NASA hopes to send humans to Mars by 2030 on a round-trip mission that could take up to three years—far longer than any human has ever traveled in space. Such long-term spaceflights could adversely affect certain cells in the immune systems of astronauts, according to a new study led by University of Arizona researchers.
