Space Launch Vehicles (SLVs) are powerful rockets designed to transport payloads, such as satellites or scientific instruments, from Earth's surface into space. They work by generating thrust through the combustion of fuel, allowing them to overcome Earth's gravity. SLVs come in various sizes and configurations, depending on their intended mission and payload capacity. These vehicles typically consist of multiple stages, each designed to operate at different altitudes and speeds. Once a stage completes its burn, it is jettisoned to reduce weight, allowing the remaining stages to continue the ascent. Notable examples of SLVs include the SpaceX Falcon 9 and the NASA Space Launch System (SLS).
