I think there's just one way to do that, to do more! We need an ambitious goal for what to do after the International Space Station. The current Director General for ESA is clear in that he want us to go back to the moon with the plan to build and scale a lunar base. I agree.

Anyways, it is events like the successful launch and landing of the Falcon Heavy that SpaceX did which really gets people excited. Not presentations held by astronauts.
