Space Station Extension May Cost More Than NASA Expects: Report

NASA’s anticipated $3 billion to $4 billion annual budget for the International Space Station is “overly optimistic”, a new report from NASA’s Inspector General says.

Transportation costs will likely rise when NASA uses commercial spacecraft to access the station instead of Russian Soyuzes, the report said. Also, if international partners don’t commit to extending the station four extra years to 2024, NASA will need to pick up more of the financial burden.

“While ISS program officials have been seeking ways to reduce costs and consolidate resources, it is unclear whether these efforts will be sufficient to address anticipated cost increases, particularly because the program does not expect to maintain any funding reserves over the next several years,” the report reads.

In January, the Obama administration approved NASA’s request to extend the ISS until 2024. At the time, NASA said the extension would be beneficial for science and also for the companies that will send spacecraft to the station, which right now appear to be SpaceX and Boeing. (NASA has been purchasing Soyuz seats since the shuttle retired in 2011, and U.S. flights are slated to start up again in 2017.)

There are 16 nations participating in space station operations, however, and any extension may require the approval of some or all of them. Political tensions with major partner Russia (which manages much of the station) have increased since the Ukrainian invasion crisis erupted earlier this year, prompting international condemnation. NASA cut most scientific ties with Russia in April, but preserved the station — an activity the agency says is proceeding normally, despite the crisis.

Besides political ramifications, the report points to technical issues with the ISS that could make an extension difficult. Its solar arrays are degrading faster than predicted, causing power limitations, and NASA has limited capability to lift large replacements parts to the station since the shuttle’s retirement.

Even the station’s promise of science return is proving to be a challenge. ISS United States laboratory manager Center for the Advancement of Science in Space (CASIS) is facing “issues related to funding and patent licenses and data rights” that are “deterring commercial stakeholders from conducting research on the ISS,” the report notes.

The report suggests that NASA keep trying to secure commitments from the ISS partners to share station costs, and that the agency “prioritize the human health risks to long-term exploration” in terms of its scientific research. While the report praised NASA for taking its recommendations seriously, it chastised the agency for not having a list of risks to the ISS ready yet.

NASA’s spending on the ISS was $2.9 billion in fiscal 2013, with 43% of that money going to system operations and maintenance, and 34% to crew and cargo transportation. About 10% is allocated to research.

    Scrapped the big trucks and privatized. And how is that working out, Congress?

    SpaceX and others are awesome, but they do not have the resources of nations.

    I wonder how this money pit continue to be beneficial for science and humanity , are there so many experiments left to do ?, except of making selfies and pictures from each other ?
    Is there no better way to explore space for science and humanity ?
    For example sending robots to other moons ?
    Or is this yet another excuse to make a few elite more wealthy.

    I can’t see the comments , logged in or logged off !

    And thus spake the bean counters. Wait a minute,private space launches are going to be more expensive than Soyuz? I expect they’ll be using ULA then

  5. BlackWolfStanding says

    Why can’t we put the space station at a Lagrangian point? That way we can vacate it until it is needed.

    I have tried everything I can think of w/o success.
    I see {N comments…read them below or add one} but, they are not displayed!
    It’s a catch22 as my message gets posted (counter increments) but those having this problem will not be able to see it to respond.
    If anyone had this problem and was able to resolve it, I would greatly appreciate some advice.
    Thanks, Bill e-mail is… [email protected]
