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.
This image shows the asteroid Dinkinesh and its satellite as seen by the Lucy Long-Range Reconnaissance Imager (L'LORRI) as NASA's Lucy spacecraft departed the system. This image was taken at 1 p.m. EDT (1700 UTC) Nov. 1, 2023, about 6 minutes after closest approach, from a range of approximately 1,010 miles (1,630 km). From this perspective, the satellite is revealed to be a contact binary, the first time a contact binary has been seen orbiting another asteroid.

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.
