Effects of Space on Living Organisms

Space holds a myriad of challenges that can significantly affect living organisms, necessitating extensive research to understand these effects and devise protective measures. One prominent area of inquiry pertains to the impact of altered gravitational forces and heightened radiation levels experienced during space travel. Microgravity, a condition where gravity is significantly weaker than on Earth, can lead to severe physiological alterations such as muscle atrophy and bone density loss. NASA has been at the forefront of studying these effects to ensure the health and safety of astronauts on extended missions [2](https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html#:~:text=In%20the%20absence%20of%20gravity,as%20they%20do%20on%20Earth.).

Moreover, Dr. Sharmila Bhattacharya, a leading NASA scientist, has been utilizing model organisms like fruit flies and yeast to investigate the biological effects of space conditions. Her research is pivotal in enhancing our understanding of how gravity and radiation impact cellular and molecular processes [1](https://www.livemint.com/mint-lounge/ideas/nasa-scientist-sharmila-bhattacharya-axiom-space-mission-india-11749802010076.html). Findings from these studies reveal that space conditions can weaken the immune response, as observed in fruit flies, drawing attention to the need for effective countermeasures to safeguard astronaut health [6](https://www.nasa.gov/podcasts/nasa-in-silicon-valley/sharmila-bhattacharya-on-studying-how-biology-changes-in-space/).

Radiation, another critical concern in space exploration, poses a significant risk to the health of astronauts by increasing the potential for cancer and causing damage to the central nervous system [3](https://www.nasa.gov/analogs/nsrl/why-space-radiation-matters/#:~:text=The%20risks%20of%20radiation%20exposure,degenerative%20tissue%20and%20central%20nervous). Understanding the extent of these risks is crucial for developing protective strategies that ensure the well-being of crew members during deep-space missions, such as those envisioned in NASA's Artemis program [2](https://www.nasa.gov/what-is-artemis/).

Beyond the confines of laboratory research, collaborative efforts are underway to translate these insights into practical solutions. Dr. Bhattacharya plays a key role in fostering collaborations that span various countries and organizations, which are essential for addressing the multifaceted challenges of human spaceflight.
