Just like any challenge, the winner would get bragging rights for the rest of their life. After Russia got into orbit around the Earth first and technically won, the US decided that they should go again to see who could get farther, because getting into orbit was just an elementary achievement. After the United States were the first to land on the moon, there was a full blown space war going on, with an everlasting list of firsts being achieved by either: the first woman, the first spacewalk,…

    Spaceflight Osteopenia (Bone Atrophy) Spaceflight osteopenia refers to the reduction in bone density that occurs during space travel. The depletion of bone mass experienced by astronauts could weaken the bones and is a consequential side effect of extended spaceflight. This could present critical problems when the astronauts return to a weight-bearing environment such as the Earth. Researchers speculate the number one cause of bone atrophy in space is weightlessness, where both the astronauts…

    Scott et al. compared those who suffer from spinal cord injury (SCI) and the body under microgravity. Their findings show that SCI patients and astronauts, in long term conditions, have similar physiological outcomes and those who have SCI can be good examples to study the effects of spaceflight on the human body. The importance of comparing and contrasting these two populations is to be able to see if scientists can test individuals of one group to come up with results and conclusions of how to…
