Here are some examples of the weights of different space rockets:
- Small Rockets: Small rockets used for scientific research and satellite deployment can weigh anywhere from a few hundred kilograms (kg) to a few tons. For instance, the Pegasus XL rocket, which is used to launch small satellites into orbit, weighs approximately 18,500 kg (40,785 lbs) at liftoff.
- Medium-Sized Rockets: Medium-sized rockets, often used to launch larger satellites or conduct interplanetary missions, can weigh tens to hundreds of tons. For example, the Falcon 9 rocket, developed by SpaceX, weighs approximately 549,054 kg (1,209,450 lbs) at liftoff.
- Heavy-Lift Rockets: Heavy-lift rockets are designed to carry massive payloads, such as space stations, modules, and large satellites, into orbit. These rockets can weigh hundreds of tons. For instance, the Saturn V rocket, which was used to launch the Apollo missions to the moon, weighed approximately 2,970 tons (6,548,000 lbs) at liftoff, making it one of the heaviest rockets ever built.
- Super Heavy-Lift Rockets: Super heavy-lift rockets are still under development and are planned for missions that require extremely large payloads. These rockets are designed to carry payloads of hundreds of tons or even thousands of tons. For example, the proposed SpaceX Starship, which is intended for Mars missions and other ambitious space projects, is expected to weigh approximately 120,000 tons (264,555,000 lbs) at liftoff.
It's important to note that these weights represent the rocket's mass at liftoff, including the weight of the fuel and payload it is carrying. As the rocket burns its fuel and sheds stages during its ascent, its weight decreases significantly.
