The aerospace agency revealed the issue in a Tuesday post that explained recent telemetry from the craft suggested all its systems were working as intended.
After NASA received that data, MAVEN swung behind Mars, and therefore lost contact with Earth as its radios can’t send data through a planet.
But when MAVEN’s orbit brought it back into view, ground stations on Earth could not detect any signal from the probe.
NASA doesn’t know what’s gone wrong.

It seems to do a quarter turn to its left at the end. I wonder if this is intentional or not.
