What They Build
Manastu develops green satellite propulsion systems and associated technologies for safer, cleaner, and more controllable satellite operations.
Why They Matter
As orbital traffic increases, propulsion becomes a safety and sustainability problem as much as a mobility problem. Manastu matters because it is building a domestic answer in a subsystem where reliability, chemistry, and qualification all matter. The challenge is proving performance across enough missions to become a default supplier.
