How do satellites leave the atmosphere no problem, but burn up when they come back in?

I just saw a link to an article about the Japanese designing wooden satellites so they burn up on reentry and reduce space junk, and it made me wonder how they get out of the earth’s atmosphere without being destroyed.

They go in rockets broseph.

When a satellite eventually gets decommissioned or replaced, it’s sprung away from the earth magnetic pull hence why it becomes space garbage.

If they make the satellites out of wood the earths magnetic pull can bring it to earth and let most of it burn up.
