SpaceX is again at the cusp of securing a historic milestone as it attempts to launch NASA astronauts into space for the second time following Wednesday’s postponement of the manned mission. Should the latest endeavor succeed, SpaceX will have marked the resumption of human spaceflights from the continental United States after a hiatus of almost a decade following the shuttering of NASA’s space shuttle program back in 2011.
As a refresher, SpaceX and NASA had decided to postpone the scheduled Demo-2 test flight of the Crew Dragon spacecraft on Wednesday owing to the inclement weather conditions. This was a probable eventuality given that the U.S Air Force 45th Weather Squadron had pegged the probability of a violation of weather constraints at 50 percent.
The launch of the SpaceX Crew Dragon spacecraft is now scheduled to take place at 03:22 p.m. EDT (19:22 GMT) from Pad 39A at NASA’s Kennedy Space Center in Florida.
The latest weather prognostication from the 45th Weather Squadron paints a picture that is quite similar to the one on Wednesday. Again, the probability of violating weather constraints – including flight through precipitation, the thick cloud layer rule, and the cumulus cloud rule, associated with the frontal boundary – stands at 50 percent. This means that there remains a 50 percent probability that the SpaceX launch will be adversely affected by the prevailing weather conditions. The latest Launch Mission Execution Forecast states:
“A low-pressure area is moving into the Canadian Maritimes while trailing a frontal boundary along the Atlantic Coast States. This boundary will bring pre-frontal weather into the Atlantic and nudge the subtropical ridge axis over the Spaceport. This will impede the inland progression of the east coast sea breeze and, coupled with the westerly steering flow, push inland convection towards the Space Coast. The morning sounding shows instability in the moderate range, meaning the convection may hold off until after T-0.”
Apart from proximal precipitation and lightning, a sustained wind of 30 mph or more at 162 feet above the launch pad will also result in another scrubbed launch.
