The book is Space Debris .. In 2 kn. Kn. 1. Observation methods and models of space debris" is a fascinating and in-depth study of one of the most pressing problems of our time, written by a team of authors, each of whom is an expert in his field. In the first book of this two-volume edition, attention is focused on observation methods and models of space debris, making it an indispensable source of information for researchers, students and anyone interested in space technology and the ecology of space. Space debris is not just an abstract problem, it is a real threat to satellites, space stations and future missions. The book discusses in detail various aspects of this problem: from the sources of space debris to the methods of its observation. The authors offer the reader a unique look at how modern technologies can help in monitoring and analyzing the situation, as well as in developing effective strategies to minimize the risks associated with space debris. Who can like this book? First of all, it will be of interest to students and graduate students studying astronomy, physics, engineering and ecology . It will also be evaluated by researchers and specialists in the field of space technology, who are looking for up-to-date information on the state and prospects of solving the problem of space debris. In addition, the book can attract the attention of a wide audience interested in space and its exploration, as well as those who want to understand how human activity affects the environment in space. The topics raised in the book are of vital interest and are important for the future of humanity. One of the key topics is the need to develop sustainable methods of space debris management, which is becoming increasingly relevant as the number of satellites and space objects in orbit increases. The authors emphasize that without proper control and monitoring, we risk facing catastrophic consequences that can affect not only space missions, but also life on Earth. The style of the authors is distinguished by scientific rigor and accessibility of the presentation, which allows even an unprepared reader to understand complex concepts. They use many examples and illustrations, which makes the material more clear and understandable. The team of authors includes leading specialists whose work is already known in scientific circles. Their previous publications and research in space technology and ecology make this book particularly valuable. If you are looking for books on space, ecology or technology, then Space Debris will be a great addition to your library. It will not only expand your knowledge of the challenges facing humanity in space, but will also inspire you to think about how we can save our planet and its surroundings for future generations. Reading this book is not just about getting information, it’s an opportunity to be part of an important dialogue about the future of space exploration and humanity’s responsibility to the universe.
