Vast amounts of data from Mars arrive on Earth.
Some of the imagery is stored online here: HiRise Image Catalog
To download and view the imagery, free software is provided. It supports the JPEG2000 format of the data. Click here: HiView Software
The software is able to zoom deeply into the Mars terrain. At high zoom levels and while slowly scrolling, a person can take a “virtual walk” on the surface.
Mars is littered with artifacts. Finding them is very easy.
