If you saw Gravity, you have an idea of what a disaster in space might feel like to an astronaut: terrifying, alienating, and utterly overwhelming. But as NASA ponders the future of its space program, which will probably include high-risk missions and long-duration flights (like, oh, say, a trip to Mars!?), how can they determine when a risky mission is too dangerous? To help answer that tricky ethical question, they turned to an Institute of Medicine committee, chaired by  Johns Hopkins bioethics professor Jeffrey Kahn.

โ€œFrom its inception, space exploration has pushed the boundaries and risked the lives and health of astronauts,โ€ Kahn said. โ€œDetermining where those boundaries lie and when to push the limits is complex.โ€

According to Kahn, the IOM report lets NASA know in no uncertain terms that if the agency attempted to relax its health and safety standards for long-duration flights, that would be โ€œethically unacceptable.โ€

โ€œAstronauts put their lives and health at great risk for their country and humankind,โ€ Kahn said, noting that the agency had an โ€œethical imperative to protect astronautsโ€™ healthโ€ while also fulfilling its mission of exploration.

In other words, just because a mission is really cool and exciting (Mars!!!) doesnโ€™t mean ethical standards are thrown out the window. NASA needs to take into account the health risks astronauts faceโ€“which include vision impairment, bone loss, behavioral changes, increased cancer risk, and being really sad because you miss George Clooney.
