NASA Warns Lawmakers More Funding Needed To Protect Earth From Doomsday Asteroids
2013-03-20 09:23:02

Lawrence LeBlond for redOrbit.com - Your Universe Online The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.” That is unless, of course, the government can do more now to ensure...

Asteroid 2013 ET Captured By Deep Space Network
2013-03-20 08:50:01

April Flowers for redOrbit.com - Your Universe Online On March 10, 2013, NASA scientists obtained a sequence of radar images of asteroid 2013 ET using the 230-foot Deep Space Network antenna at Goldstone, California. At the time the images were captured, the asteroid was about 693,000 miles from Earth, or approximately 2.9 lunar distances. The asteroid is irregularly shaped and at least 130 feet wide according to the radar imagery. The scientific team, led by Marina Brozovic and Lance...

Passing Asteroid Will Be Broadcast Live By SLOOH Today
2013-03-09 12:02:37

Lee Rannals for redOrbit.com — Your Universe Online An asteroid about the size of a city block will be making its way past Earth later today, and Slooh plans on giving the world access to its tools to view the near-Earth object (NEO). Slooh, a leader in live, celestial event programming, said in a statement earlier this week that it will be broadcasting the asteroid 2013 ET on Saturday (Mar 9) as the it passes by Earth at about 2.5 times the Moon's distance from us. 2013 ET was...

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...

Asteroid Mission Targets Didymos In 2022
2013-02-23 05:53:38

redOrbit Staff & Wire Reports - Your Universe Online In the wake of the recent meteor explosion above Russia, the European Space Agency (ESA) has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA). The AIDA mission, which is a joint project headed up by European and American astronomers, will attempt to intercept asteroid Didymos, which the ESA says is a “binary,” featuring two asteroids — one approximately 800...

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...

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 Explosion Over Cuba One Day After Russian Event
2013-02-18 07:56:43

Lawrence LeBlond for redOrbit.com - Your Universe Online Just one day after a spectacular meteor exploded over Russian skies, shattering windows and injuring more than a 1,200 people, Cubans were treated to a similar event, albeit on a much smaller scale. Many of Cuba´s citizens watched in wonderment as a small fireball soared across the early evening skies on Friday before exploding. Startled residents described seeing the bright light in the sky just seconds before a thunderous...

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...

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...

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...
