Difficult of living on Mars

         Mars is one of a planet on the outer space that many scientists are wondering to traveled there by spacecraft.It located out of the Earth and to reach there only able to do by astronaut.There are four challenges  on Mars that scientists deal with such as,gravity,weather,food or water and oxygen.

         

          We feel better doing activities every day and every time well without obstacle because we have a gravity on earth,so we can able to balance our body and move in do some work or even do some exercise.People feel  afraid to travel Mars because there is no gravity on the Mars.Many scientists are take a risk about this challenge and keep fight for  do their  research on the Mars.It has a weaker  gravity than earth thats why if a person weighing 100 pounds on earth would weigh just 38 pounds on the Mars because there is zero gravity even weak.

          

         The situation on the Mars is different than on the earth because of the weather is extremely cool  lower  111 degrees Celsius and its farther from the sun.To be honest,many astronauts can able to go there without wear some body protection for example, spacesuits,pressurized vehicles and airtight shelters to survive on Mars.

          In fact,there is no any plants grow on the Mars and no water too.scientists  said that there is no life on the Mars because there  is no  any grocery stores or fast food restaurants,so astronauts  must prepare everything for their supplies for instance,they have to prepared all foods and water that will they consume it on the Mars while doing research.

           Oxygen is most important for human life, if you do not get an oxygen for 15 to 20 minutes without breathing air you will die.The travelers have to prepare and provide all space equipments before they travel to the space,so the one important thing is oxygen.They get many oxygen that they need and it must be enough for them during on the Mars.In addition,they have to get 95 percent of carbon dioxide,78 percent of nitrogen,21 percent of oxygen and 0,035 percent of carbon dioxide,if they prepare all of these things for their mission on to the it will be better.
