Nasa has discovered that if a human colony was to live on Mars, the chances of it being swiftly wiped out would be very high.
The Mars Reconnaissance Orbiter found that there are many more impact craters on the planet's surface than first thought, the International Business Times reported.
Mars is frequently hit by space debris due to its thin atmosphere, which cannot easily break up the material. When material arrives that can be broken up by the atmosphere, it often only splinters into smaller pieces, hitting the surface over a wider area.
Scientists working on human habitats for the planet have been concerned by the news, as it could mean the atmospheric integrity of any structure could be threatened, and endanger the lives of anyone living there.
Many of the craters are situated in an area of the planet called Tharsis, which is near to a volcanic plateau in the western hemisphere. The region has the largest volcanoes in our solar system.
The orbiter has been analysing the impact craters on Mars to give scientists more information about how meteorite impacts affect the surface of the planet.
Mineral content from the craters will also be analysed, in order to learn more about Mars' atmosphere, surface winds and the movement of particles.
