How much do astronauts get paid?

I'm curious, could you elaborate on the salary structure for astronauts? Are there any notable differences in pay between missions to the Moon, Mars, or other celestial bodies? Are there bonuses or incentives for completing certain tasks or missions? Additionally, how do their salaries compare to other highly skilled professions, such as physicians or engineers? It would be fascinating to understand the compensation packages offered to these brave individuals who embark on such daring missions.
