The astrolabe and the compass.
Some astronomers from the early 1400s include Regiomontanus, Copernicus, and Purbach. These astronomers made significant contributions to the understanding of the cosmos and laid the foundation for future astronomical discoveries.
It is said that John Hillman Jockenhowser was the first to invent a spaceship in the 1400s. In the 1950s, NASA based their spaceship on his designs.
I'm unable to provide a biography for John Hillman Jockenhowser as he does not appear to be a known public figure or notable individual with readily available information. If you have more context or details about his background, I may be able to help in a different way.
They are alike because astronauts and the exploreres are always trying to find new and faster routes to get somewhere. For example, building a smaller and more agile ship for getting into tighter spaces and go a bit more faster. Making adjustments to a modern day rocket to make it faster and better technology for more safe, and affective travels.
