No, space, in general, does not smell like eggs. However, the upper atmosphere of Uranus does.
While the vacuum of space itself is odorless, astronauts who have returned from spacewalks or lunar missions have reported various scents clinging to their suits and equipment. These smells are not typically described as being like eggs.
Here's a breakdown:
-
Apollo Missions: Astronauts described the smell as similar to gunpowder.
-
International Space Station: Some have compared the odor to burnt steak, hot metal, or welding fumes.
-
Uranus: The upper atmosphere contains hydrogen sulfide (H₂S), the same compound that gives rotten eggs their distinctive smell. This is due to the high concentration of hydrogen sulfide in Uranus's atmosphere.
Therefore, while some regions of space could technically smell like rotten eggs, depending on their chemical composition, the sensations experienced by astronauts don't align with that smell. It's important to distinguish between the vacuum of space, the surfaces of celestial bodies, and the atmospheres of planets.
