NASA’s Lucy 12-Year Mission to Jupiter’s Trojan Asteroids Launches This Week – How To Watch It Live


On October 16, 2021,

Live launch coverage will begin at 5 a.m. EDT on NASA Television, the NASA app, and the agency’s website. NASA will hold a prelaunch briefing Wednesday, October 13, and science and engineering briefings October 14.

Over its 12-year primary mission, Lucy will explore a record-breaking number of asteroids. The spacecraft will fly by one asteroid in the solar system’s main belt and seven Trojan asteroids. Lucy’s path will circle back to Earth three times for gravity assists, which will make it the first spacecraft ever to return to our planet’s vicinity from the outer solar system.


Lucy will be the first space mission to explore the Trojan asteroids. These are a population of small bodies that are left over from the formation of the solar system. They lead or follow Jupiter in their orbit around the Sun, and may tell us about the origins of organic materials on Earth. Lucy will fly by and carry out remote sensing on six different Trojan asteroids and will study surface geology, surface color, and composition, asteroid interiors/bulk properties, and will look at the satellites and rings of the Trojans.

Lucy is the first mission to explore the Jupiter Trojans – two swarms of asteroids that share Jupiter’s orbit, leading and trailing the giant planet by sixty degrees. These primitive bodies are thought to be the “fossils” of planet formation, trapped by Jupiter’s gravity at the dawn of the solar system. Now, NASA is sending Lucy on a winding, twelve-year-long path to visit one main-belt asteroid and seven Jupiter Trojans. Lucy will provide the first up-close look at these mysterious objects, helping scientists to better understand the evolution of the solar system.

The launch of this mission is managed by NASA’s Launch Services Program, based at Kennedy, America’s premier multi-user spaceport. Goddard provides overall mission management, systems engineering, and safety and mission assurance. Lucy’s principal investigator is based out of the Boulder, Colorado, branch of Southwest Research Institute. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the agency’s Science Mission Directorate in Washington.

United Launch Alliance is the rocket provider for Lucy’s launch. Lockheed Martin Space in Littleton, Colorado, built the spacecraft.
