Space exploration is filled with unexpected challenges, but who could have predicted an allergy to the moon? Harrison Schmitt, an Apollo 17 astronaut, experienced this bizarre phenomenon. After walking on the lunar surface, Schmitt began to suffer from symptoms similar to hay fever when lunar dust entered the spacecraft. Sneezing, watery eyes, and a sore throat plagued him until the lunar dust was removed from the environment. Interestingly, Schmitt was the only Apollo astronaut to report such a reaction, making his experience truly unique. It's a reminder of the unpredictable nature of space exploration and the mysteries our universe holds. Stay sharp with Till.
