After a nearly two-year space chase, NASA’s OSIRIS-REx probe finally has its asteroid target in sight.
OSIRIS-REx, which launched in September 2016, has captured its first imagery of the 1,650-foot-wide (500 meters) space rock Bennu, NASA officials announced today (Aug. 24).
The spacecraft snapped the photos on Aug. 17 — the same day it officially began its final approach toward Bennu — from a distance of 1.4 million miles (2.2 million kilometers).
“I can’t explain enough how much it meant for the team,” OSIRIS-REx principal investigator Dante Lauretta, of the University of Arizona, told reporters today. “I know Bennu is only a point of light here, but many of us have been working for years and years and years to get this first image down, and it really represents the beginning of the great scientific expedition that is OSIRIS-REx.”

“It’s Bennu’s size and small mass that make the navigation challenges on this mission unprecedented, really,” said Michael Moreau, OSIRIS-REx flight dynamics system manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “On December 31, when we insert into orbit, then it will become the smallest planetary object to ever be orbited by a spacecraft.
