How many GB is Satan is an Astronaut?

2 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

A woman who suffers from severe delusions wakes in the center of a forest aboard “The BUB,” a proto-generation ship from the mysterious Faust Corporation. Waking to a vision of a spirit she grew up with, she quickly learns that not everything is as it seems, and this waking cycle is anything but ordinary.
