Ben Nowack

The 29-year-old former SpaceX engineer who built a fusion reactor in high school, went $50,000 into credit card debt to keep his vision alive, and raised $35M from Sequoia to launch the world's first commercial space mirror.

From Cape Cod to Orbit

Nowack grew up on Cape Cod, Massachusetts and showed an unusual appetite for ambitious engineering from an early age. By 14 he was building underwater robots. In high school he constructed a working Farnsworth fusor — a small-scale nuclear fusion device. During college he developed live-streaming cameras to monitor sea turtle habitats. These weren't school projects; they were personal obsessions.

After graduating from Wentworth Institute of Technology with a BS in Engineering, Nowack joined Park & Diamond, a startup making foldable bicycle helmets, before landing at SpaceX in 2020. There he worked on Crew Dragon's propulsion safety systems — the hardware that keeps astronauts alive if something goes wrong during ascent. He was 23.

The idea that became Reflect Orbital came from a science video explaining the inefficiency of solar energy distribution. Germany would need three times more solar panels than the Sahara Desert to generate equivalent energy from its own sunlight, and long-distance power transmission is expensive. Nowack started thinking about solving the problem from the other direction: instead of building more panels, redirect the sunlight to where the panels already are.

The Hard Years

Nowack left SpaceX and founded Reflect Orbital in October 2021, initially in Santa Monica. The early years were genuinely difficult. He went $50,000 into personal credit card debt keeping the vision alive before the company had any external funding. His core technical breakthrough was a parabolic-groove collimator — a precision structure inspired by the texture of a soda bottle that focuses scattered light into coherent beams, improving reflection efficiency by over 90%.

He also made an unconventional materials decision: using lightweight polyester film (Mylar) and modular design, he reduced system costs to what he claims is one-ninetieth of conventional models. The mirror on Earendil-1 — 18 × 18 metres — weighs just 16 kilograms. That's roughly the weight of a carry-on suitcase covering an area the size of a small house.

Tristan Semmelhack, a mechanical engineer from Zipline, dropped out of Stanford in December 2022 to join as co-founder and CTO. The pair moved Reflect Orbital to Hawthorne, California — the same city as SpaceX — to be close to the machinists and precision engineers who build rocket hardware.

Building at Scale

Heading into launch year, Nowack has been increasingly visible on the public stage. In October 2025 he spoke at the Up.Summit investor conference, framing the mission as "building reliable access to sunlight as a foundation for everything we want to achieve as a species." In January 2026 he appeared on The Generalist podcast in a full interview titled "Programming Sunlight" — his most detailed public explanation of the technology and commercial strategy to date.

Operationally, the company expanded its Hawthorne production facility by 25,000 square feet in November 2025 — a concrete signal that hardware production is scaling ahead of launch. The team, now approaching 70 people, includes engineers recruited directly from NASA's Jet Propulsion Laboratory who designed the origami-folding deployment mechanism for the mirror sail.

His public framing of the opportunity has sharpened over time. An early 2024 post summed up the thesis: "We think sunlight is the new oil and space is ready to support energy infrastructure." By 2026 the pitch has evolved to position orbital mirrors not as competing with batteries but as extending the solar generation window — a complementary technology for a world that needs more clean energy, not just shifted clean energy.

Why Tolkien?

Nowack named the satellite after Eärendil the Mariner from J.R.R. Tolkien's mythology — a half-elven mariner who sails the heavens carrying a silmaril (a brilliant jewel) as the evening star Venus, shining light down to those on Earth below. The parallel is deliberate: a satellite carrying a mirror, shining sunlight down to the world at night.

The name is also a signal about the ambition of the project. Eärendil in Tolkien's canon is not a minor character — he is the figure whose light gives hope to the peoples of Middle-earth in their darkest hour. Nowack has spoken publicly about seeing access to sunlight as an existential resource problem worth solving at civilisational scale.

What Critics Say — and How Nowack Responds

The scientific community's reaction to Reflect Orbital has been strong. The Royal Astronomical Society, American Astronomical Society, and DarkSky International have all filed formal opposition to the FCC application. The core objection: each mirror, when in the direct reflection path, will appear several times brighter than Venus. At 50,000 mirrors, the constellation would be brighter than every visible star combined.

Nowack's response has consistently been to invite scrutiny and offer to work with astronomers during the demonstration phase. Reflect Orbital has stated publicly that if astronomers hate the results of the Earendil-1 test, they can turn it off. The company has committed to coordinating with observatories during operations and has proposed exclusion zones around major telescope sites.

Critics find this insufficient — pointing out that the demonstration being reversible doesn't mean the commercial constellation will be, and that 260,000 service requests already filed suggests Reflect Orbital has no intention of stopping at one satellite.
