After being captured, will you be able to gather resources in only 3 days to fight back?

Even though you almost died on an alien planet, and had to fight off an apocalypse, you decide to finish your original mission. It was to go far out to a planet that has a very rare, but very powerful ore. Nothing like it can be found on Earth.

The amount of fuel on your ship has been checked by over 50 people, to make sure that you do not run out again. You also have much more technology, and will be able to hear what your partner on Earth is telling you about the planet, even though you can't talk to them.

All you have to do is mine deep underground into the planet's core, get the ore, and come back home. It should be easy, unless something bad happens...
