SEATTLE — With the International Space Station (ISS) scheduled to retire in 2030, NASA is placing a huge emphasis on a seamless shift to future private space stations in low-Earth orbit. Many details of that transition are still being worked out, agency officials say.

"The reason this is so important is because we do believe that the impact of a gap will be disruptive," said ISS director, Robyn Gatens, during a panel discussion at the International Space Station Research and Development Conference earlier this month.

A few key players who could be impacted by that "gap" include scientists looking to send research experiments to space as well as crew and cargo transportation providers. Given NASA's expected two-year transition period, a commercial successor must be operating by 2028 to prevent any such complications.

To plan for a smooth shift of research and operations to private space stations by 2030, the White House Office of Science and Technology Policy issued a strategy in March of this year that outlines a plan of action. The policy's overlying objective is for the U.S. to lead in "an emerging marketplace run by commercial and private enterprises engaged in LEO," ultimately allowing NASA to maintain an "uninterrupted U.S. presence" in low-Earth orbit.

"The reason we at the White House level released a policy on this topic this year is to prepare seven years in advance, so that we do not have to plan for a scenario where there's a gap," Ezinne Uzo-Okoro, an assistant director for space policy at the White House Office of Science and Technology Policy, said at the conference.

Because commercial space station services is still an unproven market, however, carrying out such a seamless transition will not be without its challenges. For instance, experts will need to worry about things like technical costs and scheduling risks in terms of design and development of the space station platforms, John Mulholland, the Boeing program manager for the ISS program, said at the conference. "They will get there but it will not be easy."

Mulholland also underscored the need for increasing the budget for the United States Deorbit Vehicle (USDV), a spacecraft expected to dock on the ISS before performing a safe deorbit and re-entry sequence back to Earth. (NASA is expected to award the contract for the design and production of this vehicle in March 2024).

The new funds are also likely to be used for an upgrade that significantly improves the science capability of a physics instrument on the ISS that hunts for dark matter, cosmic rays and antimatter galaxies. The detector, known as the Alpha Magnetic Spectrometer (AMS), was installed as an external module on the ISS in 2011. Its upgrade is expected to take an entire cargo flight, which "deserves a plus-up in the budget ahead," Mulholland said.

With a majority of the research on the ISS funded by the federal government, and the Fiscal Responsibility Act of 2023 suspending the debt ceiling until the end of 2024, "we will be faced with difficult budget cycles in the near future," he said.

Angela Hart, manager for NASA's Commercial Low Earth Orbit Destinations (CLD) program, said the space agency will pass on its expertise in technology to private space station providers, but such responsibility and involvement will decrease as the latter finds surer footing. Over the next year, NASA will focus on working with partners and the science community to avoid cost overruns and schedule issues, she explained during a talk on Aug. 3.

After the ISS retires in 2030, NASA is likely to operate a national laboratory that would support various commercial platforms. Although details are few, the LEO National Lab, which is still a working name referring to "low-Earth orbit," is expected to represent all government-sponsored research to be carried out on a combination of available private space stations.

"The idea is that it would be platform agnostic. So it's not a single place, it's not a single laboratory," said Gatens. "One really important tenet that we're looking at is it needs to support but not compete with commercial platforms and service providers."

Currently, ISS partners including Japan, Canada and the European Space Agency (ESA) have committed to support the ISS until its phased retirement operation planned for 2030. Russia has confirmed its support only until 2028, however, after which it will focus on building its own orbital space station, whose first module is expected to launch in 2027.

    It was somewhat disconcerting to read through this article and find that it says nothing about the schedules for any of the potential commercial LEO space stations.

    At least Boeing is not one of those planning one, which is a relief, considering how delayed Boeing has been on its recent space deliverables.

    But, with SpaceX not planning a space station, it seems like it will be up to some of the less successful groups to get this done.

    Any "gap" in the availability of LEO access from the U.S. will just hand the business from the rest of the world over to China. Russia might also be a contender for that business, but that will depend on how the Ukraine war plays out over the next several years.

    Like so many other NASA and combined space projects, the ISS was a huge waste of time, money, and resources. If all that had been applied to building a proper space station, the basic main framework and several working sections would now be up there. Instead of retiring the ISS and replacing it with even more limited use stations, we could be expanding a REAL Space Station, like Space Station 5 envisioned in 2001 A Space Odyssey.

    Simply put Elon Musk on the case and it will get done economically and done right. The beaucracy could not even keep US with a manned space launch program. Use an organization with proven record of success. Easy, done.

    Nasa IS AN ANTIQUATED piece of work. They certainly have reached their level of incompetence. Retire them in Florida with my Dad who has retired from NASA. Leave it to Elon.
