A Heavy Lift Launch Vehicle (HLLV) is a type of rocket designed to carry large payloads into space. These vehicles are essential for missions that require transporting heavy satellites, scientific instruments, or even crewed spacecraft. HLLVs are capable of delivering payloads that exceed 20,000 kilograms to low Earth orbit, making them crucial for both commercial and governmental space endeavors. Examples of HLLVs include the Space Launch System (SLS) and the Falcon Heavy by SpaceX. These rockets are engineered with multiple engines and stages to provide the necessary thrust for lifting heavy loads. Their development plays a significant role in advancing space exploration and satellite deployment.
