SOLVENCY: REMOVING FEW OBJECTS ENOUGH
REMOVING JUST FIVE LARGE OBJECTS A YEAR CAN SOLVE-Szoka and Dunstan ‘09

But the problem can be solved. Thus far, governments have simply tried to mandate “mitigation” of debris-creation. But just as some warn about “runaway warming,” we know that mitigation alone will not solve the debris problem. The answer lies in “remediation”: removing just five large objects per year could prevent a chain reaction. If governments attempt to clean up this mess themselves, the cost could run into the trillions—rivaling even some proposed climate change solutions.
ONLY THE REMOVAL OF EXISTING LARGE OBJECTS CA PREVENT CASCADE EFFECT-Ansdell ‘10

As early as 1978, scientists postulated that the runaway growth of space debris owing to collisional cascading would eventually prohibit the use of Earth’s orbit (Kessler and Cour-Palais 1978). Recent scientific studies have also predicted uncontrolled debris growth in low-Earth’s orbit over the next century. One NASA study used predictive models to show that even if all launches had been halted in 2004, the population of space objects greater than ten centimeters would remain stable only until 2055 (Liou and Johnson 2006). Beyond that, increasing collisions would create debris faster than debris is removed naturally, resulting in annual increases in the overall space object population. The study concluded that, “only the removal of existing large objects from orbit can prevent future problems for research in and commercialization of space” (Liou and Johnson 2006, 340). The European Space Agency (ESA) has come to similar conclusions using its own predictive models (ESA 2009a).
SIMPLY REMOVING FIVE PIECES OF DEBRIS A YEAR IS ENOUGH-Johnson and Hudson ‘08

If the orbital debris population remained as it is today with no additional space operations, the level of fragmentation in Earth’s orbit would continue to escalate exponentially. Dr. Nicholas Johnson, chief scientist for orbital debris for NASA at the Johnson Space Center, has modeled future orbital debris scenarios based on non-mitigation over a 5, 10, and 20 year period compared to the removal of one to five pieces of debris beginning in the year 2020. This paper, co-authored by J.-C. Liou and titled “A Sensitivity Study of the Effectiveness of Active Debris Removal in LEO,” suggests that the orbital debris population can be effectively addressed by simply removing five objects per year starting in the year 2020.
SOLVENCY: THE US SHOULD LEAD
THE UNITED STATES SHOULD TAKE THE LEAD ON REMOVING SPACE DEBRIS-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
Space debris increasingly threatens the provision of satellite services that have become integrated into the operations of the global economy and U.S. military, such as GPS precision timing and navigation. While studies suggest that annually removing as few as five massive pieces of debris in critical orbits could significantly stabilize the space debris environment, countries have hesitated to develop space debris removal systems due to high costs and classic free rider problems. This paper argues that the United States should take the lead in immediately developing systems to remove space debris with the greatest potential to contribute to future collisions. Although leading by example will entail certain costs and risks, U.S. leadership in preserving the near-Earth space environment will result in not only long-term benefits for the United States, but also the fulfillment of U.S. national space policy and broader U.S. foreign policy objectives.
ONE COUNTRY SHOULD TAKE THE LEAD BY ESTABLISHING A NATIONAL DEBRIS REMOVAL PROGRAM, SPEEDING INTERNATIONAL AGREEMENT AND TECHNOLOGY-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
Space debris removal systems could take decades to develop and deploy through international partnerships due to the many interdisciplinary challenges they face. Given the need to start actively removing space debris sooner rather than later to ensure the continued benefits of satellite services, international cooperation may not be the most appropriate mechanism for instigating the first space debris removal system. Instead,one country should take a leadership role by establishing a national space debris removal program. This would accelerate technology development and demonstration, which would, in turn, build-up trust and hasten international participation in space debris removal.
THE US IS AN IDEAL CANDIDATE TO REMOVE DEBRIS; SIMPLY REMOVING 5 PIECES A YEAR IS ENOUGH-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
As previously discussed, a recent NASA study found that annually removing as little as five massive pieces of debris in critical orbits could significantly stabilize the long-term space debris environment (Liou and Johnson 2007). This suggests that it is feasible for one nation to unilaterally develop and deploy an effective debris removal system. As the United States is responsible for creating much of the debris in Earth’s orbit, it is a candidate for taking a leadership role in removing it, along with other heavy polluters of the space environment such as China and Russia.
IF THE US FAILS TO LEAD INTERNATIONAL EFFORTS TO CLEAN DEBRIS, WE RISK SUSTAINABLE DEVELOPMENT OF THE EARTH’S NEAR-SPACE ENVIRONMENT-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
If the United States and other powerful governments do not take steps now to avert the potentially devastating effects of space debris, the issue risks becoming stalemated in a manner similar to climate change. Given the past hesitation of international forums in addressing the space debris issue, unilateral action is the most appropriate means of instigating space debris removal within the needed timeframe. The United States is well poised for a leadership role in space debris removal.
Going forward, the U.S. government should work closely with the commercial sector in this endeavor, focusing on removing pieces of U.S. debris with the greatest potential to contribute to future collisions. It should also keep its space debris removal system as open and transparent as possible to allow for future international cooperation in this field.
Although leadership in space debris removal will entail certain risks, investing early in preserving the near-Earth space environment is necessary to protect the satellite technology that is so vital to the U.S. military and day-to-day operations of the global economy. By instituting global space debris removal measures, a critical opportunity exists to mitigate and minimize the potential damage of space debris and ensure the sustainable development of the near-Earth space environment.
THE US COULD ENSURE THAT OTHER NATIONS JOIN IN LATER OR PAY FOR REMOVAL-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
Moreover, current U.S. National Space Policy asserts that the United States will take a “leadership role” in space debris minimization. This could include the development, deployment, and demonstration of an effective space debris removal system to remove U.S. debris as well as that of other nations, upon their request. There could also be international political and economic advantages associated with being the first country to develop this revolutionary technology. However, there is always the danger of other nations simply benefiting from U.S. investment of its resources in this area. Thus, mechanisms should also be created to avoid a classic “free rider” situation. For example, techniques could be employed to ensure other countries either join in the effort later on or pay appropriate fees to the United States for removal services.
EVEN IF THERE ARE COSTS TO THE UNITED STATES, IT MUST LEAD THIS EFFORT-Ansdell ‘10

SOLVENCY: TIME TO ACT IS NOW
POLICYMAKERS MUST TAKE DECISIVE ACTION TO AVOID THE TRAGEDY OF THE COMMONS IN SPACE; THE TIME TO ACT IS NOW-Ansdell ‘10
[Megan; graduate student, George Washington, International Science and Technology; Active Space Debris Removal: Needs, Implications, and Recommendations for Today’s Geopolitical Environment; Journal of Public and International Affairs; 2010]
The biggest challenge, however, will be simply starting the process of active debris removal. Despite growing consensus within the space debris community that active removal will be needed over the next several decades, the fact that space activities continue today without significant interference causes the larger global community to not see space debris as an issue. Moreover, space suffers from the “tragedy of the commons,” a phenomenon that refers to the overexploitation of a shared resource when there is no clear ownership over it. This, in addition to the abovementioned challenges facing debris removal systems, means that the natural tendency of those in power will likely be to do nothing until they absolutely must. This is reminiscent of responses to climate change, where the failure of governments to take responsibility for their past actions and act preemptively is compromising the larger global good. Policy makers must therefore take necessary actions, as recommended in next section of this paper, to prevent what is now happening on Earth from also occurring in space.
DOUBLING THE AMOUNT OF DEBRIS WE REMOVE CAN GET THE PROBLEM UNDER CONTROL-David ‘10

As the atmospheric density in the thermosphere decreases, however, debris can remain in orbit up to 25 percent longer, said Hugh Lewis, from the university's School of Engineering Sciences.
"The fact that these objects are staying in orbit longer counteracts the positive effects that we would otherwise see with active debris removal," Lewis said.
The research team suggests that international efforts to control the growth of space debris may become much less effective in the future if these atmospheric changes continue.
"Our study shows that if we double the number of debris objects we can remove each year, we can get back on track with reducing the debris population. Achieving this target, however, will be challenging," Lewis said.

Now is the time to reduce the threat to both human spaceflight and satellites from destructive space debris.
That viewpoint emerged from a major gathering of space experts at the International Interdisciplinary Congress on Space Debris, held May 7-9 at the Faculty of Law, McGill University in Montreal, Canada.
The Congress brought together legal, policy, and technical experts from around the globe, including the U.S., Russia, India, China, Canada, and Europe, a unique gathering of officials to thrash out legal, and technical ideas for the next phase of dealing with the space debris issue.
ADVANTAGE 1: DEBRIS BLOCKS SPACE EXPLORATION
FAILURE TO CONTROL SPACE DEBRIS ENDS HOPES OF SPACE COLONIZATION AND CLEAN ENERGY FROM SOLAR POWER SATELLITES-Szoka and Dunstan ‘09

As world leaders meet in Copenhagen to consider drastic carbon emission restrictions that could require large-scale de-industrialization, experts gathered last week just outside Washington, D.C. to discuss another environmental problem: Space junk.[1] Unlike with climate change, there’s no difference of scientific opinion about this problem—orbital debris counts increased 13% in 2009 alone, with the catalog of tracked objects swelling to 20,000, and estimates of over 300,000 objects in total; most too small to see and all racing around the Earth at over 17,500 miles per hour. Those are speeding bullets, some the size of school buses, and all capable of knocking out a satellite or manned vehicle.
At stake are much more than the $200 billion a year satellite and launch industries and jobs that depend on them. Satellites connect the remotest locations in the world; guide us down unfamiliar roads; allow Internet users to view their homes from space; discourage war by making it impossible to hide armies on another country’s borders; are utterly indispensable to American troops in the field; and play a critical role in monitoring climate change and other environmental problems. Orbital debris could block all these benefits for centuries, and prevent us from developing clean energy sources like space solar power satellites, exploring our Solar System and someday making humanity a multi-planetary civilization capable of surviving true climatic catastrophes.
SPACE DEBRIS THREATENS SATELLITES WHICH ARE THE SOFT UNDERBELLY OF AMERICAN NATIONAL SECURITY-Imburgia ‘11

Simply put, the United States depends on space-based assets for national security, and those assets are vulnerable to space debris collisions. As Massachusetts Democratic Congressman Edward
Markey stated, ““American satellites are the soft underbelly of our national security.””161 The Rumsfeld Commission set the groundwork for such a conclusion in 2001, when it discussed the vulnerability of U.S. space-based assets and warned of the Space Pearl Harbor.162 Congress also recognized this vulnerability in June 2006, when it held hearings concerning space and its import to U.S. national power and security.163 In his June 2006 Congressional Statement, Lieutenant General C. Robert Kehler, then the Deputy Commander, United States Strategic Command, stated that ““space capabilities are inextricably woven into the fabric of American security.””164 He added that these space capabilities are ““vital to our daily efforts throughout the world in all aspects of modern warfare”” and discussed how integral space capabilities are to ““defeating terrorist threats, defending the homeland in depth, shaping the choices of countries at strategic crossroads and preventing hostile states and actors from acquiring or using WMD.””
CONTROLLING THE PRODUCTION OF DEBRIS IS CRITICAL TO PRESERVE THE LONG-TERM USE OF SPACE-Wright ‘08

Space debris is any human-made object in orbit that no longer serves a useful purpose. It includes defunct satellites, discarded equipment and rocket stages, and fragments from the breakup of satellites and rocket stages.
Space debris is a concern because—due to its very high speed in orbit—even relatively small pieces can damage or destroy satellites in a collision. Since debris at high altitudes can stay in orbit for decades or longer, it accumulates as more is produced. As the amount grows, the risk of collisions with satellites also grows. If the amount of debris at some altitudes becomes sufficiently large, it could be difficult to use those regions for satellites.
Since there is currently no effective way to remove large amounts of debris from orbit, controlling the production of debris is essential for preserving the long-term use of space.
FAILURE TO DEAL WITH DEBRIS COULD MAKE SPACE EXPLORATION FINANCIALLY IMPOSSIBLE-Broad ‘07

If nothing is done, a kind of orbital crisis might ensue that is known as the Kessler Syndrome, after Mr. Kessler. A staple of science fiction, it holds that the space around Earth becomes so riddled with junk that launchings are almost impossible. Vehicles that entered space would quickly be destroyed.
In an interview, Mr. Kessler called the worst-case scenario an exaggeration. “It’s been overdone,” he said of the syndrome.
Still, he warned of an economic barrier to space exploration that could arise. To fight debris, he said, designers will have to give spacecraft more and more shielding, struggling to protect the craft from destruction and making them heavier and more costly in the process.
At some point, he said, perhaps centuries from now, the costs will outweigh the benefits.
“It gets more and more expensive,” he said. “Sooner or later it gets too expensive to do business in space.”
FAILURE TO CONTROL DEBRIS WILL INCREASE THE COST OF SPACE MISSIONS OR LEAD TO POLICIES THAT LEAD TO CHEAPER, MORE DEBRIS-PRODUCING CRAFT-Kessler ‘09
[Donald; PhD, 30 year researcher about orbital debris at NASA; 08 Mar 2009; http://webpages.charter.net/dkessler/files/KesSym.html; retrieved 16 Jun 2011]
We are entering a new era of debris control….an era that will be dominated by a slowly increasing number of random catastrophic collisions. These collisions will continue in the 800 km to 1000 km altitude regions, but will eventually spread to other regions. The control of future debris requires, at a minimum, that we not leave future payloads and rocket bodies in orbit after their useful life and might require that we plan launches to return some objects already in orbit.
These control measures will significantly increase the cost of debris control measures; but if we do not do them, we will increase the cost of future space activities even more. We might be tempted to put increasing amounts of shielding on all spacecraft to protect them and increase their life, or we might just accept shorter lifetimes for all spacecraft. However, neither option is acceptable: More shielding not only increases cost, but it also increases both the frequency of catastrophic collisions and the amount of debris generated when such a collision occurs. Accepting a shorter lifetime also increases cost, because it means that satellites must be replaced more often….with the failed satellites again increasing the catastrophic collision rate and producing larger amounts of debris.
SPACE DEBRIS FILLS ORBIT, THREATENING THE ENTIRE SPACE ENTERPRISE-Dickens ‘10

Note, for example, that there are now around fourteen thousand tracked objects circling around the earth, known as “space debris” or “space junk.” Improved tracking systems will increase the number of smaller, observable tracked objects to around thirty thousand, many of these causing potential damage. Even whole satellites may collide. Such collisions are estimated at millions or even billions to one. But on February 10, 2009, such a collision actually happened. A defunct Russian satellite crashed into an American commercial satellite, generating thousands of pieces of orbiting debris. Space junk poses a serious threat to the whole enterprise of space colonization, and plans are now afoot to launch even more satellites, designed to drag older satellites out of orbit in order to avoid collisions.
UNCHECKED KESSLER SYNDROME WILL END CHANCES OF GOING OUT INTO SPACE-Levi ‘09

The Kessler Syndrome is a theory raised by the scientist, Donald Kessler. According to Kessler’s calculations, even if we were to stop all launches into space today, all at once, the amount of garbage already accumulated has reached a critical mass. The mechanisms most responsible for the pollution of space are the collisions and explosions – each collision between two objects results in thousands of fragments scattered in space; these will then go on to collide with other objects, creating further collisions. Within a few decades, Kessler hypothesized, the inevitable collision between pieces of garbage already out in space today will fill up space with countless dangerous particles. The particles will form a fatal cloak around the Earth, which will completely obliterate any possibility of going out into space. If this prophecy comes true, we might find ourselves in a situation in which entire generations on Earth will not be able to develop advanced space technology, which will have a serious negative impact on technology in general.
