A person after whom a space telescope or probe is named

Our answer book holds 40 answers to “A person after whom a space telescope or probe is named”, from the first thing anyone would say to names almost nobody would think of. Edwin Hubble, Galileo Galilei and Johannes Kepler are what most people type first, so they score the least. It is a fairly short list: only 8 answers sit in the two rarest tiers, so reaching one takes real knowledge.

Space questions reward anyone who remembers the names behind the famous missions, not just the missions themselves. You will find it in stage 37, “Big Brains”, of the Cosmos mission. The first stages of every mission are free, and later stages come with the full mission.
