ASTRONAUTICS
Understanding the Two Pillars of Aerospace Engineering
01 / INTRODUCTION
AEROSPACE
Aerospace Engineering is the branch of engineering dedicated to the design, development, and operation of aircraft and spacecraft. It is divided into two interconnected disciplines:
AERONAUTICS
Flight within Earth's atmosphere
Aircraft • Helicopters • Drones • Jets
ASTRONAUTICS
Flight beyond Earth's atmosphere
Rockets • Satellites • Spacecraft • Space Stations
"Together, they form the complete science of flight — from clouds to cosmos."
