Mars' axial rotation period is very similar to the Earth's 24-hour period. Mars takes only slightly longer at 24 hours, 37 minutes and 22 seconds.

At the equator, Mars has a rotational speed of 868.22 kilometres an hour.

Because of the similarity in daylight between Earth and Mars, researchers operating equipment on Mars switch to a 'Mars day', to maximise the time they have to spend working during the Mars daytime.

Besides Earth, Mars is the most extensively-researched planet in the Solar System. As of July 2011, there were six active missions currently on Mars, or within its orbit.

Scientists have discovered the presence of ice on Mars, some of which is made from water, and the rest of which has so far been made from carbon dioxide. They've yet to find any evidence of liquid water.

The current Mars Rover mission is searching for signs that liquid water once existed, and that it might have once supported primitive life.
