At present, NASA is planning a mission to Europa, to try and assess its habitability. An argument might also be made for Enceladus, however.
Let's imagine you had to pick one of those moons to send an uncrewed (i.e. robotic) mission to. The spacecraft will probably orbit the giant planet (Jupiter in the case of Europa, Saturn in the case of Enceladus), and make many flybys of the moon you're studying.
Which moon would you pick, and why? The goal here is to briefly discuss the pros and cons of each moon as a target for a mission. You don't even have to have a strong preference either way, just lay out a few pros and cons for each.

Breaking this into a few short paragraphs will probably be a good idea
If there was a planet orbiting a first generation star, which planet in our solar system would it resemble most? Would it be likely for such a planet to have life?

- There is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the surface of Europa. One way to do this is to put the lander at the end of a rotating arm in an orbiting earth satellite.arrow_forwardWhat is the Oobleck fee? And what are its benefits? And what are his tools?
