The Nili Fossae region on the northwest rim of Isidis impact basin, Mars, on Feb. 5, 2016. NASA/JPL/University of Arizona by [Marisa Gertz](https://time.com/author/marisa-gertz/) ## Marisa Gertz Apr 22, 2016 1:02 PM UTC The Mars Reconnaissance Orbiter has recently released this color image of the Nili Fossae region, one of the most colorful regions of Mars. Many regions of Mars are covered in a homogenous layer of dust or regolith, but here, the combination of exposed bedrock, sand dunes, and diverse rock composition allows the colors to come through brilliantly. The camera operates in visible wavelengths, the same as human eyes, but can also capture near-infrared wavelengths to obtain information on the mineral groups present. The [HiRISE](http://www.uahirise.org/) (High Resolution Imaging Science Experiment) camera aboard the spacecraft is capable of returning images of the Martian surface with such a high resolution, that objects as small as one meter in length can be distinguished. Its stereo and color capabilities allow scientists to explore Mars in 3D and with compositional information, making it an important tool in investigating the safety of future landing sites for other missions, such as the Phoenix lander, MSL (Curiosity), or the Mars Science Laboratory. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4303093/nili-fossae-the-most-colorful-region-on-mars/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4303093/nili-fossae-the-most-colorful-region-on-mars/"},"headline":"Nili Fossae: The Most Colorful Region on Mars","datePublished":"2016-04-22T13:02:26.000Z","dateModified":"2026-02-22T16:55:49.960Z","description":"From the HiRISE camera","url":"https://time.com/4303093/nili-fossae-the-most-colorful-region-on-mars/","keywords":["Space","Mars","Science topic","one-pic"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt24a670167fd83eb5/69889024cf40a8af7ec42eba/nili-fossae-mars-hirise-color.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Marisa Gertz","jobTitle":null,"url":"https://time.com/author/marisa-gertz/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt24a670167fd83eb5/69889024cf40a8af7ec42eba/nili-fossae-mars-hirise-color.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"nili-fossae-mars-hirise-color","caption":"The Nili Fossae region on the northwest rim of Isidis impact basin, Mars, on Feb. 5, 2016.","creditText":"NASA/JPL/University of Arizona","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4303093/nili-fossae-the-most-colorful-region-on-mars/","name":"Nili Fossae: The Most Colorful Region on Mars"}}]}] ```
