A long and hot Thursday afternoon spent waiting for the launch of the first SpaceX Falcon 9 Block 5 rocket. Reportedly the last iteration of the Falcon 9 and one promising rapid reuse of its first stage booster from upwards of ten to a hundred reflights. This particular rocket is supposed to carry Bangabandhu Satellite-1, the first satellite for Bangladesh and the large contingent of dignitaries and guests from that country seemed very enthusiastic for the launch. An attitude that was quickly dampened by repeated delays and then a scrub at one minute due to the booster calling an abort on its own systems. Safety first but, still, a disappointment and a 24-hour delay. The image shows gaseous oxygen venting from the Launch Complex 39A launch tower during fueling. The rocket is hidden behind the gantry from this angle.
