Reveal Answers

1. b

2. b

3. a

4. a

5. c

6. True

7. True

8. False

9. The breakthrough was the development of a nuclear fusion propulsion system that allowed the spacecraft to travel at a significant fraction of the speed of light, making it possible to reach Proxima b in under 50 years.

10. The main challenges included extreme weather conditions and the planet's variable magnetic field. The astronauts used specially designed habitats and equipment to adapt to the changing environment and ensure their safety.
