Mars is the fourth from the Sun and is commonly referred to as the Red Planet. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was named by the Greeks as Ares but the name that’s come down to us was given by the Romans in honour of their god of war. The ancient Egyptians named the planet Her Descher meaning the red one.

Currently there is more than one mission to Mars. Historically, the success rate of such missions to the red planet has not been good with about 50% failing. Interestingly, the USSR tried several times to get get probes there, but all failed.
The European Space Agency’s Mars Express and NASA’s Mars Odyssey and Mars Global Surveyor missions are all ongoing and, of course, the Spirit and Opportunity Mars rovers have had their on-planet missions extended. Sojourner was the first rover landed on Mars in 1997.

Mars is seen as the one planet that might provide a somewhat comfortable habitat for human colonisation (perhaps with a long program of terraforming). The “canali” seen by astronomer Percival Lowell in the late 1800s turned out, unfortunately, to be a trick of perception rather than great irrigation works constructed by the red planet’s imagined inhabitants. NASA are planning to send a manned mission to Mars but that could be decades away.

Meanwhile, amateur astronomers can gaze at the planet through today’s increasingly better performing telescopes and produce images that the professionals would have envied only a couple of decades ago.

On this page you’ll see where Mars is in relation to Earth and what face it currently presents to us. There’s also all the recent news on the red planet and missions to Mars. Towards the bottom of the page are various observation and data resources, including a couple of comprehensive online books.
