About

Lux Aeterna is a space infrastructure company developing reusable satellite and reentry platforms to make orbital operations more cost-efficient and repeatable. By separating the stable satellite bus from the payload, the company enables satellites to be launched, returned to Earth, refurbished, and redeployed, applying a reusability model to satellite infrastructure. This approach aims to transform space logistics from single-use missions into a sustainable, fleet-based operation.

The company's primary innovation is applying the reusability concept, popularized by SpaceX for launch vehicles, to the satellite platforms themselves. This is enabled by proprietary heat shield technology designed for multiple reentries and a vertically integrated system that allows for rapid payload swapping and refurbishment.

Reusable Satellite Bus Platform

Reusable Satellite Platform

Lux Aeterna's core offering is a vertically integrated, reusable satellite bus designed to host various payloads. The platform can be launched, operate on-orbit, re-enter the atmosphere, and be recovered for refurbishment and subsequent missions, significantly reducing the lifecycle cost of orbital operations. The design is based on Mars-derived heat shield technology and features modular payload bays for flexibility.

  • Proprietary heat shield technology engineered for up to 15 years of on-orbit capability or 15 reentry cycles.
  • Modular payload bays that separate customer hardware from the core satellite infrastructure, allowing for rapid integration and deployment.
  • Flexible business models enabling customers to lease orbital access for periods ranging from six months to five years.

Built for

The company targets three main sectors: defense and intelligence agencies, commercial entities focused on in-space manufacturing and research, and space-based research and development organizations.
