TL;DR
For the first time since 1972, humans will get close to the Moon again.
The Artemis program in the US aims to return to the Moon, land, and work on long-term expeditions and a permanent Moon base. At least for initial missions, astronauts will launch in an Orion capsule on top of the Space Launch System (SLS), and return in Orion. SLS and Orion made a first uncrewed test flight (Artemis I) in 2022, now it's time for a crewed test flight. It will only fly around the Moon once in a free-return trajectory without landing, but it will still be the first time since 1972 that humans leave low Earth orbit and go to the Moon.

Currently everything is on track for a launch in just under 10 hours. NASA is preparing the rocket for propellant loading. Countdown plan

There is a 2 hour launch window each day for the next few days in case something leads to delays, NASA currently aims at the start of the first launch window. The crew will make one orbit in low Earth orbit, then raise its orbit to a highly eccentric orbit that needs one day for a revolution, and if nothing goes wrong it will then commit to fly to the Moon and back, which takes about a week.

Is this a live channel that I can tune in to? It's 6 hours along and does not seem to be live footage. Or maybe it will be after the red carpet pre-show?

CNN is carrying it live on TV (I'm in the US).
 
What are the blue pouches in the armpits and on the ankles of the crew's suits? My Google-fu is failing me...

They switched to a new URL.

Hold at T-10 minutes, so far things look fine.

Edit: Go for terminal count, last 10 minutes started.

I believe they are the built-in flotation device, one part of the many subsystems in the Orion Crew Survival System suit. I am not entirely sure about the blue leg attachments, but would venture the guess that they are bag containing survival gear for use after splash-down.

Regarding searching for info, try "orion crew survival system suit schematics".

Edit: added missing "system" to list of search terms.

Apogee raising burn is in progress. This will give them an orbital period of one day, enough time to fully test everything before committing to go to the Moon in 24 hours. There was a lot of discussion about the toilet status but it doesn't seem to be a major issue.

Timeline, updated for an April 1 launch.

NASA's website tracking Orion - seems to be a bit buggy, not all features work for everyone, but at least telemetry should show up.

Independent website tracking the mission

It's now 3 hours since launch. Orion will separate from the upper stage in about half an hour, maneuver next to it to test procedures used for docking, then do a short burn to get away from it.

In terms of orbital mechanics, nothing big happens for almost a day now. There is a very short perigee raise burn in 10 hours.

This is NASA's idea of giving us a live view of the capsule. Generally, I'm not a fan of their camera selection during the mission so far:

Tx. I delayed going to my darts tourney until Artemis was safely in space.
