NASA has selected 96 asteroid initiative ideas about how to protect Earth from asteroids and find a space rock for humans to explore. The list was dwindled down from more than 400 submissions the space agency received since June.
NASA announced its Wide-field Infrared Survey Explorer (WISE) will be coming out of retirement to track near-Earth objects (NEOs).
A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013.
While disaster movies are made about the looming threat of asteroids colliding with the earth, scientists are studying the space rocks for their mineral potential. Now scientists at the University of Strathclyde in the UK have identified a new category of asteroid they deem easy to capture.
NASA Deputy Administrator Lori Garver announced this week that the agency has received more than 400 responses to its request for information on its Asteroid Initiative.
For his work making the solar system's nomads of the night sky -- near-Earth objects, asteroids and comets -- tangible and compelling for millions of people, Donald K. Yeomans, the manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, has received the 2013 Carl Sagan Medal from the American Astronomical Society (AAS).
NASA said the 10,000th near-Earth object has been discovered using the Pan-STARRS-1 telescope in Hawaii.
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 Î”V (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 Î”V 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...
