After scripting history last year with the success of Chandrayaan-3, ISRO is set for its next big mission-Gaganyaan. The nearly Rs 9,000 crore mission will be India's first human space flight program,and it will take four astronauts as part of the Gaganyaan mission-Group Captain Prasanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap and Wing Commander Shubhanshu Shukla.
As all eyes get set on ISRO¡¯s next big mission Gaganayaan this year, let us have a look at all of its?upcoming major missions and their expected costs:
Expected launch year: 2024
NASA-ISRO SAR (NISAR) is a low-earth orbit (LEO) observatory being jointly developed by NASA and ISRO. In just 12 days, NISAR will map the whole planet, offering spatially and temporally consistent data that will help us comprehend changes in Earth's ecosystems, ice mass, biomass of vegetation, sea level rise, groundwater, and natural hazards like volcanoes, landslides, tsunamis, and earthquakes.
According to ISRO, both agencies would make significant contributions to this flagship partnership. The L-Band SAR payload system is being provided by NASA, and the S-Band SAR payload by ISRO. A large common unfurlable reflector antenna, with a diameter of approximately 12 meters, will be used by both of these SAR systems. NASA would also supply engineering payloads for the mission, such as GPS receivers, a solid-state recorder, a high-rate science downlink system, and a payload data subsystem.?

Expected launch year: 2024
With a range of applications in human spaceflight, in-space satellite servicing, and other proximity operations, ISRO is developing the twin spacecraft mission known as SPADEX, or Space Docking Experiment, to mature technologies related to orbital rendezvous, docking, formation flying, and other proximity operations.
Two IMS-class (200 kg) satellites, named Chaser and Target, would be launched as co-passengers or auxiliary payloads as part of the SPADEX campaign. It would inject both spacecraft into slightly different orbits. Currently, a Polar Satellite Launch Vehicle is set to launch the Space Docking Experiment from Satish Dhawan Space Centre.?
Expected launch year: 2028
India's Union Minister of Science and Technology, Jitendra Singh, stated in February 2024 that the Indian Space Research Organisation (ISRO) is constructing India's first space station, to be named Bharatiya Antariksh Station (BAS), gradually by the year 2035.
With the plan currently in the "conceptualization phase," where the overall architecture, quantity, and types of modules that are needed for the station have been studied and identified, ISRO is working to establish Bharatiya Antariksh Station, India's own space station.
This preliminary model of the station is expected for establishment by 2028, with developmental tests beginning as early as in next year, i.e. 2025. Then, the larger, final version of India¡¯s own space station is expected to complete by 2035.
Expected launch year: 2024
India's first-ever human space mission, Gaganyaan, is scheduled to launch in 2024. The final human space flight, known as the "H1 mission," is scheduled to launch in the fourth quarter of 2024 or early 2025. The second unmanned mission, known as the "G2 mission," will launch in the second quarter of 2024.?
Expected launch year: 2031
P. Sreekumar, the Satish Dhawan Professor at ISRO and advisor to its space science program, stated earlier in the year that the launch of ISRO's Venus mission, known as Shukrayaan I, is scheduled for December 2024. In 2012, the concept was first conceived, over ten years ago.
There is one ideal window for launching from Earth to Venus every nineteen months. Because of this, ISRO has "backup" launch dates in 2026 and 2028 in case it loses out on the 2024 window. However, there are even more ideal windows that occur every eight years and even lower the amount of fuel needed at liftoff.
