On Mars there is a lot of radiation exposure that for us can cause many health wise risks. We need to figure out a way to stop from all the radiation to take a toll on us. Once, oxygen, radiation and cold temperatures are solved we can now think of the necessities that us humans will need to have in order to survive, like medicine, food and water. But unless we figure out a way to solve these three great factors we will not be able to set a foot on
Primary among these functions is to assist the heart in pumping blood throughout the entire body. The force of gravity ensures that blood is flowing to the lower extremities. In a zero gravity atmosphere, the heart still pumps the excess blood that will no longer reach the legs and can cause an inflated look of a person’s upper torso and face. This effect may cause “space sickness” in humans, which causes headaches and nausea. These effects usually cease once the body adapts to the changes.
The amount of air pressure depends on how often these particles collide. For a balloon to fly, the air pressure needs to be high, at least as high as the outside air pressure otherwise it would crush it. There are a few ways to increase air pressure including adding more gas particles to increase the frequency of collisions or raising the temperature of the air to speed up the particles which in turn would result in more collisions and greater air pressure. Since it is important that the air is heated up, it also helps if the outside air is cooler so that there does not have to be as many gas particles to create the same high air pressure. Overall, buoyancy and air pressure
The sun radiates solar energy towards earth. Some of this energy gets absorbed by the earth’s surface and some energy is radiated back into space as long wave energy. Certain gases in the atmosphere prevent this reflected energy to pass; they trap the energy and thereby warm the atmosphere and the surface of the earth just like in a greenhouse. Therefore, those gases are known as greenhouse gases (GHG). The main GHGs within the atmosphere are Carbon dioxide (CO2) and water vapor (H2O).
Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. Volcanic eruptions - When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world.
Some of the radiation are absorbed, reflected or scattered, while the rest reaches the surface and warms the land and the oceans. Because the earth’s surface is cooler than the sun, the earth emits long-wave, largely infra red, terrestrial radiation back to the atmosphere where much is absorbed by greenhouse gases since these gases are more efficient in trapping long wave radiation. Some of the greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, chloro-fluoro carbons and ozone. When these gases in the atmosphere absorb terrestrial radiation, they warm, but eventually they radiate this energy away. Some of this long wave terrestrial radiation travels upward, where it may be reabsorbed by other gas molecules.
Even if the report is overestimated, the public are well out of harm’s way. Electronics: The field of electronics and computers have also benefited from the space exploration. The astronauts have manufactured miniature electronic parts that could only be produced in the space during their experiments in the space stations and space shuttles. The innovations that they made are now seen here on earth. For example, Apollo technology has been used to produce a lighter breathing system for firefighters.
It would change our climate, but it would not bring us close to the level of uninhabitable Venus. A doubling in CO2 levels would make agriculture much more difficult due to shifts in climate that occur as a result of increasing temperature. CO2 can indeed cause a significant degree of warming if it is suddenly released into the atmosphere, as we have been doing for the past 150 years. Aside from that, increasing temperature can also cause the rising of sea level as the glaciers are going to melt at a faster rate like never before. Next, is the change in environmental health.
Gas or its inability to escape is what causes volcanos to become violent. The longer gas is trapped, the more pressure builds up. The cause of gas building up is the result of the viscosity of the magma the gas is trapped in. Viscosity is the measure of the flow or how easily a liquid flows. If a liquid is viscous it is thick and will flow slowly like honey whereas a liquid that is nonviscous will flow like water.
The Green House Effects is one of the main causes of this warming. Some greenhouse gases are needed. “The greenhouse effect is unquestionably real and helps to regulate the temperature of our planet.” (EPA) Without the GreenHouse effect the Earth could not be warmed. Human activity is adding more of these gases. “The increase in the mean temperature of the earth due to excessive emissions of greenhouse gases such as carbon dioxide, methane, and nitrogen.” ( Green) These extra gases are making it hard for heat to escape the Earth’s atmosphere resulting in warmer temperatures.
