Star Catcher's Satellite Power Test Marks First Step Toward Wireless Space Energy

Florida startup Star Catcher completed its first in-space laser power transfer between satellites, advancing wireless space energy systems.

Star Catcher, a Florida-based startup, conducted its first in-space test of laser-based wireless power transmission between satellites on October 1, 2026. The prototype system, named Protostar, successfully transmitted power from one satellite to another—a milestone for space-based wireless energy. While the test delivered 1.1 kilowatts to NASA’s Kennedy Space Center in 2025, Star Catcher claims its technology could generate up to 10 times more power than standard solar panels by using solar lenses, laser conversion, and transmission to spacecraft panels. The startup has signed 10 power purchase agreements and received over 40 letters of intent for commercial services, signaling early industry interest. However, this remains a prototype demonstration, not operational deployment. The technology aims to extend satellite lifespans and free up space for critical hardware by reducing battery and solar panel needs.

The mechanism hinges on precise laser targeting and solar energy conversion, but challenges identified by Max Planck Institute researchers—including thermal management and long-term equipment durability—highlight the path ahead. For now, Star Catcher’s follow-up satellite targets 'operational levels of power' for other spacecraft, but real-world validation against space conditions remains unproven.

This advancement could eventually lower costs for space-based services that support Earth, like satellite internet and climate monitoring, by eliminating reliance on Earth-dependent grids. If scaled, it might reduce the energy burden on aging satellites while enabling more efficient space infrastructure. What matters next is whether thermal and targeting challenges can be resolved to meet commercial power demands—especially since current tests fall short of requirements for large satellites.

*Note: The October 1, 2026 test represents a prototype system demonstration, not operational deployment. The 1.1 kilowatt ground test is below power requirements for large commercial satellites. Star Catcher’s claims of 10x power increase require validation against real-world space conditions. The technology has not yet been deployed at scale for commercial operations.*
