<p>For Earth, there is lot of free satellite data easily available. For example, I can download the Sentinel-2 optical images freely from <a href="https://scihub.copernicus.eu/" rel="nofollow noreferrer">https://scihub.copernicus.eu/</a>.

If there is no remote analogue to Sentinel-2 in terms of data availability, why?</p>

# Mars satellite data similar to Sentinel-2?

(Asked by: username_0 on 2021-10-11)

For Earth, there is lot of free satellite data easily available. For example, I can download the Sentinel-2 optical images freely from <https://scihub.copernicus.eu/>. What would be the closest thing for Mars? I mean especially in terms of data availability. There are many satellites orbiting around Mars. If there is no remote analogue to Sentinel-2 in terms of data availability, why?
