HD Mars

High-Res texture and height maps for Mars

User reviews

Pretty good!

The game is amazing it’s just minor issues that bring it down to 4 stars number 1, the game crashes quite a lot but that just might be my device, number 2, the only explorable galaxy is the Milky Way which makes sense but they could add 4 different galaxies and only one has its things loaded while the others are empty and either add the planets or stars from the actual place or make up some planets and stars. Finally number 3, make a mode where it’s like no man’s sky but you can choose a planet to go on and you can fully explore it (like no man’s sky) but you can only go on that one planet.

I know the last one might be hard and expensive to make but I would enjoy if these could be added to your really good game!

Update ideas

It’s great, but I have a great update. You can make it more realistic where like when it crashes the particles that were on it, the other planet that crashed into this bigger planet the bigger planet can gain those stuff that was on and you should make it so the crash is like a while and it’s still going. You should make the oceans disappear all the greenery disappear and everything disappear but then like a lot of years later they can come back you should make a atmosphere disappearing effect and make a sort of when they crashed. They get rid of their atmosphere with the cool effect and make a salad stuff from the asteroid belt can go to earth and start colliding with different planet.

Good app but

Can you add a setting in the settings where you can turn off shadows

I like this game

It’s soo fun I play it everytime I’m bored can you add more textures like Theia or cube earth I really love this game! Edit: can you add more gas giant textures that also have a spot im working on v3 also can you add a Needoh planet that has a squish button instead of crack and has a code pls. Add a button that says make creature where you can put its color what it does creature type: dog cat seal human and also add a size button for the creatures and a spawn creature button

FAQ

What can I do in this solar system simulator?

You can explore existing celestial bodies in our solar system, including planets and moons, and even visit nearby stars. The app also allows you to create your own solar systems by adding or modifying celestial bodies.

How does the simulation work?

The simulation acts as a gravity and physics sandbox. It recalculates the orbits of celestial bodies based on Newton's laws of motion and gravity, providing a realistic physics-based experience.

Is this app free to use?

The app is free to download and use, but it does contain in-app purchases and advertisements. These may offer additional features or enhance the user experience.

What kind of celestial bodies can I simulate?

You can explore and simulate planets and moons within our solar system, as well as visit nearby stars and observe their positions in the Milky Way. You can also add new bodies or modify existing ones to create unique solar systems.
