Any idea how much storage it has? I would think it'd have to be TBs to store all these images, logs, and other data for years while making sure they have enough

Any idea how much storage it has? I would think it'd have to be TBs to store all these images, logs, and other data for years while making sure they have enough memory so that they're not limited and if the rover stays there for longer than intended.
- Hnrobert42 6y agoWhy would it need to continue to store things after successful receipt on Earth?
- leephillips 6y agoVery off-site backup.
- azernik 6y agoOnce it's been sent to Earth, they drop it. Curiosity's main computer had a flash drive of 2GB, and each of the big cameras had an 8GB flash drive on board. I doubt Perseverance is much changed from that; the main computer is IIRC a spare part from the Curiosity production. Rad-hardened computer hardware is expensive and bulky. You don't add storage or processing power that you don't absolutely need.
