It is important to acknowledge the contributions that were made by our BHP community, including flight surgeons and medical operations, researchers from the NSBRI, our external investigators, and many others as noted below. Their time and work in this risk area are critical for understanding and communicating what is known and unknown regarding the risks of, and their mitigation for, human space flight, particularly as NASA plans exploration missions to the moon and Mars. Such knowledge will enable the space agency to meet these future challenges and succeed.
