The brief

Analyst view

• ForgeStar-1 launched June 2025 and reached 1000°C in orbit, validating on-orbit semiconductor manufacturing.
• Satellite operates at 480 km altitude for 1-6 month missions, growing crystals in microgravity.
• ForgeStar-2 targets 10-12 flights per year, producing materials worth more than launch cost.

Technical approach

As reported

Furnace

1000°C in orbit

ForgeStar heats a furnace to 1000°C to grow crystals and semiconductors in vacuum and microgravity.

Reusability

Return and refurbish

Satellites return from orbit for refurbishment and relaunch, reducing cost per mission.

Payload

Commissioned materials

Each mission grows customer materials for pharma, semiconductor and specialty companies.
