There are some unresolved issues regarding LEO satellite coverage, in order to provide wireless communications from space.
With countdown to 19 and 20 MarchY Global protest actions, coinciding with moderation, we’ll look at some of the concerns voiced by experts and the informed public.
Part 1: There are no litter boxes and no trash pickup in space.
PHYS.ORG: ”Collisions involving large satellites at very high speeds (known as super-velocity) are rare and dangerous, They generate clouds of debris that endanger spacecraft around the planet. The first time this happened was in 2009 when the active communications satellite Iridium 33 struck the decommissioned Russian satellite Cosmos 2251, resulting in a debris field of about 1,000 large objects in low Earth orbit.[1]
Interested Scholars Union: “Debris in low earth orbit travel at 30 times faster than commercial jets. Pieces of debris larger than 1 cm (half an inch) can severely damage or destroy a satellite, It is not possible to effectively protect against debris of this size. China’s destruction of a relatively small satellite has doubled the debris threat to satellites in the most used portion of LEO. ” [2]
Popular Mechanics:Scientists want to destroy zombie moons with lasers. What could go wrong? This space junk solution may pose problems of its own. There are approximately 23,000 pieces of space debris larger than 10 centimeters orbiting Earth, including about 3,000 satellites, according to NASA’s Office of Orbital Debris Program (ODPO). If any piece of space junk collides with one another, the collisions could lead to large areas of debris that could disrupt many space activities, including the use of satellites, for generations. “The problem with lasers, as with a lot of space-based waste removal mechanisms, is that if you can remove a piece of trash from orbit, you can remove a working satellite,” says Gorman. “Any system to effectively remove orbital debris is also an effective anti-satellite weapon.””[3]

Space.com: “Thousands of more satellites will orbit Earth soon. We need better bases to prevent space accidents. Most satellites operate in low Earth orbit between 600 and 800 km above sea level. This is considered a busy area, as there are actually a lot of satellites there. Smaller satellites have a shorter lifespan than larger satellites, which usually orbit over low Earth orbit. However, removing the satellites could still take up to 150 years. By returning to the atmosphere and burning them, if they were about 750 km above sea level. Some are removed intentionally, through controlled re-entry, and others are designed to fall out in an unsupervised manner. Satellite and mega constellation operators should consider ways to reduce debris from these satellites beyond normal procedures, in order to maintain sustainable use of LEO. ” [4]
BUSINESS INSIDER: “What can Elon Musk’s 42,000 Starlink satellite do for and for the planet Over the next few decades, Elon Musk hopes to send 42,000 satellites into space. He hopes those satellites will bring high-speed internet to every corner of the world – from rainforests to Antarctica. But experts are concerned that the number of satellites could have a major impact on our planet. Its bright reflections are already obscuring the views of astronomers searching for deadly asteroids. If enough of them become disabled, which is already happening, they can also prevent space travel for decades.
As of early October, SpaceX has launched more than 700 satellites into orbit, with plans to launch a total of 12,000 satellites over the next five years, half of them by the end of 2024. Musk wants to add another 30,000 satellites into orbit, coming for a total of 42,000 satellites. An industrial orbiting the Earth. All of these satellites will also be much closer, anywhere from 200 to 400 miles above the planet in low Earth orbit. Each satellite will communicate with several others via lasers, creating something like a network backbone.
And to bring this internet into your home, you’ll need an antenna the size of a pizza. This staging array antenna can direct its beam to any satellite in the atmosphere, which will maintain the internet signal in your home. But this scheme is not without problems.
There is a concern about space debris, because when you have a lot of satellites in Earth’s closest, narrowest, and densest orbits, there is a greater chance that those satellites will collide with each other or with other satellites. These collisions create clouds of debris that can orbit the Earth for years, decades, or even centuries. This debris can then disable or cause other satellites to collide with each other, creating more debris, and this problem gets out of control in an effect called Kessler’s syndrome. And if we do get there, the space is essentially too insecure to be inaccessible.
SpaceX said its satellites could automatically move out of the way to avoid collisions. But dozens of SpaceX’s satellites are already deactivated and unable to move at all, posing a potential threat. And those interested in SpaceX’s plans are pressing the Federal Communications Commission (FCC) to rein in the company and regulate Low Earth Orbit more strictly. This could make the planned deployment of the 42,000 satellites more expensive and difficult. But it doesn’t stop at Starlink. Amazon’s Kuiper project, OneWeb, China’s Hongyan, and other projects are looking to challenge SpaceX by launching their own global networks of hundreds or thousands of satellites. If they all get what they want with little or no organization, We could end up with 100,000 satellites covering our planet over the next 10 years, which greatly increases the risk of space blocking for everyone. “[5] Video at the link
Despite the fact that we’re launching thousands of satellites without addressing disposal issues, we’ve figured out, however, how to hide communications electronics from the public, in a trash can, right here on Earth.
