From the link;
Jarrah White is an Australian filmmaker, astrophysicist and geologist. He has Certificate III & IV qualifications with distinctions in Screen and Media at the Sydney Institute of TAFE NSW, Australia; and a BSc with a Major in Geology and a Minor in Astrophysics completed in November 2017 and July 2019 respectively.
Is a person really an astrophysicist if they only have a minor in that field?
Did he really learn much of anything about film making if he doesn't understand why 1960's tech was not up to the task of faking the moon landings?
He reminds me of Dr. Peter Venkman, who treats science as some kind of dodge or scam.

EDT; The host (moderator?), Danielle Dallas Roosa is the granddaughter of Apollo 14's Stuart Roosa. I suspect White might use this to accuse her of favoritism if he is made to behave himself and does poorly at the debate.
