The Subcommittee on Space will now come to order. Without objection, the Chair is authorized to declare recesses of the Subcommittee at any time. Good morning. Welcome to today’s hearing titled ‘‘Human Spaceflight Ethics and Obligations: Options for Monitoring, Diag- nosing, and Treating Former Astronauts.’’ I recognize myself for five minutes and an opening statement. As a Nation, we have obligations to those we put in harm’s way. As a Congress, we have a responsibility to provide for the treat- ment of conditions caused by federal service. As a legislator that represents the Johnson Space Center and the Astronaut Corps, I have a duty to care for my constituents. Since the 1960s, the United States of America has asked its bravest to travel in space in service to their country. The govern- ment recognizes its obligation to care for those it puts in harm’s way in other instances. For example, we provide for the care of our veterans and our federal employees when their injuries are caused by their federal service. NASA currently provides treatment for active NASA Astronauts, and management and former astronauts are eligible for treatment of injuries sustained in their service through existing programs at the Department of Labor and the Department of Veterans Affairs. Over the last 15 years, several reports have highlighted the po- tential hazards of human spaceflight and the ethical obligations that we have as a Nation, and the additional steps that we might take and need to take to address gaps in meeting those obligations. From the dynamic launch environment to the unforgiving vacu- um of space, to the energetic reentry to Earth, human spaceflight has always placed astronauts in challenging environments. Even training for spaceflight carries significant risks. Up until recently, however, space travel was measured in days. Mercury, Gemini, Apollo, and the Space Shuttle program placed as- tronauts in space for relatively short periods of time. Now, with the completion of the International Space Station, our astronauts now spend months in space. The risks and potential impacts on our as- tronauts’ health are not always seen immediately. Captain Scott Kelly recently returned from the ISS after spend- ing 340 days in space on one mission. This put his cumulative time in space at 520 days. Extended missions like his are teaching us a lot about the long-term effects of human spaceflight. Weightlessness leads to osteoporosis and loss in bone density. Long-duration space missions also seem to impact vision, as 60 per- cent of ISS astronauts reported worsening eyesight. Furthermore, radiation exposure increases the likelihood
