Imagine if you spent 10 years building a really expensive summer house and right after it’s complete, you got rid of your only way of getting there, your car. You were planning on bumming a ride from your neighbor down the road, but their car just blew up. Now you have no way to get to your fancy house. Oh yeah, you also left some of your buddies at the house and they’re going to run out of food soon.
That’s the current state of the U.S. space program.
