On January 9, 2020, the Lucy mission officially announced that it would be visiting not seven, but eight asteroids. As it turns out, Eurybates, one of the asteroids along Lucy’s path, has a small satellite. Learn about its discovery in this video.

Lucy Mission to the Trojan Asteroids
NASA’s Lucy mission is the first spacecraft launched to the Trojan asteroids, a population of primitive asteroids orbiting in tandem with Jupiter. These are remnants of planetesimals – the primitive building blocks that formed the planets – that were captured in two regions, near points where the gravitational influence of Jupiter and the Sun balance. These primitive bodies hold vital clues to deciphering the history of the solar system, and perhaps even the origins of organic material on Earth.
Launched on Oct. 16, 2021, Lucy is the first space mission to study the Trojans. 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. Lucy will complete a 12-year journey to eight different asteroids – a main belt asteroid and seven Trojans, four of which are members of “two-for-the-price-of-one” binary systems.

NASA’s Lucy mission launched at 5:34 a.m. EDT on Oct. 16, 2021, on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.
First conceived seven years ago as a mission to two asteroids, Lucy expanded to epic proportions thanks to creative engineering and impeccable timing. Some imagine karma may have had something to do with it as well. Learn how the mission came to be.
Lucy, NASA’s first spacecraft to explore the Trojan asteroids, arrived July 30, 2021, at the agency’s Kennedy Space Center in Florida.
After the Lucy spacecraft completes its mission, it will continue to travel in space for at least hundreds of thousands of years. It is easy to imagine that in the distant future our descendants will find Lucy floating among the planets. Therefore, the Lucy team chose to put a time capsule aboard the Lucy spacecraft in the form of a special plaque.
Learn how the Lucy mission’s targets were discovered and named.
Before the NASA Lucy mission began its long journey to the Trojan asteroids, the Lucy LOng Range Reconnaissance Imager (L’LORRI) was successfully integrated into the spacecraft on Oct. 30, 2020.
NASA’s Lucy mission’s second scientific instrument, the Lucy Thermal Emission Spectrometer (L’TES), was successfully integrated into the spacecraft on Dec. 16, 2020.
NASA’s Lucy mission’s third and final scientific instrument, L’Ralph, was built by NASA’s Goddard Space Center and was integrated into the spacecraft on Jan. 26, 2021. L’Ralph is the most complicated instrument on Lucy, as it is actually two instruments in one.
