#178 | Heritage Meets New Space | Kristin Houston, Rocketdyne
My guest this week is Kristin Houston, CEO of Rocketdyne, the propulsion company behind engines like the RL10, and that has just become an independent company again after more than 60 years of heritage, most recently as part of Aerojet Rocketdyne and L3Harris. We talk about what it takes to combine that legacy with new space speed and culture, how the RL10 was modernized with additive manufacturing (cutting its part count by about 98%), the booming demand from national security, Golden Dome and in-space mobility, new propulsion paradigms, nuclear propulsion and power (and when we might see a reactor on the Moon), synergies within the AE Industrial portfolio, scaling production and the supply chain for a world of up to 100,000 satellites, the talent race, what the industry needs from government, risks like ASAT debris, and Rocketdyne's plan to roughly double its thruster output next year.
