You wouldn't want to sunbathe on Mars, but, according to analysis of soil in Gale Crater by the Curiosity rover, the soil there is similar to that found on the flanks of Hawaii's Mauna Kea volcano. Actually, you may not want to sunbathe there, either.
Curiosity's work so far also shows more evidence of interaction with liquid water in early soil, and an extremely dry environment later on, which is consistent with the overall picture of Mars' history that scientists are piecing together.
