Why Is Mercury So Difficult for Spacecraft to Visit?

This documentary explains why Mercury, the innermost planet, is one of the hardest targets in the solar system for spacecraft to reach. It sets the challenge against the wider rise of commercial spaceflight and the dream of routine travel beyond Earth. Through orbital mechanics and mission history it shows the enormous effort needed to visit a world so close to the Sun. It is a clear, rewarding watch for anyone curious about space exploration.
