History of Rockets

The development of rocket technology from early gunpowder weapons to modern launch vehicles and spacecraft, shaped by changing propulsion, materials, and military and scientific goals.

Chinese gunpowder: An explosive mixture of saltpeter, charcoal, and sulfur developed in China. Its invention enabled the first rocket-like weapons.
Rocket engine: A reaction engine that produces thrust by expelling propellant at high speed. Its basic operating principle underlies every era of rocket technology.
Konstantin Tsiolkovsky: A Russian and Soviet scientist who derived key principles of rocket flight and space travel. His mathematical work showed how rockets could reach space.
V-2 rocket: A German ballistic missile developed during World War II and the first human-made object to reach the edge of space. It demonstrated large-scale liquid-fueled rocket performance and shaped postwar programs.
Ballistic missile: A missile that follows a largely ballistic trajectory after powered flight. Military rocket development produced long-range ballistic weapons alongside space launchers.
Fire arrow: A projectile propelled or assisted by a gunpowder charge, used in early Chinese warfare. Fire arrows were among the earliest forms of military rocket.
Tsiolkovsky rocket equation: An equation relating a rocket's velocity change to exhaust velocity and the mass ratio of vehicle and propellant. It quantifies why staging and efficient propellant became central to reaching space.
Robert H. Goddard: An American physicist who developed and launched the first liquid-fueled rocket in 1926. His experiments established practical liquid-propellant rocketry.
Sputnik 1: The first artificial satellite, launched by the Soviet Union on October 4, 1957. Its launch began the space age and demonstrated orbital launch capability.
Space Race: The Cold War competition between the United States and Soviet Union to achieve milestones in spaceflight. Rocket capability became a visible measure of national power and technical capacity.
