Description

Guest: Dr. Bhavya Lal – Former NASA Chief Technologist, MIT-trained nuclear engineer, and architect of U.S. space nuclear policy.

The Cosmic Scoop:
Nuclear power’s bad Earthly reputation hides its potential as a lifeline beyond our planet. Space is already radioactive—and if we want to stay and build on the Moon, Mars, or Europa, nuclear offers “power abundance” solar can’t match. Dr. Lal explains why, covering tech, safety, law, history, and why the next space era may finally embrace it.

Quotable Insights:

  • “Solar lets you visit. Nuclear lets you stay and build.”
  • “Without nuclear, we design for scarcity. With nuclear, we design for capability.”
  • “Adding nuclear in space is like pouring water in a hurricane—it barely registers.”
  • “We are entering an era of abundance.”
