Deleting Chinas chokehold over the USs defense industrial base and trillions of dollars of trade.

Samara Aerospace’s mission is to fundamentally change how satellites are designed with our Hummingbird satellite bus, enabled by the revolutionary new pointing control technology, called MSAC. MSAC allows us to not only make Hummingbird thinner, lighter, and more rapidly producible than alternatives on the market, but also bring levels of pointing performance currently only available to the James Webb Space Telescope to the commercial Earth orbit market. This will unlock next-level image quality for Earth observing satellites, higher data rates for space-based Internet, and increased launch capacity for our strained launch infrastructure.
