Mars24 for Linux

Mars24 for Linux is a cross-platform Java application which displays a Mars "SunClock", a graphical representation of Mars showing the current day- and nightsides of Mars, along with numerical readouts of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of the four inner planets, a Panorama showing the solar path as seen from a given location on Mars, and the Mars analemma.
