The 2003 Mars Viewer requires a browser with JavaScript that will enable you to see what features on Mars are visible for a selected date and time. Save this entire page to your computer's hard disk for offline use.

You can click on the individual calendar dates, calendar months, clock numerals, or the arrows to change the date and time. If you have one of the latest browser you can start from June 1 and advance through to the end of October to watch the planet's size change from day to day.

The displayed image of Mars appears as it would without optical aid with celestial south at bottom and celestial east at left. If you have a Newtonian telescope your image will be inverted (celestial south at top and celestial east at right); through a Schmidt-Cassegrain the image will be mirrored (celestial south at bottom and celestial east at right).




What Features Am I Looking At?



Print out a copy of the large black and white Mars Map from the Association of Lunar and Planetary Observers. Here is a smaller map.

The Mars Viewer has been tested with NN 4.7, NN 7.0, IE 6, Opera 7.11, Mac Safari/IE 5.2 and Mozilla 1.3. Your time offset from Greenwich is obtained from the JavaScript environment. However, Safari doesn't correct for Daylight Savings in the offset.

If you have any problem, since this is still a work in progress, e-mail Bob Davidson.

The surface features were rendered with POV-ray using Dan Troiani's 1997 Albedo Map.
