Secondary Hazards



During the Apollo 7 mission, astronauts fell ill with colds due to mucus build-up in microgravity, prompting discomfort during helmet wear and fear of pressure changes during re-entry. NASA implemented a two-week pre-launch quarantine, yet viruses still reach space, with the International Space Station harboring various strains, including dormant ones that can reactivate and spread contagiously. Ultraviolet radiation exposure is suspected to reactivate viruses, posing challenges for healthcare on Mars, where a continuous influx of new arrivals may exacerbate disease control efforts.


A virus can spread rapidly amongst the astronauts and strike down many at one time, severely hampering the colony and its ability to use the astronaut’s labor until they rest or seek medical attention. Viruses only impact astronauts and therefore may lead to brief spikes in medicine prices.
