Being in space, a person’s body undergoes several changes due to ungravation, such as muscle and bone atrophy, alterations in the circulatory system and the immune system, and vision problems.
To corroborate such information, a NASA study revealed that the bone structure is also deteriorated, he reported 20 minutes.
The observations of the space agency, made in a group of mice sent to the International Space Station (ISS), for 37 days, showed that the femards of these animals were the most affected by microgravity.
According to the data collected by NASA and the Blue Marble Space Institute of Science laboratory, the mice showed structural damage to their posterior limbs.
In addition, the images revealed large internal cavities at the ends of the femur, especially in the areas near the knee and hip joint. However, the lumbar part of the column remained virtually unchanged.
The researchers also explain that “if radiation or a systemic factor were responsible for bone loss, it would be normal to find generalized alterations.”
Therefore, experts concluded that this problem could affect the human being in their next missions to space, since a long -lasting journey would harm those bones with greater weight influence.
It is estimated that the human being loses 1% of its bone capacity for each month in space and, unfortunately, another study indicates that the bone structure is not recovered.
In addition, one of the most worrying discoveries of the study by NASA is that young mice began to show premature ossification, that is, a process in which the cartilage becomes a bone before usual and ends up affecting the future skeletal development.
Therefore, to counteract this situation, now, NASA investigates whether physical exercise or mechanical resistance systems can stop the loss of bone mass into prolonged missions to space.
