An unmanned NASA spacecraft named Lucy is making the first space mission to the Jupiter Trojan asteroids, small bodies that share an orbit with the fifth planet from the sun. Lucy’s payload includes a plaque imprinted with words of wisdom for future explorers to find – including poetry from University of Virginia professor Rita Dove.
The spacecraft – more than 52 feet tip to tip, with its two circular solar arrays unfurled, each close to 24 feet in diameter – is scheduled to launch between Saturday and Nov. 7. It will embark on a 12-year journey to study some of the asteroids in “the swarms of Trojan asteroids associated with [but not actually near] Jupiter,” according to NASA’s . “These primitive bodies hold vital clues to deciphering the history of the solar system.”
After 2033, when the mission of sending back a variety of data and images concludes, the Lucy spacecraft will continue on a stable orbit, travelling between the Earth and the Trojan asteroids – for hundreds of thousands, if not millions, of years.
The mission takes its name from the fossilized human ancestor, nicknamed “Lucy,” whose bones, discovered in Ethiopia in 1974, provided unique insight into humanity’s evolution, the website says. (Those paleontologists, in turn, named the skeleton after the Beatles’ song, “Lucy in the Sky with Diamonds.”)
