whats going to happen now to our space program after the last shuttle ?

We didnt end NASA. We ended the Shuttle program. We also ended the Apollo missions, too, long ago in fact, but NASA kept going.

Good question. Nothing's gonna happen. Until the new ones are developed, we'll be stuck. That's the reality we have to face. There aren't many things left you can actually observe, and what needs to be observed well needs time... And a lot of time... So basically we've done everything we've had to do. Sad though...
