and we could have a traffic jam around the moon because elon musk has his falcon heavy. we have two beaster rockets capable of going to the moon, and after that we're going to mars. mars does have gravity, about 30% that of the earth. atmosphere about 1% of the earth's atmosphere. we have to have a base that protects us against radiation, we have to create bioengineered crops. >> it's possible. potatoes. >> that movie "the martial" cost $100 million. the indians sent a probe to mars for $70 million. you realize, hollywood movies about mars cost more than going to mars. they should give an oscar for the best-supporting spacecraft. >> technology is making it more plausible. >> cheaper and more plausible, right. >> what about overcoming the time and distance part. let's say we're thinking beyond the closest star, 100,000 years closer than that. >> now yeawe're talking about t next century. nasa has the 100-year starship program, where it's looked at fusion rockets. technology that we don't have today, but in 100 years' time, there's nothing in the laws of physics preventing

about elon musk and his company spacex's incredible launch yesterday of their rocket called the falcon heavyeers and applause ) the launch was amazing to watch, especially when the two boosters actually reentered the atmosphere and landed back at the cape in synchronicity. it was the happiest anyone has ever been while yelling, "look, the rockets are headed straight towards us!" ( laughter and applause ) but-- "and the tanks are coming down the road!" but the part i can't get over is when the rocket deployed a red tesla convertible with a mannequin in the driver's seat, blasting david bowie's "life on mars?" that is just cool! and i poke fun. you know, we made some jokes about it yesterday. but i-- when i got home, i looked at the live feed from starman, which is what they call it behind the wheel, and what i wasn't prepared for is how breathtaking this convertible would look as it cruised by the earth. that is an actual feed. it's so surreal and moving to see something that ordinary floating in space. i literally watched it for hours. whoever bullied elon musk in high school, thank you.

in my office, last month the falcon heavy rocket he launched with tesla into space in the rocket componentes again. that was everyone in the office gathering around computers watching this live stream. it is incredibly exciting. if that is his goal to bring attention to space in a bakery people, he certainly succeeded in not. charles: everyone is socially conscious these days and there has to be a social positive component for mankind in the environment. have they been able to make the environment that these trips are worthwhile? it costs a lot of money people question at the end of the day be on the surface atmosphere of it, is there a legitimate reason for these things? >> one thing he said in the event of a catastrophe befall it merits, that heavy human colonies on other planets would allow humanity to survive in some way. frankly, the easiest way to save humanity is to fix problems here on earth, not to colonize. a very hostile planet. another benefit is the private sector in space is growing and last year invested billions of dollars in it. the idea is that you could have maybe touris

just a month after successfully launching his falcon heavy rocket, the world's most powerful spacecraftrout idea -- going to mars. >> we're actually building that chip right now. >> reporter: and he plans to start very soon. >> it will do short flights. short oup and down flights next year. >> reporter: musk says he kept wondering where are the hotels on mars that were promised in "2001 a space odyssey." >> they should have great bars. >> reporter: he has his own vision of a colony on mars. while it will be exciting, it will be far from easy. >> for the people that go to mars, it will be far more dangerous, difficult, dangerous, good chance you will die. >> reporter: here on earth, musk is developing the hyperloop, an underground vacuum tube that might be able to transport people and cars from new york to d.c. or l.a. to san francisco in less than an hour. and he has strong ideas about how it would work. in a series of tweets, musk writes, the hyperloop will prioritize pedestrians and cyclist over cars. if someone can't afford a car, they should go first. musk has a gift for combining p
