Twenty-one-year-old Mick has joined the Haas F1 team for 2021, following an announcement of his recruitment in December last year.
Part of the Ferrari Driver Academy, he won last year's Formula 2 title, just two years after coming out on top as the Formula 3 champion.
Now he's making the move into Formula 1, three decades after his dad did the same.
Ahead of pre-season testing he said: "As a child, I've been dreaming about this for 15 years - and now it's actually happened.
"It's emotional and just something very nice. My father actually had his first race in F1 30 years ago this year - that makes it even more emotional and even nicer.
"Coming from F2 we have very little experience on the F1 tyre. But we do have a good amount of experience with Pirelli tyres, so that's really going to be one of our focus points.
"We need to get even more information on how to prepare a single lap and also how to prepare the tyre for race distances.
"The races this year are very much longer than the ones we had in F2 and obviously now we only have one race each weekend.
"We have to be able to extract as much knowledge from the free practice sessions and qualifying to be able then to put everything into the performance for the race."
Sadly, his father won't be there on the day to watch Mick make his debut, as he continues to recover from a severe brain injury suffered in a 2013 skiing accident.
After being rushed to hospital for emergency treatment, he was placed into a medically-induced coma until June 2014, before later being moved home to continue treatment and rehabilitation privately.
Guenther Steiner, team principal of the Haas Formula One Team, has said he doesn't expect Mick to have 'great results' today, but that it's all about him learning.
Speaking to Autosport, he said: "This year Mick won't have any great results because he doesn't have the material for it.
"But the big result for Mick will be that he learns as much as he can and is ready when our car gets better, when his future starts.
"He's not just here for two years, which is usually in Formula 2 or Formula 3. He's here for a long career.
"The first year in Formula 1 is always difficult when you get there, to be there right away and to be competitive. The material plays a huge role here.
"Knowing what kind of material [we have] this year - I don't want to downplay it now - but we made a decision that we're not going to develop this year in order to fully focus on next year.
"That's why we can't expect Mick to be P1 or P2 after the first qualifying session."
