In anticipation of long-term manned space missions -- several of which are penciled-in to Mars, Jupiter and Alpha Centauri in the next few decades -- government authorities are considering the possibility of requiring licensing for off-planet healthcare workers. The Interplanetary License (IPL) would permit physicians, nurses and rehabilitation therapists to practice aboard spacecraft, both during the voyage and also on the destination planet. Healthcare workers would be trained and tested in the unique requirements of medical procedures in a zero-gravity environment and prepared for the effects of physical changes due to space-time relativity. The proposed regulation does not cover conflict resolution should the licensing standards of the destination planets' inhabitants differ from Earthling standards. Nor does it cover insurance issues stemming from treatment of non-human life forms. In other words, Happy April Fools' Day. You may not be ready to practice on another planet, but in case you want to travel on this one, we've got rewarding travel nurse and therapist jobs across the US. You can also read more about nurse licensing and state boards here (on Earth). [+]
