The most significant achievement in rocket science is to get a man to the surface of these beautiful heavenly bodies. This has been made possible through the development of robust moon lander which cuts across the increasing altitude as the speed increases. The speed becomes even higher when the spacecraft comes closer to landing on the surface of the moon. This is usually because of gravitational force from the planet.
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.
For scientists to get back on the earth, the speed of a lunar lander must be high enough to prevent the gravitational pull by the gravity well of this heavenly body. After which the rocket leaves the planet and returns to the world through the absorption of kinetic energy and reduction of speed for safe landing.
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.
The spacecraft sometimes fail with people on-board and crash leading to death. Robots have been used at times to minimize this kind of scenario. It is not possible for everyone to have the space experience. Models have been developed that resemble every aspect of the environment of the heavenly body, and these simulations have been 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.
