In recycling, raw materials that have already been obtained are used, which reduces the need for more materials to be extracted. If we recycle enough to slow the rate of extraction bringing it lower or equal to the rate that our resources replenish themselves we are living sustainable. This project is especially important because it focuses on recycling objects that take a lot of resources to make and that can't be organically broken
Richard Xu ESS102 AD 4/13/17 Research Paper RD Topic: Space Debris As Earth becomes more technologically innovated and crowded, space has become the answer of many of our problems. Over the past couple of decades, we have launched numerous contraptions into space such as satellites in which many currently orbit the Earth. These contraptions can be used for reconnaissance, communications, weather, search and rescue, navigation, exploration, television, and much more. Not a day passes by where we do not make use of these contraptions in our lives. However, as we progress towards the future, more and more of these satellites will be launched into orbit and as the fate of technology, they are bound to fail at some point and often get abandoned.
Although space junk may seem trivial,it is in fact crucial in terms of today's concern over everyday life. Apparently Nasa has just been throwing it out the window into our atmosphere, which is causing a gigantic problem. Some experts say there are just some things like satellites they cannot take back to earth. They say that they would only do it in in rare cases. If they take the things up there how come they can't take back it down to earth. They are trying to find a way to bring the trash back.
Where does this debris come from or how is it formed? Over 50 years, around 6600 satellites have been placed into orbits after more than 4900 were already launched . Today only around 1000 satellites are still in service. The rest are just left in orbits. US Space Surveillance Network tracks more than 23000 space objects orbiting the Earth; some of the objects are about 5 to 10 cm in size in low earth orbit while other ranging measured from 10cm to 1 m are located at geostationary altitudes. All these spotted space objects will be documented by US Space Surveillance Network in their catalogue. Of all the catalogued objects, 6 % are spacecraft and about 30 % are from retired satellites and discarded parts from rocket such as spent upper stages, launch adapter and lens cover. Explosion of rocket bodies is the primary contributor for space debris. This
1 JJT Task 1 – Social Responsibility Strategies 2 A small business, which shall be named for the purposes of this report SE Construction, will be reviewed in relationship to social responsibility in a business. In the corporate world this is called “Corporate Social Responsibility (CSR)”. Corporate Social Responsibility “generally refers to the idea that corporations have
Recycling is a very essential and crucial process in our world today. The term recycling means that waste can be converted into new products instead of being discarded. As the population continues to grow, humans are using more and more products. In order to reduce
As of December 2015 there were 1071 operational satellites around the Earth and over 21.000 objects larger than 10cm hurtling around the planet (Universetoday). In 2013 there were 81 space launches and in 2014 that number increased to 92 space launches. 2014 had the highest number of space launches in a year in more than two decades (spaceflightnow). If those on Mars could cut back on the number of Satellites they put up they would have a significantly lower statistical probability of collisions. This would make long term space use possible.
Some researchers from China’s Tsinghua University have came up with an idea that might help with this problem. They want to build a craft to go into space and collect the junk and turn it into fuel. I think this is an excellent way to take care of the problem. The article The Quest To Find a Solution To Clean Space Junk Continues says that they call the rocket the “debis engine”, and it catches anything 10cm in diameter, with the help of nets. The rocket would have
Without the proper mitigation techniques, space travel could have more space-junk-related mishaps as time goes on. Luckily, the agencies responsible for most of the world’s spacecraft are already working to prevent any exponential growth of space junk, and until then, procedures are in place to prevent any catastrophic accident from occurring. As the years progress, space junk will evolve from a connotation of fear with the misinformed and annoyance with those knowledgeable, to a relic of the past, dealt with as regularly as
After a short five years of experimenting, in February of 2015, Japan’s space agency, JAXA, will launch this spacecraft designed of a steel net that will capture space junk (Anthony, 2014). The net itself is a mile long and attached to a satellite (“Space net for orbiting debris proposed”). Interestingly, JAXA is working will a fishing equipment company that is able to make the steel and aluminum wired mesh for the net. The idea is that the electromagnetic force created by the metal net will be the force that captures the debris (Anthony, 2014). As the net becomes full, it will be released from the spacecraft, and the net will be attracted to Earth’s magnetic field, deorbit, and burn in the atmosphere (“Space net for orbiting debris
There has been a lot of talking about the increasing problem of space debri because of the amount of trash that we globally have thrown into space each year. People don’t know that having so much junk out there in the atmosphere is dangerous

There is an ethical issue vs. a legal issue vs. a cost issue that is very much open to debate. Several decades of space exploration have led to a buildup of non-functional "space junk". However, proper disposal of equipment is just added cost for a space program that is already on a tight budget. If space is in fact the "final frontier", then we must learn from our mistakes here on earth and minimized the contamination and pollution of the space. As engineers, we have a moral responsibility to do everything in our power to preserve the environment. We are all stakeholder in this issue because it involves our tax money to fund a lot of these outer space project. But more important emphazies should be made on precerving and taking good care of the evironment we live in and the ones we explore such the outerspace. Back
Orbital mechanics is the application of ballistic and celestial mechanics to motion, especially pertaining to rockets and spacecraft. Many famous physicists and mathematicians have helped develop equations, formulas, and laws to understand different aspects of orbital mechanics; such as Newton with centripetal force and the gravitational constant (GM) and also Kepler and his three laws of planetary motion. Though my interest did not sprout from who was involved with orbital mechanics, but the orbital mechanics themselves. I’ve always had an interest in astronomy and physics, and this seems like the perfect combinations of both.
