asteroid 2011 MD spitzer
2014-06-19 13:09:44

Whitney Clavin, Jet Propulsion Laboratory Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision...

WASHINGTON, June 16, 2014 /PRNewswire-USNewswire/ -- On Thursday, June 19, NASA will host a televised update on recent progress and upcoming milestones in the agency's efforts to identify, capture and relocate an asteroid, and send astronauts to take samples of it in the 2020s. The 1-2:30 p.m. EDT event will kick off a two-day virtual workshop to highlight successes and new opportunities through NASA's Asteroid Grand Challenge, which coincides with its first anniversary....

asteroid the beast

Brett Smith for redOrbit.com - Your Universe Online Last year, a massive asteroid that had gone undetected exploded over Chelyabinsk, Russia in a huge fireball and another, much bigger asteroid spotted in April is expected to buzz past Earth this weekend. While the incoming HQ124 asteroid, aka “the Beast,” is not expected to make contact with the Earth’s atmosphere, professional skywatchers will be keeping close tabs on the massive space rock nonetheless. “What’s...

Chelyabinsk Meteor Collided With Asteroid Before Hitting Earth
2014-05-26 10:02:12

Lawrence LeBlond for redOrbit.com - Your Universe Online A wealth of research has come following the Chelyabinsk meteor that exploded over Russia’s Ural Mountains on February 15, 2013. The latest study, which comes from scientists at the University of Tohoku in Japan, claims that the meteor collided with an asteroid before heading on its collision course with Earth. Analysis of a mineral called jadeite found embedded in fragments recovered after the explosion show that the parent body...

WASHINGTON, May 22, 2014 /PRNewswire-USNewswire/ -- As part of the agency's Asteroid Grand Challenge, NASA is partnering with private internet technology company Slooh to engage citizen scientists in the effort to track and characterize near-Earth asteroids (NEOs) that are potentially hazardous to human populations. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Slooh's global network of web-connected telescopes will be available for use by amateur astronomers for...

Sentinel Telescope May Help Save Us From Earth-Killing Asteroids

Lawrence LeBlond for redOrbit.com - Your Universe Online Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood. But in the modern world, are the impacts portrayed in movies like Deep Impact and Armageddon only the stuff of science fiction? The answer is likely no. Scientists continue to warn us of the dangers that lurk in the skies above us and in the past dozen or so years, no less than 26...

Small Asteroid Will Safely Pass Earth
2014-03-06 12:52:56

NASA's Jet Propulsion Laboratory An asteroid about 25 feet (8 meters) across will safely pass Earth at about 1:21 p.m. PST (4:21 p.m. EST) today, March 6, approaching us six times closer than the moon. This distance, though not unusual, is closer than the Earth flyby of a larger asteroid on Wednesday afternoon, March 5. This afternoon's flyby object, asteroid 2014 EC, was discovered on March 5 by the Catalina Sky Survey near Tucson, Ariz. Its closest-approach distance, about 38,300...

Large Asteroid Set To Pass Between Earth And Moon
2014-03-04 14:50:08

Lee Rannals for redOrbit.com - Your Universe Online An asteroid with a diameter about the size of an 80-story building is sweeping by Earth and the moon on Wednesday. Asteroid 2014 CU13 was first discovered on February 11th by Mt. Lemmon Survey. Since then, the asteroid has been viewed over 230 times, but there still remains a lack of information in trying to pinpoint the space rock’s exact orbit. Slooh will be attempting to offer up a webcast of the asteroid as it makes its...

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...
