Space Travel and Artificial Gravity

The video discusses a mission to colonize Alpha Centauri using a space ark. It highlights the challenges of long-term space travel, such as the effects of zero gravity on the human body, including bone and muscle loss. Solutions like exercise and artificial gravity through centrifugal force are explored to mitigate these issues, ensuring the health and safety of the crew on their 40-year journey.

What is the primary goal of the space ark mission?

• To return to Earth

• To study black holes

• To colonize a distant planet

• To explore the solar system

Which star system is the first target for the space ark?

• Proxima Centauri

• Alpha Centauri

• Betelgeuse

• Sirius

What happens to human bones in zero gravity?

• They demineralize

• They grow faster

• They become stronger

• They remain unchanged

How much bone mass is lost per month in space?

• 1%

• 5%

• 2%

• 10%

What is a major effect of space travel on the cardiovascular system?

• Decreased blood volume

• Increased heart rate and blood pressure

• Improved circulation

• Enhanced oxygen absorption

How long are astronauts scheduled to exercise daily on the space station?

• 3 hours

• 2 hours

• 1 hour

• 4 hours

Why is artificial gravity necessary for long space journeys?

• To improve communication
