It’s core to life on Earth.
The Earth's core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
Artist’s impression of InSight after its scientific instruments have been deployed.
From turning on instruments to gathering the first data, the next few months will be busy for Mars scientists.
Signs of life on Mars? These are the tracks of NASA’s Curiosity rover exploring the Martian landscape.
Mars has long captured our imagination, from claims of canals to Martian attacks and now our latest NASA exploration to look inside the red planet.
If you went to Mars, you’d need to be able to survive an extremely punishing environment. This picture, taken by NASA’s Mars Exploration Rover Opportunity, gives you an idea.

I've worked with NASA’s Mars Exploration Rover Project for 16 years. If you got yourself a ticket to Mars, here's how I'd advise you to prepare. And by the way, any mistake could kill you.
Once people get there, Mars will be contaminated with Earth life.

Earth experiences constant volcanic activity - here’s Indonesia’s Mount Anak Krakatau (Child of Krakatoa) photographed in July 2018.
Compared to Earth, more "oomph" is required to bring magma to the surface of Mars, and this is probably why we haven't seen any recent eruptions on the red planet.

The longest lunar eclipse this century, and other special features such as Mars looking spectacular will be seen.
We can create the right kind of food plants to survive on Mars.
If humans are to live on Mars they will need a stable supply of food. Earth plants are not suited to the Mars climate but we can engineer plants that are.
Mars’ south polar cap, as seen from Mars Global Surveyor. Buried beneath, we now know, is a lake of liquid water.
Researchers have found evidence of a large lake of salty water, buried 1.5 kilometres beneath the southern polar ice cap on Mars. So what does that mean for life on the red planet?
