What an amazing sight it must have been when New Horizons visited Pluto. We need to get out there.

This is imagined from 2001-A Space Odyssey, novelized version.

In the movie Discovery went to Jupiter’s moon Io, in the novel it went to Saturn’s moon Iapetus. This moon is unique in that one side is nearly completely black in reality. The monolith / stargate was in the center.

Imagined from the novel by Clifford Simak
