I don't get it. Are rovers only assigned certain amounts of time to be implemented?
The Mars rovers were sent with no designed way of returning home. They don't work in shifts because they are robots. They work, they accomplish the goals we had set, and then they sit there.
They aren't capable of thoughts like this. If it was a human, there would be a plan to bring them home.
how the forget did his battery last for 2000 days
Solar power + rechargable + the fact that the rover is ultra-low voltage. Most space components operate at very low voltages, we're not sending Sandy Bridge Core i7's at 3.2 GHz or anything, because they would heat up so much in space. Since space has no air, there's no way to cool them off at all.
he's saying that his power is dying. Which may mean he can't have a solar panel, or else he would not be running out of power
There is a point where batteries can stop recharging though. Laptop batteries are a great example, after long periods of usage their battery life will become smaller. I had a laptop with a battery life of around 3 hours. Within 2-3 years, ran down to 30 minutes to barely a few seconds until it was useless.
