NASA’s Lucy spacecraft is less than one month away from its next asteroid encounter. As it approaches, Lucy is keeping an eye on its target, the small main belt asteroid Donaldjohanson, using its high-resolution imager, L’LORRI, for optical navigation. At its closest point, Lucy will fly 600 miles (960 km) from Donaldjohanson, a distance carefully...
UPDATE AS OF DEC. 13, 2024 Shortly after 11:30 p.m. EST, Thursday Dec. 12, NASA’s Lucy spacecraft resumed communications with Earth following the short, planned communication blackout that occurred in the hours around closest approach during its second Earth gravity assist. NASA’s CARA (Conjunction Assessment Risk Analysis) operators determined that no spacecraft maneuvers were necessary …
UPDATE AS OF FEB. 5, 2024: On Feb. 3, NASA's Lucy spacecraft completed the largest planned main engine burn of its 12-year mission. During this deep space maneuver, the main engines operated for over 36 minutes. UPDATE AS OF FEB. 1, 2024: On Jan. 31, NASA's Lucy spacecraft completed the first main engine burn of …
The satellite discovered during the first asteroid encounter of NASA's Lucy mission has an official name. On Nov. 27, 2023, the International Astronomical Union approved the name "Selam" or ሰላም, which means "peace" in the Ethiopian language Amharic, for Dinkinesh's moon. "Dinkinesh is the Ethiopian name for the fossil nicknamed ‘Lucy,'", says Raphael Marshall of …
The Lucy operations team has confirmed that NASA's Lucy spacecraft has phoned home after its encounter with the small main belt asteroid, Dinkinesh. Based on the information received, the team has determined that the spacecraft is in good health and the team has commanded the spacecraft to start downlinking the data collected during the encounter. …
We are only a few hours away from the NASA Lucy spacecraft's first close up look at the small inner-main belt asteroid, Dinkinesh. Dinkinesh is 10 to 100 times smaller than the Jupiter Trojan asteroids that are the mission's main targets. The Dinkinesh encounter serves as a first in-flight test of the spacecraft's terminal tracking …
NASA's Lucy spacecraft is on track for its first asteroid encounter on Nov. 1. Lucy's optical navigation team has confirmed that the latest trajectory correction maneuver on Sept 29 accurately set the spacecraft on course for its flyby of the small main belt asteroid Dinkinesh. The spacecraft is anticipated to pass approximately 265 miles (425 …
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 travelling at approximately 43,000 mph …
NASA's Lucy mission team has decided to suspend further solar array deployment activities. The team determined that operating the mission with the solar array in the current unlatched state carries an acceptable level of risk and further deployment activities are unlikely to be beneficial at this time. The spacecraft continues to make progress along its …
UPDATE AS OF DECEMBER 15, 2022: The Lucy team updated the spacecraft's attitude controller on Dec. 6, resolving the previously observed vibration interaction between the controller and the solar array structural modes. As previously reported, the vibration was too small to pose a risk and the spacecraft continues to operate safely. The team resumed solar …
