We are grateful for the opportunity to respond to the recently submitted commentary engaging with our review article, Medical Ethics of Long-Duration Spaceflight. Scholarly critique is an essential part of developing sound ethical frameworks in this nascent and rapidly evolving field. We offer this reply to clarify several philosophical misinterpretations and respond to critiques that, in our view, reflect a misunderstanding of both our intentions and the scope of our article.
Given the increasing involvement of female astronauts in advancing our knowledge of human capacity for long-duration spaceflight, it is critical to determine how to ensure their health and safety, as well as optimize their performance. This commentary discusses the priority to leverage the strengths of innovative collaborations and scientific approaches to enable the identification of potential risks and establish effective countermeasures that will ultimately support the success of space exploration.
Private space missions such as Polaris Dawn exemplify the challenges facing the evolving landscape of space exploration. Polaris Dawn involved high-risk groundbreaking elements that included the first commercial spacewalk. Here, we draw attention to the fact that private spaceflights, while exciting, also have potential ramifications on government-sponsored space programs, highlighting the need to think about acceptable risks for such missions in the broader context of US space policy and funding.
