K2 Space
Country: USA | Funding: $925.5M
K2 Space specializes in building large satellites that serve as platforms for multiple third-party modules. These satellites became possible with the advent of large launch vehicles like the Falcon 9. Their advantage is high reliability and lower launch/servicing costs for each individual module. This is important for commercial, scientific and defense applications. The company's first satellite, K2 Mega (scheduled for launch in 2026), can carry a payload of up to one ton. It' designed for multi-orbit operations, protected from the harshest conditions of the solar system and is engineered with redundancy and reliability techniques historically reserved for crewed spacecraft like Dragon and the Space Shuttle. Its $15 million cost was achieved through the development of new systems, such as power supply, attitude control, thermal management.
