In-Orbit Manufacturing, AI Data Centers, and the New Space Economy with MIT’s Ariel Ekblaw
For most of human history, space has been a place we visited. The next chapter may be about building there.
For decades, space was the domain of governments, astronauts, and science fiction. Today, falling launch costs, reusable rockets, and a new generation of ambitious founders are turning orbit into something else entirely: a place to build. The question is no longer whether humanity can construct large-scale infrastructure in space, but what we should build first-and why.
In this episode of TechSurge, host Sriram Vishwanath speaks with Dr. Ariel Ekblaw, Founder and CEO of Aurelia Institute, Research Affiliate at MIT’s Space Exploration Initiative, and founder of Rendezvous Robotics. Ariel has spent her career exploring one of the most fundamental challenges of the emerging space economy: how to build structures in orbit that are far larger than anything that can fit inside a rocket.
Ariel explains the origins of TESSERAE, her pioneering work on autonomous self-assembling space architecture, and how ideas borrowed from biology, swarm intelligence, and modular construction could unlock a future of massive solar arrays, communications infrastructure, orbital laboratories, and eventually human habitats in space.
The conversation explores the rapidly emerging market for in-orbit infrastructure, including AI data centers in space, space-based solar power, and the technologies needed to support a permanent industrial presence beyond Earth. Ariel breaks down the engineering realities behind these ideas—why cooling data centers in space is harder than most people assume, how autonomous assembly could solve the scale problem, and why the future of orbital infrastructure may look more like a business park than a collection of standalone satellites.
Sriram and Ariel also discuss the broader implications of humanity’s return to space: the economics unlocked by reusable launch systems, the opportunities created by dramatically lower transportation costs, and the second-order innovations that may emerge from building an industrial ecosystem in orbit. Along the way, they examine space debris, stewardship of the orbital commons, artificial gravity, and what it will take to make long-term human habitation in space viable.
At the heart of the discussion is Ariel’s belief that space is not an escape from Earth’s problems, but a tool for solving them. Whether through advanced manufacturing, new energy systems, biotechnology research, or entirely new industries, she argues that the next era of space exploration should be focused on improving life here at home.

MIT President Emeritus Dr. Rafael Reif joins host Michael Marks for a discussion about the state of U.S. competitiveness in technology, university research funding, current immigration policy, and more. Reif explains why universities remain the innovation engines of economies, educating top talent and generating the foundational research that powers emerging tech and creates new industries. He candidly assesses U.S.-China competition, warns that Chinese research output is rapidly outpacing our own, and urges renewed federal investment.
The discussion explores how restrictive immigration policies threaten the flow of global talent into the U.S and his own impression of current policies as an immigrant from Venezuela himself. As a TSMC board member, Reif also touches on the strategic need for domestic semiconductor fabs, Intel’s path forward, and TSMC’s edge in advancing cutting-edge nodes. Lastly, he addresses gaps in the venture capital funding space and why he created MIT’s The Engine incubator model to fund “tough tech” startups, which helped launch breakthroughs like Commonwealth Fusion Systems.

Many in venture capital and biopharma are anointing artificial intelligence the savior of drug discovery—but what can AI actually do?
In this eye-opening episode, Michael Marks sits down with Mike Nohaile, CEO of Prellis Biologics, to explore the hype versus reality in AI-enabled drug discovery. Mike details why, despite significant breakthroughs like AlphaFold and recent Nobel Prize win for computational protein design, fully AI-generated medicines still present challenges. He also discusses why we urgently need more effective medicines and details Prellis’ unique system which combines laser printed human organoids and an externalized human immune system with AI, enabling the discovery of fully human antibodies.

With global economic alliances shifting and new threats emerging, will the U.S. maintain its dominance in an increasingly complex world?
From cryptocurrency to chips to cyberterrorist threats, the battle for global dominance is no longer just fought on the battlefield—it’s playing out in markets, boardrooms, and cyberspace. In this episode, we sit down with Juan Zarate, a key member of the post-9/11 Bush Administration team fighting terrorist financing and financial crimes, and an architect of how we view modern financial warfare.
We explore how the U.S. has used its economic dominance as a powerful weapon—and whether countries like China and Russia are now using the same playbook to push back. Juan shares insights on the weaponization of the dollar, how financial crime networks are evolving in the digital age, and why strategies around cryptocurrency could either threaten or reinforce U.S. economic power.
The conversation dives into the intersection of technology, economic, and national security strategy, tackling key issues like cyber threats, semiconductor supply chains, and the growing role of AI in financial security. Juan also introduces his latest venture, Consilient, which is pioneering federated AI to revolutionize the fight against financial crime.
