Accidents, as they say, have a knack for striking when least expected, often in the most mundane of moments. One minute, you’re gliding serenely aboard a space shuttle, and the next, a cruel twist of fate ejects you from the cabin, casting you adrift into the infinite void of space. When misfortune strikes, it rarely pulls its punches.
If you’re lucky enough to be wearing a spacesuit, you might have around 7.5 hours of oxygen to sustain you as you drift aimlessly. But even that isn’t always enough to make it to safety. Eventually, you’ll suffocate, having drained the last of your suit’s water reserves through a straw. The only solace? The breathtaking view.
When death finally claims you, the bacteria within your body will set to work as they always do. However, their progress will be brief, as the limited oxygen inside your suit will be quickly depleted. Some anaerobic bacteria may soldier on, causing your body to ferment. But if your remains are exposed to relentless solar radiation, the decomposition process might stall, leaving you in a state of cosmic limbo for years—or even eons.
Over time, the relentless radiation will degrade your spacesuit, causing it to rupture. The sudden release of internal pressure will trigger a small explosion, scattering your decayed remains into the abyss.
Now, let’s consider a more harrowing scenario: you’re cast into space without a suit—just a pair of tattered boxers, threadbare socks, and an old bathrobe for company.
Based on experiments conducted in the 1960s, mishaps in decompression chambers, and tragic incidents like the Soyuz-11 mission, we can piece together your fate. During that ill-fated Soviet mission, a valve failure at an altitude of 170 kilometers caused sudden decompression, leading to the deaths of all three cosmonauts.
If you ever find yourself in this dire situation, here’s some advice: don’t hold your breath. Trying to retain oxygen will cause the expanding gases in your lungs to rupture them violently. Instead, exhale immediately or let the vacuum draw the air out. This will grant you a fleeting 15 seconds of consciousness before your oxygen-deprived brain shuts down.
During those seconds, you might experience some peculiar sensations. The moisture on your skin and in your mouth will begin to boil due to the lack of atmospheric pressure. This phenomenon was notably observed in 1966 when astronaut Jim LeBlanc accidentally experienced near-vacuum conditions while testing a lunar spacesuit. His saliva began to froth, and he lost consciousness after 15 seconds. Miraculously, he survived, making him the only human to endure near-complete vacuum and live to tell the tale.
If you lose consciousness in the vacuum of space, your body won’t burst like in Total Recall—that’s pure Hollywood fiction. Instead, nitrogen dissolved in your blood will form bubbles, causing your body to swell like a balloon. But fear not—you won’t pop, thanks to the remarkable elasticity of human skin.
Exposure to unfiltered solar radiation will scorch your skin, leaving you with severe burns. Within 90 seconds, your heart will likely succumb to ventricular fibrillation, marking the end of your life.
As for your remains? Without bacteria to break you down efficiently, decomposition will be painfully slow. If you’re near a star, the heat may mummify or char you into a brittle husk. In colder regions of space, you’ll freeze solid over 12 to 26 hours. Either way, your body could endure as a desiccated mummy or frozen relic for millions of years, silently drifting through the cosmos.
Who knows? Perhaps one day, an alien civilization will stumble upon your remains, marveling at the mysterious traveler who met their end in the great expanse of space.
