NASA’s Lucy spacecraft is about to have its second shut encounter with an asteroid

A NASA spacecraft will make an in depth method to an asteroid in the principle belt on Sunday afternoon, within the second of a number of asteroid flybys deliberate for its 12-year mission to check remnants of the early photo voltaic system. The Lucy spacecraft will probably be 596 miles (960 km) from asteroid Donaldjohanson — named after the paleoanthropologist who found the “Lucy” hominin fossil — on the closest level of its go, which can happen at 1:51PM ET, in keeping with NASA. Lucy will use three devices to seize detailed observations as the thing will get nearer, rotating with the asteroid over a couple of hours to get the total image. It can cease monitoring simply earlier than the asteroid is nearest, when it’ll must protect its devices because of the place of the solar to forestall damaging them.

The spacecraft beforehand visited a small asteroid known as Dinkinesh in 2023, and its observations revealed that the asteroid is orbited by what’s known as a contact binary, or a peanut-shaped double moon “product of two smaller objects touching one another,” NASA defined on the time. After Donaldjohanson, Lucy will transfer on to its important targets, a handful of “Trojan” asteroids orbiting the solar in the identical path as Jupiter. It’s anticipated to succeed in the primary of these objects in 2027.

“Each asteroid has a special story to inform, and these tales weave collectively to color the historical past of our photo voltaic system,” Tom Statler, Lucy mission program scientist, mentioned in a press launch. “The truth that every new asteroid we go to knocks our socks off means we’re solely starting to know the depth and richness of that historical past. Telescopic observations are hinting that Donaldjohanson goes to have an fascinating story, and I’m totally anticipating to be stunned — once more.”
