Description
Java-based application which displays a Mars "sunclock", a graphical representation of Mars showing the current sun and nightsides of Mars, along with a numerical readout of the time in a 24-hour format.
Other displays include a diagram showing the position of Sun and Earth for a given location on Mars and a plot showing the relative orbital positions of Mars and Earth.
Following the long-standing practice originally adopted in 1976 by the Viking Lander missions, the daily variation of Mars solar time is reckoned in terms of a "24-hour" clock, representing a 24-part division of the planet's solar day, along with the traditional sexagesimal subdivisions of 60 minutes and 60 seconds.
A Mars solar day has a mean period of 24 hours 39 minutes 35.244 seconds, and is customarily referred to as a "sol" in order to distinguish this from the roughly 3% shorter solar day on Earth. The Mars sidereal day, as measured with respect to the fixed stars, is 24h 37m 22.663s, as compared with 23h 56m 04.0905s for Earth.
