Travel group operated by Insight Cruises. Planetary scientists study asteroids (and meteorites, which is the term for asteroids and comet pieces that have fallen to Earth) because they are Nike Air Jordan 6 Retro Black rocks left over from the formation of the Solar System's planets and can carry complex organic molecules. A great number of these fascinating time capsules also could strike and seriously damage Earth and its environment. Bennu (also known as 1999 RQ36) is one of more than 500,000 known asteroids, with estimates of undiscovered ones in the millions, in our Solar System as of 2010.

just the beginning of the space station becoming a part of the global Earth observing network," ISS chief scientist Julie Robinson said in the release. NASA has long wanted to send a mission to Mars to grab some of its surface and sling it back to Earth. But it looks like the agency will snag a sample from a measly asteroid before returning pieces of the Red Planet home. A US mission to return an asteroid sample is approved, funded and set to launch on an Atlas 5 rocket from Florida in September 2016 similar missions to Mars are stuck as attachments to interminable e mail threads. The asteroid return mission qualifies as sophisticated exploration, building on the US space agency's wildly successful two decade run of robotic missions to Jupiter, Saturn and the terrestrial planets. But Japan's space agency JAXA already won the race to take home an asteroid sample.
But Bennu is only one of five asteroids, Smith said, that met all these criteria: more than 200 meters across, carbonaceous and i.

The spacecraft is being built at Lockheed Martin in Denver, whereas the camera system is being designed and refined at Tucson, the academic home of ace planetary cameraman Peter Smith. Smith brightened the days of many a space reporter covering NASA planetary mission briefings during the 1990s and 2000s with his straight talk and white hair not cut to government specifications. "In 2019 OSIRIS will touch Bennu's surface like a pogo stick, and a burst of gas will cause loose rock to flow into a collector," Smith explained in August to an Alaska bound Scientific American Nike Air Jordan 6 Black
Hayabusa looked like a jinxed mission at several junctures with fuel, communications and engine troubles. But once it successfully dropped its collection canister in the Australian desert, a last ditch dental style scraping in 2010 yielded miniscule amounts of dust taken from the miniature asteroid Itokawa. JAXA might even beat the US to a second sample return as its Hayabusa 2 mission is in the works. The engineers behind NASA's mission to Asteroid Bennu aim for a smoother mission. Its name is a mouthful even as an acronym OSIRIS REx, which stands for Origins Spectral Interpretation Resource Identification and Security Regolith Explorer. The approval process for this US$800 million effort took so long that its initial primary investigator, Michael Drake, of the University of Arizona in Tucson, died at 65 before it came to fruition.
