Lucy är en amerikansk rymdsond i NASA:s Discoveryprogram, utvecklad av Lockheed Martin, som ska studera flera av Jupiters trojaner. Rymdsonden sköts upp med en Atlas V-raket den 16 oktober 2021.
Rymdsondens uppgift är att studera en rad olika asteroider, genom att flyga förbi dem på relativ nära håll. Under resan kommer den även att passera jorden tre gånger.
Instrument
- L'Ralph - Kamera för ljus 0,4-0,85 μm och för infrarött ljus 1,0-3,6 μm.[2]
- L'LORRI - Kamera med hög upplösning för synligt ljus 0,35-0,85μm.[2]
- L'TES - infrarött ljus 6-75 μm.[2]
- Gravity/Radio Science - rymdsondens radioutrustning kan även användas för att göra ett antal olika vetenskapliga undersökningar.

NASA’s Lucy spacecraft, with its high gain antenna attached, is on a rotation stand inside the Astrotech Space Operations Facility in Titusville, Florida on Sept. 8, 2021. Lucy is scheduled to launch no earlier than Saturday, Oct. 16, on a United Launch Alliance Atlas V 401 rocket from Launch Pad 41 at Cape Canaveral Space Force Station. NASA’s Launch Services Program based at Kennedy Space Center 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.

A United Launch Alliance Atlas V rocket with the Lucy spacecraft aboard launches from Space Launch Complex 41, Saturday, Oct. 16, 2021, at Cape Canaveral Space Force Station in Florida. 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.

This image shows the “moonrise” of the satellite as it emerges from behind asteroid Dinkinesh as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI), one of the most detailed images returned by NASA’s Lucy spacecraft during its flyby of the asteroid binary. This image was taken at 12:55 p.m. EDT (1655 UTC) Nov. 1, 2023, within a minute of closest approach, from a range of approximately 270 miles (430 km). From this perspective, the satellite is behind the primary asteroid. The image has been sharpened and processed to enhance contrast.
