Safety requires the right culture

October 31, 2018

Russia’s botched launch last month of an astronaut and cosmonaut to the International Space Station was good news in that no one died, and in another sense too. NASA and Roscosmos received a non-fatal wake-up call about spaceflight safety. Those involved in this brush with tragedy should dig below the proximate technical causes of the failure of the Soyuz rocket to examine cultural factors. James Oberg, a Houston-based space expert, explains.

Mission planners are now fully coming to grips with the twin hazards posed to astronauts by long durations in weightlessness and exposure to cosmic radiation. Scientists and engineers are working on faster propulsion technologies to cut down on trip time, as well as a suite of countermeasures, aimed at bringing the red planet safely within human reach.

The circumstances that led the U.S. to undertake the Apollo 11 lunar mission 50 years ago next July, and the five landings that followed, were unique, and they won’t be repeated. Even so, space historian John M. Logsdon sees reason to anticipate that U.S. astronauts will in the next decade return to the moon.
