Mars Photo of the Day - Oct 9 2011
Today's Image of Mars was taken by the Viking II Orbiter on June 7 1977. It shows wave clouds near the Martian south pole. These clouds result from wind passing over craters and picking up dust from the last global dust storm.
Unfortunately this image isn't as colorful or interesting as some, but it is important because it helps us to understand more about the Martian environment.
This photo of Mars links to the NASA's page for the photo.
Mars Photo of the Day - Sept 5 2011
Today's Mars Photo was taken by the European Science Agency (ESA)'s Mars Express. This photo of Mars is evidence that a massive lake once existed within Eberswalde Crater, which measures 65 km in diameter.
The delta is thought to have formed 3.7 billion years ago during the Hesperian Epoch, when an asteroid struck the Martian surface. Prior to this discovery it was thought that Mars was a barren, frozen planet, during the Hesperian Epoch, but the existence of this lake proves that there was liquid water present on the planet.

Mars Photo of the Day - Sept 3 2011
Today's Mars Photo was taken by Viking I shortly after landing on July 20 1976. It was the first photo ever taken from the Martian surface. When we compare this image to a more modern photo of Mars like this one, it is amazing how far our technology has come. Could you imagine getting photos from Mars Exploration Rover Opportunity that looked like this? How disappointing would that be?
The image here is as large as the original, so I have linked it to the NASA's informative page on the image.

Today's Mars photo is of Olympus Mons, the tallest known mountain and volcano in the solar system. At an estimated height of anywhere between 21-29 km, Olympus Mons is about three times as tall as Mount Everest. The whole mountain covers an area that is approximately the size of Arizona.

Today's Mars photo of this day is Odyssey Crater as taken by Mars Exploration Rover Opportunity. Odyssey crater is a small crater at the edge of the much larger Endeavour Crater. This has been Opportunity's goal for almost 3 years. For more information about this photo and why the location is so significant, just click on the photo itself!

The following series of images was taken from early spring of one Mars year to mid-summer of the following year. They show features on the slope of Newton Crater that might be evidence of salt water flowing on Mars today. The photos were taken during the warm season on Mars by the Mars Reconnaissance Orbiter.
