Building Golden Dome, with Lt Gen (Ret) Nahom & Mike Dickey (Elara Nova)
Lt. Gen. (Ret.) David “Abu” Nahom spent decades defending the American homeland, from commanding Alaska Command and the 11th Air Force to shaping Air Force budgets and strategy as the A8. Mike Dickey started his career in the original Strategic Defense Initiative, helped build the USSF and now advises companies and government leaders on the future of national security. Together, they unpack the realities behind Golden Dome: what it is, what it isn’t, and why it may be the most complex defense undertaking of our time.Inside the episode:Why homeland defense is no longer a Cold War problem and why threats across all domains demand a fundamentally new architectureWhat it actually takes to detect, track, and intercept advanced weapons, from ballistic missiles to hypersonics to low-observable cruise missilesHow command & control is the real bottleneck, and why BMC2 will define the success or failure of Golden DomeWhy integrating F-35s, space sensors, legacy radars, and new AI systems is a social-engineering challenge as much as a technical oneThe role of startups in a mission where “move fast and break things” collides with the reality of life-or-death stakesWhy public perception lags far behind the actual threat picture and what Americans get wrong about homeland defenseThe technologies on the horizon that could completely reshape missile defense in the next decade• Chapters •00:00 – Intro00:41 – David's and Mike's Backgrounds04:01 – How Elara Nova has grown since last episode05:17 – What makes Golden Dome different?08:00 – How exposed has the US been to missile threats?10:53 – What is the Golden Dome supposed to look like today?14:02 – Not reinventing the wheel16:38 – Capabilities of today and tomorrow23:00 – How new modes of launch change missile defense24:57 – Integrating new solutions with current systems27:15 – Golden Dome isn't a technology problem29:41 – How much does ego play into the social engineering challenge of the Golden Dome?32:47 – Unable to fail in this startup-driven golden age of space and defense tech36:11 – Risks of the Golden Dome budget ballooning39:29 – The deterrence calculus42:12 – How will Golden Dome interface with our allies44:20 – Exciting defense tech being developed or doesn’t exist yet46:29 – How putting weapons in space changes things48:13 – Golden Dome issues they wish were fixed today50:24 – What everyday Americans don't understand about the Golden Dome53:01 – Measurable outcomes that the Golden Dome works54:56 – What Mike and David do for fun• Show notes •Elara Nova’s website — https://elaranova.com/Mo's socials — https://twitter.com/itsmoislamPayload’s socials — https://twitter.com/payloadspace / https://www.linkedin.com/company/payloadspaceIgnition’s socials — https://twitter.com/ignitionnuclear / https://www.linkedin.com/company/ignition-nuclear/Tectonic’s socials — https://twitter.com/tectonicdefense / https://www.linkedin.com/company/tectonicdefense/Valley of Depth archive — Listen: https://pod.payloadspace.com/ • About us •Valley of Depth is a podcast about the technologies that matter — and the people building them.

Power, Meet Shield, with Trevor Smith (CEO of Atomic-6)
Space has a power problem. Satellites need more electricity and better protection, yet solar arrays are slow to build and failure-prone, and shielding adds mass and complexity. Atomic-6 is tackling both sides at once.Our guest this week is Trevor Smith, founder and CEO of Atomic-6. His team is building Light Wing, a redeployable, mass-manufacturable solar array aimed at higher watts per kilogram and faster delivery, and Space Armor, an RF-permeable debris shield designed to stop hypervelocity impacts while preserving comms and resisting directed energy. The company’s first on-orbit hardware is slated for February 2026, and they’re pursuing multi-billion-dollar constellation opportunities alongside a long-term purchase agreement with a private space-station builder.Inside the episode:Why reliability, not just power density, wins satellite programsHow a space power gigafactory could reset constellation economicsWhat “cell-agnostic” really means for supply chain and performanceThe new “radome for space” capability and where it matters for defenseCislunar prospects, lunar-orbit data centers, and vertical solar towersLessons from working with Space Force and navigating dual-use fundingThe state of the U.S. industrial base and why solar arrays are a top supply-chain priority • Chapters •00:00 – Intro00:47 – How Atomic-6 got started03:06 – Building the power grid for space04:09 – Why is Atomic-6 building what it's building05:58 – Dollars per watt per kilo07:18 – Cell agnostic07:58 – How Trevor got into the space industry09:14 – Team construction at Atomic-609:49 – What type of people is Atomic-6 looking for?10:35 – Atomic-6's key product offering10:58 – Current customers and opportunities at Atomic-611:38 – Pipeline13:07 – Manufacturing scaling14:04 – How much is an operator spending on solar arrays?15:12 – Who would we go to today for building a satellite array and what would they be missing?16:33 – Space Armor19:44 – What is a radome?20:34 – Whipple Shield deployment21:11 – Significance of being transparent to radio signals21:41 – Terrestrial applications for the Whipple Shield23:24 – How Atomic-6 came to developing the Whipple Shield24:48 – Opportunity vs Light Wing and Space Armor25:38 – Defense traction with Space Armor26:52 – Atomic-6's business model29:17 – Milestones30:35 – Vertical integration32:34 – Other products that Atomic-6 is developing33:42 – Developments in advanced materials that will define architecture in space36:18 – What does success look like for Atomic-6 in 5 to 10 years?36:59 – What keeps Trevor up at night?38:05 – Government support40:17 – The legacy Trevor wants Atomic-6 to leave behind • Show notes •Atomic-6’s website — https://www.atomic-6.com/Mo's socials — https://twitter.com/itsmoislamPayload’s socials — https://twitter.com/payloadspace / https://www.linkedin.com/company/payloadspaceIgnition’s socials — https://twitter.com/ignitionnuclear / https://www.linkedin.com/company/ignition-nuclear/Tectonic’s socials — https://twitter.com/tectonicdefense / https://www.linkedin.com/company/tectonicdefense/Valley of Depth archive — Listen: https://pod.payloadspace.com/ • About us •Valley of Depth is a podcast about the technologies that matter — and the people building them.

The Case for Continuity, with Pam Melroy (Former Deputy Administrator of NASA)
Continuous human presence in orbit has been a cornerstone of U.S. leadership in space for 25 years. But recent changes to NASA’s Commercial LEO Destinations (CLD) strategy have Pam Melroy—former NASA Deputy Administrator and shuttle commander—sounding the alarm. She warns that shifting to short-duration missions risks ceding leadership in LEO and undermining U.S. readiness for Mars, opening the door for China to take the mantle.On this episode of Valley of Depth, we’re joined by Pam to talk about the state of NASA, the future of space stations, and why requirements, the often overlooked backbone of program management, will determine whether the U.S. stays ahead. We trace her career from test pilot to shuttle commander to senior leadership at NASA, DARPA, and the FAA, and unpack what it means to build an architecture that actually holds together from LEO to Mars.We also discuss:Why continuous presence in LEO is a national security and leadership issueHow the CLD Phase 2 shift could reshape investor and partner confidenceThe role of SpaceX and Starship in the Moon–Mars roadmapWhat it takes to write requirements that don’t doom a program from the startPam’s vision of LEO, the Moon, and Mars in 2045…and much more.This episode is brought to you by World Space Business Week, taking place September 15–19 in Paris.
