Yesterday was going to be an exciting day after my son managed to get tickets to watch the final launch of a ULA Delta IV Heavy rocket from the closest viewing location on Titan Causeway, 1.5 miles from the pad. The view was fabulous but, unfortunately, the launch was scrubbed due to a pneumatics issue just moments before lift-off. It’s been rescheduled to next Monday which is after we leave so we’ll miss out on the fireworks after all.
For the technically inclined...
