space station for nasa. >> i imagine you lower the costs down and suddenly you're talking reusable vehicles, that alone could ignite interest in space and remove what is typically been a huge cost barrier. >> yeah. the barrier has been cost. every town that nasa would launch for the space station would cost $10,000 a pound. so if musk can drop that by a factor of ten to $1,000, it opens up the idea of space hotels or research labs, new use for space and industry that haven't been available just because of the cost barrier of getting up there. so that's a promise here. >> musk says factor of 100. that might be a very good salesman talking. >> maybe so. >> what i'm wondering is whether the implications beyond just sending supplies up to the space station or short hops, beyond that. what do you think?
