Thomas Zurbuchen, associate administrator, NASA’s Science Mission Directorate, is introduced during a prelaunch news conference for the Lucy mission held inside the TV Auditorium at NASA’s Kennedy Space Center in Florida on Oct. 13, 2021. The mission is scheduled to launch no earlier than 5:34 a.m. EDT Saturday, Oct. 16, on a United Launch Alliance Atlas V 401 rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station. NASA’s Launch Services Program, based at Kennedy, is managing the launch. During its 12-year primary mission, Lucy will explore a record-breaking number of asteroids, flying by one asteroid in the solar system’s main belt and seven Trojan asteroids. Additionally, Lucy’s path will circle back to Earth three times for gravity assists, making it the first spacecraft to return to the vicinity of Earth from the outer solar system.
