The PRSS Nuwa was an interstellar exploration vessel launched in 2718. Constructed under the direction of the Chinese state and affiliated scientific bodies, it represented one of the last large-scale, coordinated technological efforts undertaken on Earth prior to the Collapse. The vessel’s primary mission was to survey distant star systems identified as potential candidates for harboring life and, if viable, establish a long-term human presence beyond the Solar System.
Designed for a multi-millennial journey, Nuwa functioned as a self-sustaining mobile habitat rather than a conventional spacecraft. Its internal structure was organized around closed-loop life-support systems capable of recycling air, water, and organic matter with minimal external input. Agricultural modules provided continuous food production through a combination of hydroponic and synthetic cultivation systems, while ecological balancing units maintained atmospheric stability within the vessel.
The ship housed a controlled population composed of mission specialists, support personnel, and a substantial reserve of cryogenically preserved embryos to ensure long-term genetic diversity. Medical facilities were equipped for advanced surgical procedures, genetic screening, and limited biotechnological intervention, allowing for the management of disease and hereditary conditions over extended timescales.
In addition to its life-support infrastructure, Nuwa carried extensive scientific and industrial capabilities. Onboard laboratories supported planetary analysis, biological research, and materials science, while compact manufacturing systems enabled the production of essential tools, replacement parts, and structural components. Autonomous and semi-autonomous probes were stored for deployment upon arrival in target systems, allowing for remote assessment of planetary environments prior to direct human involvement.
The vessel also served as a repository of human knowledge. Archival systems preserved scientific, cultural, and historical records from pre-Collapse Earth, intended to support the continuity of human civilization in the event of successful colonization. Despite these provisions, the long-term success of the mission remained uncertain, as it depended on the ship’s ability to maintain structural integrity, ecological balance, and social cohesion over timescales far exceeding any prior human endeavor.
