Future Mars colonists may want to form their own legal system. What would stop them?
Beagle 2 shows the fine line between success and failure in Mars exploration. There's a lot we can learn from it going forward.
They erupted for billions of years and make Earth's volcanoes look like molehills. Here's what we know and what we don't know about them.
Musk’s audacious plan to blast people to Mars by 2024 glosses over some important social and political challenges that SpaceX will need to successfully navigate to get off the ground.
Sending humans to Mars is a 5-10 year project goal for several global operators right now. It's expensive - but Elon Musk unveiled his new commercial plan today.
Planetary protection protocols try to make sure we don't seed places like Mars with life from our planet. An astrobiologist argues they're misguided – especially with human astronauts on the horizon.
Will humans ever live on Mars? Whoever it is to get there first will benefit from the experiences of those who stayed in simulated Martian missions here on Earth.
Space exploration is exciting - but there are barriers for humans hoping to visit and even stay on planets. Buried ice on Mars could be a water source for interplanetary visits of the future.
Scientists used to believe that snowfall could never reach the ground.
The volcanoes would be a great place t to search for fossilised microbes.
We need a positive vision for humanity, not tech-driven life on Mars.
We will one day grow food in conditions as extreme as Mars. Developing the controlled environments required will help not only space explorers but also support our own survival here on Earth.
Musk dismisses one of the main technical challenges of being on the Martian surface: the temperature.
We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.
One of the best ways to find out the challenges of living on Mars is to simulate living on another planet here on Earth. So what's it like to spend several months living the Martian life?
To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.
From acoustic holograms to tractor beams.
JAXA has announced a mission to visit the two moons of Mars and return a rock sample to Earth.
Earth is a relatively dry planet compared to some of the other ocean worlds in our Solar system. Life needs water so what about life on these other places?
