For more than two decades, Elon Musk has focused SpaceX, his rocket company, on his lifelong goal of reaching Mars.
Over the last year, he has also ramped up work on what will happen if he gets there.
One team is drawing up plans for small dome habitats, including the materials that could be used to build them.

The initiatives, which are in their infancy, are a shift toward more concrete planning for life on Mars as Mr. Musk’s timeline has hastened.
