Payload Mass
Payload Mass refers to the total weight of the cargo or equipment that a spacecraft carries into space. This includes all the scientific instruments, communication equipment, and other materials that are required for a mission. Payload Mass is a critical factor in determining the launch vehicle and the trajectory of the spacecraft. The payload mass is limited by the capacity of the launch vehicle and the amount of fuel required to reach the desired orbit. The payload mass can vary greatly depending on the mission objectives, ranging from a few kilograms for a small satellite to several tons for a manned mission to the Moon or Mars.
