NASA harbors a trailblazing initiative known as the Collaborations for Commercial Space Capabilities 2 (CCSC2), which is a visionary program designed to bolster the commercial development of space. This initiative strategically allies the space agency with corporate entities and private organizations. Unlike more formal, practical programs that follow, CCSC2 is unique in that it activates without direct financial backing from NASA. Instead, the agency supports partner companies by sharing its wealth of experience, technologies, data, and guidelines.
In one of the latest cycles of the CCSC2 program, NASA has embarked on a collaboration with SpaceX to further the commercial prospects of the latter’s Starship spacecraft, alongside partnerships with seven other firms. A document from NASA (since SpaceX’s documents are not public, whereas NASA’s must be disclosed eventually) has recently surfaced, detailing a timeline for the commercial development of low Earth orbit (LEO) activities. For instance, it pinpoints the beginning of 2024 as a tentative date for Starship’s maiden voyage with a payload on board. Notably, this timeline is specific to LEO development and does not encompass Starship’s role in the Artemis program or lunar missions.
Emerging details suggest that SpaceX envisions Starship not just as a vehicle but as a space station in its own right, with operational service projected to commence in the early 2030s. Starship is envisaged to offer a habitable space of roughly 1,000 cubic meters—slightly more than the current pressurized volume of the International Space Station (ISS), which is about 950 cubic meters. These figures, while tentative and based on the prototype’s design, which is likely yet to be finalized, give a comparative glimpse of Starship’s potential scale.
Per NASA’s documents, an imminent milestone for this ambitious project is the year 2028, when SpaceX is expected to deliver a Preliminary Design Review (PDR) of the concept.
The Potential of a Starship Space Station
The promise of Starship as a space station lies not only in its size but in its versatility. Awaiting its second test flight, slated for September 2023, Starship is already conceptualized to serve multiple roles: a cargo launcher, a crew capsule for orbiting Earth, lunar voyages, and missions to Mars. It’s also being considered for use as a lunar lander and for point-to-point cargo transportation on Earth.
The addition of a space station to its repertoire is perhaps one of the more obvious evolutions for Starship. Its design lends itself to modification and adaptation, as evidenced in the past with Skylab—America’s first and only space station to date, which was crafted from a repurposed Saturn V rocket stage.
This latest iteration of Starship underlines the project’s adaptability and suggests that despite the intense scrutiny on Starbase—SpaceX’s construction site—several non-public iterations, updates, and modifications are potentially in the works.The aforementioned document, dating back to May 2023, when it was sanctioned, outlines initial steps. Moreover, an important dossier is anticipated this fall, drafted by NASA based on SpaceX’s insights. It will assess the status and forthcoming phases of Starship’s lunar variant, a critical component of the Artemis program.
This partnership exemplifies a significant stride in commercial space endeavors, signifying a shift from governmental to private-sector leadership in space exploration. With NASA’s seasoned guidance and SpaceX’s innovative drive, the boundaries of space commercialization are set to expand, potentially bringing about a new era of space stations and interplanetary travel.
