The document discusses cryosleeping by placing human bodies in liquid nitrogen to decrease their temperature and metabolism. Key points include: - Cells are vitrified through the addition of cryoprotectants to prevent ice formation and cell damage during cooling and storage. - Breathing, heart rate, and metabolism all slow greatly when in cryosleep. - The body would be surrounded by liquid nitrogen with tubes providing oxygen and removing carbon dioxide from the head area. - Drugs would induce and reverse sleep/cryosleep states. Nutrients would be provided through TPN during storage. Insulation like expanded polystyrene would surround and protect the storage capsule. A light system would regulate sleep cycles. Alumin

2. Place the human bodies into a container full of liquid nitrogen to keep their bodies’ temperature (core) close to -200
Celsius. - Decreasing body temperature to 32 degrees Celsius. = Decreasing metabolism, heart rate, and body’s
energy as a whole. (as if in mild hypothermia). Heart rate: Normal heart rate would be in between 60 to 100 bpm. At
the same time, sleeping the heart rate decreases to the range between 40 to 80 bpm. Metabolism: An average man
has a BMR of around 7,100 kJ per day, while an average woman has a BMR of about 5,900 kJ per day. It is believed
that during normal sleep, the metabolic rate reduces by around 15%. Our cells are filled with water (liquid); if it
freezes, it would expand & form crystals which would damage the human body. THE SOLUTION TO THAT IS: ALCOR
foundation expressed using vitrification process, which adds to the water in the cells an anti-freezing agent
(cryoprotectants) so when the tissues are cooled to cryogenic temperatures it doesn’t crystallize into ice. ‘We add
chemicals called cryoprotectants to water that can prevent water molecules from gathering together to form ice’.
Instead of freezing, molecules move slower and slower as they are cooled. Finally, at temperatures below -100° C,
molecules become locked in place, and a solid is formed. Water that becomes solid without freezing is said to be
“vitrified”. So basically, there is no damage to cells during cooling because no ice is formed. Finally, cells are
vitrified and biological time is stopped. Because no ice is formed, vitrification can solidify tissue without structural
damage. This new glass form prevents the section from bursting.
•Breathing slows down. The average respiration rate for an adult at rest is 12 to 20 breaths per minute. Normal pulse
oximeter readings usually range from 95 to 100 %. Values under 90 %are considered low. While sleeping the costs
and rate drops below around 88 %.
•Organs need less oxygen to function.
•Decreasing the need for food, energy, and nutrients.

The body will be surrounded with liquid nitrogen from all sides except the
head. The human body needs oxygen to function the whole body system and
produces carbon dioxide. Unfortunately, these chemical substances have got
severe bad chemical reactions (with liquid nitrogen). To avoid harming the
human body with these chemical reactions, there would be a device that would
contain two pipes and will be attached close to the nose and mouth
(the respiratory system organs) of the chosen astronaut. One pipe will be
responsible for giving the right amount and percentage of oxygen that
would perfectly suit the human body selected. The second pipe pulls out
(inhales) the produced carbon dioxide given from the human body. The
device would be fully programmed to open with a timer that assures that
there is no oxygen left to pull out with the carbon dioxide and vice versa.
(The timer would be programmed based on the precise given HEALTH
data and info that would be given for the chosen astronaut), at this
point, it would permit the second pipe to function and vice versa.
2 BREATHING MECHANISM
Here we want to use a drug that makes the astronomer sleep and then an
anti to make him wake up, so after a lot of searches and comparing we
choose a chemical called (PROPFOL) to make him sleep as it is the best
general anaesthetic. The maximum dosage of propofol for adult setting should
not exceed 100 to 200 mcg/kg/min. As we want to wake him as fast as we can
so we choose (RITALIN) as in a study published in sep.20 sowed that it could
bring them out of anaesthesia almost immediately. For adults, the usual dose is
20 to 30 mg (2-3 tablets) each day, but some people may need more or less than
that. Do not exceed the recommended dose. The maximum dose is
60 mg (6 tablets) each day.

4. TPNis comprised of proteins, carbohydrates, fats and various water- and fat-soluble
vitamins, as well as electrolytes, essential fatty acids and trace elements, such
as zinc and copper. Your body needs them all to work properly.
DesignTPN infusions must stay refrigerated, and they’re delivered through a special IV
catheter placed either in your chest or arm. Typically, the fluid bag hangs from an IV
pole next to your bed. Backpacks are also provided (to hold the infusion pump and
TPN bag) so that patients can be mobile while infusing, especially if they infuse
during the day.
AmountYour small intestine’s absorption ability determines the fluid amount you’ll
need. Some patients need two liters of fluid nightly while others need only a
liter three to four nights a week.
Side effects. Mouth sores
. Poor night vision
. Skin changes
• These are not side effects of TPN but are possible signs
of malnutrition or vitamin deficiency that may result
from it.
Progress rate
As we used the cryogenics type of freezing for the body then our rate of
consuming nutrients will massively decrease.

5. Expanded Polystyrene insulation [ EPS ]
● EPS has been chosen to be used as an insulation material around the capsule to decrease the penetration of heat in or out of the
capsule—a slide structure based on a thesis defense, which you can adapt to your needs. EPS Is commonly used in a variety of
applications because of its features of lightweight, good thermal insulation, moisture resistance, durability, acoustic absorption and low
thermal conductivity. It has been increasingly used in building constructions as the core material of structural insulated panels (SIP).
Some of those structures during their service life may be subjected to dynamic loads such as accidental or hostile explosion loads and
windborne debris impacts.
● Advantages
i. it has enough capacity to buffer the impact of the outside world and by changing the shape, good anti-impact ability because 98% of
foam insulation board space is filled with air.
ii. Low water absorption. Studies have shown that humidity will affect the thermal and mechanical properties ; low water absorption
materials help to maintain these properties.
● Disadvantages
i. Flammable, toxic, ordinary polystyrene foam insulation board is easy to burn, toxic combustion fumes, even after the combustion of
flame retardant, it can only reach B. The external wall insulation fire, polystyrene foam insulation board, accounted for 95%.
ii. Polystyrene foam insulation board because of its limited strength, loadbearing ability, tiles need to strengthen treatment.
iii. Polystyrene foam insulation board quality is not stable, because materials factory need to place for a while, after a period of maturity
before they can be used, if not thoroughly cooked, the quality will not be guaranteed, resulting in foam shrinkage cracking.
● Most dangerous Disadvantages when it is exposed to UV, that is prevalent in the space, its reaction is changed as follows:
i. Fading and/or discoloration typically occurs within 2-4 weeks depending on exposure rates. This does not impact physical
performance properties in any way.
ii. Dusting results in a thin layer covering the surface which can deteriorate the outermost cell structure of the polystyrene. This does
not impact the integrity of the overall material.
iii. __Over extended periods of time, when the outermost cells experience ongoing deterioration, the material thickness can erode to a point
________________________ where R-value loss is possible due to the proportional reduction in insulation thickness.

6. Light systemWe know that the day in space is only 90 minutes, so the crew can’t receive the
amount of sunlight that is imposed to prevent producing of melatonin,
[the enzyme which controls our sleep and wake up]. So, the blue colour is an
effective solution to reset our circadian rhythm. Because the blue light plays a
significant rule in blocking the melatonin. So, the crew must receive a high
amount of blue light all day by wearing blue glasses to allow the blue colour to
enter their body and putting a blue screen on laptops and phones. That will help
them stop producing the melatonin all day, make them awake, and increase sleep
quality at night. But 3 hours before bed, they must expose to zero phone screen, zero computer work,
any of that sometimes that’s not realistic. So, they will reduce the blue light exposure by wearing blue light
blocking glasses and use blue light filters on the computer screen like Flux application.
In the process of waking up, we will put a blue light in the capsule, which can allow
the body to stop producing the melatonin.
Benefits . Helps regulate sleep cycles . Improves quality of sleep
Aluminium alloys: it is one of the popular materials in the industrial processes.
Aluminium is rarely used in its pure state. It’s well known as a lightweight
material (it weighs about one-third as much as steel or copper) but Aluminum and
its alloys are also easy to cast, forge, machine, roll and extrude. Magnesium is a
popular choice for alloying with aluminium because the combination typically
creates a material that is moderate to high-strength, weldable and corrosion-
resistant. It has also high ability to resist against radiation.
It can be used to help treat several sleep disorders, including
jet lag, non-24-hour sleep/wake disorder.
