NASA's Lucy spacecraft adjusts course for asteroid flyby in November

On May 9, NASA's Lucy spacecraft carried out a trajectory correction maneuver to set the spacecraft on course for its close encounter with the small main belt asteroid Dinkinesh. The maneuver changed the velocity of the spacecraft by only about 7.7 mph (3.4 m/s).

Even though the spacecraft is currently traveling at approximately 43,000 mph (19.4 km/s), this small nudge is enough to move the spacecraft nearly 40,000 miles (65,000 km) closer to the asteroid during the planned encounter on Nov. 1, 2023. The spacecraft will fly a mere 265 miles (425 km) from the small, half-mile-(sub-km)-sized asteroid, while traveling at a relative speed of 10,000 mph (4.5 km/s).

The Lucy team will continue to monitor the spacecraft's trajectory and will have further opportunities to fine tune the flight path if needed.

The Lucy team is also continuing to analyze the data collected from its spring instrument calibration campaign and make other preparations for the mission's first asteroid encounter. This encounter will provide a valuable test of the spacecraft's systems and procedures to make sure that everything operates as expected during the mission's high-speed asteroid encounters.
