LOS ANGELES: The space capsule carrying a sample of rocky material plucked from an asteroid three years ago was moving to earth for a parachute landing in the Utah desert on Sunday, NASA said on Saturday.
Mission managers are expecting a “spot-on” touchdown on the U.S. military’s vast Utah Test and Training range, west of Salt Lake City, said Sandra Freund, program manager at Lockheed Martin, which designed and built the spacecraft.
The round, gumdrop-shaped capsule is scheduled to land by parachute at 10:55 a.m. EDT (1455 GMT), about 13 minutes after streaking into the top of the atmosphere at roughly 35 times the speed of sound, capping a seven-year voyage.
If successful, the OSIRIS-REx mission, a joint effort between NASA and scientists at the University of Arizona, would mark the third asteroid sample, and by far the largest, ever returned to Earth for analysis, following two similar missions by Japan’s space agency over the past 13 years.
OSIRIS-REx collected its specimen from Bennu, a carbon-rich asteroid discovered in 1999 and classified as a “near-Earth object” because it passes relatively close to our planet every six years. Scientists put the odds of it striking Earth at 1-in-2,700 in the late 22nd century.
