SpaceX is Elon Musk's leading space company, having achieved numerous advances in rocket propulsion, reusable launch vehicles, human spaceflight and satellite constellation technologies. It's the dominant global launch provider, surpassing all others in launch frequency. Its Falcon rockets launch 1-3 times per week. The company operates its own Starlink satellite constellation, which provides satellite internet worldwide. SpaceX also builds Dragon capsules for delivering human missions to the space station. It's building Starship, the largest launch vehicle in history, which aims to fully realize the company's vision of a fully reusable, cost-effective and adaptable launch vehicle. SpaceX is also developing its own spacesuit and astronaut as part of its Polaris program and human lander for lunar missions as part of the Artemis program.

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.
