European Space Agency astronaut Alexander Gerst works on an experiment aboard the International Space Station looking into how cement reacts in space.
Concrete could provide humans in space with better protection from radiation and extreme temperatures than many other materials.
In the future, when humans live in and visit space, they’re going to need places to stay and work. That calls for durable infrastructure such as concrete. For the first time, astronauts made cement in space as part of a project looking into the effects of microgravity, NASA said last week.
