Watching the launch of the Artemis-2 mission

The countdown for the launch of the 10-day Artemis-2 manned mission around the Moon continues, with the launch scheduled for 6:24 pm (Eastern) today.
For updates from NASA, go here. So far all is proceeding as planned. A step-by-step outline of the countdown itself can be found here.
A day-by-day detailed description of the planned mission can be found here. For the first day the crew will remain in Earth orbit in order to test the operation of their Orion capsule. To reiterate, the capsule’s life support system has not been flown in space previously, so this first day is critical. If there are any issues, the astronauts are still close to Earth and can return relatively quickly.
If no problems are detected during that first day, on day two the crew will fire the spacecraft’s engines and head to the Moon. At that point everything must function as planned for nine days as they travel out to the Moon, swing around it without going into orbit, and head back to Earth.
The return to Earth remains the most dangerous moment for this flight. During the 2022 unmanned test flight around the Moon, the heat shield design on Orion did not work as planned, with chunks breaking off in a manner that was unexpected and very concerning. NASA spent two years contemplating the issue, and decided to live with the same heat shield design for this mission, since replacing the shield would have delayed the launch at minimum two years. It has adjusted the return flight path in a way it thinks will mitigate the problem. As its engineers are only guessing at what caused the issue and could be wrong — having done no real life tests — we will not know if they are right until Orion splashes down.
We must pray that they are right.
I have embedded NASA’s live stream below, which will begin shortly.
