NASA Asteroid Mining Mission
2013-08-09 12:28:02

[ Watch The Video: OSIRIS-REx Investigates Asteroid Bennu ] Brett Smith for redOrbit.com - Your Universe Online NASA announced yesterday that it will be launching a spacecraft in 2016 with the intent of laying the groundwork for future expeditions to mine asteroids. The space agency added that the mission – dubbed the Origins, Spectral Interpretation, Resource Identification, Security and Regolith Explorer (OSIRIS- REx) – is scheduled to visit the asteroid Bennu and enable...

Asteroid Spin May Reveal Clues About Its Future Orbital Path
2013-02-12 11:46:49

April Flowers for redOrbit.com - Your Universe Online On February 15, astronomers will have an exciting opportunity with a record-setting close approach of an asteroid.  The research team, using the National Radio Astronomy Observatory (NRAO) and NASA telescopes, will gain a key clue that will help predict the future of this natural cosmic orbiter. Discovered just a year ago, the 150-foot-wide asteroid, called 2012 DA14, will pass only 17,200 miles from the Earth on Friday, which...

OSIRIS-Rex To Study Asteroid Yarkovsky Effect
2013-02-08 18:46:31

Lee Rannals for redOrbit.com — Your Universe Online NASA will be launching a new mission in 2016 to help estimate what kind of impact an asteroid would make if it struck Earth. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, and Regolith Explorer) mission will travel to a potentially hazardous asteroid (PHA), and make measurements of the Yarkovsky effect. This effect is a push on an asteroid that happens when it is warmed up by the sun and...

The work of a University of Tennessee, Knoxville, professor has helped reveal a rare orbital shift and the density of an asteroid that will pass close to Earth. Josh Emery, assistant professor of earth and planetary sciences, and the team of the NASA asteroid sample return mission called OSIRIS-REx have measured the weight and orbit of 1999 RQ36. They have found the asteroid has a low density and its orbit has drifted roughly 100 miles in the last twelve years. This deviation is...

Scientist Guesses Asteroid's Weight, Millions Of Miles Away
2012-05-25 11:18:04

Lee Rannals for RedOrbit.com A NASA scientist would be a shoe-in at any state or county fair if hosting the "guess your weight" game. Steve Chesley of JPL's Near-Earth Object Program Office has accurately determined the mass of an asteroid from millions of miles away. Chesley used data from the Goldstone Solar System Radar in the California desert, along with the orbiting Spitzer Space Telescope and the Arecibo Observatory in Puerto Rico, to make his findings. He said he first...

Scientists have discovered that a potentially hazardous asteroid might collide with Earth in 2182. The scientists used two mathematical models in order to determine the chance of impact. "The total impact probability of asteroid '(101955) 1999 RQ36' can be estimated in 0.00092 "“approximately one-in-a-thousand chance-, but what is most surprising is that over half of this chance (0.00054) corresponds to 2182," explains to SINC María Eugenia Sansaturio, co-author of...

A menacing lump of rock and dust in space called 10195 (1999 RQ36) would barely be noticed except for two crucial facts: First, "It's a treasure trove of organic material, so it holds clues to how Earth formed and life got started," said Joseph Nuth of NASA's Goddard Space Flight Center, Greenbelt, Md. Second, it regularly crosses Earth's orbit, so it might impact us someday. Nuth is Project Scientist for the proposed OSIRIS mission, which will "return a pristine sample of the scientifically...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
