Скачать или смотреть 3.7 | Electric, Nuclear & Solar Rockets | Rocket Science for Everyone with Marla Geha

Ever wondered what propels spacecraft beyond the initial launch? While chemical rockets are crucial for getting off Earth, this lesson delves into three fascinating alternatives used once in orbit: electric (ion) propulsion, nuclear thermal rockets, and solar sails. Discover how each method works, their unique advantages for different space missions, and their limitations compared to traditional chemical propulsion.

🎯 Learning Objectives
• Explain why alternative propulsion methods are necessary for spacecraft once in orbit.
• Describe the mechanism and applications of electric (ion) propulsion systems.
• Understand the principles and potential uses of nuclear thermal rockets for deep space travel.
• Grasp how solar sails generate thrust and their suitability for long-duration voyages.
• Compare the advantages and limitations of electric, nuclear, and solar propulsion methods.

📚 About the Course
This course is an intuitive introduction to rocket science in our everyday lives.
Modern life increasingly depends on technology provided by Earth-orbiting satellites, from detailed weather predictions to broad-band internet and GPS. How are satellites launched into orbit and how do they work once they get there? Why are rockets used to get into orbit and how are they different from airplanes? This introductory course is aimed at a wide non-technical audience and is appropriate for all ages.
