"NASA’s hunt for extraterrestrial life within our solar system is set to continue with plans to send a robotic landing craft to drill into Jupiter's icy moon Europa in search of life." -RT article
I think this is interesting, if we find life on Europa it would be incredible. This will not happen until many years, but it will happen in our lifetimes which is fascinating, it will be like going to the moon again, except this time it's Europa. But even if we don't find life, we can still go to Mars id say by the 2030's or 2040's.
Here's a quick interesting video which is from the article.https://youtu.be/kz9VhCQbPAk
