Mars24 Win-8.2.2 火星模拟（NASA）

MARS24 INTRODUCTION Mars24 is a cross-platform Java application that 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 plot showing the relative orbital positions of Mars and Earth and a diagram tracing the path of the Sun during the day. Mars24 _requires_ that Java 9 (or later version) be installed on your computer. DOWNLOADING The current version of Mars24 may be found at: https://www.giss.nasa.gov/tools/mars24/ INSTALLING AND RUNNING THE WINDOWS PACKAGE The Mars24 package for Windows comes as zipped archive. It contains a directory, Mars24Win, which holds the following items: - Mars24.exe application. - "jars" folder containing several *.jar code files. - Martian landmarks file "marslandmarks.xml". - This README file. To run Mars24, double-click on the Mars24.exe application icon. If nothing happens when you double-click on Mars.exe, or if you see an error dialog with no message, then you may not have a complete Java Runtime Engine installed on your computer.
