Experimental robots on the moon, paving the way for extraterrestrial refuelling stations and for astronauts "living off the land". Commercial space taxis ferrying crew members to and from the International Space Station, while a "plasma thruster" - a precursor to engines that will eventually send astronauts to Mars - undergoes tests in space.

All this could be happening a decade from now, following a change of direction for NASA signalled by the White House last week.

He also reckons that commercial space companies are finally ready to take the strain when it comes to transporting NASA astronauts.
