>> >> and the lots of research. >> before we get it into your book callback to the of football field of spending years and wrote was that about?. >>

>> >> our dna tells the story and what does that mean?. >> data lot of animals that migrate large distances to travel the plan in search of food or beating -- meeting but traveling out of curiosity spreading out of africa and across the planet they are startlingly? there was the bridge you could walk across town to patagonia.

so it was curiosity that they spread across the planet with the desire to explore even the explorer jean taking that behavior with those that might associate so then you have to go up and out to. >> is that looking at a horseless carriage? even in hindsight. with the gallup and other polls that they think is the hoax. but that was close to half a century ago.

but on the other hand, it is the biggest that humans have ever achieved. with the enormous amount of money. one hundred times more powerful than your cellphone. but yet it was so long ago. >> and with those different aspects. >> it is critical is the government:so the budget soared during the apollo bin surge quickly. and equally discouraging with the federal budget so that has to do more with

less with the technologies but now there were all those new players. and some are funded by billionaires' but i think in the aggregate clearly day rival the budget. >> are they cooperating with each other?. >> with nasa i think there is some frustration it was by a retired so some of the companies wanted to do their own thing. so there was suddenly a rivalry but until recently there was cooperation with

these private space companies they aren't a business model yet. with those multibillion-dollar contracts putting astronauts up into orbit and the money is important to them. and hasn't been able to over six shears. -- years also nasa tries to be more nimble not that that love will love space-x but the micro satellites so nasa is trying to learn and rollout of punches. >> host: you mentioned the university?. >> yes we have been

contacted twice to be at the launch itself that goes to the martian polar region that will snag an asteroid. >> beyond a teacher in space to write about that. >> so to get the glitter is your eye is a valuable commodity. that happens to be coming year the you could capture with to a trillion dollars worth of precious metals those a revival of the semiconductor industry with those that are out there and available how you tether them into a safe for a bit then harvest that mother

lode that the economic level without destroying the market. >> bb five for 10 years. >> was a time to retire the space shuttle?. >> absolutely. >> at all data never went up more than once a month in history when then those lost catastrophically it was devastating to the space program that was long over due to retire. >> maybe not for the international space station because scientists have not flocked to winning companies had not flocked unless heavily subsidized with that

economic and research activity but said demonstration we can work and live in space. and the superpower rivals with cooperation and living in space all the up practical stuff it isn't very glamorous like plumbing but with $120 billion. >> george w. bush is that important to you?. >> is said bin flow and is very disappointing especially after we are back but it is a good place to live and work in space the

moon is a very good place and with a self-sufficient colony because the of lunar soil is extremely sterile -- sterile. and then turn that to rocket fuel so free want to learn how to live beyond and serving as a staging post. >> with your book "beyond" our future in space" where would you like us to go?. >> the outer solar system is more ambitious with jupiter and saturn are so interesting. that could well be the next place and with those are

quite fascinating it is a more expansive move proposition. >> is there life in your view beyond?. >> yes. and billions of galaxies in the universe. the party much there are billions of earthlight planets within our own galaxy. but nothing has happened so yes i believe there is life out there. >> so but about space exploration?.

>> that is beyond my means but i would like to experience that i have talked to enough astronauts to be jealous the pipe dream for the whole activity in go into jupiter or saturn. electronic technology the with the propulsion technologies and headed to the stars to be extraordinary. >> of nasa of has resuscitated and last year to send and robots in now hosting conferences with the

propulsion systems and now they aren't doing it again. so yes phils are all moving forward. >> where about those students taking courses online?. >> 100,000 is a lot but it isn't outrageous you are tapping though whole world and 70 different countries rather than marching like of a textbook i give them the good stuff and the axle plant it did tell them how we make telescopes are measure black calls. and with those cutting edge topics. and we have good of my

discussions. >> your book "beyond" is a trade title. >> yes i have written textbooks and technical articles in my career. and to explain that to read general audience so would i buy about cosmology of those that challenges you to know your subject well. so science is important now more than ever i of extra motivated. >> host: chris impey book is called "beyond" our future in space" professor of astronomy at the university of arizona.

. >> and digest got lucky. . >> my political history was i tell people born in 1946 in the stamp at democrat on your birthday of forget. and then to change parties. >> there were no jobs in information security. many people in the of military this was a hobby
