Can space debris block the sun?
To keep the debris directly over a location it would basically be a geostationary orbit, but it would only block the sun around ‘noon’ depending on the size of it and the season. In this case it would also act like an extra moon at night as well.
What protects the Earth from radiation and space debris?
The magnetosphere is a high layer of the atmosphere. As the name suggests, Earth’s magnetic field lies here, acting as a shield to the solar and cosmic particle radiation, and solar winds. Solar winds can damage and somehow ‘blow away’ the Earth’s atmosphere, but the magnetosphere prevents that.
What can space debris do?
While space debris is unlikely to affect space travel, it will lead to significant problems for spaceflight around Earth. The risk would be highest for objects orbiting at an altitude of around 1,000 kilometres (620 miles), which is used for communications and Earth observation.
What is the problem with space debris?
Human activities leave too many dead satellites and fragments of machinery discarded in Earth orbit. If left unchecked, space junk could pose significant problems for future generations — rendering access to space increasingly difficult, or at worst, impossible.
Why space debris is bad?
The danger in this scenario is that self-perpetuating debris fields in orbit will impede space exploration. With even tiny collisions having the potential to cause catastrophic damage, launching payloads and crews to space will simply be too hazardous and expensive.
How can you protect against space radiation?
To protect against this type of radiation, space agencies and commercial aerospace manufacturers will typically encase sensitive electronics in metal boxes. While metals like lead or depleted uranium provide the most protection, this kind of shielding would add a significant amount of weight to a spacecraft.
Can you see space debris from Earth?
Thuy Nguyen-Onstott. One may ask, “What is Orbital Debris?” Although we don’t see space junk in the sky, beyond the clouds and further than the eye can see, it enters low Earth orbit (LEO). Most “space junk” is moving very fast and can reach speeds of 18,000 miles per hour, almost seven times faster than a bullet.
