Why are countries keen on developing their own space stations? What obstacles do they face in the process and how can these be overcome?

Reasons for countries keen on developing space stations: (1) Rise in space exploration missions and satellite networks. (2) Emergence of space warfare among nations. (3) Uncertainty in cooperation, collaboration among countries for space missions. (4) Space has become a competitive environment globally. (5) Necessary for maintaining national

supremacy in geopolitical scenario. (6) Essential for maintaining national security and protection of national satellite system. (7) Increased restrictions on usage of international space station. Obstacles faced in the process: (1) Technology acquisition for development of space station. (2) Dependence on launch vehicles of other countries to transport space products. (3) Threat of space pollution due to multiple space stations. (4) Impending threat of Kesslers Syndrome. (5) Protectionist attitude towards manufacturing of space units. (6) Lack of trained astronauts for the space stations. (7) Huge fiscal costs in maintenance and operation of space station. Measures to overcome the obstacles: (1) Formalisation of space regulation to curb space pollution. (2) Codification, agreements to treat space as a global common resource. (3) Information dissemination, technology sharing in constructing of space station. (4) Employment of reusable space units (e.g. SPADEX docking system). (5) Region groups to be prefabricated for space stations than individual countries. (6) Global training programs for astronaut.

The Bharat Antariksh Mission is a step is right direction by India to achieve the goal of Indian space station.
