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.
The first ever sound recording of a dust devil on Mars reminds us that there is a lot to learn about how they sculpt the landscape.
China has completed construction of the Tiangong space station, and science projects are now underway. The station is an important piece of China’s ambitious plans for space activity in coming years.
Spacecraft are just a small part of what it takes for humans to become an interplanetary species. A political science professor explains how there is much more to creating a spacefaring society.
A team of scientists have found a surprising amount of water ice on Mars.
A study has found that microorganisms living on Mars billions of years ago may have left the planet uninhabitable.
