SpaceX block 5 reusability results better than expected which could mean costs could eventually drop in half

SpaceX COO and President Gwynne Shotwell says Falcon 9 [block 5] first stages are returning in much better shape than anticipated. SpaceX has refurbishment time down to four weeks. The SpaceX goal is still a one-day turnaround next year.

In 2017, Shotwell said a Block 5 booster could relaunch a dozen or so times. The Block 3, by comparison, had an estimated life of two missions.

A Block 5 that is reusable for dozens of times with minimal refurbishment and fast turnaround could bring the profitable costs of launch down to $20-30 million per launch.

An analysis in 2017 on Reddit of Spacex costs with ten reuses suggests SpaceX could maintain profit margin with costs that are about 40-50% of a non-usable Spacex flight.
