In the realm of modern aerospace exploration, the growing issue of space debris poses a significant challenge for countries involved in space research and missions. To address this problem, interdisciplinary efforts are underway to find solutions and conduct research aimed at reducing the risks associated with space debris. This paper presents a foundational study for a larger research project focused on developing a femtosatellite model tailored for studying thermal atmosphere dynamics, with the ultimate goal of addressing various space debris issues. As concerns about space debris continue to rise, femtosatellites are seen as valuable tools for monitoring and understanding how debris behaves in low Earth orbit (LEO). The term "thermal atmosphere" refers to the layers of gases surrounding a celestial body, such as Earth's atmosphere. Space debris, including defunct satellites and spent rocket stages, interacts with these atmospheric layers, especially in the upper atmosphere, where phenomena like drag and heating during reentry occur. Femtosatellites, also known as femto spacecraft, are small satellites weighing just a few hundred grams. Due to their compact size and low cost, they are ideal for conducting specific scientific experiments and educational activities. Equipped with sensors, accelerometers, and GPS, femtosatellites can gather data on atmospheric density as they orbit Earth, providing precise measurements of the thermal atmosphere at different altitudes. This helps us understand atmospheric dynamics and their impact on objects in space, offering valuable insights for managing space debris during reentry events. In conclusion, this paper underscores the promising potential of femtosatellites in advancing our comprehension of space debris dynamics, offering practical solutions to mitigate associated risks. Furthermore, we are thrilled to present a pioneering design concept for a femtosatellite optimized for measuring thermal atmosphere conditions. By prioritizing lightweight construction and cost-efficiency, our proposed design aims to democratize access to atmospheric research, fostering collaboration and innovation in the scientific community. We anticipate that this endeavor will not only enhance our understanding of Earth's climate but also contribute to the development of sustainable space exploration practices. We look forward to further discussions and collaborations in pursuit of these ambitious goals.
