This is Earth and the Moon from 40 Million Miles Away

That’s here; that’s home; that’s us—the two bright objects in this picture are Earth and the Moon, imaged by NASA’s OSIRIS-REx spacecraft on January 17, 2018 from a distance of 39.5 million miles (63.5 million km). This is about the distance between Earth and Mars at their closest points to each other (give or take…

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…

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

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…

NASA Readies OSIRIS-REx to Visit an Asteroid

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…
