INDI is an instrument-neutral distributed interface control protocol that aims to provide backend driver support and automation for a wide range of astronomical devices (telescopes, focusers, CCDs, etc.). Current supported devices include many telescopes, CCDs, filter wheels, focusers, and video cams. INDI is used in popular astronomy suites like Xephem, KStars, DCD, and Cartes Du Ciel.
MarsClock is designed to aid engineers, astronomers, Gods of War, Hrossa, and specifically mission controllers for the upcoming NASA MER and ESA Beagle-II missions to Mars. It converts to and from Earth time (Local and UTC) and Mars time (Local Mean Solar Time and Local True Solar Time) for any location.
KAstrometry is an astrometry program for KDE. It is written in Python. It aims to be a good tool to make measurements of objects in space from images taken by CCD cameras. Such measurements might be used to find orbits of astroids or record the brightness of variable stars. One day, it should be able to record an object's position, detect stars, and find coordinates using star catalogs.
Sunwait is a small program for calculating sunrise, sunset, civil twilight, nautical twilight, and astronomical twilight. It has options to wait until some time-offset from one of these events, making it useful for home automation tasks that should happen relative to the sun's position.
Mars MOLA Viewer displays a fly-over rendering of the Martian surface, as measured by the Mars Global Surveyor, in real-time 3D animation. It downloads the Mars Orbiting Laser Altimeter topographic data files and uses them to drive the rendering. The user controls the position and the angle of the camera, and can move seamlessly over the entire Martian surface from -88 to 88 degrees latitude. It is a Java Web Start program with 1-click installation from your browser (depending on platform/browser).
skyviewer is an OpenGL-based program to display HEALPix-based skymaps, saved in FITS format files. The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card.
jAscom is a wrapper around the JACOB (JAva-COM Bridge) libraries for easy access to the ASCOM Platform 3.0 using Java. It provides all functionality (methods and properties) of the ASCOM Telescope API version 2. It also includes the Focuser and Dome API. This means easy and fast coding of Java applications for all sorts of telescope controlling problems, using a widely accepted standard.
McIDAS-Lite is a freely available demo for the full McIDAS software. It will connect to a variety of free online data sources for satellite data and display the images in a viewing window. Images can be looped and analyzed, and graphics overlays can be created to show maps and other geographical features. It is available for AIX, HP-UX, Irix, Linux, Mac OS X, Solaris Sparc, Solaris x86, and Windows XP with SFU.
