Reusability of the first stage of a rocket to orbit or beyond.

Reusability.

Conversation with Bob Zimmerman. he keeps the website behind the black.

Reusability again and again is the SpaceX Advantage.

Bob here tells the tale of how much reusability means for SpaceX's success

and also for the anticipation that all spaceflight can become as routine as SpaceX now makes it appear, almost as if they

have a fleet of commercial aircraft that can use again and again and again and program them in and cut the price and out-compete the other states and the other

companies until everybody adopts reusability.

Here's Bob Zimmerman to apply, more of this later.

Yeah, this is good news.

SpaceX, as we all know from almost a decade now, has been using, reusing the first stages on the

Falcon 9 rocket repeatedly.

And they've been upgrading that first stage as they go to a point where they say the first

stages they're using now could easily fly 20, maybe 30 times.

But up to now, none of them have flown more than 19 times.

They've got two that have flown 19 times and I think one that is flown 18 times.

And then a few at 17.

Well, this past weekend they launched another 23 Stalling satellites and the

Falcon 9 that launched launched with a first stage completing its 20th flight a new

record and it landed successfully completing its 20th flight, a new record.

And it landed successfully, so it could fly again.
