[20200530_203823 UTC: UPDATE: Launch was successful, all systems nominal, first stage successfully landed on the drone ship "Of Course I Still Love You", and Ben and Doug are on their 19-hour flight to the ISS (International Space Station). Live coverage continues all the way through docking.]

Today's the day— weather permitting, America is returning to space:

During Wednesday's technically smooth countdown, NASA astronauts Doug Hurley and Bob Behnken came within 17 minutes of launching before a scrub due to poor weather. Now the crew will suit up and try again on Saturday despite still iffy weather.

SpaceX is working toward an instantaneous launch at 3:22pm ET (19:22 UTC). The big concern again today is the development of thunderstorms near the launch site this afternoon, which could violate a number of weather criteria, including not just precipitation, but also residual electric energy from lighting in the atmosphere. Overall, the chance of acceptable weather at launch time is about 50 percent, forecasters estimate. They are also watching for down-range conditions in case an emergency abort is required during the rocket's ascent to space.

This is nothing new for NASA or U.S. human spaceflight. As the commander, Hurley, noted on Twitter Friday that his first space mission in 2009 scrubbed five times for weather or technical issues before it finally lifted off. "All launch commit criteria is developed way ahead of any attempt," Hurley said. "This makes the correct scrub or launch decision easier in the heat of the moment."

It has been such a long, long road for NASA and SpaceX to reach this moment—thousands of engineers and technicians have labored to design, develop, test, and fly hardware for the Dragon spacecraft and Falcon 9 rocket over the last decade. But now the hardware and crew are ready, and at just the right time, to go fly.

[...] A combined NASA and SpaceX webcast will begin today at 11am ET (15:00 UTC).

Launch is scheduled for exactly 2 hours from the time this story goes live.

    Were you just watching the news conference from the ISS by chance? You should be able to catch it by zooming through this [youtu.be] video at the tail end. I had a lot of hopes for Bridenstine and I do think at the beginning of his tenure that he was everything we need. But I have no idea how congress/Boeing does it, but they corrupt pretty much everybody. After this docking was completed flawlessly, he went on to praise this as the advent of the Artemis project, their partners for the moon program, and went on some babbling identity politics things before to finally conclude non-ironically stating that he's more popular than ever on Twitter and it's thanks to these astronauts. And that was literally his entire spiel. He mentioned SpaceX literally once, in passing.

    This is, with 0 hyperbole, one of the most important achievements in human spaceflight ever achieved primarily thanks to SpaceX, and it was Boeing + identity politics + I'm popular on Twitter. He's like an entirely different person and has absolutely checked out from everything and is just doing the real life equivalent of shit posting while peddling for Boeing. Even the astronauts seemed taken aback and were the ones repeatedly mentioning SpaceX. He managed to make Ted Cruz sound thoughtful and insightful, by contrast. No I definitely think speaking out, or really showing anything short of unadulterated love for Boeing, in this environment is as good as resigning.

    I'm looking at it. It starts at 3:13:00 in your link.
