3.2 | Why Planes Can’t Reach Space | Rocket Science for Everyone with Yale’s Marla Geha

Ever wondered why we use massive rockets instead of sleek airplanes to launch vehicles into space? This lesson dives deep into the fundamental differences between airplanes and rockets, explaining why jet engines, despite their power, simply can't get us to orbit. We'll explore the critical role of air, the concept of lift, and the astonishing amount of fuel required for space travel.🎯 Learning Objectives• Understand the fundamental differences between airplane jet engines and rocket engines.• Explain why jet engines are unsuitable for space travel, considering air requirements and lift.• Compare the astonishing fuel-to-mass ratios required for Earth-bound vehicles versus spacecraft.• Recognize the immense challenges and ingenuity involved in launching objects into space.📚 About the CourseThis 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. 📺 Watch the full playlist on YouTube: https://www.youtube.com/playlist?list=PLh9mgdi4rNexC1fSWLlpQx_Gjj_0DhjVE 🎓 Enroll on Coursera for assessments and a certificate: https://www.coursera.org/learn/rocket-science-for-everyone 🌐 Explore more learning opportunities on Yale Online: https://online.yale.edu/courses/rocket-science-everyone #RocketScienceForEveryone #RocketsVsPlanes #SpaceExploration #STEMEducation #AerospaceEngineering #Physics #OnlineLearning #YaleOnline #RocketLaunch #SpaceScience Learn more about your ad choices.
