The solar system is particularly hard to explore. Mercury is the hardest when it comes to planets.

The ocean is extremely difficult because of the water pressure but three divers have made the deepest part, the Mariana Trench, including filmmaker James Cameron. At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), over 1000 times the standard atmospheric pressure at sea level.

However several planets are impossible to visit, at this time. On Venus, for example, the temperature at the equator averages around 450 °C (842 °F), higher than the melting point of lead, and the atmospheric pressure on the surface is also at least ninety times greater than on Earth,
