Can astronauts spend prolonged time in close quarters millions of miles from Earth without killing each other?
While NASA rovers on the surface of Mars look for hints of life, researchers back on Earth are studying ‘echoes of life’ from ancient basins – hoping that the two sites might be similar.
Mars has been a popular destination since space exploration began – and there are plenty of people who’d love to go there.
Among the missions being planned is a huge helicopter drone to explore Saturn’s moon Titan.
In sci-fi depictions, extraterrestrial habitats have evolved tandem with scientific understanding of conditions on planets
You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
Moons and asteroids will be visited by spacecraft from Earth next year.
A Japanese spacecraft is expected to reach Martian orbit in 2025 to collect material from the surface of the moon Phobos before returning to Earth by 2029.
Some space rocks you can get for free – if you know how to identify them. Rarer materials cost more, and the asteroid sample NASA just brought back has a high price tag.
Control experiments are critical in informing the search for alien life.
Space can damage everything from your cardiovascular and nervous systems to your mental health – long voyages can feel isolating for many.
Planetary analogues are sites on Earth that are so extreme that they replicate those of celestial bodies in our solar system.
If an astronaut were to die on Mars, neither cremation nor burial would be good options.
There’s a limit to the amount of oxygen we can carry with us in space – particularly if we want to do long-haul journeys to the Moon and Mars.
If we could go sightseeing across our cosmic neighbourhood, these would be some of the best highlights.
The launch of a new rocket is always an exciting event. SpaceX’s ‘go fast and fail’ approach means that even though the test ended with engineers blowing up the rocket, it was a valuable first flight.
Jupiter’s moon Io has more than 400 active volcanoes on its surface.
It all starts with a cloud of gas and dust.
Our Mars rovers might not be sensitive enough to detect signs of life. But lessons from Antarctica might make future missions more successful.
Agricultural technologies to grow food on Mars can help address climate change, sustainability and food scarcity challenges.
