Asteroid Challenge Issued By NASA
2013-06-19 05:44:49

redOrbit Staff & Wire Reports - Your Universe Online NASA is looking for asteroids, and is seeking help from citizen scientists to locate the dangerous space rocks and reduce the potential threats they may pose to human populations. "NASA already is working to find asteroids that might be a threat to our planet, and while we have found 95 percent of the large asteroids near the Earth's orbit, we need to find all those that might be a threat to Earth," said NASA Deputy Administrator...

NASA Traces Evolution Of Asteroid Families
2013-05-30 11:54:27

Brett Smith for redOrbit.com - Your Universe Online Using the orbiting Wide-field Infrared Survey Explorer (WISE), NASA scientists have been able to identify and categorize 28 new asteroid families found in the main belt between Mars and Jupiter, the space agency announced. Infrared snapshots from the asteroid-hunting section of the survey, called NEOWISE, allowed scientists to spot and sort thousands of previously hidden and uncategorized asteroids into families. "NEOWISE has given...

Monitoring Elusive Collisions In Space
2013-04-24 06:09:40

April Flowers for redOrbit.com - Your Universe Online Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts. New research from the University of California, Los Angeles, has devised a method to monitor these types of collisions in interplanetary space. The team used a new method to determine the mass of...

Human Asteroid Exploration: The Long And Storied Path
2013-04-17 10:43:01

NASA Within NASA´s new FY2014 budget proposal lies a project known as the Asteroid Retrieval and Utilization Mission. This project would be the first to capture a small near-Earth asteroid and safely redirect it to a lunar orbit so that astronauts can visit and explore it. Such a mission would expand scientific knowledge of the origins of both humanity and the universe. The goal of asteroid retrieval is not a new endeavor for NASA. In fact, the idea dates to the earliest days of...

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...

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...

Scientists Propose System For Eliminating Threat Of Asteroids, Meteors
2013-02-15 13:01:40

Brett Smith for redOrbit.com - Your Universe Online A pair of California scientists unveiled a proposal this week for a system that could eliminate threatening asteroids or meteors, just as a meteor explodes over Russia and an asteroid grazes past Earth within a 24-hour span. Several online videos showing a meteorite streaking, then exploding over Russia, and reports describing the asteroid 2012 DA14 serve as timely reminders of just how crucial the system, dubbed DE-STAR, could be....

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

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...
