By Gareth Willmer A lunar rover that can analyse samples in situ and a Europe-wide facility to store extraterrestrial samples will help to protect moon samples from contamination and increase their usability in scientific experiments. In 1969, the Apollo 12 mission retrieved a camera that had been left on the moon by an earlier spacecraft. … Read more

Earth’s magnetic poles could start to flip. What happens then?

The magnetic field protecting our planet originates deep in the Earth's core but fluctuates in strength over time.

by Jonathan O’Callaghan As Earth’s magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard every human on Earth. This is a possibility that we may start to face not in … Read more

System to rid space station of astronaut exhalations inspires Earth-based CO2 removal

When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere? In order to limit global warming to 1.5˚C above pre-industrial levels and avoid some of the worse impacts of climate change, it … Read more
