For centuries, scientists and researchers have been fascinated by outer space and the mysteries it holds. With the advancement of technology, we have been able to explore space in ways previously thought impossible. One of the most notable outcomes of our space exploration is the establishment of space stations, which have had immense impacts on our understanding of the human body. Space stations give scientists the opportunity to conduct experiments and studies that cannot be done on earth due to the conditions in space. These research studies have led to medical breakthroughs that have benefited humanity significantly. This essay will explore the many ways in which space stations have impacted the study of the human body, highlighting the significant benefits and advancements that have been made thus far.
From Earth to Space: How the Study of Human Biology Evolved with the Launch of Space Stations
Space stations have revolutionized our understanding of human biology. Since the launch of Salyut 1 in 1971, humans have been living and conducting research in space, providing us with unique insights into how our bodies behave in microgravity environments. This article will explore how space stations have impacted the study of human biology and what we have learned so far.
The Early Days: Soviet Union & The United States
The first space station was launched by the Soviet Union in 1971, followed by NASA's Skylab program in 1973. These early missions focused on understanding how humans could live and work for extended periods in space. Scientists monitored changes to astronauts' cardiovascular systems, muscles, bones and eyesight.
Mir & International Space Station (ISS)
The introduction of Mir- a Russian modular spacecraft which orbited Earth from 1986 to 2001 - allowed for longer-duration missions that enabled more rigorous scientific experimentation on human physiology. Researchers were able to observe changes such as muscle atrophy and bone loss that occurred over several months.
The International Space Station (ISS) is a culmination of decades-long efforts between Russia, Europe, Japan and Canada; it has been orbiting Earth since November 1998. It is now considered one of humanity's greatest engineering feats -- a laboratory orbiting above us where scientists can conduct experiments unparalleled on earth.
Cardiovascular System: The Impact Of Microgravity
One area where space stations have significantly contributed to medical science is cardiovascular research. Astronauts can experience significant reductions in their blood volume during long-term stays aboard the ISS due to fluid shifts towards their heads resulting from microgravity conditions; this leads to high blood pressure or hypertension.
To monitor these effects on astronauts' hearts during long-duration flights aboard ISS NASA uses an ultrasound device called Vascular Echo which can detect thickening of the arteries. Additionally, space experiments have provided valuable data for improving treatments for cardiovascular diseases on Earth.
Skeletal System: The Impact Of Microgravity
Another area where space missions have made great contributions is in the study of human skeletal systems. Astronauts living in microgravity conditions lose bone mass at a rate approximately ten times faster than older women with osteoporosis, making them a unique population to study this condition.
Researchers use Dual Energy X-ray Absorptiometry (DXA) scans to measure astronauts' bone density before and after extended-duration missions. This data has helped scientists identify new approaches to prevent and treat osteoporosis on earth.
Muscular System: The Impact Of Microgravity
Living in microgravity conditions also causes significant muscle changes for astronauts aboard ISS; their muscles weaken, shrink or atrophy due to disuse as there is little resistance from gravity. Researchers use exercise equipment such as the Advanced Resistive Exercise Device (ARED) aboard ISS which provides resistance training similar to weightlifting but without weights.
NASA's Human Research Program aims at studying how these changes impact an astronaut's ability to perform tasks during long-term stays aboard ISS; this research has also contributed significantly towards developing novel therapies for muscular degenerative disorders such as muscular dystrophy on earth.
