Qualities Of A Moon Lander

By Melissa Rogers


The moon is known as a place that does not support life and for on to get there they must have a means to get there. The moon lander is usually the spacecraft that is used to carry people into space and back. It navigates through the high altitude. It often increases speed when it comes closes to the celestial body as the gravitational pull of a moon pulls the vehicle to the surface.

As a result of the pull of gravity, the landing speed must be reduced to a minimum level to have a soft landing. The pace is usually reduced to less than 160 kilometers per hour. Any rate higher than this may result in an impact that would kill entire crew on board. The velocity change is usually by the aid of this space lander which is generally carried by the main spaceship.

The force of gravity of these planets is high thus for the ship to leave the ground, the thrust must be very high to be able to resist the pull by the surface of the moon. This ensures that the rocket successfully departs from the plant and reenters the earth using the kinetic energy and reduced speed for a good and 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.

The spacecraft is designed in a way that the interior is protected from the great friction caused by the atmosphere and the body of the probe during reentry into the earth. The command units burst into flames to protect the interior from the heat caused by the friction.

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 journey to a heavenly body is not all that successful as there is an incidence where the space lander has crashed causing the death of everyone on board. This is usually due to failure of the essential parts of a spacecraft. However, since not everyone can make it to the heavenly body, some models mimic the environment of the moon have been developed where all the activities that take place on the planet have been simulated including the spaceship.

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.
