The payload fairing containing NASA’s Lucy spacecraft is hoisted up at the Vertical Integration Facility at Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on Oct. 7, 2021. It will be lowered onto the United Launch Alliance (ULA) Atlas V Centaur second stage. Lucy is scheduled to launch no earlier than Saturday, Oct. 16, on the ULA Atlas V 401 rocket from Launch Pad 41. NASA’s Launch Services Program, based at Kennedy Space Center, America’s premier multi-user spaceport, is managing the launch. Over 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 ever to return to the vicinity of Earth from the outer solar system.

Scheduled to launch early Saturday morning, Lucy will be the first spacecraft to study Jupiter's Trojan Asteroids. Like the mission's namesake – the fossilized human ancestor, "Lucy," whose skeleton provided unique insight into humanity's evolution – Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system.

Over 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 ever to return to the vicinity of Earth from the outer solar system.

NASA’s Lucy spacecraft is moved to the horizontal position on a rotation stand inside the Astrotech Space Operations Facility in Titusville, Florida, on Sept. 1, 2021. In view, the high gain antenna and solar arrays have been installed on the Lucy spacecraft.

A United Launch Alliance V 401 rocket, with NASA’s Lucy spacecraft atop, powers off the pad at Cape Canaveral Space Force Station’s Space Launch Complex 41 in Florida at 5:34 a.m. EDT on Saturday, Oct. 16, 2021. The launch was managed by NASA’s Launch Services Program, based at Kennedy Space Center. Lucy will embark on a 12-year primary mission to explore a record-breaking number of asteroids, including the Jupiter Trojan asteroids. Named after a fossilized human ancestor whose skeleton provided discoverers insight into humanity’s evolution, the Lucy mission will do much of the same, providing scientists and researchers a look into the origins of our solar system.

Shown is a view of the Vehicle Assembly at NASA’s Kennedy Space Center in Florida, on Oct. 16, 2021 – in the early-morning hours on the day of the Lucy mission. A United Launch Alliance V 401 rocket roared off the pad at Cape Canaveral Space Force Station’s Space Launch Complex 41 on at 5:34 a.m. EDT, carrying NASA’s Lucy spacecraft into space. 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. Lucy is the first space mission to study the Trojan asteroids, which hold vital clues to the formation of our solar system.
