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.
The speed of landing on the heavenly body must be put in check as a result of this gravitational pull. This is to ensure that there is a soft landing of the spacecraft. If the speed is not maintained below 160 kilometers per hour, then there is a high chance that the impact would kill all the persons on board.
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 upper segment of a module is lifted by the ascent engine from the surface of this heavenly body, attaching to the revolving command units. The engineer always ensures that the engines are functioning well to ensure that the astronauts are not stranded in any way. The engines use a liquid fuel such as hydrazine are used to provide the high thrust power when leaving the surface of a planet.
Reentering the earth is usually very violent, and the spaceship is designed in a way that the interior is protected. Pieces of flaming command units are experienced and as the sheep pass through the atmosphere towards from the ground. The burning materials were designed to cause flame so that by burning away they shield the interior of a ship from the heat from the friction of atmosphere and the spacecraft.
Due to the fear of alien microbial agents the astronauts wear protective gear to minimize the spread of these microorganisms that they may have acquired through their walk on space. If these foreign biological agents exist, they may cause incurable diseases since they are foreign. For this reason, they wear the garments until they get to quarantine. However, the ground of this plants has no sign of life hence this process of quarantine is sometimes unnecessary.
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.
With the advancement in technology, more tests on the exploitation and navigation into space are being carried out, and more advanced spaceships are being developed not only to explore the planets but also to explore other planets such as mars.
