NASA has successfully launched the OSIRIS-REx space probe on Thursday, which aims to take a sample of asteroid Bennu and return to Earth. CNN reports: "The probe is scheduled to arrive at Bennu in August 2018. For months it will hang out -- take pictures, make scans of the asteroid's surface and create a map. Then in July 2020, OSIRIS-REx wil unfurl its 11-foot-long (3.35-meter) robot arm called TAGSAM and make contact with Bennu's surface for about five seconds. During those seconds, the arm will use a blast of nitrogen gas to kick up rocks and dust and then try to snag a sample of the dust and store it. NASA hopes to get at least 2 ounces (60 grams) and maybe as much as 4.4 pounds (2 kilograms) of asteroid dust and small rocks. OSIRIS-REx heads home in March 2021 and arrives back at Earth on September 24, 2023, but it won't land. In a bit of Hollywood-style drama, it will fly over Utah and drop off the capsule holding the asteroid sample. A parachute will guide the capsule to the ground at the Utah Test and Training Range in Tooele County." OSIRIS-REx is an acronym for the objectives of the mission: Origins, Spectral Interpretation, Resource Identification and Security-Regolith Explorer. It spells the name of the Egyptian god Osiris. The report adds that while the mission is a first for NASA, it is not a first for mankind. "Japan's Hayabusa spacecraft brought back a small sample of asteroid Itokawa dust in 2010."
