In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.
1. Unless there's a source of heat nearby, the body will be quickly frozen, and decomposition will take thousands or even millions of years. 2. If there's heat, but no spacesuit or spacecraft, the body will very quickly dry out, because water evaporates extremely quickly in the vacuum of space.
Bones and muscles weaken
In space, where gravity is very weak, posture can be maintained without standing on your legs, and there's no need to use your legs to move about. Muscles weaken and bone mass decreases if you stay for a long time in space.
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly … low. The two worst disasters both involved NASA's space shuttle.
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...
First, the good news: Your blood won't boil. On Earth, liquids boil at a lower temperature when there's less atmospheric pressure; outer space is a vacuum, with no pressure at all; hence the blood boiling idea.
Is Laika the dog still in space? No, Laika is not still in space. After orbiting the planet over 2,000 times, Sputnik 2 eventually fell back to Earth in 1958.
In the vacuum of space, gas exchange in the lungs continues as normal but results in the removal of all gases, including oxygen, from the bloodstream. After 9 to 12 seconds, the deoxygenated blood reaches the brain, and it results in the loss of consciousness.
Why can't we see stars in the pictures of spacewalking or moonwalking astronauts? The stars aren't visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
Astronauts who have stayed in space for long periods have problems with their circulation and eyesight. That's in addition to losses in bone and muscle tissue. Kelly has collected fluid samples and undergone rigorous medical testing to document these changes over the course of his trip.
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
During the launch, her pulse shot up to three times its normal rate and she was so terrified that it remained elevated for an extended time. Temperatures inside the tiny spacecraft quickly soared, and within hours, she cooked to death—all alone and in severe pain. What Laika was subjected to was cruel and inexcusable.
With a pounding heart and rapid breath, Laika rode a rocket into Earth orbit, 2,000 miles above Moscow streets she knew. Overheated, cramped, frightened, and probably hungry, the space dog gave her life for her country, involuntarily fulfilling a canine suicide mission.
Clara Glen Pet Cemetery
At the center of the cemetery is the War Dog Memorial that honors the dogs that served in World War I and is encircled with tributes to the space dog Laika (who is not buried in the cemetery), as well as the dogs who helped with search and rescue following the Oklahoma City bombing in 1995.
One explanation is that the smell is due to a chemical reaction which occurs within the spacecraft during re-pressurisation. The process is known as oxidation—similar to burning but with no smoke. In space, atomic oxygen (single atoms) can cling to a spacesuit's fabric, to tools and potentially even to air-lock walls.
Upon sudden decompression in vacuum, expansion of air in a person's lungs is likely to cause lung rupture and death unless that air is immediately exhaled.
No, there isn't sound in space.
This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
After a week in orbit, the Los Angeles Times reported, she would be fed poisoned food, “in order to keep her from suffering a slow agony.” When the moment came, Russian scientists reassured the public that Laika had been comfortable, if stressed, for much of her flight, that she had died painlessly, and that she had ...
Laika was a stray dog found on the streets of Moscow. There were no plans to return her to Earth, and she lived only a few hours in orbit.
However, unlike modern cosmonauts, her return was never planned for. According to the Soviets the plan was to euthanize Laika with medicated food just before reentry. Sadly this humane method didn't pan out. Laika's vital signs stopped after 5-7 hours in orbit.
Laika died a few hours after launch from stress and overheating, likely due to a malfunction in the thermal control system. The true cause of her death was not made public until decades after the flight. Some former Soviet scientists have since expressed regret that Laika was allowed to die.
To date, no astronaut has ever been 'lost' to space during one, but there have been a couple close calls. When outside their spacecraft, astronauts attach themselves to the hull with tethers made of heavy-duty materials like kevlar.
Ultimately, while astronauts' salaries are generally modest while they're working, they can still sometimes get a hefty payout once they retire from active duty. In short: no, astronauts do not get paid for life.
People in a coma will not age like conscious people living life. Muscles weaken & emaciate. The damaged part of the brain might deteriorate as a result of inflammation to the area.
Astronauts are paid according to the federal government's General Schedule pay scale, and they can fall on the GS-11 through GS-14 pay grades. The pay grade is based on an astronaut's academic achievements and experience. The starting salary for GS-11 employees is $53,805.
