OSIRIS-REx to search for Trojan Asteroids

In February, the spacecraft OSIRIS-REx will begin a search for Trojan asteroids—unique asteroids that share Earth’s orbit. The search will take place over a period of 10-12 days and will be conducted by a team at UA’s Lunar and Planetary Laboratory. “[This search] gives us a chance to really practice a maneuver that we will execute again in 2 years and ensure that we’re performing it correctly, our cameras are working appropriately, and it’ll be an added plus if, during that search, we find a Trojan asteroid,” said Sara Knutson, OSIRIS-REx science operations lead engineer for the mission.
