The 2020s could define the future of space power. Dr. Bhavya Lal joins to make the case that nuclear’s game-changing role is not propulsion but power. Without it, humans cannot stay, build, or thrive beyond Earth. So with today’s launch giants, do we still need nuclear or can we.

Sometimes smaller space rocks hit Earth without warning—striking objects, people, or exploding in the sky. What’s it like when that happens? Here are some of the most well-documented encounters Earthlings have had with asteroids and meteorites.
