Sick astronauts could contract infections on Mars in some sections of the spacecraft that are on life support. Earth may be reluctant to welcome such travelers, as they may carry a disease that could cause extraterrestrial super-pandemics.
NASA is already considering this issue for humans expected to orbit Mars in the mid-2030s. "The key is to ensure rigorous health screening of astronauts throughout every phase of a Mars mission and deep space mission," said Cassie Conley, a NASA Earth Protection officer.
