Race to the Moon’s South Pole: India’s Chandrayaan-3 and Russia’s Luna-25 Compete for Lunar Glory!

As the excitement builds up, India’s Chandrayaan-3 moon mission is rapidly approaching its defining moment. However, it’s not just the scientific aspirations of ISRO that are on board; it’s also the collective hopes and sentiments of India’s 1.41 billion population. The mission is all set for its dramatic lunar touchdown at the moon’s South Pole, scheduled for August 23-24. Having launched on July 14, Chandrayaan-3 elegantly slipped into lunar orbit on August 5.

Simultaneously, in a different corner of the world, Russia’s Luna-25 mission has captured attention with its planned landing between August 21-23.

For some years now, scientists from various space agencies, including NASA, have been uncovering the presence of frozen water in the craters of the moon’s South Pole. This discovery holds immense significance as this ice could potentially serve as a critical resource for fuel, oxygen, and even drinking water, providing essential support for future lunar colonization efforts.

Both the Russian Space Agency, ROSCOMS, and the Indian Space Research Organisation (ISRO) are on the verge of creating history as they embark on their respective journeys toward the lunar South Pole.

Contrary to being a mere race to the moon, these two missions are a synchronized exploration of uncharted territories. Chandrayaan-3 marks India’s third attempt at reaching the moon and its second endeavor to touch down on the lunar South Pole. In contrast, the Luna-25 mission signifies Russia’s first lunar expedition since 1976.

In addressing potential concerns about mission overlap, ROSCOMS has reassured that the two missions have distinct landing sites, eliminating any possibility of interference or collision. There’s an abundance of space on the moon, allowing both endeavors to coexist harmoniously.

Former ISRO Chief, Dr. K Sivan, emphasized the shared spirit of exploration. He highlighted that while the order of arrival might not significantly impact the mission outcomes, it underscores the collective commitment to pushing the boundaries of human exploration.

India’s satellite aims to achieve a lunar landing within 40 days of its launch, whereas Luna-25 is on course to accomplish this feat in a much shorter 11 days. This speedy trajectory of Russia’s lunar satellite can be attributed to its lightweight design and efficient fuel management, allowing for a more direct path.

With a leaner takeoff mass of 1,750 kilograms, Luna-25 holds a distinct advantage over Chandrayaan-3, which weighs 3,900 kg.

According to Chrisphin Karthick, a scientist at the Indian Institute of Astrophysics in Bangalore, this healthy competition fosters innovation and enhances spacefaring capabilities collectively. It demonstrates progress while adhering to both timeline and economic considerations. While cost-effectiveness is taken into account, it doesn’t deter the pursuit of excellence.

Ultimately, regardless of the outcomes, whether in Russia or India, the nation that achieves a successful soft landing will etch its name in history. These lunar missions symbolize not only space prowess but also a dedication to exploration.

Chandrayaan-3: The Journey So Far

Launched on July 14 via the powerful Launch Vehicle Mark 3 (LVM 3) rocket, Chandrayaan-3 embarked on its voyage from the Satish Dhawan Space Centre in Sriharikota. This mission boasts a lander, a rover, and a propulsion module. After covering 384,000 km, the LVM 3 is now poised for its lunar touchdown scheduled between August 23-24. It successfully entered lunar orbit on August 5.

Thus far, ISRO has executed five maneuvers to gradually adjust Chandrayaan-3’s orbit, positioning it over the lunar poles. The Vikram lander detached on August 18, following the fifth maneuver, setting the stage for the all-important landing attempt. A second deboosting operation is scheduled for August 20, 2023.

Following the landing, the rover will engage in experiments on the lunar surface for a period equivalent to one lunar day, which translates to 14 days on Earth.

Luna-25: Key Aspects and Progress

After overcoming multiple delays and obstacles, Russia’s Luna-25 was finally launched on August 11. A Soyuz rocket carried the four-legged lander, weighing around 800 kilograms, to the Vostochny cosmodrome. The eagerly anticipated touchdown is scheduled for August 21-22, targeting the lunar South Pole.

The Russian mission will orbit at an altitude of 100 kilometers (62 miles) before its planned landing north of the Boguslawsky crater on the lunar South Pole. It entered lunar orbit on August 16.

Russia’s Luna-25 spacecraft recently underwent an orbit adjustment on August 18, further solidifying its upcoming landing attempt near the moon’s South Pole, as reported by Reuters.

While Chandrayaan-3’s plans involve navigating the lunar South Pole over a span of two weeks, Luna-25 aims for a more ambitious engagement lasting a year. As of Thursday, Chandrayaan-3 has successfully completed 34 days since its July 14 launch, while Luna-25 has marked a week since its launch.

Much rides on the success of these lunar missions. For India, a successful Chandrayaan-3 mission would represent a significant recovery from a previous attempt’s setback. Meanwhile, for Russia, this lunar mission after a 47-year hiatus reaffirms its standing in the realm of space exploration.

As the countdown to their respective landings gains momentum, both nations stand at the precipice of a historic achievement. The eyes of the world are fixed on India and Russia, eagerly awaiting the news of who will be the first to leave their mark on the moon’s South Pole—an accomplishment that resonates with dreams and aspirations that extend beyond Earth’s boundaries.
