London, United Kingdom — 29 May 2026 — The playable demo of PlanetMars3D: Spirit Mission is now available on Steam.
PlanetMars3D: Spirit Mission is a Universe3D-powered 3D viewer for real NASA Spirit rover Pancam photographs. The demo lets players explore curated Mars rover albums in interactive 3D, glide between images, switch between manual exploration and automated flythroughs, and experience the Spirit mission as a spatial journey across the Martian surface.
The app is a dedicated viewer for selected Spirit rover Pancam imagery and does not create or edit personal photo projects. Album3D remains the related Universe3D app for personal 3D photo experiences.
Players can download the demo from the PlanetMars3D: Spirit Mission Demo page on Steam, wishlist or follow the PlanetMars3D: Spirit Mission store page on Steam, or learn more on the Universe3D website.
