Scientists haven't heard from the MAVEN orbiter since December 6. It had been studying the Martian atmosphere for over a decade

NASA says it is “very unlikely” the agency will be able to recover a Mars spacecraft that has been out of contact for more than a month.

NASA lost contact with the MAVEN probe in Mars orbit, and teams are working to reestablish communications after an unexpected anomaly.

The James Webb Space Telescope is not circling our planet the way most people imagine a satellite does. Instead, NASA parked this observatory in a carefully chosen deep space orbit that lets it study the Universe with a stability and clarity no Earth‑bound platform could match.
