SpaceX's Falcon Heavy center booster lacked ignition fluid to re-light engines
> Those two boosters, which were used in previous launches of SpaceX's workhorse Falcon 9 rocket, will not be reused again, Musk said in a post-launch news conference last week.Why did SpaceX spend resources to get them to safe landing then? I presume, they rather maintain their routine and maintain the success of landing the booster. It would probably be expensive to change their standard procedure.Does any know how many times a booster can be resued? What dictates its lifetime?
