Two or three times a month, Wolpe travels to NASA's headquarters in Washington. He has visited almost all the U.S. space centers. He also attends international conferences, writes papers, and sets guidelines for future space endeavors.
His latest NASA project, he said, is "developing new policies for long-duration flights" to Mars and the moon, which could start as early as 2020.
Wolpe works out ethical solutions that range from deciding what should be done with an astronaut who "becomes psychotic and attacks" the other crew members to working with Williams in determining the level of radiation to which an astronaut can be safely exposed, he said.
