Grissom IV

Grissom IV features constant torrential downpours. The chaotic ferocity of these storms has resulted in the severe erosion of the planet's surface, creating strange shapes in the terrain and occasionally uncovering vast amounts of resources.

Trivia
It was probably named after one of the first American astronauts, Gus Grissom, who was a member of Project Mercury and died during a training exercise for the Apollo One mission.
