My sci-fi paper will follow the unfortunate events surrounding a spaceship and its crew on the far rim of the galaxy. It will feature the events that unfold after the spacecraft comes into contact with a hypervelocity star (HVS). An HVS is defined as a star that is traveling faster than the escape velocity of the galaxy. In addition, the spacecraft will use a quantum vacuum plasma thruster (Q-thruster) as its propulsion system as described by Dr. Harold White 's research at NASA.
As humans reach out further into space, the realities associated with astronomical dangers emerge. Obvious dangers such as lack of oxygen or extreme temperatures can be relatively easy to overcome, while the subtle and less understood dangers require special

The Van Allen belts consist of an inner and more concentrated belt of protons at a distance of 3,600 km and an outer and less concentrated belt of electrons at a distance of 10,000 km~cite{wilson}. In the most intense regions of the inner belt, exposure can be lethal after a few tens of hours~cite{smart}. This created uncertainty at NASA for whether or not humans could ever travel to the Moon and beyond. In response, the scientist who discovered the Van Allen belts, James Van Allen, proposed a controversial method of removing the trapped radiation. He suggested that a nuclear detonation in space might cause the trapped protons to escape from the Earth 's magnetic field. The theory was never directly tested, but a similar test that detonated a 1.4 megaton bomb in the atmosphere showed that in fact more radiation was added as a result~cite{popsci}.
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
The Van Allen Radiation belt would have been too strong for the astronauts to pass at the time the first moon landing occurred. The Van Allen Radiation belt is a doughnut region in space in which the Earth’s magnetic field traps a high amount of protons and electrons carrying a high amount of energy. Conspirators believe that it would have been impossible for the Apollo astronauts to pass through the Van Allen Radiation belts because the radiation would be too strong for astronauts to pass through the time the first moon landing occurred (Millis). NASA claims, “the Apollo astronauts passed through the Van Allen belts too quickly to be exposed to dangerous levels of radiation” (Griggs). Also, NASA proves, “the radiation would be about 2,500 rem per year with almost no shielding. Considering how quickly the astronauts passed through the belts, they only would have been exposed to about 0.05 rem during the trip there and back” (Millis). Although the radiation levels were safe to pass through, it is proven that the U.S. did not have the right technology and proper shielding at the time to keep the astronaut’s safe while passing the belt allowing American’s to believe the moon landing was a hoax (Griggs).
On the other hand, the geomagnetic storms have been intensified and enhanced in their frequency as magnetic fields of coronal mass ejections indulges with that of the earth that causes change of direction and leave more radiation and magnetic energy into the environment of the planet earth.

This activity is about the main events in New Horizon’s journey to Pluto and beyond.
Along with the technological advances and new theories of the last century, humans have developed a need to explore beyond the known of the final frontier. This resource of knowledge has led to superstitions and concerns about what could happen if people pursue this want of space exploration. Among these concerns are national finances, the world’s health, and ethical standpoints of what really could be waiting on the other side for those who dare venture into the unknown.

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.
In the end, there are a myriad of problems that face space exploration. Some of them are small
The only other places radiation can come from are from the top and bottom of the vacuum chamber. Regardless of how much radiation will be coming from the bottom of the chamber it will not affect us because we won’t be looking under the chamber or above the chamber most likely when the reactor is running.
The Titanic is one of the most famous ships known around the world as the once "unsinkable ship". April 15, 1912 the Titanic sank into the Atlantic Ocean on it's one and only voyage. The 825 ton ship can be found 400 miles off the coast of Newfoundland 12,600 feet below the Atlantic.
Our new understanding of the solar system and the technology we’ve developed through conducting missions has benefitted our society by helping us understand things about other planets, space, and most importantly help us understand more things about our home, planet Earth.
Despite the amounts of incoming radiation, very little actually reaches the Earth’s surface. One layer of protection the Earth provides is in the form of a magnetic field that deflects charged particles from reaching the Earth’s surface. This magnetic field is generated by a combination of the liquids within the Earth’s core and the interplanetary magnetic field generated by the Sun. This field reaches out thousands of miles from Earth, so when solar wind travels through space and encounters Earth’s
The story of "Benito Cereno" contains a vicious mutiny at sea aboard the San Dominick plotted and carried out by the "valuable [human] freight" (39) - the slaves. Subsequently, this insurrection is veiled in a calculated façade to fool a naïve American captain named Delano who is unable to believe in the "malign evil in man" (37). Delano remains complacent throughout his time on the San Dominick unaware of the many indications suggesting a much more sinister situation engulfing the ship. However, clues throughout the discourse suggest what is occurring via death-filled imagery. The use of imagery associated with death in "Benito Cereno" serves on the periphery as a connection to the violent nature of the ships
Explorer II (March 5, 1958) and Explorer V (August 24, 1958) were both failures because they failed to reach orbit. But along with these two failures, two more successes were had. von Braun’s team successfully launched the Explorer III on March 26, 1958, and the Explorer IV on July 26, 1958. Unlike its Soviet predecessor, these satellites were infinitely more sophisticated with instruments to study the Earth's upper atmosphere and its interaction with cosmic rays. The information collected by the Explorers led to the discovery of the Van Allen belts, donut shaped regions of highly energetic charged particles that are trapped in the higher altitude regions of the magnetic fields of earth, and protect it from harmful ultraviolet rays emitted by the Sun. In comparison to the launch of the Vanguard series, the Sputnik I ‘s launch was one of detriment to the prestige. But the Explorer series of satellites questioned the functionality of the Sputnik I’s technologically-lacking
The solar wind containing these hot gases races toward the edges of the solar system, and smash in to the magnetosphere. The magnetosphere protects the earth by deflecting most of the solar wind around the planet. Trillions of these charged particles mange to get through and project from the North and South poles. Energy released in this fashion excites atoms of nitrogen and oxygen, which in turn emit pulses of colored light. These formations are called an aurora. The aurora borealis, which are visible in Alaska, are a result of this sort of space storm.
Due to the large number of space exploration projects, a large belt of debris has formed that can be hazardous to other operational spacecraft. As engineers, we have an ethical responsibility to prevent pollution of Earth’s atmosphere. We have learned a hard lesson on the value of environment from right here on Earth. Trends show that the debris belt circling the Earth will only get bigger, and become more hazardous to spacecraft.
