eventually we do want to go back to the moon, perhaps mars or an as roid and we are -- asteroid and we are going to need to stand down and take time and perhaps the money that was used to operate the space shuttle and instead build a new vehicle with it which is what we plan to do. >> exciting to hear that we intend to go back to the moon and mars. what would you say is the most significant contribution that the shuttle program has made? >> i can definitely offer you one. i think there were a number of great contributions the shuttle made but we are here talking to you from one of the crowning achievements of the space shuttle program and that's the international space station, you know, the shuttle was integral in constructing, building and putting all this together, 210 miles above the surface of the earth. so, you know, we get to see this, you know, this work of art every day for the next several days and it will be here for years to come. so definitely the space station is probably one of the greatest achievements of this space shuttle. >> well, we love you, we are pleased to talk to you. final question, have you thought of a neil armstrong- type statement to ma

when human beings go to mars they are settlers there colonizers it is very difficult very challenging to bring them back again we don't have the fuel we don't have the engines. and i use something that's very well understood by people in america that the pilgrims on that ship called the mayflower that left from england and came to the shores of the united states of america they did not wait around the landing place for the ship to take them back they came here. on american soil to live the rest of their life and so will the human beings that leave the earth become the pioneers the settlers the colonizers. we need them there we need more of them there too to sustain a colony you can't do that with just six people twelve people twenty four people you need sixty you need one hundred. they're valuable where they are don't bring them back. to get in a rocking chair and write their memoirs they can write their memoirs from the surface of mars thank you very much for this interview. forty two thousand americans die each year for accidents will be a thousand. seven hundred thousand people murdered and thirty two thousand will kill themselves cancer in all its forms kills five

doug hurley, talk about how america will continue to explore but how and where because while george w. bush had envisioned us going back to the moon and mars and beyond, this administration has decided to end manned space flight. going forward from now on if we want to ride up to the international space station, we're going to have to write a $65 million to the country of russia. >> and have 55 astronauts learn to speak russian. rejoining us tom jones and phil keating and welcome everybody else who just got up. we just witnessed the end of the space shuttle program and of course, on our couch, wide to the right, dr. manning. >> yeah,>> tom, let's start with you. you've been on the space shuttle. it sounded to me like the voice of nasa himself, his voice actually cracked a little bit when he said the mission at its end. this is a tough day. >> it is. and i don't think i've still gotten my head around the fact that we're not going to see these wonderful ships fly again. in order to free up funds for what comes next at nasa, they've decided to retire the space shuttle, space station complete in terms of its assembly so now it's moving on to t
