How does space smell like?
i think it smells like nothing because there is nothing in space so it does not smell anything
If there is nothing there to smell there must be no smell.
I would think that if Cris Hadfield smelled burnt steak in space someone sitting next to him must be eating or cooking steak. Was he in space recently? Where and under what conditions. Space is void; there is nothing there. It is a vacuum but an imperfect vacuum since there may be space dust and debris from nearby plants/moons, etc. But if you stick to space being a vacuum there just isn't anything in a vacuum.
That's a common misconception! Technically, space is a vacuum, meaning it doesn't contain matter like gases or particles that could carry smells. So astronauts in space cannot directly smell anything like we can on Earth.
However, when astronauts return from a spacewalk or open the hatch of their spacecraft, they sometimes report a distinct odor. This smell is often described as a "metallic" or "burnt" scent. It originates from various factors, including the outgassing of materials in the spacecraft, the lingering scent of rocket propellants, and even the spacesuits worn by astronauts themselves.
It's important to note that this scent is not actually coming from space itself, as there is no air or medium in space for odor particles to travel through. Instead, it is the result of human-made materials reacting and releasing molecules into the confined environment of the spacecraft.
