Longtime space rivals Elon Musk and Jeff Bezos are vying to reach outer space with their giant rockets. Meanwhile, an ecosystem of other space-related startups are racing to be ready to set up shop on the moon and Mars. Lunar Outpost is one of three companies competing to build a space truck for NASA's Artemis missions. Founder and CEO Justin Cyrus is betting there will be a commercial rush to tap into the moon’s resources, including critical minerals. He says he wants his company to be the “mobility provider” for the lunar economy. On the latest episode of Bold Names, Cyrus joins WSJ’s Christopher Mims to discuss why the U.S. and its biggest rivals are in a race to build permanent bases on the moon.
