Astronauts cannot sleep in space due to several factors. Firstly, sleeping in zero-gravity environments can be quite uncomfortable, as the body is not held in a fixed position, meaning there is no pressure on individual parts of the body like the back and legs which we rely on to achieve a comfortable sleeping position.
Additionally, the sleeping environment on board space missions is very different to what humans experience on Earth. Noise levels are a lot higher due to the various pieces of machinery on board, and astronauts need to wear helmets for safety reasons, making it difficult to move and get comfortable.
Furthermore, there is no night and day cycle in space, which can disrupt sleep patterns, and bright lighting on board further affects our body’s natural sleep rhythms.
In spite of these factors, astronauts still need to find ways of getting good quality sleep on space missions. Therefore they often wear comfortable, specially-designed sleep suits which fit snugly to help create a feeling of pressure and security.
Alternatively, they may wear masks and earplugs in order to block out sounds and lights, helping to induce a more calming sleep environment.

Can you drink alcohol in space?
No, it is not recommended to drink alcohol in space due to potential health risks for astronauts. Alcohol does not mix well with the already limited amount of oxygen in a space environment. Additionally, it can be difficult for astronauts to process the effects of alcohol in the unique environment of space since the body’s ability to process alcohol is dependent on having the normal amount of gravity.
In addition to these physiological risks, alcohol may have negative impacts on decision-making processes, causing too much risk of error with regards to mission objectives. As a result, NASA and other space agencies do not provide or allow alcohol in space.
How much do astronauts get paid?
Astronauts are paid based on their rank and years of experience in the military, if they come from a military background. Astronauts also receive a variety of allowances, which vary from mission to mission.
Astronauts who work for NASA are assigned to the Astronaut Group, which typically includes individuals in mid-career positions. The starting salary for an Astronaut Group member is $64,724 per year. With annual increases for experience and additional training, an Astronaut Group member can expect to make up to $141,715 per year.
Astronauts who serve as mission specialists generally make more than Crew Commanders and Pilots. Mission specialists typically receive a pay of $66,026 to $144,566 per year. Commander and pilot salaries range from $80,970 to $141,715 per year.
Astronauts who serve on international missions typically receive extra compensation.
In addition to salaries, astronauts receive a variety of other benefits, including a housing allowance and flight insurance. An astronaut may be eligible to receive a special allowance for each day of space travel and a hazard pay allowance for some missions.
Other benefits may include access to specialized medical care and dental insurance.
What is the temperature inside the space station?
The temperature inside the International Space Station (ISS) is typically kept at a comfortable range of 20 to 26° Celsius (68 to 78. 8° Fahrenheit). However, the temperature can fluctuate slightly depending on a variety of factors such as daylight, activity on the station, the onboard equipment, and the station’s orientation to the sun.
In addition, the temperature may change during spacewalks when the hatch is opened. Astronauts also have access to environmental control units that allow them to adjust the temperature as needed.
What do astronauts do in their free time?
Astronauts have a few spare moments to spend in their free time while in space. Some of the leisure activities vary depending on the individual astronauts but can include things like reading, sleeping, physical activities such as exercise, listening to music, playing video games, watching movies, communicating with their family and friends, and even gardening.
They can also communicate with mission control and other crew members, often taking the opportunity to use their free time to discuss the goals of a mission, discuss mission-specific topics, or learn more about their research projects.
Astronauts often make use of the cupola for observation of Earth, stars, and other astronomical phenomena, and take pictures of the same for public release. Astronauts might also take the opportunity to conduct maintenance tasks and experiments in their spare time.
How many bodies are lost in space?
It is difficult to estimate exactly how many bodies have been lost in space, as space is such a vast and largely unexplored area. However, a conservative estimate suggests that over the years at least 500 astronauts, cosmonauts, and pieces of space debris have been lost in space.
It is known that more than 400 astronauts/cosmonauts have attempted spaceflight as of 2017 and more than two dozen have died in space since the very first spaceflight in 1961. These cases include those whose spacecrafts have malfunctioned and they were lost in the vast vacuum, explosions in mission launches and soilings of Earth’s orbit, and even a number of tragic accidents during their landing on their homeland.
As of 2014, the total number of casualties during the spaceflight program across different countries was estimated to be around 101. Consequently, it is safe to assume that hundreds of bodies and pieces of debris have been lost in space over time.
Would a body ever decompose in space?
Yes, a human body would eventually decompose in space due to the vacuum and radiation it would be exposed to. Without the oxygen, warmth and moisture necessary to sustain life, a body exposed to the harsh environment of space would eventually mummify and decompose, eventually becoming nothing more than a skeleton.
The decomposing process would be slightly different than it is on Earth, though, due to the lack of oxygen and weak gravitational force. Out in space, a body would likely decompose at an accelerated rate due to the chills and lack of air pressure, even when compared to the same environment that exists on Earth.
In this case, the body could become unrecognizable in as little as 12 weeks, whereas in an enclosed environment with proper conditions, it could take a period of years for a body to completely decompose.
What does space smell like?
Space has no smell as such, although it does have a certain emptiness associated with it. Astronauts have reported that there is an odd smell or taste in the air after a spacewalk. It has been described as a combination of gunpowder, searing steaks, and raspberries.
The distinctive smell is caused by the release of chemicals in a confined space due to the presence of oxygen and other substances. The smell is not the same all the time; astronauts report different smells depending on their activities at the time.
Additionally, the smell can vary based on the location, as there are different concentrations of gases and particles in different parts of space. Some astronauts describe the smell as metallic, while others characterize it as sweet, smoky, fishy, or even like a barbecue.
Do you age in space?
The short answer to this question is technically yes, but not in the same way that we age on earth. Aging in space is due to the relative passing of time, however, the effects of aging are different than what we experience on earth.
Due to the lack of gravity, astronauts’ bodies can experience physical changes, such as bones and muscles weakening, balance and coordination becoming impaired, and vision issues due to changes in blood pressure.
These effects are caused by the lack of activity in a zero-gravity environment, as well as radiation exposure from outside sources in space. In addition, psychologically, being in space for long periods can take a toll on an individual, in the form of loneliness and isolation, which can have a similar effect to aging as seen on earth.
Despite these effects, however, recent research has found that astronauts are actually exposed to fewer aging related stressors than those experienced by astronauts on earth. As such, even though time still passes for those in space, its effects may be much less than what is seen here on earth.
What is the longest period an astronaut has spent in space?
The longest period any astronaut has spent in space is 437 days over four missions, by cosmonaut Valery Polyakov. He spent a total of 678 cumulative days in space, which was a record that stood for 22 years.
On January 8, 1994, Valery lifted off on his 437-day mission aboard the Russian space station Mir, on the Soyuz TM-18 spacecraft. Landing on March 22, 1995, Polyakov broke the previous long-duration spaceflight record of Juston Manber who spent 211 consecutive days in space.
After the fourth mission, Polyakov returned to Earth on August 28, 1999, breaking his own world record and achieving 678 cumulative days in space. It is worth noting that this record was within the guidelines of NASA astronaut Scott Kelly who, in 2016, accomplished 520 consecutive days in space, however, it was without a single break during the period.
Why do astronauts have to be short?
Astronauts have to be short in order to fit within the physical confines of a space shuttle or capsule. Space shuttles and capsules are designed to maximize efficiency and cargo capacity while still safely transporting personnel to and from space.
In an effort to provide the most optimal efficiency and safety, these vehicles are designed with a limited amount of space, which generally cannot accommodate astronauts of taller stature.
In addition to the physical confinement of the vehicles, the advantages of being short for astronauts in space must also be considered. Being short allows more maneuverability and use of living and work space.
Lower body height is also empirically advantageous for astronauts as it reduces their exposure to radiation and decreases their risk of radiation-induced cancer.
Shorter astronauts have smaller force and torque angles to their movements, which could be advantageous in space operations and ground-based exercises. Furthermore, shorter astronauts require less space on the flight deck within a shuttle and they experience less G-Force on launch, a criteria of utmost importance in terms of reducing health risks.
All of these reasons demonstrate why astronauts must be short, for the safety and efficiency of space mission.
Can astronauts have tattoos?
Yes, astronauts can have tattoos. However, the majority of space agencies have policies in place that limit the visibility of tattoos. For example, the United States National Aeronautics and Space Administration (NASA) has a dress code that dictates astronauts must not display tattoos or body art that is visible when wearing their spacesuits.
Additionally, tattoo policies employed by other space programs may limit the locations and amount of tattoos that can be visible.
NASA does not have any specific efforts in place that seek to ban all tattoos, and its regulations stipulate that astronauts with visible tattoos can wear a cover-up if available. However, any body art that is seen as offensive in any way is not allowed, according to their policies.
Ultimately, space agencies strive to maintain an atmosphere of professionalism and a focus on safety, which means that tattoos have to meet certain uniform regulations in order to be allowed. Still, astronauts are allowed to have tattoos and many choose to do so.
