Space Debris Management Solutions

The video discusses the growing problem of space debris in Earth's orbit, highlighting the risks of collisions and the potential for the Kessler syndrome. It explores various solutions, including harpoons, nets, and lasers, and emphasizes the need for international cooperation and legal adjustments. The video also covers the importance of mitigation efforts to prevent new debris and the role of commercial companies in addressing the issue.

What is the primary concern with the increasing amount of space debris?

• It may cause satellites to malfunction.

• It could block sunlight from reaching Earth.

• It could lead to uncontrollable collisions in space.

• It might increase the Earth's gravitational pull.

What is the Kessler syndrome?

• A theory about the expansion of the universe.

• A scenario where space debris causes a chain reaction of collisions.

• A method for cleaning up space debris.

• A type of satellite orbit.

Which of the following is NOT a proposed solution for space debris removal?

• Magnetic fields

• Tungsten dust clouds

• Physical sweepers

• Trash collecting spacecraft

What is a major drawback of using tungsten dust to remove space debris?

• It is too expensive.

• It could contribute to space pollution.

• It is ineffective against large debris.

• It requires constant maintenance.

How do lasers help in managing space debris?

• By nudging debris into safer orbits.

• By slowing down debris with magnetic fields.

• By attracting debris to a central point.

• By vaporizing debris completely.

What is a 'laser broom'?

• A tool for cleaning satellite surfaces.

• A method for detecting space debris.

• A laser system that nudges debris out of orbit.

• A device that sweeps debris into a collection bin.

What is a key advantage of space-based laser systems over ground-based ones?

• They can use Earth's power grid.

• They are easier to maintain.

• They have a better angle for targeting debris.

• They are cheaper to build.

What is the main obstacle to implementing laser systems for debris removal?

• Insufficient interest from space agencies.

• High cost and funding issues.

• Lack of technological capability.

• International legal restrictions.

What does the European Space Agency's Zero Debris Charter emphasize?

• Building larger space stations.

• Increasing the number of satellites in orbit.

• Developing new space exploration missions.

• Preventing the creation of new space debris.

What is a significant legal challenge in cleaning up space debris?

• Lack of international cooperation.

• Prohibition on touching objects not launched by the same entity.

• Inability to track small debris.

• Insufficient technology for debris removal.
