NASA’s Lucy mission took beautiful closeup pictures of the moon after utilizing Earth to achieve a gravity-assisted increase for its journey to go to Jupiter’s Trojan asteroids.
Lucy carried out the primary of three deliberate Earth flybys on Oct. 16, getting as shut as 220 miles (360 kilometers) to our planet, making Lucy visible to some viewers on the bottom. Hours after its planetary cross, the spacecraft skilled its L’LORRI (Lucy Lengthy Vary Reconnaissance Imager) digital camera on our nearest neighbor to seize some spectacular photographs of the moon in a process meant to arrange for the mission’s asteroid flybys.
The primary picture, taken about 6.5 hours after the closest method to Earth, is a mix of 10 separate 2-millisecond exposures exhibiting the lunar central highlands, with every pixel representing roughly 0.8 miles (1.3 km), in line with a statement.

A mosaic picture, consisting of 5 separate 1-millisecond exposures, was created utilizing pictures taken between 7.5 and eight hours after the flyby of Earth. The tall picture exhibits the moon’s rugged, closely cratered, southern highlands close to the underside of the mosaic, the traditional, lava-filled impression basin Mare Imbrium (“Sea of Rains”) close to the highest, and the terminator, or day-night line, to the left.
Lucy additionally picked up a single shot of the moon capturing round 600 miles (1000 km) of lunar terrain, primarily exhibiting the huge basin of Mare Imbrium and the Apennine Mountains within the lower-right portion of the picture.
The photographs had been taken when Lucy was between 140,000 miles (230,000 km) and 160,000 miles (260,000 km) away from the moon. For comparability, the average distance between Earth and the moon is about 238,900 miles (382,400 km).
In addition to delivering spectacular photos, the train is useful for Lucy’s most important asteroid-surveying mission as a result of it helps scientists perceive Lucy’s devices’ means to detect craters, which planetary scientists use to know the age of surfaces throughout the solar system.Â
Lucy would be the first spacecraft to journey to Jupiter‘s Trojan asteroids, which orbit the sun in two clumps, one forward of and one behind the large planet at gravitational secure “parking spots” referred to as Lagrange points.Â
Lucy will use a second Earth flyby in 2024 to achieve sufficient velocity to go to Trojan asteroids at Lagrange level 4 forward of Jupiter, earlier than utilizing a last Earth flyby in 2030 to trek to scope out Trojans trailing Jupiter, at Lagrange level 5.Â
