In the historic quest to bring samples from across the solar system back to Earth, the best mantra for success may be a simple, familiar phrase: “practice makes perfect.”
At least, that’s the feeling from recent dry runs of the grand finale of NASA’s OSIRIS-REx, an acronym for the megamouthful Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer. Launched in September 2016, OSIRIS-REx is the first U.S.
NASA spacecraft takes next steps to drop off asteroid bits in Utah
NASA's OSIRIS-REx spacecraft got approved for a second mission to study asteroid Apophis when it makes a close flyby of Earth in 2029.
After a 7-year journey to collect a sample from the asteroid Bennu, the spacecraft made a course correction burn on Wednesday to set it on track to drop off a special package to Earth.

On Sept. 24, seven years after it blasted off from its Florida launch pad, NASA's OSIRIS-REx spacecraft is expected to drop a capsule into the Earth's atmosphere containing matter plucked from the surface of an asteroid dating from the early history of the solar system.
"I've never worked with extraterrestrial material," said Dominique Weis, a geoscientist at the University of British Columbia, who's in line to get a tiny sample.
