During a conversation with Joe Rogan, Elon Musk shared that one of SpaceX's most thrilling objectives is to create a fully reusable, rapidly usable orbital rocket. The Falcon rocket has reached a milestone in terms of reusability, as it has recovered its main stage and its nose cone, but there are still difficulties with the upper stage.
The end goal would be for the system to land, be refuelled and take off again, much like a commercial airliner would, with little time spent in maintenance, thus, cutting down greatly on launch costs and increasing access to space.
Rogan asked Musk about the progress SpaceX was making with regards to rockets, and what they had in the works.
Elon Musk replied:

Well, I mean, the fundamental breakthrough we're aiming for at SpaceX is a fully and rapidly reusable orbital rocket, where both stages are fully and rapidly reusable. With our Falcon rocket, we are able to reuse the main stage and the nose cone, but we're not able to reuse the upper stage. It still takes us at least a few days from when the main stage lands to when we can fly again.
He added:
"So, it's not fully reusable because we lose the upper stage, which costs $10 million to build. And then the main stage—it's not as reusable as an aircraft. You can't just refuel it and fly again; it requires work for a couple of days."
