How much fuel do you need to get to Mercury?

The amount of fuel required to reach Mercury depends on the spacecraft's design, mission profile, and trajectory. Generally, a mission to Mercury involves multiple gravity assists, often from Earth and Venus, to reduce fuel consumption. For example, the MESSENGER mission used about 4,000 kilograms of propellant during its journey, which included several flybys. Overall, precise fuel requirements can vary significantly based on mission specifics and spacecraft capabilities.
