Lee Rannals for redOrbit.com - Your Universe Online Mars may be helping to shape the surface of some near-Earth asteroids, according to a new study published in the journal Icarus. Richard Binzel, a professor of planetary sciences at MIT, found in 2010 that asteroids that venture outside of the main belt in our solar system could be experiencing “asteroid quakes” as they come too close to Earth’s gravity. These quakes shift surface grains, exposing fresh grains underneath, which helps...

New Analysis Chelyabinsk Meteor

Brett Smith for redOrbit.com - Your Universe Online A series of recently released papers dealing with the meteor that exploded over Chelyabinsk, Russia, in February, brought forth two startling conclusions: the damage could have been much worse, and these types of events could be much more common than previously thought. According to one of the reports published in the journal Science, the meteor over Chelyabinsk created a 500-kiloton explosion about 20 miles above the surface that...

Lawrence LeBlond for redOrbit.com - Your Universe Online Environmental satellites tasked with studying Earth’s weather accidentally captured data of an extraterrestrial kind this past February. Scientists studying the Chelyabinsk meteor that blazed a trail over Russia’s Ural Mountains on February 15, 2013 have been able to track the trajectory of the fireball using these weather satellites. Publishing their work in the Proceedings of the National Academy of Sciences (PNAS), study...

Newly Discovered Asteroid Has Slight Chance Of Impacting Earth

[ Watch the Video: Earth Receives A Quick Visit From Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. While 4.2 million miles seems far enough away, experts said the rock, known as asteroid 2013 TV135, will have a slight chance of impacting Earth when it returns in 2032. While...

redOrbit Staff & Wire Reports - Your Universe Online When is a near-Earth asteroid not a near-Earth asteroid? When an international team of researchers discover that the object has been misidentified by the scientific community for the past three decades, and is actually a comet. The bombshell discovery was the result of an ongoing project headed up by experts from Northern Arizona University (NAU), and was presented this week at the European Planetary Science Congress 2013 in...

Close To One Hundred Ideas Selected For Possible NASA Asteroid Missions

Brett Smith for redOrbit.com - Your Universe Online NASA announced on Wednesday that one member of its fleet will be coming out of retirement to become part of a project that will eventually lead to placing humans on an asteroid. The Wide-field Infrared Survey Explorer (WISE) discovered and categorized thousands of asteroids throughout the solar system before being decommissioned in February 2011. That retirement will end in September when the orbiter reawakens with a new mission – to...

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...
