India's ambitious Gaganyaan mission, poised to be the nation's first human spaceflight, is steadily progressing towards its anticipated launch in 2027. The Indian Space Research Organisation (ISRO), under the leadership of Chairman Dr. V Narayanan, is meticulously conducting a series of tests and evaluations to ensure the safety and success of the mission. The human-rating of the launch vehicle, LVM Mk3, and all associated propulsion systems is reported to be nearly 95% complete, signifying a significant milestone in the development process. The crew module, the spacecraft designed to house the astronauts, is currently undergoing final stages of testing and qualification, a critical phase to validate its functionality and reliability in the harsh environment of space. Before sending astronauts, ISRO will launch three un-crewed orbital test flights to showcase end-to-end demonstration. These un-crewed missions will carry a robotic payload called Vyomitra and ISRO is targeting a year-end launch for the first mission, with subsequent launches planned every six months. This phased approach allows ISRO to meticulously assess the performance of all systems and address any potential issues before risking human lives. The mission's groundwork is accelerating as the first uncrewed orbital flight is planned later this year. It will be followed by more missions every six months. The development of the environmental control and life support system (ECLSS) is also in its final phase, requiring extensive testing and qualification. This system is crucial for maintaining a habitable environment for the astronauts, regulating temperature, pressure, humidity, oxygen, and carbon dioxide levels within the crew module. Maintaining these parameters may seem simple but in engineering terms it is a complex task, requiring thousands of control components. Given the inherent risks associated with human spaceflight, ISRO places paramount importance on crew safety. A crew escape system, powered by high-thrust solid motors, is being developed to ensure the astronauts' safe extraction from the launch vehicle in the event of an emergency. The crew module will also face intense heat reflux and temperature rise during re-entry, so that requires a robust thermal protection system. Ensuring the astronauts' well-being extends beyond the technological aspects. ISRO is also focusing on human-centric activities, including the development of specialized space food, medical kits, and other life support essentials. Furthermore, the safe return of the crew to Earth is a key consideration, with plans in place for a parachute-assisted splashdown in the sea. Nine parachutes are required for their safe splash down in the sea. Beyond Gaganyaan, ISRO is also participating in the Axiom Mission-4, which will send Group Captain Shubhanshu Shukla to the International Space Station (ISS). This mission provides valuable opportunities for ISRO to gain experience in human spaceflight operations, conduct experiments in a space environment, and learn how to work effectively in a hostile space environment. The mission will bring lots of data for ISRO and be advantageous for Gaganyaan, particularly in training and operational aspects. ISRO is also planning more space-docking missions. The Chandrayaan-4 mission, a sample return mission to the Moon, will require two separate modules to dock in space. The Bhartiya Antriksh Station will need five modules to dock in space. Space docking is crucial for these missions. This capability is also essential for future missions such as the Bhartiya Antriksh Station, India's proposed space station, which will require multiple modules to dock together in orbit. Space docking involves two satellites travelling at 28,000km/hour velocity and requires tough cameras, precise algorithms, advanced propulsion and inertial systems. SpaDeX, a mission to successfully dock, was successfully tested with some problems and further attempts in April with energy transfer went well. ISRO is also planning a second SpaDeX Mission, which will have the actual configuration required for our future missions. ISRO's accomplishments are a testament to its growth and capabilities. Currently, ISRO has 55 satellites operating in space, with plans to increase this number to 155. ISRO has accomplished exponential growth and many missions over the past 60 years. In addition to human spaceflight, ISRO is also pursuing other ambitious projects, including the Venus Orbiter Mission and Chandrayaan-4.
