Over the last century, everything scientists have learned about Mars suggests that the planet was once quite capable of hosting ecosystems. It might still be an incubator for microbial life today. Mars is the fourth rock planet from the sun, just after Earth. It is just a smidge more than half of Earth’s size, with gravity only 38 per cent that of Earth’s. It takes longer than Earth to complete a full orbit around the sun, but it rotates around its axis at roughly the same speed. That’s why one year on Mars lasts for 687 Earth days, while a day on Mars is just 40 minutes longer than on Earth. Despite its smaller size, the planet’s land area is also roughly equivalent to the surface area of Earth’s continents.

Although water does exist on Mars, it’s locked into the planet’s icy polar caps and buried, perhaps in abundance, beneath the Martian surface. Scientists assume there could be a form of life on Mars. Mars is the Earth's neighbour in the Solar system. The year on Mars lasts nearly twice as long as the year on the Earth. The day on Mars is shorter than the day on the Earth.
