Episode Summary:

This week we're talking about space launch. 2026 marks the 100th anniversary of liquid-fueled rockets, when Dr. Robert Goddard successfully pioneered the first launch from his aunt's farm in Auburn, MA. Like the Wright Brothers before him, Goddard’s breakthrough opened the door to a new domain and the exploration, operations, and economic development that have evolved ever since. Mitchell Institute experts and John Reed, the Chief Rocket Scientist at United Launch Alliance, discuss this milestone event, launch advancements over the past 100 years, the future of this technology, and why it all matters.

Note regarding ISP:

Isp or “Specific Impulse”, as we talked about, is a measure of a rocket efficiency. It is calculated as the Thrust force divided by the product of the mass flowrate of propellants times the gravitational acceleration in a 1 g field - (F/(mdot * g0). If we think about force in Newtons second law, with F=ma, we can see that we have mass divided by flowrate (or mass/sec) and acceleration divided by acceleration. These units resolve to what we term seconds of impulse. As we discussed, the acceleration of the fuel is a function of the exhaust velocity of the combustion products. This efficiency is driven by the combustion chamber design and chemical process as well as the nozzle design. These elements were all developed for rockets by Robert Goddard in his laboratory and field demonstrations.

Episode Summary:

In this episode, our team discusses Operation Epic Fury from an air and space set of perspectives. We also explore top defense issues in Washington, D.C., with a special focus on the FY27 defense budget. Plus, we explain the latest in spacepower—everything from missile warning & tracking developments to the Geosynchronous Space Situational Awareness Program (GSSAP).

Episode Summary:

For decades, adversaries like China have pressed hard to erase the spacepower advantage of the United States. This includes weapons to attack our space systems and technologies on orbit to hold U.S. forces in all domains at risk. Bottom line, space is more contested today than ever before. Our Mitchell Institute team explores these realities with Chief Master Sergeant Ron Lerch, the Space Force Senior Enlisted Advisor to the Deputy of Chief of Space Operations for Intelligence. This is a crucial conversation you won't want to miss.
