These are TLE estimates for the actual launch time of 2022-11-16T06:47:44. 
Orbital elements have been estimated from the timeline and parameters by Jonathan
McDowell (https://planet4589.org/space/misc/artemis1.txt).

The TLE describing translunar orbit is only valid for the first 2 days after launch,
as TLEs do not properly model the influence of the Moon at large distances from Earth.
