The HiRISE HiTranslate project uses volunteers from across the globe to translate captions describing the high-resolution images taken by the HiRISE Mars camera.

By translating the image captions into their native languages, volunteers make HiRISE discoveries accessible to non-English speaking space enthusiasts.

Due to the response, HiRISE now has three separate language sections: Spanish, Italian, and Greek.
