The Mars Global Surveyor spacecraft continues to orbit Mars and is sending back data from the red planet. As Mittlefehldt discusses in this Perspective, the interpretation of these data by Bandfield et al. (page 1626) sheds light on the martian global surface composition and suggests that Mars evolved very differently from Earth. Many puzzles remain that can only be answered with further remote sensing and in situ observations of martian rocks, especially laboratory study of returned martian rocks.
