Lux Aeterna: Reusable Satellites

The Future of Satellites: Reusability and Cost Reduction

Satellites perform a multitude of vital functions, ranging from providing internet access to aiding in wildfire monitoring. However, the lifecycle of many ultimately concludes with destruction as they burn up within Earth’s atmosphere.

Alternatively, some satellites are maneuvered, utilizing their remaining fuel, into designated “graveyard” orbits, remaining in a state of perpetual, frigid circulation around the planet.

Introducing Lux Aeterna and the Delphi Satellite

A new company, Lux Aeterna, is challenging this conventional fate for satellites. Emerging from stealth mode, the Denver-based startup has engineered a reusable satellite, named Delphi, with a planned launch and landing scheduled for 2027.

Successful implementation of this technology promises a significant reduction in the expenses associated with deploying satellite payloads into space.

Furthermore, it introduces a level of flexibility currently unavailable, as traditional satellites are designed for extended orbital durations and lack the capacity for in-orbit modifications.

Government and Investor Interest

These capabilities have already garnered attention from the Department of Defense, recognizing the importance of low-Earth orbit within the United States’ military strategy.

This interest has translated into financial backing, with the startup securing $4 million in pre-seed funding, spearheaded by Space Capital and including contributions from Dynamo Ventures and Mission One Capital.

The Inspiration Behind Lux Aeterna

Brian Taylor, Founder and CEO, attributes the genesis of Lux Aeterna to witnessing a SpaceX Starship test launch last year.

“My goal is to contribute something truly remarkable to Starship, something that fundamentally alters the entire industry,” Taylor stated in an interview with TechCrunch.

Leveraging Heavy-Lift Rockets

Starship, currently the largest rocket ever constructed, possesses the capacity to deliver larger payloads into space than previously achievable.

This increased capacity is crucial for satellite developers, who often design around the limitations of available rocket cargo space.

Blue Origin’s New Glenn represents another example of a heavy-lift rocket contributing to this expanded potential.

Surviving Atmospheric Re-entry

Designing a satellite capable of withstanding the extreme conditions of re-entering Earth’s atmosphere at high velocities presents a significant engineering challenge.

However, the additional space provided by these heavy-lift rockets enables the construction of a satellite that can endure multiple re-entries without compromising on technological advancements due to cost or weight constraints.

Heat Shield Technology

Lux Aeterna’s solution involves the implementation of a heat shield. The Delphi satellite’s conical heat shield, as depicted in the startup’s released rendering, bears a resemblance to those utilized in NASA’s renowned spacecraft.

This design choice is deliberate, according to Taylor, as these proven designs have demonstrated effectiveness.

“We thoroughly examined NASA’s past missions involving exploratory endeavors and sample return, which significantly informed our architectural decisions,” he explained. “It’s vital to build upon existing knowledge when undertaking ambitious projects like this.”

Delphi’s Operational Details

Taylor refrained from disclosing detailed specifics regarding the operational mechanics of the Delphi satellite or the refurbishment processes Lux Aeterna will employ between launches.

Team Expertise

The team behind Lux Aeterna possesses substantial experience in the satellite industry. Taylor previously contributed to the Starlink project at SpaceX, Amazon’s Kuiper satellite program, and the space infrastructure startup Loft Orbital.

Launch and Testing Plans

The initial launch of Delphi is planned for 2027, utilizing a SpaceX Falcon 9 rocket. The satellite will complete a full orbital flight before returning to Earth.

Lux Aeterna intends to repeat this process to validate Delphi’s reusability.

Subsequently, the team is developing a larger production vehicle designed for even greater reusability.

A Young Industry with Vast Potential

Despite the advancements in spaceflight technology, Taylor believes the industry remains in its nascent stages, presenting ample opportunities for companies like Lux Aeterna to establish a sustainable business.

“The industry hasn’t reached the maturity level of computer chips or the automotive sector,” he noted. Satellite reusability will be a key driver in accelerating this maturation.

Taylor expressed excitement about the unforeseen possibilities that will emerge within a space-based economy.

“We are only beginning to understand the potential that lies ahead,” he concluded. “That is, perhaps, the most thrilling aspect of all.”
