As well as Mars Elon talks about the Falcon 9-Heavy vehicle. This rocket will be substantially bigger than the simple variant due to fly next month, and should be capable of putting more than 53 tonnes (117,000lb) of payload in a low-Earth orbit – more than twice that of the space shuttle.
Elon Musk believes the Falcon Heavy will be transformative because it will substantially reduce the cost of carrying a given mass into space – breaking the barrier of $1,000 per pound (0.45 kg) lifted.
Elon Musk is interviewed in the BBC Radio 4 show ‘Scotts Legacy Part 2’ which can be heard at http://www.bbc.co.uk/programmes/b01dhrmj
It is understood there could be some issues with people overseas listening to or watching BBC shows. The use of a Proxy Server or software such as Expat Shield may be a way around this.
