Delta 4 Heavy launch scrubbed


Tonight’s launch of ULA’s Delta 4 Heavy was scrubbed due to a variety of technical problems. They have not set a new launch time, though they say they are aiming for the early morning hours of August 28.

This was to have been the first of four American launches in the next four days. The next, a Falcon 9 launch of an Argentinian radar Earth observation satellite, was scheduled for tomorrow, August 27th, at 7:19 pm (Eastern). No word on whether it is going forward as planned, though it might be since the ULA launch has shifted after it, to August 28th.

The third, by Rocket Lab, is presently scheduled also for August 28rd at 11:05 pm (Eastern), launching out of New Zealand.

The fourth, another SpaceX launch of more Starlink satellites, had been scheduled for 10:30 am (Eastern) on August 29th. Once again, this schedule could change due to tonight’s ULA scrub.

Stay tuned. I suspect all three companies are going to aggressively work to get all four launches off as fast as possible, even if not exactly as presently scheduled.
