A returned Falcon 9 first stage has been test fired at SpaceX’s McGregor test center, in what is the start of a series of firings. As of late August, several firings have taken place. F9-S1-0024 returned home after helping push JCSAT-14 uphill earlier this year, prior to landing on the ASDS located in the Atlantic Ocean. Although this stage isn’t expected to fly again, it is involved in critical ground testing, which will pave the way for the first relaunch of a Falcon 9 booster.
