Amusing, considering I was bashed last night with repeated "you can't patch it once it's on Mars".

- raverbashing 14y agoOnce you build an "over the air" upgrade capability and a fail-safe mode (unlike my Android phone, thanks for nothing G & S) you can do it But the software, as far as I know, is very modular, so this could be only an upgrade of some modules Edit: by RTFA this looks more like a replacement rather than an update, like, making usage of all the landing software space since this is not needed anymore.
- tsotha 14y agoSpirit and Opportunity were upgraded as well.
- dlokshin 14y agoWhen they took off, the autonomous navigation wasn't even close to complete. They pushed that software once the two Rovers were already on Mars. (I was working on the Rover team at the time)
- shaunpoore 14y agoI was gonna say the only reason I can think of to not load the software before it takes off is because it isn't finished yet. I'd imagine memory is pretty small/inexpensive even if it has to be specially fitted to get blasted across the solar system and work next to a nuclear power plant.

- EternalFury 14y agoThat is beyond amazing.
