Have you ever wondered what space smells like? Here’s what astronauts think

Must read

Everyone knows that most of space is empty, completely devoid of anything: no dust, no planets, and not even air. Hence why many people who have the privilege of swimming in the cosmosthe universe has a smell?

Let me be frank, no astronaut in outer space took off his helmet; however, these did report a strange smell once set foot gea. Specifically, inside air locks that cosmonauts recognized more than one scent returning from a voyage to the stars.

The best definition I could find is metallic; metallic-sweet feeling pretty nice”, wrote astronaut Don Pettit. “It reminded me of college summers where I worked long hours with a welding flame repairing heavy equipment. It reminded me of fragrant profound fumes. it’s the smell of space.Pettit is an absolutely top-notch witness, having participated in several EVAs (extravehicular activities in space) during his career at NASA.

Other space adventurers have described the scent similarly: “burning metal”, “a pronounced ozone odor, a pungent odor”, “nuts and brake pads” And “gunpowder”. Although each person comes up with different recipes for the smell of the cosmos, they all have one thing in common: burnt smell (contrary to what has been said in the past). So why are these olfactory notes perceived?

One explanation has to do with oxidation from the pressurization process. balance chamber. The aforementioned chemical reaction involves oxygen atoms from space attaching themselves to the astronaut’s suit and then floating in it. When? balance chamber opens, then these combine with atmospheric oxygen. This process is similar to flameless and smokeless combustion, so cosmonauts smell like they’ve been burned.

However, a second hypothesis appeals to the explosions of dying stars. The estimated age of our Solar System is about 4.5 billion years; According to the Hubble constant, the Universe will be about 13.7 billion years old. In this 9.2 billion year difference, many stars were born and exploded. After a celestial body dies, the named compounds are dispersed in space. polycyclic aromatic hydrocarbons (IPA) is also present on our planet. They are also released by the combustion of tobacco, wood, meat and other substances.
