ESA asks for proposals on building its own space station
The European Space Agency (ESA) last week issued an open call for proposals outlining the construction of its own space station, independent of the five American stations presently in development to replace ISS.
On 27 February, ESA published an intended call for tenders for two Pre-Phase A studies under Scenario 3. According to the call, the studies will consolidate the “feasibility, architecture, utilisation, and technology requirements of a European-led LEO outpost” and propose cooperation with the Canadian Space Agency, Japan’s national space agency JAXA, and “additional partners.” The results of the two parallel studies will be used to enable ESA decision-making for its post-ISS transition by the end of 2026.
Do not expect these “studies” to produce a European-led space station any time soon. It is the ESA way to do lots of studies, and then after reading these to do more detailed follow-up studies outlining what they will do. Then, after years of review, it might finally get started on construction, which always proceeds somewhat slowly.
In the meantime, ESA has signed agreements with three of the five American space station projects (Axiom, Starlab, Vast), with its deal with the Starlab station the most extensive. All three deals leave open the possibility that Europe will rent time at each station to fly experiments and astronauts there.
