This will probably fall on deaf ears for those folks who don't have a VR headset, as they have no way of knowing how neutered the 2D monitor experience is compared to VR, unless they try it and specifically on planets in Elite.
It has been very possible to get a Neil Armstrong moment since Horizons landed for VR players and anyone who has the opportunity should try it and this is how to and what it is like:
First of all location, location, location; whilst anywhere will do, I find landing your ship on a high metal content world with decent canyons and cliffs provides the best views. Also see if you can find that location near the terminator (night/day transition zone) and even better if the body is in orbit around a gas giant, get it so both the main star and gas giant are in the sky together (in fact get as many other celestial bodies in your view as possible).
Land your ship and deploy the SRV and drive it as close to the edge of the cliff as possible.
Next you have to prep for EVA, as Neil and Buzz (and the other 10) would have had to. To do this stand up in your chair/cockpit and hit the recenter HMD key, which will have the effect of lowering your view point relative to the SRV, which is where the camera is normally anchored to. If you don't do this you can kind of fool yourself you are stood on the front wheel of the SRV, but its not as good.
Step out of the SRV in real life and if you have re-centered properly you will clip through the SRV and out onto the surface.
This is the Armstrong moment, as for all intents and purposes you are stood up and outside on an alien world with a canyon vista stretching out to the horizon. If you've picked your spot well then there should be a blazing star rising over that horizon and possibly a majestic gas giant in all its marbled glory hanging there in the sky. The wearing of a VR HMD helps as it feels a bit like wearing a helmet anyway, enhancing the feeling.
More than the view, you can feel the ground under your feet and to take in all the view, you can turn 360, as you would in real life (with care due to cables/said cockpit etc.). Your chosen landscape is all there to view and for an added bonus and provided you have room, step carefully to the edge of the cliff/canyon and feel vertigo as you lean over the edge and look on the misty depths thousands of feet/metres below you.
This is one area where the PiMax headsets really shine, as the 170 deg field of view horizontally (which is most of it) and almost all of your vertical field of view is the environment you see and having the view on planets all around and visible by using the attributes you are born with is hugely immersive i.e. your legs, your eyes and your neck/head vs. pressing buttons, joystick hats etc.
Using a monitor in comparison is about as awe inspiring in as looking at a spreadsheet, as you're sat down, looking at a restricted field of view, flat moving picture and apart from your eyes within that restricted field of view, you have none of the sensory inputs that help convince your brain you're actually there, thousands of light years from earth, looking over a view nobody has ever seen before.
Another analogy for VR vs. 2D on planet surfaces (and even seated in your cockpit and SRV) is the difference between going to the Grand Canyon vs. watching it on TV/Youtube. You can up the resolution of your TV as much as you like, but it will not be the same as being there in person - VR gives you more of that "being there".
