Explanation

NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) probe was the first spacecraft to orbit Mercury. In 2012, it confirmed the presence of water ice and organic materials in permanently shadowed polar craters, and also detected water in Mercury's exosphere. Apollo and Columbia were human spaceflight programs, not Mercury probes.
