Well, I don't think it is forbidden, but it doesn't happen. 1. The logistics of such act alone... The station might seem big, but it is actually quite small. Finding place to be alone is challenging. 2. Physics is a
They are not constantly talking, in fact they could go a long time without the need to interact with ground.If you talk about the ABILITY to talk with ground, that depends, as a previous answer stated, on the TDRS satellites
Are astronauts on the ISS paid while in space, or they are paid upon return or their families enjoy their pay cheque while they are in far away space?
Those who are active-duty military members continue to receive their normal military pay commensurate with that paid out to any other servicemember of the same paygrade. Civilian employees of NASA are paid as civil servants, in paygrades GS-11 to GS-14, and get the same amount as
Yes, they are constantly monitoring tests that universities, science companies, and NASA itself pays to have these tests done in micro gravity.Anything from growing modified plants from seed in weightlessness, to creating perfect ball bearings for industry, rounder than possible in a
Astronauts (or anyone who has close contact with an astronaut), what are some of the false perceptions we have of the earth which unexpectedly become apparent when one has been in space?
The one consistent theme astronauts like to share is that we on Earth live in a world of maps, where lines clearly delineate one state from the next or one country from another. Often the land areas are marked in different colors to further highlight their separateness. But
Astronauts most certainly can cast their vote from the International Space Station (ISS). As a matter of fact, I did just that in 2007! And making voting from space even more cool (at least to me anyway) is the fact that my beautiful bride
Yes. I think many of the people posting here are under the false impression that Soyuz modules drop off our astronauts, then return to earth without leaving any Soyuz modules attached to the station. The ISS has at least one Soyuz Module attached to
Can astronauts urinate while they're standing in space without getting themselves into too much trouble?
As Ernest mentions, on the ISS you pee into a hose so leakage is avoided. It is captured and filtered by the Waste Hygiene Compartment.If you're asking what would happen if you didn't use a hose - yes, it would get messy fast.
Unapproved electrical hardware cannot be transported on the Soyuz or used onboard ISS, so the crew do not bring their own devices. However, there are portable electronic devices onboard the ISS. For example, there are iPod Nanos that can be used to listen to music while exercising. There are iPads that are being used as an experiment
Absolutely.If you are asking a relativity question - then realize they are travelling a tiny fraction of the speed of light. So ultimately they may age a few seconds less than someone one earth after a long mission, the effective from relativity is essentially negligible. You could argue they age faster since
Yes. Here's a quote from astronaut Don Pettit:INTERVIEWER: When you dream in space, do you start dreaming in zero G?PETTIT: Yes. When I'm on Earth, I dream frequently about flying, and I don't have to flap my arms. I just kind of lean back, and
Maybe not insanity, but Buzz Aldrin ran into plenty of problems back on Earth after Apollo 11.From a review by Thomas J. Burns of Aldrin's book, Magnificent Desolation: The Long Journey Home from the MoonAldrin was an alcoholic, most likely before Apollo XI and certainly afterward, but the astronaut
Do astronauts need passports when they travel to space/leave Earth? Shouldn't they, at least when their mission could imply them having to land on Earth in any territory which isn't their own?
Astronauts do NOT need passports or visas when they leave Earth and travel into outer space... at least they don't at this time in our history.On a slightly related note, a good U.S. Astronaut story concerns first-time flier astronauts heading toward the launch pad for their
Kind of. They can't just flip through the channels, but unused bandwidth of the Ku-band comm system can be used to uplink realtime video files and video via Internet. It can also be used to uplink video files of movies and television shows for delayed viewing.The
They do. Sometimes studios will make a digital copy available to NASA to upload to the ISS. The crew sometimes watch films while they exercise on the treadmill. For example, this past summer, Paramount made Star Trek: Into Darkness available. It was uploaded to the crew, and then astronaut Chris Cassidy participated in a
I don't think there have been breakdowns, but there have been a few astronauts who reported reaching a bit of an epiphany the first time they saw the Earth from afar. Seeing it as "one Earth" out there made a couple of them question the conflicts and controversies that were going on during the time. I
Laika (Russian: Лайка;[a] c. 1954 – November 3, 1957) was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth. Laika, a stray dog from the streets of Moscow, was selected to be
Let's look at Sir Isaac Newton's First Law of Motion:An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced
First and foremost to be clear: the astronauts don't go to space to be entertained. They are there to work, and they work hard. This doesn't mean they don't get a chance to have fun, but should the perception be that astronauts
We simply don't shower! Oooooooooo.... gross! We do however, take towel baths. During my 5 months onboard the International Space Station (ISS) in 2007, Oleg, Fyodor and I had a small spot in the FGB module set aside for body clean-up. We had a small water container hidden
Before I answer your questions, here are some trivia about ISSIt flies at 4.791 miles per second (7.71 km/s). That's fast enough to go tothe Moon and back in about a day.It has more livable space than a 6-bedroom houseIt has two bathrooms, a gymnasium and a 360-degree bay window.The ISS crews have eaten about 25,000
Saturdays mornings are devoted to cleaning the ISS. Astronaut Clayton Anderson has had first hand experience. See his answer How is the interior cleanliness maintained aboard the International Space Station?Astronauts do have use of a standard vacuum cleaner. (Which is a little ironic considering their proximity to the vacuum of space.) An
They eat much like anyone on earth, with a focus on nutrition and foods that produce less waste through the body, of course, (given that everything that comes out has to be collected and disposed of or recycled). The microgravity environment requires that foods need be solid, with minimum crumbling or particles, and liquids and sauces,
Those of us on the ground like to remove that concern by keeping them busy working. But, the docs say we have to give them some free time.The first thing astronauts usually mention is the simple act of looking out
Astronauts come back home inside the protective confines of a spacecraft, that's how.This isn't an especially easy process since they are traveling at least 17,500 MPH (7.8232 km/second) to stay in Earth orbit.So, first a spacecraft fires retrorockets, which slows
Floating, tethered to the wall of the spacecraft or in a hammock like sleeping bag and requires that astronauts sleep in a crew cabin, a small room about the size of a shower stall. Astronauts have reported having nightmares, dreams, and snoring while
How do astronauts on the ISS keep from floating while working on experiments or using in place equipment?
Astronauts can stay in place by hooking their feet under the blue foot rails around the station. In fact they often observe that the tops of their feet become sore and calloused while the callouses on the bottom of their feet drop off.Astronaut Scott Kelly..."The calluses
It is true that space is more or less a vacuum and sound requires a medium to travel.Sound travels through the air in the form of vibrations and that's how we hear each other on earth. Space has no air for sound to travel.
How do we spit when we brush our teeth? In truth, we have options.If you watched the video that accompanied other folk's answers to this question, you saw one of those options. So ably demonstrated by Canadian Astronaut Chris Hadfield, we
Staying clean takes more work in space. In space, the astronauts do not have a bathroom as we have at home. But, they do have their own toothbrushes, toothpaste, combs, brushes, and shavers. These are kept in a Personal Hygiene
They're not in deep space, but the International Space Station crew is assigned 2 hours 30 minutes of exercise every day (usually in two sessions, 1 hour 15 minutes each) to prevent bone loss and muscle atrophy that take place in the absence of the exercise we naturally get on Earth walking and performing
I'd say its pretty easy to stay healthy in a spacecraft where your meals are controlled, prepared and measured to the milimeter and there's no McDonald's down the street to tempt you. Astronauts eat during their lunch breaks and the rest of their time is spend either carrying out scientific experimentation
The funny thing is that there isn't a sex urge in a microgravity environment. Being in so-called
For a while, the question wasn't how women would menstruate in space but whether it was too risky to find out.Although the first female cosmonaut, Valentina Tereshkova, had flown inVostok 6 in 1963, women were excluded from the U.S. space program during its early years. The official reason for this was that, as a
Astronauts tend to engage in a variety of activities to pass the time. As the other answer on this question states, they do spend quite a bit of time looking down on the Earth and taking breathtaking pictures.Each
"Can"? We don't know. Typically crew members stay for about six months. This March, however, we will launch an astronaut (Scott Kelly) and a cosmonaut (Mikhail Kornienko) that will stay there for a full year. By studying how they react in those second six months, we will gather
How long do you think we have until the ISS is decommissioned? What will astronauts do after this? Where will they go without the space station?
In the future, not only will the demand for astronauts be greater, but there will be an increasing variety of specialties.I have no doubt that we will for example need astronaut construction workers, ship builders, people who do nothing but put stuff together in space,
There are generally six astronauts on the station at a time, currently there are exactly six*:Robert Kimbrough (NASA)Peggy Whitson (NASA)Andre Borisenko (Roskosmos)Thomas Pesquet (ESA)Sergey Ryzhikov (Roskosmos)Oleg Novitskly (Roscosmos)All of these astronauts are members of the Expedition 50 crew, and will return on two separate Soyuz spacecraft on March 4th and April 20th, 2017.*As of February 11th, 2017
Salaries for civilian Astronaut Candidates are based on the Federal Government's General Schedule pay scale for grades GS-12 through GS-13. Each person's grade is determined according to his/her academic achievements and experience. Currently, a GS-12 starts at $65,140 per year and a GS-13 can earn up to $100,701
Not too much! Truthfully, we only get a small "per diem" for our time on the International Space Station (ISS). I believe my bank account had a deposit for about $172.00 US after my 152 days in space! That comes out to about $1.20/day! But when
Not a lot. The crew day is heavily constrained and the astronauts have a never-ending list of tasks to do. The crew gets one and a half hours every morning after they wake up to eat breakfast and do anything else they can fit in that time. They
How will astronauts protect themselves from the high dose of radiation and micro meteors during the long trip (9+ months) to Mars?
Except for solar storms, they can survive the cosmic radiation but with an increased chance of cancer along with other survivable problems. The low gravity will definitely harm them for long trips in space.Schemes for artificial gravity and for radiation shielding run into engineering problems. The best method to solve this problem will come from better propulsion systems so
Physical fitness isn't the problem. It's the education and training. I think a person like me, some-number-of-pounds-overweight-but-i'm-not-telling, would fare just fine, with the exception of the training. There are a lot of emergencies that all crew members have to be ready for. They have to know how to operate
This is a good question and it was a problem engineers treated seriously when women entered space programs. The actual reports are actualy quite funny to read today.The answer, determined by women actually having a menstrual cycle in microgravity, is that the effect is about
You do realize that in high oxygen level environments, like there was present in the Apollo 1 command capsule, leads to extremely easy fires being started. Electrical issues on such a fragile, complex ship full of delicate technology like the ISS could easily lead to damaged electrical components, which could spark and start and oxygen fire. Even though the
Just found out that the ISS (International Space Station) has a speed of 27600km/h. How can an astronaut reach it?
By going to the ISS in a spacecraft that reaches the same speed, which is orbital velocity for that altitude. If the spacecraft you're in is moving at the same speed, then the relative velocity between you and the ISS is zero. And since you're basically in a vacuum, there's no air
NASA's live feed of the International Space Station was suddenly cut after an anomaly appeared in the background of one of the astronauts working, sparking a frenzy online. What do you think it was they did not want us to see?
I've gotten to the point where I don't really care about what others think of me when I answer questions like this one. Most will think I'm just another crackpot, believing in Bigfoot and aliens and the supernatural. Well I don't. Not Bigfoot or spooks.
Astronauts come from many backgrounds, so you have a lot of options. The three most common are engineer, pilot, or medical doctor. But NASA has selected everything from chemists to Navy Seals. Choose a path that you could live with, because you will have to live with it,

Exercise is of paramount importance onboard the ISS. The crew must rigorously exercise in order to stave off muscle and bone loss. They are scheduled for 2.5 hours of exercise each day. Both the US and Russian segments have equipment that allows the crew
Their diet is planned out and monitored by the crew ‘flight surgeons' at Mission Control, in order to ensure that they get the required nutrition in such a way that they stay healthy while still enjoying their food.Scott Parazynski (Scott Parazynski (@AstroDocScott) | Twitter) in his autobiography
The seven day week consists of five and half days schedule for working nominal tasks and a contiguous 1.5 days off. That doesn't necessarily mean the crew do no work during that 1.5 days, just that they aren't scheduled for tasks other than mandatory things
They play games...1. FootballUS astronauts Reid Wiseman and Steve Swanson and German astronaut Alexander Gerst cheer their teams from some 230 miles above Earth aboard the International Space Station.These three men really do prove that World Cup fever travels further than planet Earth.The players show off their out of this world moves as they maneuver without any gravity.

According to the NASA website, the basic requirements are:Bachelor's degree from an accredited institution in engineering, biological science, physical science, computer science or mathematics.Degree must be followed by at least 3 years of related, progressively responsible, professional experience or at least 1,000 pilot-in-command time in jet aircraft. An advanced degree is desirable
What work do astronauts do? They have the coolest job in the world! Or out of this world :)Working in SpaceAstronauts perform many tasks as they orbit Earth. The space station is designed to be a permanent orbiting research facility. Its major purpose is to perform world-class science
What would it be like if an astronaut died aboard the International Space Station?Looking about on the web, I lucked into this article. Here's what NASA plans to do if an astronaut dies in space It links to a
What is the protocol for American astronauts at the International Space Station if a war breaks out with Russia?
On the ground, the United States and Russia might have conflicting interests, but in space, 250 miles above Earth, they get along nicely, mostly. There was some tension after the discovery of the leak in the Soyuz escape vehicle, but that played out in the media of both
What is the speed of the Internet wifi that astronauts can use to connect with their personal gadgets on the ISS?
Slow... and slower! When I returned to the International Space Station (ISS) with the STS-131 Discovery crew in April of 2010, social media had just begun to "take off" (good space reference, huh?!). When I arrived I hoped to do some tweeting from space. I tried to use the internet capability
Do you have what it takes to become an astronaut? Space Astronauts require a superior degree of physical fitness to perform their training and go on space missions. I have noticed that a significant portion of spacewalk training on earth takes place under water in
What should astronauts avoid doing? Do you want the funny answer or the serious answer? Not sure...? Well let me give you a little of both!There are obvious things an astronaut shouldn't do. For example, you shouldn't put your spacewalking boots on the wrong feet. Also,
Most of the work astronauts do is Mission Specific. Their basic duty is to make sure that the station is in top shape, So they clean, check equipment, maintain and repair or replace broken equipment.2. They perform world-class science and research that only the microgravity environment can provide.3.They also
What would happen if an astronaut jumped off the ISS towards Earth?They would move away from the ISS for a little while, then come back towards it.By jumping towards the Earth they will reduce the radius of their orbit, and ever so slightly increase their speed (partially because
What would happen to astronauts if they got detached from the ISS during EVA? Would they fall back to Earth or drift away into space?
Becoming detached from the International Space Station (ISS) during an EVA (spacewalk) is a low probability occurrence. While not likely to happen, since it is possible, astronauts prepare for it. For each and every spacewalk, one of the first --and most critical-- steps occurs before ever departing the station's
The person (either an astronaut, cosmonaut, takionaut, etc) who got disconnected would presumably be tumbling because it would take a reasonable amount of force to break the tether (unless they got unclipped from the tether somehow but I will address that later). Due to how small a person is and how little air molecules there are
All four of the remaining shuttles are retired and on display in four locations on the ground, in the United States. No matter where the astronauts are – at home, taking a woodcarving class, golfing, training, or aboard the ISS – the shuttles remain on the ground. The shuttle was used to
After a 6-9 months long trip to Mars, would the astronauts require assistance when coming down the spacecraft as they need it when they return from the ISS due to the 6 months they spent without gravity?
Well, first, for the trip to Mars and back, they will spend almost 3 years in reduced gravity.Human mission to Mars - Wikipedia
You most certainly can.There's a HAM radio station on the International Space Station that is purposed to allow some of the astronauts to chat with radio/space enthusiasts. So what you'll need is a HAM radio.Please note that in some countries (such as Australia) you require a license to operate a HAM radio.These frequencies may be used:Voice and SSTV Down-link:
Are astronauts allowed to bring personal belongings aboard the ISS? (E.g. family photo, teddy bear, lucky necklace etc.) What are the physical limitations on bringing personal stuff? (by weight and dimensions)
The Space Shuttle program instituted a PPK (Personal Preference Kit) that was used to carry personal belongings of each crew member.The contents of a PPK were limited to 20 separate items, with a total weight of 0.682 kilograms (1.5 pounds). The volume of a PPK must be contained in a 12.82
Well, I don't think it is forbidden, but it doesn't happen. 1. The logistics of such act alone... The station might seem big, but it is actually quite small. Finding place to be alone is challenging. 2. Physics is a heartless bitch. We need gravity for most of our sex moves. You have nothing to hold
NASA astronauts are not allowed to unionize in the sense that you are probably thinking about. As mentioned here, they are either civil servants or officers of the US military. They are not allowed to strike, for instance. However, they have been known to band together at times to get
The word "flying" is defined in my Webster's dictionary as traveling by air, whether applied to aircraft or birds. Hence, we should not refer to "flying in space," because air has no role."Fall," and its dependent grammatical forms, may apply
There has yet to be created a bank in space so all money that an astronaut earns is deposited into their accounts on Earth as if they had never left. In fact the government treats them as if they were on routine travel and receive per diem of around $2 a day. The same amount
Aha, we come to money!If you try reading the posts of real life astronauts on quora, you will find something which most say i.e.
Not sure about ISS, but there have been astronauts who hated their mission.The best example was probably Apollo 7, the first manned Apollo flight (orbital only), in which the astronauts got grumpy and spent a good deal of time arguing with ground control and complaining about the mission plan. At one point after completing an experiment, one
I think the questioner may have been thinking about the shuttle missions to the ISS, which obviously stopped when they retired the fleet.But that doesn't mean that people aren't still going there. There are other ways to get into low earth orbit... OK one other way, the Russians. And they keep
As we know, when something from space falls to earth, it burns. How do astronaut come back to earth?
Astronauts returning after a mission in space usually return in their space vehicles. The two principle factors that ensure a spacecraft can safely re-enteer the earth's atmosphere and head for a safe landing are the shape of the vehicle and its angle of reentry. Let's take the SPACE SHUTTLE as an example. Because it
Assuming they had a space suit with an indefinite supply of water, food, and breathable air, is it possible for an astronaut on a Space walk outside of the International Space Station to float all the way to the moon and stick the landing?
If an astronaut decides to
Can an astronaut survive if he re-enters the atmosphere without a spacecraft and just having a parachute?
Let's put it this way: the remains of the astronauts on Columbia's final mission were not found as bodies that had fallen from the sky wearing spacesuits. According to NASA's report: Loss of Signal: Aeromedical Lessons Learned from the Columbia Mishap, they were found, along with pieces of life support equipment, as hundreds of small fragments
Yes, and ofcourse Astronauts can see other planets from ISS. Since, planets like Venus, Mars, Jupiter can easily be spotted from Earth and in this case, when astronauts are above the Earth's atmosphere (400 Km) and free from atmospheric pollution. It obviously provides a good and clear sighting for Planets and Stars.Here's the picture of Venus seen
Yes. They have freeze-dried coffee in pouches. The pouches are connected to the galley equipment which can send pressurized water at 70 Celsius through the crystals, making coffee.Normally they drink it via the built in straw in the pouch, but astronaut Don Pettit actually invented a cup that works in space.The Canadian donut/coffee shop,
Astronauts most certainly can cast their vote from the International Space Station (ISS). As a matter of fact, I did just that in 2007! And making voting from space even more cool (at least to me anyway) is the fact that my beautiful bride Susan
To make a long answer short, yes, the astronauts on the ISS could see a solar eclipse. But it wouldn't be the same as viewing it from the earth's surface.If you didn't realize, to see an eclipse in totality, you have to be at the right place at the right time. If you were on the earth, you might

Can United States (US) astronauts return to Earth from the International Space Station (ISS) without Russia? Nope... no way, no how. At least not today.The US mothballed their space shuttles... all of them. They are "on blocks" in various museums across the country. Discovery, Atlantis, Endeavor... all of them. Bad move,
Can astronauts see Earth lights from the ISS?Yes, the ISS maintains an orbit with an altitude of 'only' 380 km (+/- 50 km). For comparison: To the Moon it is 384'400 km.So you can clearly see lights in the night. But your picture is not from
If you can see me coming up the road from a mile away, then I can see you coming from a mile away. If this statement is correct, then let's turn your question on it's head, and run an experiment for ourselves, shall we? I have found a few links on the web from
Yes, they can, and do. Some wear it on a necklace rather than on the finger. (I assume in part because of the fluid changes created by micro-gravity.) The only limit to it would be that they can't wear them while in a spacesuit. (Gloves are pressurized. A ring could be damaged, or damage the suit, or even
I'm a little torn about this idea.NASA easily has all the technical information necessary to go back, in terms of orbital mechanics, energy required, spacecraft design needs and launch vehicle requirements. So I'm enthusiastic on America's capability to return to
The answer is yes! And no! There are limits as to how many crew members may sleep on board ISS, as her systems are designed to accommodate a certain number of living, breathing, sweating humans! Pre-flight, the ground control team gave "permissions" as to how many could stay on ISS for sleep
Did the Apollo command modules return to Earth's atmosphere from the Moon fast enough that if there were ejection seats for the astronauts, would three astronauts ejecting have been survivable for them?
Did the Apollo command modules return to Earth's atmosphere from the Moon fast enough that if there were ejection seats for the astronauts, would three astronauts ejecting have been survivable for them?The Apollo command modules hit the atmosphere at 25,000mph (40,000kph). Peak temperatures exceed 5000F (2,800C),
