"Lucy's Milestone: NASA's Asteroid Probe Fires Main Engines in Space en Route to Jupiter Trojans"

NASA's Lucy spacecraft will fire its main engines in space for the first time since its launch in August 2021, burning through around half of its onboard fuel. This maneuver aims to change Lucy's velocity by around 2,000 miles per hour. The spacecraft will then undergo a flyby of Earth in December 2024 to receive a gravity assist, altering its trajectory to explore the Trojan asteroids near Jupiter.
