Mars Terrain Explorer is the free in-browser way to see real MOLA elevation data on a spinning globe - without installing NASA Mars Trek or desktop GIS software.
| Option | Real elevation data | Install | Best for |
|---|---|---|---|
| Mars Terrain Explorer | Yes - real NASA MOLA dataset | None (browser) | Fast elevation literacy |
| Earth 3D Globe | Procedural day/night texture, not elevation | None | Geography / lighting |
| NASA Mars Trek | Full mission-grade Mars GIS | Web app (heavier) | Deep geospatial analysis |
| Desktop GIS (QGIS) | Full control, any dataset | Install | Professional mapping |
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
