Alpha: How will we maintain pressure and keep the air from leaking out of the lunar hab?

To retain atmosphere and pressure, the lunar hab can be interwoven with layers of Kevlar and Mylar around an air bladder, also Vectran (a liquid crystal poylmer) would
needed because it is very strong, durable, and can withstand very cold temperatures. The inflatable habitat is pressurized and capable of allowing astronauts to live on the moon. It is also built to mantain the atmosphere inside. There are two models of the lunar habitat that NASA has built. Inflatable and expandable (collapsible) models are available to the NASA program. The inflatable model is the most favorable because it is made of lightweight materials and it optimizes living space. Because it is inflatable and made of lightweight material, it will be easy to move around with. Plus you can deflate it to conserve storage space.
To live in space, we need oxygen. So what do we need to produce oxygen? The answer is simple, plants. This is the photosynthesis cycle hotosynthesis is an important cycle that produces the most important gas on Earth, oxygen. It also uses carbon dioxide, a gas that when breathing in too much, is poisonous to humans, to produce oxygen. The photosynthesis cycle is made up of three steps. First, light energy is converted into chemical energy to be stored within plants. Second, it transforms carbon dioxide into a solid form, a very important component in all living matter. Lastly, the plant uses the carbon dioxide it has stored to produce oxygen as an important by-product. To get in and out of the hab we will have to make a room that can be used as a air lock we will have to make some designs of it.

Notes:

How do you get in and out of the hab without letting out the air in an inflatable hab? Can you put some pictures of NASA's model habs on the page? What are these models made of? What about insulation against the temp extreme

The model on top isn't a inflatable but is an good example of an air lock. the model and the bottom is made of pillow like cubes that can be connected and then
covered with a concrete that can be made from some of the materials that can be found on the moon plus water. For the heat insulation we will use the stuff they use for houses!

How much air can we take?

NASA has been developing regenerative life support systems. These systems use plants or algae along with physical and chemical processes. The green plants produce food; convert carbon dioxide to oxygen through photosynthesis

We could possibly bring some plants up into space and we would use as much air as we can, and then we could use the plants to produce more air as well, and we would not need to bring up as much weight and we would not have to pay so much.

70% and 80% of the air that we breathe on earth is made of marine plants. Mostly the plants that provide our air on earth is alage. Our earth holds three times as much of water than on land, witch shows that marine plants produces more air than plants on earth













It is estimated that between 70% and 80% of the oxygen in the atmosphere is made by marine plants. Because so many species of marine plant life are technically algae, that makes algae the plant singly responsible for making most of the air we breathe. The earth holds almost three times as much water than land, so it shows to reason that marine plant life produces much more oxygen than land plants. Ocean plants may be hard to see becuse they are usually found deep underwater, but they are needed for our atmosphere.Aquatic plants are plants that have adapted to living in water (saltwater or freshwater). Marine plants can only grow in water or in soil that is permanently filled with water. So we could take the plants up and use them as one of our air supplies. Aquatic vascular plants can be ferns or angiosperms. Seaweeds are not vascular plants; rather they are multicellular marine algae, and therefore are not included through aquatic plants. As opposed to plant types such as mesophytes and xerophytes, hydrophytes do not have a problem retaining water, due to the abundance of water in their environment. This means that aquatic plants have less need to regulate transpiration, which would require more energy and be of little benefit to the plant.
