There are loads of applications for 3D printers in space.
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.
The Astronomer Royal answers some of the world’s – and the universe’s – biggest questions.
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it’s time to figure out what happens to our biology in its absence.
A twin experiment in space can help us prevent diseases on Earth.
Scientists have finally found an Earth-like planet we may actually be able to visit.
Scientists are working out how to grow plants in space, ready to use them as food when we visit other planets.
In theory, astronauts get the equivalent of a lethal x-ray dose during a six-month stay at the ISS. Here’s why we don’t have to worry too much though.
Former NASA astronaut Ron Garan speaks his mind about space travel, terraforming and religion.
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
Inflatable space habitats, like the one installed on the International Space Station this week, could see wide application in space and planetary exploration.
The European Space Agency is exploring what we can learn from animals about long-term deep sleep.
Scott Kelly’s year in space is over. Now we need to know what it did to his body.
