ISRO Chief Announces: Chandrayaan-4 Parts to Unite Above Earth!

ISRO Chairman S Somanath on 26 June 2024 Wednesday , it was revealed that the ambitious Chandrayaan-4 mission, aimed at returning lunar samples to Earth, will adopt a novel approach to space exploration. Unlike traditional missions where a spacecraft is launched in a single piece, Chandrayaan-4 will see its components sent into orbit in two separate launches.

Groundbreaking strategy involves assembling the spacecraft in orbit, a complex procedure that underscores ISRO’s advanced capabilities in space engineering. Once the assembly is complete, Chandrayaan-4 will then set off on its voyage to the Moon. Method not only optimizes the launch process but also paves the way for more intricate and ambitious space missions in the future.

To launch the spacecraft in parts and assemble it in space is a testament to the innovative spirit and technical prowess of ISRO. It also highlights the meticulous planning and precision required for such a complex task. Successful execution of this plan will mark a new chapter in lunar exploration and further solidify India’s position in the arena of space exploration.

Chandrayaan-4: Leap Beyond Limits

Innovative Assembly in Orbit

Chandrayaan-4 is set to break new ground as it is expected to exceed the carrying capacity of ISRO’s most powerful rocket. To overcome this, ISRO plans to launch the spacecraft in parts and assemble it in space, a first-of-its-kind endeavor in space exploration.

Space Docking: New Frontier

International Space Station was constructed through the assembly of various parts in orbit. Similarly, Chandrayaan-4 will follow this model, marking a pioneering step in spacecraft launch and assembly techniques.

Multiple Launches for Moon Mission

ISRO Chairman S Somanath revealed that Chandrayaan-4 would be launched in multiple phases due to the current limitations of rocket capabilities. Strategic approach will involve space docking capabilities, both in Earth’s orbit and lunar orbit.

Spadex: Demonstrating Docking Prowess

Upcoming Spadex mission is crucial as it will showcase ISRO’s newly developed docking capabilities. Mission will serve as a precursor to the complex maneuvers required for Chandrayaan-4’s lunar journey.

Routine Maneuvers with Innovative Twists

While docking maneuvers are common during lunar missions, Chandrayaan-4 will introduce a novel aspect by performing docking operations in Earth’s orbit, a feat not yet claimed by any other space agency.

Vision 2047: India’s Space Ambitions

Chandrayaan-4 mission is part of ISRO’s Vision 2047, which includes ambitious projects like building India’s own space station, Bharatiya Antariksh Station (BAS), and sending humans to the Moon by 2040.

Launching Bharatiya Antariksh Station

First segment of the BAS is planned for launch by 2028 using the current LVM3 rocket. Marks the beginning of a series of launches that will eventually lead to the establishment of India’s space station.

Developing the Next Generation Launch Vehicle

Future modules of BAS may be launched using an upgraded version of LVM3 or the Next Generation Launch Vehicle (NGLV), which is currently under development. NGLV represents the next step in India’s space launch capabilities.

NGLV: Designing the Future

Full design and production plan for the NGLV has been prepared, encompassing its configuration, architecture, and cost. Comprehensive plan will soon be presented to the government for approval.

Expanding Infrastructure for Heavier Rockets

To accommodate the larger and heavier NGLV, ISRO is developing a new launch complex. This facility will be equipped to handle the demands of launching a 4,000-ton rocket, setting the stage for more advanced space missions.
