Raumfahrer.Net Neuigkeiten<p>ESA-Mission “Ramses” zum Asteroiden Apophis<br>Vor 30 Jahren, am 16.07.1994, beobachteten Astronom*innen voller Spannung, wie Bruchstück des Kometen Shoemaker-Levy 9 in den Jupiter einschlugen.

Continued thread

We now bid adieu to OSIRIS-REx. But we will meet again, around April 13, 2029, when it will perform a close encounter with asteroid 99942 Apophis.

It's new name is OSIRIS-APEX.
APEX = Apophis Explorer

Have you noticed how NASA spacecraft are such over-achievers? 😎
