My guess is that someone eyeballed the videos and made an educated guess,” said...

Radar Movie Of Asteroid 2012 DA14 Released By NASA
2013-02-20 10:59:44

NASA's Jet Propulsion Laboratory [ Watch The Video Early Radar Observations of Asteroid 2012 DA14 ] An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar. The observations were made as the asteroid was moving away from Earth. The asteroid's distance from...

Asteroid Impact In Russia: ESA Update And Assessment
2013-02-19 08:00:31

ESA The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear. ESA is carefully assessing the information as crucial input for developing the Agency´s asteroid-hunting effort. At 03:20 GMT on 15 February, a natural object entered the atmosphere and disintegrated in the skies over Chelyabinsk, Russia. Extensive video records indicate a northeast to southwest path at a shallow angle of 20° above the horizontal....

On February 15, asteroid 2012 DA14 passed extraordinarily close to the earth. Unlike the unexpected asteroid collision over Russia that day, this encounter never presented any danger but astronomers were eager to observe the event. An international team led by Nicholas Moskovitz (MIT) observed the asteroid with a number of telescopes, including the 2.1m telescope at Kitt Peak National Observatory: the accompanying video shows the asteroid as it was leaving the vicinity of the earth. As Dr....

Meteor Strikes Like Russian Event Only Occur Once Every 10 To 30 Years
2013-02-15 17:22:17

Lawrence LeBlond for redOrbit.com - Your Universe Online As reports continue to stream in through various media outlets on injuries, damages, and the science behind such events, it seems this morning´s (February 15) meteor strike in Russia´s Ural Mountains region has left a pretty big impression far and wide. At last count more than 1,200 people (at least 200 children) are believed to have been injured by the meteor, most from broken glass produced by the exploding object's...

Massive Meteor Explodes Over Russia: Buildings Damaged, Hundreds Injured
2013-02-15 08:57:01

Lawrence LeBlond for redOrbit.com - Your Universe Online A meteor streaked across Russia´s early morning skies on Friday before violently exploding, sending a rain of debris onto the Earth below. The flash and boom shattered windows and meteor particles left damage in its wake, injuring more than 900 people in the Ural Mountains region. Marina Mokvicheva, regional health minister in Chelyabinsk, the Russian city that had felt the brunt of the impact, told the Washington Post that...

Planetary Resources To Join The Hunt For Asteroids
2013-02-15 05:03:47

[ Watch the Video: Asteroid 2012 DA14 To Whiz Past Earth Safely ] Lee Rannals for redOrbit.com - Your Universe Online Planetary Resources, a company aimed at mining asteroids, says that its Arkyd-100 Series of spacecraft will be assisting in the detection and characterization of potentially hazardous asteroids near Earth. About 610,000 asteroids are being tracked in the Solar System currently, which is a number that represents less than one percent of the estimated objects that orbit...

Billion Dollar Asteroid Making Close Approach To Earth
2013-02-14 10:55:10

Lee Rannals for redOrbit.com - Your Universe Online The idea to start attempting to mine asteroids has been floating around recently, but questions remain as to whether or not such a business endeavor would even be lucrative. Now, however, Deep Space Industries (DSI) claims that one particular asteroid could be worth as much as $195 billion in metals and propellant. Deep Space Industries announced this week that DA14, the asteroid making a close approach to Earth this week, could be...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
