What this is built on

Novera is made by Royendgel Silberie, and the game itself is not open source. But almost nothing here was made from nothing: the planets are other people's survey data, and the engine it is built on is other people's open source. This page is who they are.

Planetary data

Every body's surface imagery and topography is public-domain NASA, USGS or ESA data, baked offline into the tiles that ship with the game. Hosted for the most part by the USGS Astrogeology Science Center planetary map service.

Mercury: NASA/JHUAPL/Carnegie MESSENGER MDIS color mosaic; MESSENGER global DEM v2
Venus: NASA/JPL Magellan C3-MDIR colourised radar mosaic
Moon: NASA SVS CGI Moon Kit (LRO LROC WAC + Clementine color); LRO LOLA topography
Mars: NASA/USGS Viking MDIM 2.1 colourised mosaic; MGS MOLA MEGDR topography
Phobos & Deimos: NASA Viking Orbiter mosaics; Mars Express HRSC shape model (Phobos). Deimos has no global DEM, so its shape comes from the published IAU tri-axial radii.
Jupiter & Saturn: NASA/JPL/SSI Cassini global cylindrical maps
Io, Europa, Ganymede, Callisto: NASA/JPL Voyager and Galileo SSI mosaics
Titan: NASA/JPL/SSI Cassini ISS controlled global mosaic
Uranus & Neptune: Voyager 2 and HST derived cylindrical basemaps

Models

Four engine models are by MartianDays on Sketchfab, used under Creative Commons Attribution 4.0. They have been modified for Novera: renamed to fit the game's own parts list, and adjusted in scale and materials to sit alongside the rest of the parts.

They remain under that license, which means anyone else may use them too, on the same terms — go to the original, linked below, rather than pulling them out of the game.

Software and type

Bevy: The Rust game engine Novera is built on. MIT / Apache-2.0.
Rust: And the very large tree of crates underneath, each under its own license.
Inter: By Rasmus Andersson, under the SIL Open Font License 1.1. The same typeface as the game, and the license ships with both. Read the license.
