![]() The total cost for the launch was estimated to be US$148.3 million. ![]() On 31 January 2019, NASA announced that Lucy would launch in October 2021 on an Atlas V 401 launch vehicle from Cape Canaveral, Florida. On 4 January 2017, Lucy and Psyche were selected for development and launch. Its fellow finalists were DAVINCI, NEOCam, Psyche and VERITAS. On 30 September 2015, Lucy was selected as one of five finalist missions, each of which received US$3 million to produce more in-depth concept design studies and analyses. Twenty-eight proposals were received in all. Proposals had to be ready to launch by the end of 2021. Lucy was submitted as part of a call for proposals for the next mission(s) for Discovery Program that closed in February 2015. NASA selected Lucy through the Discovery Program Announcement of Opportunity (AO) released on 5 November 2014. Main article: Selection of Discovery Mission 13 and 14 There may be as many Trojans as there are asteroids in the asteroid belt. The Jupiter Trojans are at a similar distance but can be somewhat farther or closer to the Sun depending on where they are in their orbits. ![]() Jupiter is 5.2 AU (780 × 10 ^ 6 km 480 × 10 ^ 6 mi) from the Sun, or about five times the Earth-Sun distance. Jupiter Trojans have been observed by ground-based telescopes and the Wide-field Infrared Survey Explorer to be "dark with. NASA's Goddard Space Flight Center will manage the project.Įxploration of Jupiter Trojans is one of the high-priority goals outlined in the Planetary Science Decadal Survey. Levison of the Southwest Research Institute in Boulder, Colorado is the principal investigator, with Cathy Olkin of Southwest Research Institute as the mission's deputy principal investigator. Three instruments comprise the payload: a high-resolution visible imager, an optical and near-infrared imaging spectrometer, and a thermal infrared spectrometer. The mission may end with the Patroclus–Menoetius flyby, but at that point Lucy will be in a stable, 6-year orbit between the L4 and L5 clouds, and a mission extension will be possible. After these flybys, Lucy will return to Earth in 2031 for another gravity assist toward the L 5 Trojan cloud (the Trojan camp which trails about 60° behind Jupiter), where it will visit the binary Trojan 617 Patroclus with its satellite Menoetius in 2033. In 2027, it will arrive at the L 4 Trojan cloud (the Greek camp of asteroids that orbits about 60° ahead of Jupiter), where it will fly by four Trojans, 3548 Eurybates (with its satellite), 15094 Polymele, 11351 Leucus, and 21900 Orus. In 2025, it will fly by the inner main-belt asteroid 52246 Donaldjohanson, which was named after the discoverer of the Lucy hominin fossil. It gained one gravity assist from Earth on the 16th of October, 2022, and after making a flyby of the asteroid 152830 Dinkinesh in 2023, it will gain another in 2024. Lucy was launched from Cape Canaveral SLC-41 on 16 October 2021, at 09:34 UTC on the 401 variant of a United Launch Alliance Atlas V launch vehicle. Levison, Principal Investigator of the mission
