Last year, astronaut Matthias Maurer completed a 177-day stint aboard the International Space Station (ISS). <i>“We know that without satellites, we wouldn't know anything about climate change. But also doing space research on the International Space Station can contribute a lot. For example, I had a key experiment which was mixing concrete in space. You’re wondering, why am I mixing concrete in space? We're not going to use concrete for space stations! But worldwide we produce more CO2 due to concrete for the buildings all around us than the entire aerospace industry. All the planes that fly around our planet Earth create not even the half of what the concrete creates on CO2. So just by doing research in space and improving an old material, we can also produce significant benefit to stop climate change.” </i> Matthias Maurer also mentioned that space has a big role to play in tackling the global crises we face. Space is even becoming more sustainable. It’s not just satellites and space junk that are jostling for space in orbit. The commercialization of space poses challenges, Matthias Maurer says.
