      Static fire targeting 1800 Eastern

      SpaceX is expecting the F9 B5 firststage will do up to 10 flights between refurbs, and they'll soon be flight testing second stage recovery. Payload fairing recovery is already in flight test.

            SpaceX ✔ @SpaceX
            Falcon 9 Block 5 and Bangabandhu Satellite-1 went vertical on Pad 39A in Florida this morning. Now targeting liftoff at 4:42 p.m. EDT, 20:42 UTC – vehicle and payload look good, completing final check outs at the pad. http://spacex.com/webcast

              Standing down today due to a standard ground system auto abort at T-1 min. Rocket and payload are in good health teams are working towards tomorrows backup launch opportunity at 4:14 p.m. EDT, or 20:14 UTC.

                It ended up launching the 11th. Video below.




                I've been reading about the Falcon 9 Block 5. If they can pull off a 100 flight rocket with 10 flights between maintenance checks that's going to completely change the space flight game. His BFR as an international shuttle suddenly seems more feasible.

                    Perfect flight from a payload delivery perspective. No word yet on actual Block 5 performance metrics. Successful stage one landing at sea, no fairing recovery or second stage recoveries were attempted.

                      I couldn't get on for 2 days or I'd have posted an update.

                      So far the performance looked very good. Now comes a few weeks of tearing it apart to make sure all the expectations were hit, then a series of reflights.

                      IIRC they're down to just a few Blocks 4's due to a clearing of landed inventory.

                        Teslarati.com photogs took some good shots of the landed F9 B5 booster.

                        This reentered at 2 km/sec after a Geostationary launch, which usually leaves boosters extra-crispy with a thick layer of soot.

                        SpaceX’s first launched and landed Falcon 9 Block 5 booster has returned to port after a handful of days at sea, hopefully marking the beginning of a long and storied future of commercial missions. The booster – numbered B1046 – appears to be in extraordinarily good shape, more or less unscathed after a relatively high-energy […]

                        Also updated is Octagrabber, the 4-armed giant robot which scoots out of its doghouse after a landing and secures Falcon 9 to the droneship so it doesn't slide or tip over in high seas. The Octagrabber's arms grab attachment points on Falcon 9's Octaweb armored engine bay.
