ISSasema

ISSasema is a fictional international space station concept described in speculative policy analyses and science fiction. It envisions a modular research platform in low Earth orbit designed to extend human presence beyond the capabilities of the current space station. The name ISSasema is a portmanteau used in discussions to denote an advanced, cooperative orbital laboratory.

Origin and concept: The idea emerged in discussions during the mid-2020s among researchers, industry partners, and science communicators as a possible successor to the International Space Station, intending to host long-duration crews and to test technologies for deep-space missions. It is presented as addressing aging ISS infrastructure, enabling sustained microgravity experiments, and advancing in-space manufacturing and life-support systems.

Design and capabilities: The proposed design centers on modular habitat modules connected by standardized docking adapters, with flexible laboratory racks, and autonomous servicing capability. A power and thermal subsystem based on high-efficiency solar arrays and closed-water cooling is envisioned, along with regenerative life support and AI-assisted operations. The station would feature multiple docking ports to support visiting vehicles, robotic arms for maintenance, and on-orbit maintenance demonstrations.

Operations and program context: Typical crew sizes are envisioned at four to six astronauts with missions ranging from several months to a year. Scientific programs would span biology, materials science, human research, and space technology demonstrations, including manufacturing experiments in microgravity. The concept emphasizes international cooperation, cost-sharing, and potential integration with other orbital platforms.

Status: ISSasema remains a hypothetical concept used in speculative writing and policy discussions; it has not progressed to a formal program. Related topics include the International Space Station, Lunar Gateway, and commercial space stations.
