The Forecast on Space Junk
It is a wonder to marvel about how much debris man has created over the span of approximately 50 years. Sadly, this is nothing new on our planet. However, little is known, or at least in regards to public awareness, about the celestial landfill that man has created since the early days of the Space Race involving the Russian launching of Sputnik. Ever since then, the repercussions of the US versus Russia mechanized frenzy have snowballed into an estimated 6,600 satellites being launched, in addition to 1,000 that are still active now.
According to NASA, more than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth- just hundreds of miles above us. Space junk-which is also known by the names space and orbital debris, are made up of a mixture of natural (meteorites) and man-made materials that no longer serves a further purpose or function.
So what are some examples of Space Junk? Inventory includes everything from old satellites, shards of space craft and shrapnel, and floating reminders of failed missions. Even tiny specks of paint from shuttles or bolts and screws are magnified in power when travelling amongst the various debris in this orbit around Earth. Other obscure objects include unused launch vehicle stages, an astronaut’s wrench, and lens covers (ESA, 2013).
These miscellaneous pieces, ranging from the size of a marble to a softball, travel at speeds up to 17,500 mph. The rising population of space debris increases the foreseen danger to all space vehicles, but especially to the International Space Station, space shuttles and other spacecraft with humans aboard (NASA, 2012).
Believe it or not, the real problem is not the fact that there are millions of pieces of debr...

...official policy of the U.S. has been to minimize the creation of new orbital debris. The most recent National Space Policy in 2010 “addresses the importance of preserving the space environment, including orbital debris mitigation. NASA and the Department of Defense are also directed to pursue research and development of technologies and techniques to mitigate and remove on-orbit debris, reduce hazards, and increase the understanding of the current and future debris environment” (ESA, 2013). Further efforts have been made through NORAD (North American Aerospace Defense Command) located in the U.S., to keep tabs on any piece of debris that classifies as the size of a softball or larger. In closing, there are steps and precautions that can be made when approaching the subject of Space Junk, and like Kessler, all can share in the reassurance that time will heal itself.
2. Space is a big place, it is constantly expanding, probes sent into space haven’t even reached the edge of the solar system, and people have only been as far as the moon. When looking at space from a distance the Earth is nothing when compared to the whole of space. The Air Force Space Command is made up of over 38,000 people at over 130 locations across the globe, this includes cyberspace as well.1 Space has a several traits that
When we made it to space there was space junk and there was lots of it. It is everywhere and we couldn’t see anything because our windows were covered with junk. So we had to go outside with our space suits to get rid of the junk. It took a long time but we managed. After that, there was more space junk and it got in our engines. Our engine is full of it and then the main engine failed so we only had the jet engine and the backup engine.

The Space Race is remarkably similar to that of the arms race because of the parallel between the creation of the atomic bomb and the goal of reaching the moon. The United States’ bombing of Hiroshima and Nagasaki effectively established its place as the technologically superior nation; however, major milestones in space achieved early by the Soviets damaged America’s reputation. In 1957, Soviet scientists shocked the world by successfully launching the Sputnik 1, the first artificial satellite, beyond the Kármán Line (the boundary of space). This amazing breakthrough “rattled American self-confidence. It cast doubts on America’s vaunted scientific superiority and raised some sobering military questions.” This blow to national pride along with the fear that the Soviets could potentially launch ICBMs from space led to “Rocket fever”. The sudden wave of nationalism and the desire to build a space program worthier to that of the Soviet Union led to the...
The Great Pacific Garbage Patch, also known as the Pacific trash vortex, is a collection of litter which has ended up in oceans, seas and other large bodies of water. The Great Pacific Garbage Patch spans from the West Coast of America to Japan. These areas are linked together by the North Pacific Subtropical Convergence Zone; this convergence zone acts as a highway for litter to move from one patch to another. It has also been theorised that the ocean floor beneath the Great pacific garbage patch is also littered with a lot of rubbish on its own. This is a valid theory because it has been proven by Oceanographers and Ecologists that 70% of marine debris actually sinks down to the ocean floor. Although the scientists have researched this garbage vortex, they did not find it. However, when the founder of this garbage vortex, Charles Moore, was boat racing, he found this garbage vortex while he was travelling from Hawaii to California. He and his crew members noticed that their ship was surrounded by millions of
Space is also governed by rules and laws much like we do on land and sea. “Treaty on Principles Governming the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies,” or commonly referred to as the Outer Space Treaty was signed in 1966 by many nations, including the Unites States, and is the basis for most international space laws and policies. Some key points to take away from this treaty in relation to the space weapons debate are the following: “(1) outer space is open to all nations to explore and use; (2) nations cannot own any portion of outer space; (3) outer space will be used for peaceful purposes; (4) nations cannot place, put in orbit, or station any weapons of mass destruction in any form in outer space.” (UNOOSA) These principles and laws are also mostly reflected in our nation’s space policy, and our national security space strategy.

Comets and asteroids. They are some of the first celestial bodies that humans observed and truly thought about. From ancient cultures interpreting these near-Earth objects as signs of disaster, to 18th century Europeans studying their paths, to even the extinction of the dinosaurs, comets and asteroids have always been prevalent in the majority of Earth’s history. These objects have intrigued the human race for generations, and continue to do so today. These similar subjects of fascination have many unique and interesting characteristics and a rich history with Earth.
INTRODUCTION Attention-getter: “Space travel benefits us here on Earth. And we ain’t stopped yet. There’s more exploration to come.” (Nichelle Nichols from Star Trek) Credibility: Throughout our childhood as we study space, solar systems, planets we all come to a point of having the dream of exploring the space or learn more about it in the future.
Space trash is any discarded object in space that is harmful to every living being on earth. Since the nineteen-fifties we have been launching items into space. With our hopes and dreams in hand we hoped for the best but that is not what happened at all. There are millions upon millions upon millions of space junk in space. Now there is no possible way to get rid of all the debris, but with the cooperation of all nations we can help to stop the spread of this debris once and for all. Space leaders are in danger of all the harmful objects we have put into space. Space trash comes in many different forms which cause danger to current and future explorations in space.
Once NASA was given the right to start constructing The Hubble Space Telescope, or paraphrased as the HST, it cost $1.5 billion dollars to construct. The length of this massive piece of technology is 43.5ft long( 13.2m). The HST has a diameter of 14ft(4.2m) that allows it to store its hard drives, processors and other fragile technical organs inside the telescope. With its metal base, solar panels, mirrors and etc. protecting the telescopes fragile insides from floating space debris, the HST weighs in at 24,500 pounds, 11,110Kg(“The Telescope”).

It all started on October 4, 1957, when the U.S.S.R. launched Sputnik 1 into space. The Sputnik (“traveler” in Russian) was the first satellite made by mankind. It consisted in a small beeping metal ball, with a diameter of less than two feet and a weight of less than 200 pounds. The ball was small, but it started a big space race between the U.S.S.R. and the U.S. This race lasted for about twenty years and, without a doubt, it completely changed the world.

We have benefitted our world by using satellite technology to preform tasks and provide a range of innovated services. The main applications of satellites are in the fields of communication, Earth Remote Sensing, weather, and scientific research. In some ways the use of satellites has made our world smaller. Satellites make it possible to establish a connection between two people that are on opposite ends of the globe via a telephone call or the use of the internet. Each of these satellites have many parts, but two parts are common to all satellites are called the payload and the bus. These groups of devices make the satellite capable of accomplishing their tasks.
