Human Exploration Of Saturn 's Satellite

They are similarities. All have dates and facts. For example in “The Mysteries of Saturn” it states, “in July 2004 the Cassini spacecraft entered Saturn’s orbit and began to collect valuable information” In “Cassini Mission” it states, “in December 2004 a probe was dropped into Titan’s atmosphere. Then the leader began gathering data.” According to the illustration the first picture of Earth, Mars, Venus, and Saturn together was taken by the Cassini in 2013. All of this information was gathered using improved technology.

Underneath the largest rocket in the world, on May 8, starting at 11:00, were sixth graders. The entire sixth grade of South Mckeel Academy slept underneath the Saturn V rocket. Not an experience to forget. Previously, the middle schoolers had taken a brief tour of the Kennedy Space Center Visitor Complex, which houses the space shuttle Atlantis. They would actually get to visit the shops and kiosks on Friday, the day after. Onto the subject of the rocket itself.

Radiation was discovered in 1895 by Wilhelm Roentgen during a scientific experiment. Roentgen, classified radioactivity into three concepts: negative, positive, and electrically neutral. Radiation- is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Technology is created with radiation and humans are exposed to the aspect daily with tons or material; especially in the doctor’s office and everywhere else.

This note is very important, because radiation is a very dangerous thing and you have to make sure you know the steps and for what you’re doing. Never take a risk.

Secondary radiation is developed from any matter being hit by primary radiation. Secondary x-rays have less penetrating energy than primary radiation. Acute (short term) effects of radiation result from high doses of whole body radiation, 100 rads and above. Clinically, a person may experience a mild and transient illness to death. It may occur minutes, hours, or weeks after the exposure. The median lethal whole body dose for humans is 450 rads. Chronic (long-term) effects of radiation can arrive years after the original exposure. It also may have cumulative effects on the somatic cells over the lifetime of the patient. Future generations may experience genetic

Radiation is part of the aftermath of war. In “Thunder in Roses” people everywhere are affected. The author stated “The air is becoming radioactive.” (Sturgeon 191). Only a few million people were left after the war hit them. Most of the bombs that hit the states were nuclear. “So saturated is the atmosphere with Carbon Fourteen

should still be responsible for the people that were exposed to the radiation is because it could spread and accidently cause other to suffer and could help support the people suffering from the radiation. Radiation is energy and it can come from unstable atoms or it can be produced by machines. Radiation travels from its source in the form of energy waves or energized particles. There are actually two kinds of radiation, and one is more energetic than the other. It has so much energy it can knock electrons out of atoms, a process known as ionization. This ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. While there are other, less energetic, types of nonionizing radiation (including radio waves, microwaves—and visible light), this booklet is about ionizing radiation (Baes). According to illinoispoisoncenter, radiation comes from the sun and outer space, from man-made sources such as X-ray machines, and from some radioactive materials in soil. Even though radiation cannot technically spread from person to person, we encounter some radiation from foods, water, the air, our own bodies, and through medical procedures throughout our daily life and never usually receive too much that would cause

They usually cause something specific too. For example, ultraviolet radiation gives people sunburns (if exposed a sufficient amount). X-rays and gamma rays can make people sick or even die. If the dose is not sufficient, then there won’t be explicit effects (called non-ionizing radiation), however it is still dangerous.

Ionizing radiation is a form of radiation that can alter the structure of DNA molecules in living cells. It is a kind of energy produced by atoms that travels in form of electromagnetic waves. Sources of this form of energy are x-ray

The main source of radiation exposure to human life is Radon( 222Rn ) and its progeny which represent nearly 50% of the total human exposure to radiation from natural sources.222Rn is a radioactive gas producing from decay of Radium( 226Ra ) which is found in a wide variety of rocks, soil, natural gas and ground water. Most water sources in the earth’s crust have different levels of Radon concentration depend on the local geological characteristic of the source. Radon gas enters into the human body by inhalation and ingestion of drinking water and eating food, subsequently cause damage to sensitive cells of organs in the body ,such as respiratory and digestion systems.

Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They are not very penetrating so can be stopped by a piece of paper or skin. Beta particles have 1

“When we speak of dangerous radiation exposure, are we speaking of alpha radiation, beta radiation, or gamma radiation?”

Radiation is one of the main forms of energy (Pettigrew 1). In today’s environment we are only familiar with the basic types of radiation. These types are in the form of

Once the mission leaves the Earth’s atmosphere and travels into space, the next challenge awaits. The Earth’s atmosphere and magnetic field act as a shield and deter a large portion space radiation. Space radiation comes from our Sun in the form of solar radiation and also comes from outside our solar system in the form of cosmic rays (Gray, 2013). Radiation may be the most dangerous phenomenon a long duration spaceflight could face. Solar flares erupt from the Sun and send millions of tons of charged particles into space at speeds

Since the historic journey into outer space by Yuri Gagarin, manned spaceflight and space exploration have generated and motivated astounding inventions and innovations. These discoveries and developments affect every single person on Earth, and have improved a wide range of fields including health, food, technology, entertainment, automobile, dental, medical, safety, sports, and many more industries.
