Sustainability and Innovation in Space

The video discusses the observation of Earth from satellites, highlighting the challenges of space debris and sustainability. It explores the lifecycle of satellites, focusing on safe disposal methods. Innovative solutions like wax-based fuels are proposed for sustainable space missions. The video also envisions sustainable living systems for future space habitats, emphasizing the importance of closed systems to reduce waste.

What is the speed at which astronauts travel on the Space Station?

• 20,000 miles per hour

• 17,500 miles per hour

• 25,000 miles per hour

• 10,000 miles per hour

What is a major concern when small objects collide in space?

• They slow down the Space Station

• They increase the speed of satellites

• They create new satellites

• They cause dangerous collisions

What has been a traditional goal in satellite construction?

• To make them invisible

• To launch them frequently

• To ensure they last as long as possible

• To make them as small as possible

What is the geostationary belt?

• A ring of new satellites

• A belt of asteroids

• An area 36,000 kilometers from Earth

• A region close to the Earth's surface

What is a challenge with satellites in the geostationary belt?

• They are invisible to tracking systems

• They are too expensive to launch

• They are difficult to destroy or use safely

• They are too close to Earth

What is a proposed non-toxic fuel for satellites?

• Hydrazine

• Beeswax

• Kerosene

• Liquid hydrogen

Why is beeswax considered for satellite fuel?

• It is the cheapest option

• It is a global product and non-toxic

• It is the most powerful fuel

• It is highly explosive

What is the benefit of using wax-based fuel systems?

• They increase satellite speed

• They help deorbit satellites safely

• They make satellites invisible

• They extend satellite life indefinitely

What is the vision for sustainable living in space?

• To increase the number of satellites

• To build larger space stations

• To create waste-free systems

• To colonize multiple planets

How can innovations in space sustainability benefit Earth?

• By applying waste reduction techniques

• By reducing Earth's population

• By increasing Earth's gravity

• By making Earth more colorful
