Astronauts Reveal What Life is Like on the ISS – and How They Deal with the 'Space Smell'
Space Smell Explained
Upon arrival at the ISS, astronauts are often hit by what they describe as a “peculiar odor.” According to astronaut Samantha Cristoforetti, the smell can be startling at first but becomes unnoticeable after a few days. While the exact odor is difficult to describe, astronauts compare it to burnt metal or ozone, which likely results from atomic oxygen clinging to spacesuits after spacewalks. The space station’s air filters help manage odors, but certain areas, such as the trash-packed cargo freighters or the toilet system, can still emit strong smells.
The Daily Life of Astronauts
On the ISS, the crew follows a strict routine to ensure they stay fit and healthy in microgravity. With exercise being crucial to counteracting muscle atrophy and bone density loss, astronauts work out for two hours daily using specialized equipment like treadmills and the Advanced Resistive Exercise Device (ARED).
Adjusting to Life in Space
Sleeping and basic hygiene on the ISS also come with unique adaptations. Astronauts sleep in small crew cabins inside sleeping bags that prevent them from floating. The challenge of sleeping in space is amplified by the fact that they experience 16 sunrises and sunsets each day.
