Max Space
Country: USA
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.
