Multiple rocket stages are necessary in order to get large payloads into space using chemical rockets. This is because as the fuel is burnt, the rocket becomes lighter and therefore needs less thrust to continue accelerating. By staging the rocket, the previous stages can be discarded once their fuel is expended, and the remaining stages can continue accelerating the payload. This allows for larger payloads to be launched into space.
