Often in the reporting about science, the adventure, the risk and the physical difficulty of the research gets shunted aside and ignored. Science tends to be seen as the work of people who don't willingly expose themselves to physical hardship and danger.
Exceptions to this perception, including astronauts and heroic researchers such as Jonas Salk (who famously took an early dose of the polio vaccine, along with his wife and children, to hopefully demonstrate its safety), are few and far between.
