A Falcon 9 rocket has gone vertical on Thursday morning at Launch Complex 39A in Florida, and SpaceX is on track for the liftoff of a brand-new version of its workforce booster. The launch of the Bangabandhu Satellite-1 to geostationary transfer orbit is set for 4:12pm ET (20:12 UTC) Thursday, with a launch window that stretches for a little more than two hours.
The highlight of this flight is the debut of the Block 5 version of the Falcon 9 rocket (which Ars previewed thoroughly last week). SpaceX founder Elon Musk has said this will be the final “substantial” upgrade to the Falcon 9 rocket, optimizing the booster for reuse. The company hopes to be able to fly each Block 5 first stage 10 times before significant refurbishment is required.
Ten flights of an individual booster would be hugely significant, as SpaceX has thus far only ever reused each of its Falcon 9 rockets a single time. Additionally, the company hopes to reduce the turnaround time between launches of a Falcon 9 booster, now several months, to a matter of weeks.
