The red planet. It may hold no life, but is it dead?
NASA has released a sound recording from Mars. So what do these literally otherworldly sounds tell us about the processes at play inside the red planet?
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.
Once people get there, Mars will be contaminated with Earth life.

NASA's InSight Mars lander touches down Nov. 26, part of a careful robotic approach to exploring the red planet. But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?
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.
InSight aims to figure out just how tectonically active Mars is, and how often meteorites impact it.
What is Mars made of? We hear from a scientist who will be part of the team analysing 'marsquake' seismic data and orbital imagery from the InSight mission to the red planet.
An artist’s rendition of the InSight lander - which will collect data on what’s inside the planet Mars.
The InSight Lander mission to Mars is preparing for launch in May 2018. But there are seven (or eight) other planets to explore: why have we such a hang up on Mars?
