Unfortunately, it wasn't equipped to analyse them in that location. However, the leading theory is that these were droplets of salty water.<ref name=phoenix_droplets_2009/> They were observed to grow, darken and coalesce<ref>Staff writers, "The Salty Tears Of Phoenix Show Liquid Water On Mars", Mars Daily, Ann Arbor MI (SPX) Mar 19, 2009</ref>, and then disappear, presumably as a result of falling off the legs.
