Subject: Artemis II PreTLE

I am supporting Artemis 2 PreTLEs on my site here: https://dillonsspacepage.com/pretle

The NASA official times/altitudes are not as precise as I would hope for plotting TLEs to this mission so there is still uncertainty with these elements.

The elements will dynamically change Epoch/RAAN/Inclination/ArgP based on launch window slips so make sure to monitor the site for those updates in close to real-time.

HOWEVER, I will provide rough elements here for the April 1st window in 20-minute increments through the window.
