Instrument built by Maxar Technologies' MDA for NASA's OSIRIS-REx Mission provides high resolution 3D scans of the Asteroid Bennu

Brampton, ON- MDA, a Maxar Technologies company (NYSE: MAXR) (TSX: MAXR), today announced that the laser altimeter instrument it built for the Canadian Space Agency’s (CSA) contribution to NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission has scanned and collected its first data set of Bennu, an asteroid in our solar system.

Launched on September 8, 2016, OSIRIS-REx will study and ultimately return a physical sample of Bennu to Earth. The CSA contributed the MDA-built OSIRIS-REx Laser Altimeter (OLA) instrument, a scanning Light Detection and Ranging (LIDAR) sensor. Powerful enough to scan Bennu from up to seven kilometers away, OLA will measure the distance between the spacecraft and Bennu by firing short pulses of laser light toward the asteroid and measuring the time of return flight for each pulse to produce an accurate and precise 3D model of Bennu’s shape and other exterior structures. This data will be valuable to scientists to better understand the characteristics of Bennu and will help OSIRIS-REx mission planners select the optimal location to gather a sample of the asteroid for return and analysis on Earth.

“This mission is another excellent example of an innovative Canadian technology that supports global space exploration and expands the scientific knowledge and discoveries for humankind,” said Mike Greenley, group president of MDA. “MDA has an industry-leading space portfolio with expertise in space robotics, sensors and exploration capabilities, further enhanced by our recent acquisition of Neptec, whose powerful and versatile sensor and vision systems augment the functionality of robotic systems and deliver guidance and navigation information for space vehicles.”

Maxar Technologies’ MDA has provided similar science instruments on successful spaceflight missions such as the U.S. Air Force XSS-11 and NASA Phoenix Mars Lander missions.

The OSIRIS-REx spacecraft arrived at Bennu on December 3, 2018, with OLA beginning its scans shortly thereafter. After the sample site is selected, a sample is set to be collected in July 2020. The OSIRIS-REx spacecraft will begin its return journey in March 2021, and deliver the sample back to Earth in September of 2023.
