Sidusrakkueset, or "space rockets," refer to the vehicles designed for launching payloads into space. These rockets are essential for space exploration, satellite deployment, and scientific research. They operate by expelling mass at high velocity through a process known as rocket propulsion, which generates thrust according to Newton’s third law of motion.

The development of rockets began with early experiments in the 19th century, but modern rocketry emerged in the 20th century. Key milestones include the German V-2 rocket during World War II, the Soviet Sputnik launch in 1957, and NASA’s Apollo missions in the 1960s and 1970s. Today, rockets are used by space agencies like NASA, Roscosmos, ESA, and private companies such as SpaceX, Blue Origin, and Rocket Lab.

Rockets are typically composed of multiple stages, where each stage is jettisoned once its fuel is expended, improving efficiency. They are powered by various propulsion systems, including liquid-fueled engines (using fuels like kerosene or hydrogen) and solid-fueled rockets. Some advanced designs incorporate reusable components, reducing costs and environmental impact.

Sidusrakkueset play a critical role in space missions, including crewed flights, orbital deployments, and deep-space probes. Challenges in rocket technology include ensuring reliability, minimizing launch costs, and developing sustainable propulsion methods. Ongoing innovations aim to improve performance, safety, and accessibility to space exploration.
