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.
