25 years after the Challenger disaster, where do you want the space program to go?

We as the human race who claim to own the earth will eventually either become extinct or have to find another inhabitable planet due to the expansion and heating up of the sun..though thats a long time off..therefore in theory space travel and exploration remains important ... however it doesn't come Cheap...but what price the survival of us when its in our nature to destroy those around us who don't conform to our ideals or beliefs
