Surprise! NASA’s Lucy spacecraft gets a new asteroid target!
NASA's Lucy spacecraft has got a new asteroid target. According to the information provided by the space research organisation, Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On November 1, 2023, the spacecraft will get a close-up view of a small main-belt asteroid to conduct an engineering test of the spacecraft's innovative asteroid-tracking navigation system.
The Lucy mission is already breaking records by planning to visit nine asteroids during its 12-year tour of the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not scheduled to get a close-up view of any asteroids until 2025, when it will fly by the main belt asteroid (52246) Donaldjohanson. However, the Lucy team identified a small, as-yet unnamed asteroid in the inner main belt, designated (152830) 1999 VD57, as a potential new and useful target for the Lucy spacecraft.
“There are millions of asteroids in the main asteroid belt,” said Raphael Marschall, Lucy collaborator of the Nice Observatory in France, who identified asteroid 1999 VD57 as an object of special interest for Lucy. “I selected 500,000 asteroids with well-defined orbits to see if Lucy might be traveling close enough to get a good look at any of them, even from a distance. This asteroid really stood out. Lucy's trajectory as originally designed will take it within 40,000 miles of the asteroid, at least three times closer than the next closest asteroid,” Marschall added.
The Lucy team realized that, by adding a small maneuver, the spacecraft would be able to get an even closer look at this asteroid. So, on January 24, the team officially added it to Lucy's tour as an engineering test of the spacecraft's
