Question & Answer  

  • In response to a question by Chairman Babin, Mr. Bowersox outlined that key elements for CLD transition include the establishment of new private space stations, the development of the USDV, and continued utilization of the ISS until 2030. While exploring alternative options for retiring the ISS, a decision was reached that deorbiting the ISS was the most favorable course of action. The expenses associated with deorbiting the ISS will be distributed among partner nations according to used mass. 
  • In response to a question by Ranking Member Sorensen, Dr. Dittmar stated that Axiom’s private astronaut missions (PAMs) stimulate international and nongovernmental interest in human spaceflight, thus expanding the overall space market. Mr. Taylor echoed this sentiment, underscoring the “huge international demand” for private human spaceflight capabilities. He further stated that rather than solely addressing existing demand, private space stations are poised to generate additional demand, given current limitations on astronauts’ time for experimentation aboard the ISS. Mr. Taylor also cited the burgeoning demand for experimentation in LEO from the biopharmaceuticals industry.  
  • In response to a question by Rep. Bill Posey (R-FL), Mr. Bowersox stated that NASA would like to see improvement in the facilities and capacity of the Kennedy Space Center (KSC) and that potential legislative changes would allow NASA to take resource investment from private partners to support improvements at KSC. During a related line of questioning on utilizing foreign launch capabilities, Mr. Bowersox stated that NASA has no current concrete plans to do so.  
  • In response to a question by Rep. Posey, there was consensus amongst the witnesses that intellectual property aboard space stations is critical, and that due regard should be paid to protecting intellectual property when there are multiple actors within one station. Mr. Taylor said that there would be no Chinese activity on Starlab in response to threats to intellectual property.  
  • In response to a question by Chairman Frank Lucas (R-OK), Mr. Bowersox outlined NASA’s strategy to serve as an ‘anchor tenant’ aboard CLDs, with the intention to stimulate the market and then gradually reduce its own role as a customer over time. Mr. Taylor expanded on this, suggesting that the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), and the Canadian Space Agency (CSA) could also potentially serve as anchor tenants. 
  • In a response to a question by Rep. Rich McCormick (R-GA), Dr. Dittmar expressed concerns regarding the bifurcated nature of the White House mission authorization proposal, specifically noting the split regulatory responsibilities between the Department of Transportation and the Department of Commerce and the potential delays that could result from interagency coordination. She emphasized the importance of streamlining regulatory frameworks and agreed that it would be more beneficial for the industry to engage with a single government entity serving as a “one-stop shop.” 
  • In response to a question by Rep. Daniel Webster (R-FL), Dr. Dittmar contended that the lack of a definite end-of-life date for the ISS hinders the commercial development of LEO by introducing uncertainty for investors. She recommended keeping the ISS operational until a commercial alternative is viable. Mr. Bowersox reiterated NASA’s commitment to initiating the deorbiting of the ISS in 2030, noting that Russia is committed to supporting ISS operations until 2028 primarily due to their budget cycle.  
  • In response to a question by Chairman Babin, Mr. Bowersox discussed mechanical concerns with respect to the Russian segments of the ISS, emphasizing the strong cooperation between NASA and Roscosmos on these issues. He stated the Russian modules are providing valuable data regarding spacecraft aging. When speaking about the recent coolant leak on the Russian module, he stated that “the orbital debris environment is something that’s a big issue for all of us, including our Russian colleagues.”
