Highlights
Second Earth Gravity Assist
On Dec. 12, 2024, at 11:15 p.m. EST, NASA's Lucy spacecraft, currently in a two-year orbit around the Sun, skimmed Earth's atmosphere, passing only about 220 miles (360 kilometers) above the surface. This close flyby resulted in a "gravity assist," putting the spacecraft on a new trajectory that travels through the main asteroid belt and out to the never-before-explored Jupiter Trojan asteroids, small bodies that orbit the Sun at the same distance as Jupiter.

Dinkinesh: Lucy's First Asteroid Flyby
NASA's Lucy spacecraft flew by not just its first asteroid, but its first three, on Nov. 1, 2023. Early images returned by Lucy reveal that the small main belt asteroid Dinkinesh has a contact binary as a satellite (that is, its satellite is made of two smaller objects touching each other). The Lucy team used this encounter as an opportunity to test out spacecraft systems and procedures.

First Earth Gravity Assist
After a year in orbit around the Sun, the Lucy spacecraft returned home on its launch anniversary for the first of three Earth gravity assists. On Oct. 16, 2022, Lucy flew by the Earth like a partner in a swing dance, boosting its speed and elongating its orbit around the Sun. Lucy made its closest approach at just 224 miles (360 km) above Earth: lower than the International Space Station. This close encounter helped Lucy gain more speed so that it can reach its targeted Trojan asteroids.

Lucy's Journey Begins
Launched on Oct. 16, 2021, Lucy is the first space mission to study the Trojan asteroids. The mission takes its name from the fossilized human ancestor (called "Lucy" by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of the solar system.
