Nasa’s Mars Rover Opportunity Concludes a 15-Year Mission

They designed it for a winter which means at least 687+ earth days days was considered achievable. Dust was expected to be a larger issue and in many ways they lucked out, but more so as a calculated risk than blind luck.

Distance makes little difference past the first day. Doing the same thing on the moon would not be easier becase it’s closer. It’s local conditions that make this hard more so than simply getting to that point.

I can assure you that the distance took its toll on the rovers, in my understanding. Their wheel surfaces eroded, oil pumps failed, bearings degraded and they ended up dragging dead wheels in the end.

Are you talking about the distance the rovers traveled while on mars? Because that's not what Retric is talking about. Retric is talking about the distance from the earth to mars (hence why they compared it to the moon).

Ah, my mistake; I misunderstood their comment.

To me, that they designed it to last that long, and it actually did, just makes it more impressive. Otherwise it would just be blind luck.
