NASA on Saturday launched a probe toward clusters of asteroids along Jupiter's orbital path. They're known as the Trojan swarms, and they represent the final unexplored regions of asteroids in the solar system. The spacecraft, a deep-space robotic archaeologist named Lucy, will seek to answer pressing questions about the origins of the solar system, how the planets migrated to their current orbits and how life might have emerged on Earth.
"We have never gone this far to study asteroids," said NASA administrator Bill Nelson. "In so doing, we're going to be able to better understand the formation of the solar system, and better understand ourselves and our development."
After a six-year cruise, Lucy will fly close to seven Trojan asteroids through 2033, completing wild circuits of the Sun that conjure the outline of a Formula 1 racetrack in some graphic renderings.
