NASA Cassini spacecraft imaged the surface of Saturn moon Helene as the it flew by the moon on Jan. 31, 2011. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit 60 degrees ahead of and behind Jupiter as it circles the Sun.

NASA Cassini spacecraft snapped this image during the spacecraft closest flyby of Saturn moon Helene, on March 3, 2010. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit ahead of and behind Jupiter.

Observations from NASA WISE all-sky survey reveal new clues about Jovian Trojans, mysterious asteroids that orbit in front of and behind Jupiter in its path around the sun seen here in an artist’s concept.

A United Launch Alliance V 401 rocket, with NASA’s Lucy spacecraft atop, soars into the sky after lifting off the pad at Cape Canaveral Space Force Station’s Space Launch Complex 41 in Florida at 5:34 a.m. EDT on Saturday, Oct. 16, 2021. The launch was managed by NASA’s Launch Services Program, based at Kennedy Space Center. Lucy will embark on a 12-year primary mission to explore a record-breaking number of asteroids, including the Jupiter Trojan asteroids. Named after a fossilized human ancestor whose skeleton provided discoverers insight into humanity’s evolution, the Lucy mission will do much of the same, providing scientists and researchers a look into the origins of our solar system.

Workers inside the Astrotech Space Operations Facility in Titusville, Florida, work to open and extend one of the solar arrays on NASA’s Lucy spacecraft on Aug. 19, 2021. Both solar arrays will be opened to make sure they operate correctly. In view installed on top of the spacecraft is the high gain antenna. Lucy is scheduled to launch no earlier than Saturday, Oct. 16, on a United Launch Alliance Atlas V 401 rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station. NASA’s Launch Services Program based at Kennedy Space Center is managing the launch. Over its 12-year primary mission, Lucy will explore a record-breaking number of asteroids, flying by one asteroid in the solar system’s main belt and seven Trojan asteroids. Additionally, Lucy’s path will circle back to Earth three times for gravity assists, making it the first spacecraft ever to return to the vicinity of Earth from the outer solar system.
