Sierra Space implements complex space projects, including satellite missions (using its own small, high-performance, and affordable satellites for in-orbit servicing) and space stations. The company also develops new technologies and systems for spacecraft, including solar-powered electrical systems, surface-mount technology to significantly reduce space power supply lead times, hypersonic engines and life support systems. Sierra's most famous product is the reusable Dream Chaser spacecraft, designed to deliver cargo and crew to and from the station. It is the only commercial spaceplane capable of takeoff and landing.

Max Space is developing expandable space habitat modules that offer lower cost, more living space and improved access to space. The startup plans to build a commercial space station, Thunderbird, capable of launching on a single Falcon 9 rocket. Unlike traditional inflatable structures, this model utilizes a specialized complex structure that expands in orbit to a volume of 350 cubic meters. Thunderbird is designed to permanently accommodate four people. Its key advantage is its adaptable interior: the crew can reconfigure the space for various purposes, from scientific experiments to orbital manufacturing. In addition to its role as a laboratory in Earth orbit, the developers envision Thunderbird as a habitat module for future missions to the Moon and Mars. The pilot launch of a fully operational space station is planned for 2029.
