Next Stop, Moon: Heroes Circling Lunar Wonders!
Key Takeaways
- ISRO’s Chandrayaan-4 will be India’s first mission to bring back Moon samples.
- The complex mission involves two separate rocket launches and in-orbit docking.
- It aims to master critical technologies for deep space exploration.
India is gearing up for its most ambitious lunar mission yet. The Chandrayaan-4 mission, planned by the Indian Space Research Organisation (ISRO), aims to land on the Moon, collect soil and rock samples, and return them to Earth.
A Two-Phase, Two-Launch Strategy
ISRO Chairman S Somanath detailed the mission’s complex architecture. It will be executed in two phases using two separate launch vehicles.
- First Launch: Will carry the propulsion, descender, and ascender modules.
- Second Launch: Will deploy the transfer module with the Earth-return capsule.
“The two modules will dock in Earth orbit, and then proceed to the Moon,” Somanath explained. Mastering this in-orbit rendezvous and docking is a primary technological goal.
The Lunar Sample Return Sequence
Once the combined spacecraft reaches the Moon, a precise sequence of events will unfold:
- The descender module lands on the lunar surface.
- It collects soil and rock samples.
- Samples are transferred to the ascender module.
- The ascender lifts off and docks with the waiting transfer module in lunar orbit.
- Samples are moved to the Earth-return capsule.
The capsule will then journey back to Earth, re-enter the atmosphere, and land safely, likely in the Indian Ocean.
Significance and Roadmap
Somanath stated the mission will showcase India’s advanced capabilities in deep space exploration, sample return, and complex orbital operations. The design prioritises cost-effectiveness for this highly challenging objective.
While an official timeline is pending, Chandrayaan-4 is a cornerstone of ISRO’s future plans, building on the successes of and the Aditya-L1 solar mission.
