Throughout the history of lunar exploration, more than half of all missions have failed; some have been lost upon landing and never found, others have crashed into the lunar surface, destroying themselves, and others never arrived, so why is it so difficult to land on the Moon?
Why didn't the astronauts on the Apollo missions have these problems? Let's find out!
Although the Moon is one of the closest celestial bodies to Earth, landing on its surface remains a significant challenge for aerospace engineering.
The first factor complicating the Moon landing is its surface. Unlike other planets like Earth, which have a dense atmosphere that can slow down the spacecraft and allow it to land smoothly, the Moon has no significant atmosphere that can be used to slow down the descent. In addition, its surface is covered with craters and rocks, which increases the risk of the spacecraft crashing.
Another major cause of failures in missions to the Moon is lunar gravity, which is only about one-sixth of Earth's gravity. This means that any spacecraft landing on the Moon must be able to decelerate enough to avoid crashing, but it must also calibrate the rocket braking process well to not jump back into space. In other words, the spacecraft design and landing system must balance the need for smooth deceleration and reduced mass so that the spacecraft can remain on the lunar surface.
