NASA is getting into gear to have lots of coverage of this mission:
https://www.nasa.gov/news-release/nasa-sets-coverage-for-first-artemis-crewed-mission-around-moon/
You can also register as a ‘virtual attendee’ and receive mission updates, resource material, etc to your e-mail Inbox:

(Link takes you to Eventbrite for a free ‘launch ticket’)
There’s also a link to track the Orion craft in space:
https://www.nasa.gov/missions/artemis-ii/arow/
although I guess this will be a graphic of the mission’s progress rather than astrometric-quality coordinates such as:
https://ssd.jpl.nasa.gov/horizons/
or Bill Gray’s Project Pluto:
https://www.projectpluto.com/
which will publish ephemerides after the spacecraft has left Earth orbit.
