the entire freaking planet is a hell hole.

some points to consider- it's extremely hot.

like melt-the-probe kind of hot.

the atmosphere is extremely dense and at the surface has extreme pressures. like shrink-the-cute-styrofoam-head-outside-the-submarine pressure.

oh, and it rains fucking sulfuric acid.

what's hilarious is, early on they thought she was the sister planet to earth, because gravity was similar, rocky world with a similar orbit to earth....

and then we sent probes there and the probes kept dying.
