[0] It's a little messy because minifigs are quite squat and wide compared to their height.
Had to look that up[0], since I haven't closely been keeping up with LEGO since my childhood, and for now lack children of my own to renew interest. Interesting concept, but it doesn't look like they're still "officially" used?
EDIT: Oh, the article states that this set comes with two microfigs. My bad, I should pay closer attention next time!

Also that shuttle is absolutely not to scale. It's about 1:400.
As an AFOL that has done my fair share of MOCs, the thought of that (or at 1:40) hurts my wallet, I did a small Mars base MOC that fit on a single 32x32 baseplate and for the elements I was using to get the habitat shape I wanted I was ended up spending a little north of 95$. I wanted to make a vehicle and a rocket as well but I was looking at another 75-100$ each.
My pretty boring MOC Mars habitat and initial thoughts on how I'd go about attempting a permanent presence on Mars: https://www.ryanmercer.com/ryansthoughts/2016/7/29/my-lego-m...
If there's anything you ever want to see in lego, just google "MOC thing/theme" MOC being 'my own creation'. Chances are pretty good that an AFOL (adult fan of lego) has either built it with real elements or at least done it in LEGO Digital Designer or the (arguably) better Studio https://www.bricklink.com/v3/studio/download.page
Also PartDesigner is great for making custom elements and importing into Studio if you don't want to be a purist https://www.bricklink.com/v3/build/partdesigner.page
Then go download Studio and start tinkering digitally https://www.bricklink.com/v3/studio/download.page
When you got something you like, you can use studio to generate instructions and to buy the elements from sellers on Bricklink.
the minifigure dimensions are just completely off, so you can't expect a lot of realism here. i am happy if models are big enough that they are actually playable, and look like the real thing from the outside.
if there is one model where the scale issue is what's absolutely putting me off, it's the death-star. that thing is so far off its real dimensions that it just looks ridiculous to me.
