Lucy L-2 Science and Instrument Briefing

NASA will hold a virtual media briefing at 1 p.m. EDT Thursday, October 14th, to preview the launch of the agency’s first spacecraft to study Jupiter’s Trojan asteroids. The Trojan asteroids are remnants of the early solar system clustered in two “swarms” leading and following Jupiter in its path around the Sun.

The live briefing will stream on NASA Television, the agency's website, NASA’s Twitter account and the NASA App.

Participants in Thursday's briefing will include:
• Alana Johnson, Senior Communications Specialist, NASA Planetary Science Division
• Adriana Ocampo, Lucy Program Executive, NASA Headquarters
• Cathy Olkin, Lucy Deputy Principal Investigator, Southwest Research Institute
• Keith Noll, Lucy Project Scientist, NASA's Goddard Space Flight Center
• Hal Weaver, L’LORRI Instrument PI, Johns Hopkins University Applied Physics Laboratory
• Phil Christensen, L’TES Instrument PI, Arizona State University
• Dennis Reuter, L’RALPH Instrument PI, NASA's Goddard Space Flight Center

Over its 12-year primary mission, Lucy will explore a record number of asteroids in separate orbits around the Sun. The spacecraft will fly by one asteroid in the solar system’s main belt, located between the orbits of Mars and Jupiter, followed by seven Trojans. In addition, Lucy’s path will circle back to Earth three times for gravity assists, making it the first spacecraft ever to travel out to the distance of Jupiter and return to the vicinity of Earth.

The Lucy mission is named after the fossilized skeleton of an early hominin (pre-human ancestor) discovered in Ethiopia in 1974 and named “Lucy” by the team of paleoanthropologists who discovered it. Just as the Lucy fossil provided unique insights into humanity’s evolution, the Lucy mission promises to revolutionize our knowledge of planetary origins and the formation of the solar system.

Lucy is scheduled to launch no earlier than Saturday, Oct. 16, on a United Launch Alliance Atlas V 401 rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida.

Southwest Research Institute is the home institution of the principal investigator. NASA Goddard Space provides overall mission management, systems engineering, plus safety and mission assurance. Lockheed Martin Space built the spacecraft. 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 Science Mission Directorate. The launch is managed by NASA’s Launch Services Program based at Kennedy Space Center in Florida.
