On October 16, NASA launched the first-ever mission to explore Jupiter's Trojan asteroids – Lucy. At 5:34 AM EDT, the mission was launched from the Space Launch Complex 41 at Cape Canaveral Space Force Station atop the Atlas V rocker. The mission will last until 2033, and for the first time in history, will explore several of Jupiter's Trojan asteroids in close proximity.

Lucy will study a group of asteroids orbiting the largest planet of our solar system, Jupiter. The mission could help scientists shed light on how the solar system was formed. They believe that Trojan asteroids may be remnants of planetesimals, the building blocks of our solar system.

According to scientists, Jupiter could have attracted planetesimals during the migration of giant planets to the outskirts of the system 3.9 billion years ago. These are "time capsules" that can tell us what happened more than four billion years ago and help us better understand how the solar system was formed (and we as part of it).

In the next twelve years, Lucy will fly near one main-belt asteroid and seven Trojan asteroids, which will mark the agency's first mission to study so many asteroids at once.

The mission is named after the fossilized skeleton of Lucy, one of the earliest known human ancestors.
