SpaceLaunchWeather willing, there will be a countdown and launch of the SpaceX Crew Dragon (CNN, MSNBC, Fox News, 3 p.m.). The Demo-2 test flight was to have launched Wednesday but was delayed due to lightning near the Kennedy Space Center. It was rescheduled for today, when there ought to be an even bigger audience (on TV only; it’s not open for a public launch viewing). Even the ,broadcast networks will probably run it, since they have no live sports to show anyway. The actual launch, the first for a U.S. spacecraft in nearly nine years, since the final flight of the Space Shuttle Atlantis in 2011,  is scheduled for about 3:22 p.m. And if it has to be postponed again, they’ll try once more Sunday at 3 p.m..
