Next stop, the year 2022 and a colony on Mars!

Psi:
Speculation is that the relight of the booster engines happened without stable acceleration to keep the fuel from floating/sloshing around in the tanks and many engines inhaled air and exploded. Resulting in an inability to continue the booster return and water landing mission, which triggered FTS.

Before that, we must stop in 2017 with the first crewed flight test of Boeing Starliner...

For 2x the money that SpaceX received for Crew Dragon.

The launcher not only has to take on board enough fuel to insert the payload into low earth orbit but, the stages need enough fuel for the soft landing return. This makes for a 'dead fuel weight' overhead on the way up. Maybe the engineering horizon for this added mass is too far away at this scale?
A fully reusable launch system might be 'green', but cannot be sustainable when confidence of delivering an expensive payload /personnel into orbit is currently less than zero - despite all of the optomistic hollowing and whooping from the Muskovites every time the glue comes unstuck.
On a side note, I recently heard the Nasa versus SpaceX dynamic being described as, "it's rocket scientists versus space cowboys." Yee har...
