Latest Planetary defense Stories
Researchers at the University of Tennessee at Knoxville have made a novel discovery that may potentially protect the world from future collisions with asteroids.
In the 2020s, NASA will test new technologies to capture an asteroid and direct it to a stable orbit around the moon. Asteroids are being monitored in search of a candidate for the Asteroid Redirect Mission (ARM).
NASA, astronomers and scientists search the sky continually for near-Earth asteroids. Now, with the launch of Asteroid Zoo, the general public can assist in the search for undiscovered NEAs.
Proposed studies for NASA’s missions to capture and redirect an asteroid are set to kick off in July. The space agency said these studies should inform not only the future asteroid mission, but also future missions to Mars.
It’s been a busy year around the sun for NASA’s Asteroid Grand Challenge.
WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts
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.
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.
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.
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.
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...
