The space station would weigh 52 tonnes and maintain an orbit of approximately 400 kilometres above the Earth, where astronauts could stay for 3-6 months.

[4] Originally planned to be completed by 2030, it was later postponed to 2035 due to delays caused by technical issues related with the Gaganyaan crewed spaceflight mission and the COVID-19 pandemic in India.

Three years later, in his New Year's speech delivered before retiring as chairman, Sivan stated that India's first crewed spaceflight project Gaganyaan had completed the design phase and entered into the testing phase, hinting that the organization has achieved a breakthrough in reaching the space mission milestone.

This potential partnership could leverage the expertise and experience of both countries, fostering innovation and advancing human presence in space between the two Artemis Accords signatories.

[1][11] The chairman of ISRO, S. Somanath revealed that he had been reviewing the designs of the Indian Space Station when speaking with media during India International Science Festival 2024.

ISRO is planning to establish a basic, preliminary model of the space station in 2028 before building the larger, final version in 2035.

[12][13] In addition to offering insights into India's Space Vision 2047, S. Somanath on 26 October 2024, presented the idea of Bharatiya Antariksha Station serving as a base for lunar exploration on Sardar Patel Memorial Lecture.

Hardware requirements and more unmanned flights are part of this expansion, which is meant to supplement the continuing human spaceflight programs.

[12] The establishment of the Bharatiya Antariksha Station is poised to enhance India's presence in space research and exploration significantly as it will provide a unique platform for conducting scientific experiments in microgravity and foster advancements in space technology, potentially leading to economic activities based on lunar resources 2047.

According to the existing blueprints, the Bharatiya Antariksha Station would be powered by two sizable solar panels in the initial phase.

[20] In June 2024, S Somanath informed NDTV about the completion of detailed design work for the space station's Phase-1 module, which is scheduled to launch on LVM3 in 2028.

[23][24][25] A polymer electrolyte membrane Fuel Cell Power System (FCPS) created by the Vikram Sarabhai Space Center (VSSC) was successfully launched by ISRO on 1 January 2024, as part of the PSLV-C58 mission.

A project report that includes all the information, a study and internal evaluation, and a cost estimate has been prepared and is about to be approved by the government.
