SPACE EDUCATORS' HANDBOOK Spacesuits for the space shuttle era are pressurized at 4.3 pounds per square inch (psi), but because the gas in the suit is 100 percent oxygen instead of 20 percent, the person in a spacesuit actually has more oxygen to breathe than is available at an altitude of 10,000 feet or even at sea level without the spacesuit.

How is oxygen made aboard a spacecraft? The system is called the solid fuel oxygen generator (SFOG) and is located in the station's service module (Zvezda). The SFOG, which is also called oxygen candles or chlorate candles, has canisters that contain a mixture of powdered sodium chlorate (NaClO3) and iron (Fe) powder.

- • Physical state of the chemical contaminant. The highest level of skin protection is afforded with a fully-encapsulated suit. This type of suit is impermeable to gases and vapors and protects all parts of the body (hands, arms, head, face, torso, legs, etc.). A fully-encapsulated suit looks like a space suit.

How long would it take for a human being to freeze solid in outer space? 1 So, it was possible for astronaut David Bowman in 2001: A Space Odyssey to survive when he ejected from the space pod into the airlock without a space helmet and repressurized the airlock within 30 seconds.2  Your tissues (skin, heart, other internal organs) would expand because of the boiling fluids. This process could take from 30 seconds to 1 minute. 2  So, it was possible for astronaut David Bowman in 2001: A Space Odyssey to survive when he ejected from the space pod into the airlock without a space helmet and repressurized the airlock within 30 seconds.

Venturi mask For 40% the ratio decreases to 3:1. Since the jets in venturi masks generally limit oxygen flow at 12 to 15 liters per minute the total flow decreases as the ratio decreases. At an oxygen flow rate of 12 liters per minute and a 30% FiO2 setting, the total flow would be 108 L/min. At a 40% FiO2 setting, the total flow would decrease to 48 L/min.

OXYGEN IN MARS' ATMOSPHERE - we can live on mars (breathable air) Mars gravity is unable to hold on to gasses on Mars. Most if not all Gasses will scape into space from Mars gravity. Therefore, No matter how much OXYGEN you put into MARS atmospher, it will scape from Mars. Unless you want to make space a breathable place for Human. Just Kidding. I Have read many articles and plans about how to transforms Mars to living place.

- Spacesuits are inflated like balloons to create pressure on the body equal to the Earth’s atmospheric pressure. In addition, in the hours before a space walk, astronauts breathe pure oxygen to reduce the amount of nitrogen in their blood.

What happens to the unprotected human body in space? If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

- The percentage of oxygen in the atmosphere doesn't appreciably change with altitude. There's about 23% oxygen in the air at sea level, and about 23% oxygen in the air at the top of Mt. Everest. So the 'content' is the same.

How much does NASA pay per kg for hydrogen and oxygen in rocket fuel? Total amounts for those interested: 384,071 gallons of liquid hydrogen in the external tank of the shuttle, for a cost of $376,389.58. ~141,750 gallons of liquid oxygen for a cost of $94,972.50. The total cost of all propellant for rocket fuel is $1,380,000.

How many molecules of oxygen do breathe in in one breath? How many molecules of oxygen do breathe in in one breath? The average pair of human lungs can hold about 6 liters of air, but during normal respiration, only about 500 mL (one half of a liter) is inspired. Oxygen makes up 21% of air. There are 2.7 x 1019 (2,751.3) molecules in every cubic centimeter of air. 0.5 liter (500 cubic centimeter) contains 1,375,650 molecules, 21% of which are 288,886.5 oxygen molecules. (see Composition of Air)

- After donning their spacesuits–not a trivial process, since these suits weigh up to 136 kg (300 lbs) on Earth – they spend an additional 60 minutes breathing pure oxygen. After final checks for suit leaks the remaining air in the Crewlock–about 34,500 Pa – is vented to space.

Deep diving An atmospheric diving suit allows very deep dives of up to 700 metres (2,300 ft). These suits are capable of withstanding the pressure at great depth permitting the diver to remain at normal atmospheric pressure.

Oxygen Oxygen gas is the second most common component of the Earth's atmosphere, taking up 20.8% of its volume and 23.1% of its mass (some 10 15 tonnes). Earth is unusual among the planets of the Solar System in having such a high concentration of oxygen gas in its atmosphere: Mars (with 0.1% O 2 by volume) and Venus have much less. The O

How much did the Space Shuttle weigh? The external tank held 143,000 gallons of liquid oxygen (1,359,000 pounds) and 383,000 gallons of liquid hydrogen (226,000 pounds). The fuel weighed almost 20 times more than the Shuttle. At launch, the Shuttle, external tank, solid rocket boosters and all the fuel combined had a total weight of 4.4 million pounds. The Shuttle could also carry a 65,000 payload.

- The primary source of oxygen will be water electrolysis, followed by O2 in a pressurized storage tank, said Jay Perry, an aerospace engineer at NASA's Marshall Space Flight Center working on the Environmental Control and Life Support Systems (ECLSS) project.

Is there oxygen on Mars? MARS' ATMOSPHERE IS MADE OF 95.32%. JUST 0.13% is breathable oxagen-well, not breathable hence humans need at least 21% of oxagen to breath (21% of the earths atmosphere is made up of oxagen, and clearly, life IS possible.

- The oxygen content of the Martian atmosphere is only 0.13 percent, compared with 21 percent in Earth's atmosphere. Carbon dioxide makes up 95.3 percent of the gas in the atmosphere of Mars. It also contains nitrogen and argon and very small amounts of water and methane.

How is oxygen made aboard a spacecraft? Most spacecraft carry their own supply of oxygen with them and may have one backup system. However, the missions of these spacecraft last a short time, on the order of days to two weeks. In contrast, the International Space Station (ISS) was designed for long-term spaceflight and has been in orbit since 1998.

- At 500 psi with a flow rate of 6 liters per min, there are 28 minutes of oxygen left. Yes, there is enough for the trip. The service capacity for an e-cylinder carrying oxygen is 1900 psi. The volume of oxygen in an e-cylinder is 660 liters.

How Much Breathable Oxygen Gas Is There In The Atmosphere? From another perspective, though, the earth is chock full of oxygen. For example, nearly half the earth’s crust–forty-six percent–is oxygen! It’s just not in a free state, so you can’t breathe it.

Spacesuit The Apollo missions utilized more complicated suits that solved some of these problems. For moon walks, the astronauts wore a seven layer garment with a life-support backpack. The total weight was about 57 lb (26 kg). For the Space Shuttle missions, NASA introduced the Extravehicular Mobility Unit (EMU).

Ocean Dead Zones Likely To Expand: Increasing Carbon Dioxide And Decreasing Oxygen Make It Harder For Deep-sea Animals To Breathe Brewer and Peltzer's calculations suggest that the partial pressure of carbon dioxide will increase even faster in the deep oxygen minimum zones, with pCO2 increasing by 2.5 times, from 1,000 to about 2,500 micro-atmospheres.

- (PhysOrg.com) -- In a flyby past Rhea, Saturn's second-largest moon, NASA's spacecraft Cassini has revealed the presence of a thin atmosphere of 70 percent oxygen and 30 percent carbon dioxide, which is apparently sustained by chemical decomposition of the moons ice-covered surface.

Cabin pressurization At this altitude, there is about 25% less oxygen than there is at sea level. Hypoxia may be addressed by the administration of supplemental oxygen, either through an oxygen mask or through a nasal cannula. Without pressurization, sufficient oxygen can be delivered up to an altitude of about 40,000 feet (12,000 m).

- How long does oxygen last in the spacesuit? The space suit, called the Extravehicular Mobility Unit or EMU, uses 100 percent oxygen instead of air. When a crewmember does a spacewalk, the suit is pressurized to about 1/3 of atmospheric pressure. The amount of oxygen contained in air at this pressure is not adequate, thus requiring the use of pure oxygen.
