DTN News - NASA NEWS: Why NASA Chose Potentially Threatening Asteroid For New Mission....NSI News Source Info # 2024

(NSI News Source Info) TORONTO, Canada - May 31, 2011:

When it comes to visiting asteroids, NASA doesn't pick run-of-the-mill space rocks. The target of NASA's latest asteroid mission is not only thought to be rich in the building blocks of life, it also has a chance — although a remote one — of threatening Earth in the year 2182.

The asteroid 1999 RQ36 is the target of a new unmanned spacecraft, which NASA plans to launch in 2016 to collect a sample from the space rock and return it to Earth by 2023.

The mission's leaders spent a long time surveying possible destinations for the mission, and finally settled on 1999 RQ36. NASA calls the mission OSIRIS-Rex, which is short for Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer.

"We went through a whole series of selection criteria," OSIRIS-Rex's deputy principal investigator Dante Lauretta, a planetary scientist at the University of Arizona, told SPACE.com. "There are over 500,000 asteroids known. [1999 RQ36] looks really optimum." [Video: The OSIRIS-Rex Mission to 1999 RQ36]
