Humans sent out into space without a space suit would become unconscious in 15 seconds, and suffer permanent brain damage in just 4 minutes. The temperatures on Earth may dip to 32 degrees Fahrenheit on a chilly day. But in space, it can get down to 148 F below zero or rise to 248 F.
You would still die of course, but it would be by asphyxiation. Your blood holds enough oxygen for about 15 seconds of brain activity. After that you'd black out, with complete brain death following within three minutes.
An astronaut floating without a suit in space wouldn't survive, but their demise would happen within minutes, not within seconds, and it would be a gnarly exit, with boiling bodily fluids and a nearly frozen nose and mouth. Related: Why is space a vacuum?
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.
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.
It's estimated that the heart, blood vessels, bones, and muscles deteriorate more than 10 times faster in space than by natural aging.
Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit — you'd die of asphyxiation or you'll freeze. If there's any air left in your lungs, they will rupture.
Even if you were dropped off in deep space where a thermometer might read 2.7 Kelvin (-455°F, the temperature of the “cosmic microwave background” leftover from the Big Bang that permeates the Universe), you would not instantly freeze because heat transfer cannot occur as rapidly by radiation alone.
REAL SPOILER ALERT: The short answer is that the lack of oxygen would make you black out after about 15 seconds. Then by about 90 seconds you are too far gone to be saved. So you would die from lack of oxygen well before the radiation and cold would have time to kill you.
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.
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.
The ISS orbits the earth at speeds of approximately 17,000 miles per hour, which is considerably faster than the earth rotates on its axis. Therefore the solar day on the ISS is considerably shorter than the earth day at just over 90 minutes in duration.
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.
Common items like salt and bread are banned from the International Space Station due to fears that they'll send floating pieces everywhere and potentially damage space equipment or accidentally get inhaled by astronauts. Basic eating, sleeping, and showering habits must also be modified.
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.
This leaves only high-energy blue light to be reflected from our maroon veins. So, if you cut yourself in space, your blood would be a dark-red, maroon color.
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
During spaceflight. As of March 2021, in-flight accidents have killed 15 astronauts and 4 cosmonauts, in five separate incidents. Three of them had flown above the Kármán line (edge of space), and one was intended to do so. In each case, the entire crew was killed.
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.
Salary estimates based on salary survey data collected directly from employers and anonymous employees in Australia. An entry level astronaut (1-3 years of experience) earns an average salary of $63,414. On the other end, a senior level astronaut (8+ years of experience) earns an average salary of $107,983.
Because of its close proximity to the black hole, it experiences tremendous time dilation, with one hour on the faraway planet equaling seven years on Earth.
Whitson, who compared traveling in space to a "camping trip," said urinating in an International Space Station toilet is easy. Pooping is very different. "Number two... is more challenging because you're trying to hit a pretty small target," Whitson told Business Insider.
