NASA's mission to send a landing probe on Europa and have it drill through the ice layer (if its as thin as some speculate) seems to have been put on a back burner. Ive been trying to understand why everything is focued on the Ares rocket. The VASIMR technology is said by many to be the next step, instead NASA seems to be going backwards. VASIMR has its critics, but there are a large amount of propulsion experts that see Ares as nothing new, except the higher price tag.
The probe wouldnt require a human operator though, I dont know why it has been set aside.
I hope to see a Mars expedition in my lifetime. Even a moon expedition, the last happend before I was born.
