NASA’s Lucy Reveals Wobbling, Peanut-Shaped AsteroidEven small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the […]
NASA’s Lucy Spacecraft Prepares Second Asteroid EncounterIMAGE

NASA’s Lucy Spacecraft Prepares Second Asteroid EncounterNASA’s Lucy spacecraft is 6 days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson. This upcoming event represents a comprehensive “dress rehearsal” for Lucy’s main mission over the next decade: the exploration of multiple Trojan asteroids that […]

NASA Selects Participating Scientists to Join Lucy Asteroid MissionNASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early solar system trapped on stable orbits associated with — but not close to — the planet Jupiter. NASA’s Lucy in the L4 Trojans Participating Scientist Program supports scientists to carry out new investigations […]

NASA’s Lucy Spacecraft Takes Its 1st Images of Asteroid DonaldjohansonNASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid. Lucy will pass within 596 miles […]

Lucy completes its first Earth gravity assist after a year in spaceA year after its launch, NASA’s Jupiter Trojan asteroid explorer Lucy has completed its first of multiple Earth gravity assists on its journey to explore nine asteroids. Lucy is a first-of-its-kind mission to visit several Trojan asteroids in Jupiter’s L4 and L5 Lagrange points. The mission’s closest approach to Earth occurred on Oct. 16 at 7:04 AM EDT (11:04 UTC).

Lucy asteroid probe to set a new distance record for solar-powered spacecraftAbout an hour after launch Saturday, NASA’s Lucy spacecraft will start the delicate process of opening its circular, fan-shaped solar arrays — the largest ever on a deep space probe — to power the asteroid explorer’s 12-year journey into the outer solar system. When it reaches the apex of its interplanetary orbital arc, the Lucy mission will become the most distant spacecraft to ever use solar power, breaking the record set by NASA’s Juno spacecraft orbiting Jupiter. Lucy will fly by eight asteroids during its mission, including seven objects in the Trojan swarms that lead and trail Jupiter in its orbit around the sun. The mission is the first to explore the Trojan asteroids, which scientists say are leftover building blocks similar to objects that came together to form the solar systems giant outer planets. To get there, Lucy will rely on a few engineering innovations. “The most obvious feature that we have on Lucy is our gigantic, amazing solar array wings,” said Katie Oakman, struct

NASA’s Lucy asteroid mission 10 days from launchFueled up for a 12-year mission of exploration, NASA’s Lucy science probe is nearly ready for launch Oct. 16 from Florida’s Space Coast to begin a journey through the solar system to visit eight asteroids, a record number for a single mission. Ground teams completed testing of the Lucy spacecraft last month inside a climate-controlled clean room at the Astrotech payload processing facility in Titusville, Florida, a few miles from the gates to NASA’s Kennedy Space Center. The tests capped a two-month campaign at Astrotech since the Lucy spacecraft arrived from its Lockheed Martin factory in Colorado. Technicians loaded hydrazine and nitrogen tetroxide propellants into the probe to feed its small maneuvering thrusters and main engine, which will help steer Lucy toward its asteroid targets. “Lucy is done, and we’re ready to fly,” said Hal Levison, the mission’s principal investigator from the Southwest Research Institute, or SWRI, in Boulder, Colorado. The $981 million mission will be the
