This is in the collection, The Complete Robot.
This has hints of The Medusa Chronicles in as much that it has a wonderful descent to the surface of Jupiter.
So the humanity, spreading out into the solar system has encountered intelligent life on Jupiter, and that intelligent life doesn’t like lesser lifeforms poluting its environment.
So the humans on Ganymede decide to send three robots down to have a chat with the locals and see if they can make peace and live happily ever after.
Next up in the Robots is, Stranger in Paradise.
