Shot to the Moon
I don't get why there are no more missions toward the Moon. Being (relatively) close, it is 'easy' and fast to send a rocket to there. Why is there no mission to test automatic rovers with advanced capacities, to discover what the lava tunnels and caves look like, to experiment 3D printing to built housings, to install telescopes (traditional ones)... Shouldn't be the Moon an experiment field before Mars?
