Decline of the Ancient Mariner (audio story)

 was the third story of the tenth season of Big Finish Productions' Short Trips series.

Publisher's summary
When NASA has a problem they can't quite understand, they quickly turn to the Doctor and Sarah Jane Smith to investigate. Their Mariner 10 probe disappeared for 30 minutes, with no apparent explanation. What starts out as quick investigation ends up having catastrophic consequences for the time travellers.

But the reason for the probe's disappearance sounds a little too familiar for the Doctor...

 * The Doctor jokes that Sarah "expects 1974 to be a time of equality".
