Could. Just looking at the same stuff. The same rocks.
I wish we had more of it too. But really, it’s becoming impractical.
If we are serious of ever, ever traveling outside of the solar system then we should be out there right now. Researching things on Mars, learning how to live on an inhospitable planet. Grow food, filter air, and recycle the same amount of water we went up with, etc.
Because if we don’t the first mission “out there” is going to be a ginormous bust.
I think we should have built a base on the moon and been doing a lot more research into faster propulsion systems.
As long as NASA is on the original mission of exploration (Pathfinding and prospecting) I wish they had the budget of welfare.
