American Astronauts Mission To Space

Radiation (also known as nuclear radiation) refers to particles or waves emitted by radioactive substance. Nuclear radiation comes from the waves from a nucleus. Ionising radiation can

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

While this is a deeply rooted concern for NASA, the organization plans to make progress in making human space travel safe and productive. In 2016, Former President Barack Obama wrote an article on CNN’s wire service with gargantuan hopes for the future generations of space travel to develop in the future. In the article entitled, “ America Will Take the Giant Leap to Mars”, Obama proposes that the United States will be capable of sending astronauts to Mars by the year 2030. To support his statement, he comments, “I’m excited to announce that we are working with our commercial partners to build new habitats that can sustain and transport astronauts on long-duration missions in deep space”(Obama 1). Here, Obama is acknowledging the fact that astronauts have been, and are, affected by radiation and loss of gravity when exposed to “deep space” for long periods of time. He is also revealing that through years of research and development, the government is prepared to safely send America’s astronauts to other planets for the purpose of exploration and advances in many technological fields. Yes, astronauts’ health

Missions to space pose a great risk on astronauts. Space exploration risks human life. Staying in a spacecraft is not easy, the conditions are harsh, and making the survival during space travel is a challenge. The effects of radiation on the body and bone loss are all a risk that you must take to go and explore in space. According to the website NASA, “The human body is

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

There are two main causes of radiation when travelling in our solar system [3]. One of them are solar flares, which release X-rays and Gamma rays, and the other are CMEs. CMEs release large amounts of X-rays, and these are what are responsible for auroras on Earth. Some solutions to make radiation less of a problem for astronauts is in how structures of space crafts are built to minimize radiation and also the materials with which they are built with [1].

“After all, space is hardly benign: cosmic rays, extreme temperatures, and prolonged desiccation will relentlessly corrode any biology that takes too much time en route,” wrote Shostak.

The session opened with the former director of NASA's Jet Propulsion Lab, Dr. Ed Stone on how space exploration has changed our view of the solar system and continued with discussions by Dr. Margie Kivelson, professor of Space Physics, and her involvement in the study and development of magnetometers in studying the moons of Jupiter with the Galileo spacecraft. Dr. Kevin Hand, the deputy chief scientist for Solar System Exploration at NASA's Jet Propulsion Lab spoke on connecting space exploration to the understanding of life on earth and the search for habitable worlds. Dr. Bethany Ehlmann, a research scientist at NASA's Jet Propulsion Lab, discussed her involvement in the Mars rover program and exploration of habitable worlds. Participants in the audience posed questions on environmental possibilities and consequences, the composition of matter on Earth and the importance of space exploration in terms of human

There are the obvious dangers of outer space: the high-energy radiation, the lack of pressure in the vacuum and the severely low temperatures. These cause an abrupt death when encountered. However, there are other lethal repercussions that can leave a heavy toll on the body with much more gradual yet deleterious symptoms that have the potential to linger long after the trip. Some of these issues are the loss of muscle mass, bone microfractures and the reduction to the immune system. Because these problems cannot be solved by our current technology, astronauts must undergo safety measures that help combat these

Do you ever wonder how radiation was discovered? Or when it was discovered? It all started in 1895, when Wilhelm Roentgen discovered x-rays. Six years later, he was honored with the first Nobel Prize in Physics; by then, doctors were already using primitive x-rays to diagnose illnesses(Men’s Health watch 1). The collaboration between physicians and physicists has continued ever since, resulting in amazing advances far beyond Roentgen’s wildest dreams. Physicists tell us that ionizing radiation delivers energy in the form of photons that pack enough oomph to strip electrons away from the nuclei of atoms(1). We are continuously exposed to tiny amounts of ionizing radiation from cosmic rays and naturally occurring radioactive elements here on earth. We accept this so-called background radiation without blinking an eye, but we

Introduction: Ionizing radiation is a form of radiation that is characterized by displacing electrons from atoms or molecules, forming ions. Some examples

The second source of space radiation is called a Solar Particle Event or SPE. This type of radiation originates from solar ejections of charged particles, usually as X-rays~cite{nasa}. The cause of an SPE is generally attributed to a loss of ideal-MHD (magnetohydrodynamics) or stability within the Sun 's atmosphere~cite{forbes}. Although SPE 's can eject over a billion tons of matter into space, the Earths magnetosphere can deflect most of the charged particles. Outside of the Earths magnetosphere, though, the dosage of an SPE can be lethal in a matter of hours~cite{nasa,smart}. In 1972, when Apollo 17

While most people understand that becoming an Astronaut isn't the simplest career to break into, they probably don't understand the rigorous mental and physical conditioning that is required to prepare an individual's mind and body for space. Beyond the physical strain that is placed on a person's body from the actual flight traveling to space, there is added strain to a body the longer the Astronaut is in space. NASA has recognized the necessity for a program to prepare the Astronauts for their mission to space, in addition to post rehabilitation upon returning to earth.

Astronauts who are in space for long periods of time face many dangers to their physical and mental health. Long periods of weightlessness can weaken bone structures, facilitate loss of muscle mass and dampen the immune response. [1] On top of that, astronauts in space are confined to small enclosed living quarters and have to see the same people everyday. However, NASA, ESA and other organizations have studied these problems and have come up with methods to mitigate these hazards.

Radiation has been an ever present ingredient in the evolution of life on the Earth. It is not something new, invented by the ingenuity of man in the technological age, it has always been there.
