Just Passing By: the Globe of Earth Imaged by OSIRIS-REx

Here’s our beautiful blue marble as seen by NASA’s OSIRIS-REx spacecraft on Sept. 22, 2017 from a distance of 106,000 miles (170,000 km). It had just completed a gravity-assist flyby of Earth—a little 19,000 mph “once around the block” that gave the spacecraft an 8,500-mile-an-hour speed boost necessary to adjust its course toward Bennu, the asteroid target of its mission.

NASA’s OSIRIS-REx Will Search for Asteroids Caught In Earth’s Orbit

In mid-February OSIRIS-REx will pass by the Earth-Sun L4 region, giving it an opportunity to search for asteroids. (University of Arizona)

Launched on Sept. 8, 2016, NASA’s OSIRIS-REx spacecraft is heading out into the main asteroid belt beyond the orbit of Mars to meet up with the 1,600-foot-wide asteroid Bennu. Ultimately OSIRIS-REx will map and collect a sample of Bennu’s surface, returning it to Earth in 2023. But while it’s still traveling through near-Earth space in preparation for a gravity-assist flyby this September, mission scientists will take advantage of OSIRIS-REx’s position near L4 to look for any captured “Trojan” asteroids.

NASA is about to embark on its first mission to sample an asteroid—and I’ll have a front-row seat to the launch!

On Thursday, Sept. 8, at 7:05 p.m. (23:05 UTC) the launch window opens for the launch of OSIRIS-REx, NASA’s mission to visit the near-Earth asteroid Bennu, orbit and map it, collect a sample and return it to Earth. The 8-foot-wide, 20-foot-long spacecraft will launch aboard a ULA Atlas V rocket from Cape Canaveral AFS and as a member of the latest NASA Social event I and 99 other attendees will be at the Cape to see it off on its 7-year journey. Be sure to follow me on Twitter and Instagram to see pictures and videos from the two-day event on Sept. 7–8, and follow the #NASASocial hashtag on Twitter too!
