This image shows the asteroid Dinkinesh and its satellite as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI) as NASA’s Lucy Spacecraft departed the system. This image was taken at 1 p.m. EDT (1700 UTC) Nov. 1, 2023, about 6 minutes after closest approach, from a range of approximately 1,010 miles (1,630 km). From this perspective, the satellite is revealed to be a contact binary, the first time a contact binary has been seen orbiting another asteroid.


Lucy is the first spacecraft designed to fly to the Jupiter Trojans, with specific targets including DonaldJohanson (April 20, 2025), Eurybates with its satellite Queta (April 12, 2027), Polymele with its satellite (September 15, 2027), Leucus (April 18, 2028), Orus (November 11, 2028), and finally, Patroclus with its satellite Menoetius (March 3, 2033). Prior to these encounters, the spacecraft passed by the asteroid Dinkinesh and its satellite (November 1, 2023), which is not classified as a Jupiter Trojan. The exploration of this significant number of asteroids during Lucy's 12-year mission is unusually extensive and is expected to provide valuable insights into the formation of our solar system.

Auswahlprozess der ESA für M-Klasse Missionen.

M-Matisse shortlisted by ESA

The "M-Matisse" project, in which the Rhenish Institute for Environmental Research, Department of Planetary Research, is also involved, has successfully advanced in the ESA selection process this month, November 2023. It has not only secured its position among five applicants, alongside two others, and it now faces competition from just these two more potential missions.
