Scheduled for launch in September 2016, OSIRIS-REx will visit the asteroid Bennu to survey, land, and return a sample of its surface material. During the approach, OLA will scan Bennu’s surface and create a high-resolution 3D map of the entire asteroid, which will help scientists understand its morphology and select the best spot for OSIRIS-REx to collect its sample. Because Bennu is a carbonaceous asteroid that has likely changed very little since the birth of the solar system, scientists hope that this mission will shed light on how the solar system developed.
OLA, one of the most advanced lidar instruments ever used for such a mission, is equipped with a rapid scanning mirror and two separate lasers. While many earlier space missions have used simple laser rangefinders to measure the distance to their targets, OLA will use its scanning technology to spread its measurements over the entire asteroid, creating a 3D map of Bennu. The two lasers give OLA extra flexibility for long- and short-range operation: The long-range laser makes measurements from up to 7 km away as OSIRIS-REx approaches Bennu, while the short-range laser fires up to 10,000 times per second to create detailed maps quickly once OSIRIS-REx is in close orbit.
“It has been five years since the beginning phase of this project, and I’m very proud of the team that delivered this complex instrument on schedule,” said Dr. Paul LaRocque, Teledyne Optech’s Vice President for Special Projects. “NASA and the CSA were pleased with our performance, which comes from Teledyne Optech’s long experience in creating lidar systems for space operations.”
OLA is not the first Teledyne Optech lidar to travel into space. Teledyne Optech designed the atmospheric lidar aboard NASA’s Phoenix Mars Lander, which returned a trove of information about the weather, including proof that it actually snows on the red planet. In an application similar to OSIRIS-REx, Teledyne Optech also created the rendezvous lidar for US Air Force Research Lab satellite XSS-11, which successfully tracked other satellites in orbit to assess the possibility of satellite docking and servicing.
