Question

What is the hardest part of space travel?

Answer 1

Hint:There are a few factors that make space travel hard. For example, the bulky suits that astronomers have to wear to walk in space or the air that can cause many underlying medical issues or the temperature change. To overcome these difficulties effort, tedious work, and training are required. These all factors make it difficult for space travel.


 Complete step by step solution:
There are a few factors that make space travel hard. Some of them are walking in space, gravity’s drag, medical issues, landing, and temperature.
One of the challenging parts of space training is how to use a spacesuit. As these suits are made bulky to protect the wearer from the environment while walking in space, the body movements become tedious and awkward.
The next challenging issue is gravity's drag. To escape from the gravity’s pull, it must attain a speed that is greater than $25000\text{ mph}\text{.}$
Another issue of space travel is that the particles travel towards the astronomers at the speed of light. In addition, the air in space can cause issues such as cataracts, cancer, and Alzheimer’s.
After space travel, landing back on the earth becomes difficult as crashing is not a suitable option.
Another main danger that occurs in space temperature. It can be freezing in the shadow (not in the line of sight of the sun) or extremely hot when it is in the line of sight of the sun.

Note:In the above passage, we have discussed some of the difficulties of space travel. Difficulties such as walking in space or traveling at a certain speed to escape the gravity drag or the medical issues that these astronomers have to face or the issue related to landing back on Earth and also the varying extreme temperatures.
