Former Nasa Ames Director Scott Hubbard recaps Space X's recent launch of its resupply mission to the International Space Station. As current Chair of Space X's Safety Advisory Board, he talks about the private enterprise's attempts to land its rocket in tact after the successful launch of its cargo capsule.
"If you can have a reusable vehicle, a reusable capsule, then you can lower the cost and make space even more accessible for a lot more experiments and a lot more people. That was an amazing experiment. They almost made it."
