For people to get to the moon, there must be a spacecraft that should leave the gravity of the earth, and this can only be possible using a rocket jet. Unlike other aircraft, a rocket is known to propel through the increasing altitude without any problem in the vacuum which is outside the atmospheric of the earth. When they are closer to a target planet, the moon lander will draw closer to the surface as the gravity pull it causing increasing of speed.
A minimum speed of fewer than 160 kilometers per hour is usually recommended for a successful soft landing on the surface of planets. High speed during landing can result in a crash that may kill every crew member on board as a result of the impact. The rate of landing is controlled by the lunar lander which is usually carried by the main spacecraft.
The spacecraft must have a mighty thrust to evade the gravitational pull of this heavenly bodies so that it may return to earth. Through the energy of motion and the reduction in speed, the rocket leaves space and safely lands on the planet.
The ascent engine plays a vital role on the reentry into the world. The driver lifts the upper section of this lunar module from the surface of this heavenly body and an upper part, and it attaches to the orbiting command units. The engine is highly efficient. Thus the astronauts are often not stranded. When liquid propellants such as hydrazine, a strong and powerful thrust are provided which enables leave the surface of s planet when entering the and leave the ground when going to the moon.
Reentry to earth is also very crucial as it involves a very violent encounter with the atmosphere of earth. The pieces of these ships wear out and usually produce flames as a result of frequent friction. However, the flaming modules are designed for that purpose since they protect the inside the ship from the heat caused by that friction thus those on board are usually safe so long as nothing else goes wrong.
There is also fear of alien biological species of bacteria and virus thus the ship is fitted with protective garments to prevent the spread of these species to earth. They are expected to have these gears on until they get to a 21-day quarantine. However, it has been argued that since the heavenly body does not support life, it is unlikely that the foreign biological agents could be present thus this process of wearing protective gear, isolation, and quarantine is not very important.
Sometimes the missions of landing on the moon have been fatal as the systems fail. Accidents by these vehicles usually leave no survivors. This has necessitated the use of robots for purposes that have little chance of survival. Many have developed models that mimic the space and the lunar lander and have become significant attraction sites.
More advanced machines such as space lenders are being developed not only for the exploration of this moon but also space at large. This is due to the technological advancement in the past two decades.
