Forget Mars, Trump Wants NASA To Visit Jupiter’s Moon Europa And Explore The Solar System

My question is great, but shouldn’t we try getting to the moon, Mars first? We aren’t supposed to be looking at Mars until 2030’s at a minimum, so how long to get out to Jupiter? Plus, how to protect humans from radiation? Jupiter has very high radiation levels, even more than moon out Mars. And where is the money coming from? Just my two cents.
