The planet Mercury is the smallest and innermost planet in our solar system. It is named after the Roman god of commerce, speed and travel.

Mercury has a diameter of only 0.387530 km, but it is quite interesting and fun to study.

The only rocky object in the Solar System other than Earth, it has long been considered a very challenging target for space exploration. One factor that makes studying the planet so difficult is its eccentric orbit; Mercury’s distance from the Sun ranges from 100 million kilometers at perihelion (closest approach) to 140 million kilometers at aphelion (furthest point away).

Scientists are planning a series of missions to Mercury over the next several years. The first will be launched in February 2021, with two more missions following in 2022 and 2023. These missions will use spacecrafts capable of traveling around the inner Solar System, providing unprecedented views of Mercury’s surface and its magnetic field.
But there is some limitations…..
With low gravity and extreme temperature variations in the atmosphere, landing on Mercury could only be attempted by spaceships with large wings. Moreover, the planet’s surface is scorching hot with an average temperature of +430 degrees Celsius – an area so hot even spacecrafts with landing jets would be sent flying away from it.

A team of scientists has come up with a possible plan to attempt a landing on Mercury, the planet closest to the sun. The mission would take six years and would require the craft to be slowed down by braking using water electrolysis at high speeds. The mission would also need a special trajectory that brings the craft down slowly and steadily.

Flying towards Mercury with a compound of hydrazine and nitrogen tetroxide, you could stop the spacecraft’s speed by water electrolysis, allowing it to orbit the planet. This process would also allow scientists to examine an area of the planet that is so hot and low in gravity it can only be reached by spaceships with large wings.
