2024Star Catcher Industries develops an orbital energy grid that beams solar power to satellites in space.
Demand for power in orbit is growing faster than onboard generation: Star Catcher's own analysis projects the satellite population rising from 10,000 satellites drawing roughly 50 megawatts in 2025 to about 60,000 satellites drawing more than 1,000 megawatts by 2030, with the average satellite needing over 15 kilowatts against the roughly 1 kilowatt most buses generate today.
Analyst sizings put the addressable space energy market in its early stages: space-based solar power estimates range from about USD 630 million in 2025 toward USD 4.61 billion by 2041 at roughly a 13% CAGR (Mordor Intelligence), while Fortune Business Insights projects the broader space power supply market growing from USD 3.46 billion in 2025 to USD 6.51 billion by 2034, with terrestrial data-center demand growth the driver behind orbital ambitions.
Star Catcher's differentiation rests on a beaming approach that requires no customer hardware changes: the Star Catcher Network transmits concentrated solar energy directly to satellites' existing solar arrays, which the company states can scale a satellite's available power by up to 10x without retrofit. The company reports the world record for optical power beaming, set in demonstrations at NASA's Kennedy Space Center, and completed the Sextant Alpha on-orbit acquisition and tracking demonstration in late 2025 ahead of its Protostar power node launching on SpaceX's Transporter-18 mission.
Commercial traction is the second advantage the company points to: ten announced commercial power purchase agreements with customers including Starcloud, Loft Orbital, Astro Digital, and Aethero, plus more than forty letters of intent, a $60 million US Space Force STRATFI award, and $88 million in venture funding raised to date, supporting a 100,000-square-foot headquarters build-out in Jacksonville.
The economic case for space solar power remains unproven at scale: a January 2024 NASA study projected baseline lifecycle costs of $610 to $1,590 per megawatt-hour for two space-solar concepts, 12 to 80 times more expensive than terrestrial renewables at $40-$80 per megawatt-hour, with competitiveness requiring launch costs near $500 per kilogram and hardware lifetimes around 15 years. Beaming companies also face certification, safety, and pointing-precision questions that on-orbit demonstrations like Star Catcher's Protostar mission are only beginning to test.
The field is also crowded with better-capitalized rivals pursuing related approaches: Aetherflux raised $275 million in May 2026 and demonstrated space-to-Earth laser power beaming at White Sands; Overview Energy holds a $20 million seed and plans a GEO constellation in 2027; and Virtus Solis, working with Orbital Composites, targets a 2027 demonstration. Star Catcher's space-to-space focus limits its initial customer set to satellite operators, though it avoids the harder ground-reception problem its rivals face.
