Chandrayaan-3's Moon Landing: Collaborative Efforts of NASA and ESA with ISRO

On August 23rd, all eyes will be turned towards the lunar surface as India's Vikram Lander, part of the Chandrayaan-3 mission launched by the Indian Space Research Organisation (ISRO) on July 14, attempts a historic lunar touchdown. This mission has captured global attention, not only because of India's endeavor to achieve a lunar feat but also due to the collaboration between ISRO and international space agencies, notably NASA and ESA, in ensuring its success.

A Shared Endeavor

The significance of Chandrayaan-3's mission extends beyond national borders, as it embodies the spirit of international cooperation in space exploration. Among the key contributors to this mission are the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). Although India is taking the lead, the mission is reinforced by the expertise and resources of these foreign space agencies.

NASA's Role and Support

One night wonder how NASA, an American space agency, is contributing to India's lunar mission. Since its launch, NASA has been instrumental in supporting ISRO by monitoring the health and trajectory of Chandrayaan-3. The Deep Space Network (DSN), operated by NASA, plays a pivotal role in this endeavor. The DSN provides telemetry and tracking coverage during the spacecraft's critical powered descent phase. The stations DSS-36 and DSS-34 at the Canberra Deep Space Communications Complex, followed by DSS-65 at the Madrid Deep Space Communications Complex, have been employed to track and monitor Chandrayaan-3's journey, ensuring its safe landing.

ESA's Invaluable Assistance

Beyond NASA, the European Space Agency (ESA) has also played a vital role in Chandrayaan-3's mission. ESA's involvement includes tracking the satellite in its orbit through two ground stations within the ESTRACK network. These stations are equipped to receive telemetry data from the spacecraft and transmit it to the Mission Operations Centre in Bengaluru. Moreover, they facilitate the relay of commands from Bengaluru to the orbiting satellite, streamlining communication between ISRO and Chandrayaan-3.

Crucial Ground Station Support

As the Vikram Lander approaches the lunar surface for its touchdown, the involvement of these ground stations is of paramount importance. To further enhance the mission's chances of success, a third ground station within the ESTRACK network has been established. This station, located at the ESA's 35-meter space antenna in New Norcia, Australia, is tasked with tracking and communicating with the Lander Module during its descent. Serving as a backup to ISRO's own ground station, this additional support guarantees comprehensive coverage of the mission's critical phase.

Milestones Achieved

Recent developments in the Chandrayaan-3 mission have been met with excitement and anticipation. Notably, ISRO has successfully established two-way communication between the Lander Module of Chandrayaan-3 and its predecessor, the Chandrayaan-2 orbiter. This achievement marks a significant step forward, as it opens new avenues for communication and collaboration, enhancing the mission's capabilities and resilience.

Capturing the Unseen: Far Side of the Moon

In a fascinating move, ISRO released images of the far side of the lunar surface captured by Chandrayaan-3's Lander Hazard Detection and Avoidance Camera (LHDAC). These images, taken on August 19th, provide a glimpse of the lunar region that is perpetually hidden from Earth's view. The far side, often referred to as the dark side of the moon, adds an air of mystery to lunar exploration, and these images offer a tantalizing preview of the uncharted territory that Chandrayaan-3 seeks to explore.

Conclusion: A Unified Journey to the Moon

The Chandrayaan-3 mission encapsulates the spirit of international collaboration and scientific advancement. With the support of NASA and ESA, ISRO is poised to achieve an extraordinary milestone by successfully landing the Vikram Lander on the lunar surface. The combined efforts of these space agencies demonstrate the power of shared knowledge, expertise, and resources in pushing the boundaries of human exploration. As the world awaits the outcome of this daring endeavor, it is a testament to the unity of purpose that transcends borders and propels us towards new horizons in space exploration.
