This is World News with Charles Gibson. For 27 years, the shuttle has been the US space program… the only means to get astronauts into space. “Zero and lift off.” A 125 flights so far… all in low earth orbit. And with just a few more flights scheduled, the shuttle will be retired in a year and a half. So where does NASA go next? In effect, they plan to go back to the future.

 

This was space flight 40 years ago, Apollo 11… the first time man ever landed on the moon, 1969. NASA’s plan now is to go back to the moon. And this NASA animation shows how they plan to do it. They’ll launch two rockets. This Ares Five rocket will take a lunar landing vehicle into earth orbit, then a smaller rocket will take four astronauts into orbit. The astronauts in their capsule will link with the spacecraft carrying their Lander, reignite the engine from the larger rocket and head for a 3-day trip to the moon. All four astronauts getting into the Lander and going to the moon’s surface. “We will go to the moon anywhere on the moon. We will stay twice as long as Apollo did with twice as many people, and be able to bring that crew home any time.”

 

But why go back to the moon when we were there 40 years ago? The plan is for astronauts to live there for weeks at a time and perfect the systems that will later take man even deeper into space. All of this is a long time away. The rockets haven’t been tested yet. Astronauts won’t fly on the moon until 2015 and the first time, man will return to the moon won’t be at least until 2020. “Do I wanna go? I mean, absolutely. I would really love to go.”

 

But with 10 years between retiring the shuttle and getting to the moon again, will the public continue to support space exploration and will the congress which would have to appropriate지출을 승인하다 billions to make it all happen? But for right now, that is the plan for the post-shuttle era… 2020 man to the moon! Optimistically낙관적으로 10 to 15 years later man to mars. And already the equipment needed to make that all happen is being built. This, for instance, is the rover that astronauts will use to drive around and explore the lunar surface and later, the surface of mars. I had a chance to ride in it today and drive it at NASA headquarters. It was quite a ride. And we will show it to you tomorrow.
