We have been sending mankind to space for quite a while now. Thy have helped us discover many things, while there are a lot of positive things we gain from their missions, they have to go through some loss for the mission. Muscle loss was a health concern for Astronauts going on short and long term space missions. We wanted to find out the extent of muscle loss in relation to the duration of the mission. We asked, how much muscle loss would occur after 8 days of weightlessness? We discovered that even during short space missions the human body can still experience moderate muscle loss. Each Astronaut had to have an MRI before and after each space mission. Before they came to the conclusion they did, they found out from someone else that Astronauts

File one Summary: Skeletal muscles are made out of striated subunits called sarcomeres, which are made out of the myofilaments actin and myosin. Skeletal muscles contain myofibrils. Every myofibril is striated with dull and light bands. I bands contain just thin fibers, made fundamentally out of actin.

The data does not support the students hypothesis because it was incorrect. A possible explanation for these results is when you exercise your blood starts flowing throughout your body which causes the muscles to move faster and the amount of clothespin squeezes to increase. When a person exercises the blood flow of the person increases. When the blood flow increases, the person's level of oxygen also increases and then, when oxygen is delivered to the muscles a process called anaerobic respiration occurs. When you rest, not a large amount of oxygen is getting to your muscles which leads to the increase of lactic acid, and the lactic acid causes your muscles to fatigue.

On the northern slope of Hawaii's Mauna Loa Volcano, six scientists have been living as though they are inhabiting Mars. The reason; to see if the diet they are on will be enough for a real astronaut to survive on. For four months, Hawaii Space Exploration Analogue and Simulations (HI-SEAS) participants have been studying how their food supply has effected their energy, weight and of course, their appetites. The mock-astronaut's new diet has resulted in minor weight loss for every member. This, of course, could be from the frequent exercise that the scientists did not partake in while at home.

The individuals were barefoot and wore light clothing for height and body weight measurements to ensure accuracy. The body mass index was calculated by dividing the individual's body weight by their height squared. The length of the arm and torso were measured to the closest 0.5 cm to calculate the skeletal muscle mass. This can be found using an integrated bio-impedance equation: skeletal muscle mass in kg = [0.401 × (height in cm²/resistance in Ω) + (3.825 × gender, for men the gender value is 1 and for women it is 0) − (0.071 × age in years) + 5.102] according to a Janssen et al.

These life-science missions have included experiments involving human astronauts, as well as many animals, and even insects. Over the past 50 years, American and Soviet scientists have taken advantage of the animal world for testing. Despite many losses, these animals have taught the scientists a tremendous amount more than they could have learned without them. Without the use of animal testing within the human space program, it is said, the Soviet and American programs could have suffered great losses of human life.

Humans begin to rapidly lose muscle mass due to the fact that space has zero gravity. Muscle loss in space is incredibly dangerous because it also means a reduction in physical strength, which may be necessary during dire emergencies. Humans are able to maintain muscle strength on Earth because they are constantly forced to withstand Earth’s gravitational pull, keeping muscles strong and intact. In a zero-gravity environment, the muscles no longer have to resist gravity (because there is none!). The result is loss in muscle mass.

Have you ever decide to skip your daily routine and try something different for 30 days? This would improve your life and motivate you to try something different constantly. I decided to challenge myself and try something different for 30 days. In my challenge for 30 days, I decided to go every day to the gym. My purpose to go the gym every day is to have an impact on my muscles, maintain a balance diet, and have a daily routine to follow.

Space has helped hone the skills of scientist. By using satellite technology for space, they were able to use the same concept for Earth. Even with all the benefits of space, its major down falls are cost, risks, and low chances of reward for their efforts. Many space explorations cost fortunes with little to come out of it, making it almost seem not worth it. The risk is another key factor, with little known about the majority of space, many outliers can appear out of nowhere and can cause death to anyone that happens to be working up there.
