How many times Falcon 9 can be reused?
Company officials previously said that reusing a first-stage at least ten times significantly reduces the cost of spaceflight. A Falcon 9 booster can be reflown up to 100 times with refurbishment in between flights.
How does a Boostback burn work?
The boostback burn has to kill all forward velocity, then accelerate the rocket on a parabolic trajectory towards the landing site. They did this to test the boostback burn without having the stage land on Cape Canaveral (which was considered too risky for the early landing attempts).
How much money does SpaceX save by reusing rockets?
The Space and Missiles Systems Center last year modified the contracts for SpaceX’s next two GPS III satellite launches to allow reuse, a move that the military estimated will save about $64 million.
Does SpaceX reuse second stage?
By late 2014, SpaceX suspended or abandoned the plan to recover and reuse the Falcon 9 second stage; the additional mass of the required heat shield, landing gear, and low-powered landing engines would incur too great a performance penalty.
