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....

Computer Simulations Help Explore Origins Of Our Solar System
2013-02-15 10:00:41

Peter Suciu for redOrbit.com — Your Universe Online Understanding past collisions between celestial bodies, including asteroids, could help researchers better understand the origins of our Solar System. After all, it was through a series of such collisions some four and a half billion years ago that our planetary system was formed. What started as a giant dusty gas cloud combined to form increasingly large clumps, and as these collided and combined, they grew into what we now...

Planetary Resources To Join The Hunt For Asteroids
2013-02-15 05:03:47

[ Watch the Video: Asteroid 2012 DA14 To Whiz Past Earth Safely ] Lee Rannals for redOrbit.com - Your Universe Online Planetary Resources, a company aimed at mining asteroids, says that its Arkyd-100 Series of spacecraft will be assisting in the detection and characterization of potentially hazardous asteroids near Earth. About 610,000 asteroids are being tracked in the Solar System currently, which is a number that represents less than one percent of the estimated objects that orbit...

Billion Dollar Asteroid Making Close Approach To Earth
2013-02-14 10:55:10

Lee Rannals for redOrbit.com - Your Universe Online The idea to start attempting to mine asteroids has been floating around recently, but questions remain as to whether or not such a business endeavor would even be lucrative. Now, however, Deep Space Industries (DSI) claims that one particular asteroid could be worth as much as $195 billion in metals and propellant. Deep Space Industries announced this week that DA14, the asteroid making a close approach to Earth this week, could be...

Large Asteroid Will Make Earth Flyby Next Month
2013-01-29 12:55:40

[Watch Video: Record-Setting Asteroid Flyby] Lee Rannals for redOrbit.com — Your Universe Online A record-setting asteroid about the size of half a football field will be making a close flyby to Earth just after Valentine's Day. Although there is no danger of a collision, the asteroid, 2012 DA14, will still be making a record-setting close approach, according to NASA. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth," Don...

Asteroid Prospecting Fleet Announced By Deep Space Industries
2013-01-22 10:18:32

Lee Rannals for redOrbit.com - Your Universe Online Deep Space Industries (DSI) announced on Tuesday that it plans to send a fleet of asteroid-prospecting spacecraft out into the solar system. These "FireFly" spacecraft use low-cost components and get discounted delivery to space by ride-sharing on the launch of larger satellites. “This is the first commercial campaign to explore the small asteroids that pass by Earth,” Deep Space Chairman Rick Tumlinson said in a...

ESA Asteroid Deflection Missions Underway
2013-01-15 18:17:23

Lee Rannals for redOrbit.com — Your Universe Online One mission aims to take a Bruce Willis approach in the movie Armageddon, by deflecting any future asteroids that might be headed towards Earth. The European Space Agency is looking for research ideas to help guide the development of an asteroid deflection mission study. ESA is asking for concepts based on both ground- and space-based investigations that could improve the understanding of the physics of very high-speed...

Vesta Has Planet-Like Faults
2012-09-27 12:35:00

Lee Rannals for redOrbit.com - Your Universe Online New research reinforces the idea that the asteroid Vesta may actually have more of a history to it than just being a floating space rock. Scientists analyzed data taken by NASA's Dawn spacecraft and found that the enormous troughs that reach across the asteroid may be faults that formed when another asteroid ran into Vesta's south pole. This could indicate that Vesta has a layered interior, a quality shared by planets and large moons....

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...
