Chandrayaan-3: Possible Reawakening of Vikram Lander After Lunar Night

Share -

India’s prestigious space agency, ISRO (Indian Space Research Organisation), is anxiously anticipating a pivotal moment in its lunar exploration endeavors as the Vikram lander, a component of the Chandrayaan-2 mission, is poised to awaken from its hibernation following an extended lunar night. This event, scheduled for September 22, has ignited considerable enthusiasm and interest within the global space exploration community.

The Chandrayaan-2 mission, launched in July 2019, was aimed at delivering the Vikram lander to the lunar south pole. Unfortunately, the mission encountered a setback when the lander lost communication with ISRO during its descent and ultimately crash-landed on the moon’s surface. Despite this initial disappointment, the orbiter segment of the mission has continued to orbit the moon and gather valuable scientific data.

Now, two years after the initial setback, there is renewed hope that the Vikram lander might experience a revival. This optimism is rooted in the lander’s unique design, which includes solar panels capable of recharging its batteries during the lunar daytime.

The lunar night, lasting approximately 14 Earth days, posed a formidable challenge for the Vikram lander. During this extended period of darkness, temperatures on the moon’s surface plummet to an astonishing -180°C (-292°F). These frigid conditions can be detrimental to electronic components and batteries, potentially causing permanent damage.

However, the return of lunar daylight offers a glimmer of hope. As the moon’s surface is once again bathed in sunlight, the Vikram lander’s solar panels have the potential to generate power. If the lander’s systems remain functional and have not suffered irreparable damage, there exists a possibility that it may “awaken” and reestablish communication with mission control on Earth.

The successful reconnection with the Vikram lander would constitute a remarkable achievement, not only for ISRO but for the global space community. It would serve as a testament to the resilience of Indian space technology and the capacity to rebound from unforeseen obstacles.

If the Vikram lander indeed manages to regain communication, several potential scenarios could unfold:

  1. Data Retrieval: A primary objective would be to retrieve any data stored within the lander’s instruments. This data could include invaluable insights into lunar conditions, topography, and geology.
  1. System Evaluation: Engineers would need to meticulously assess the condition of the lander’s systems, encompassing its communication equipment, propulsion, and scientific instruments. This assessment would provide crucial information regarding the feasibility of resuming scientific operations.
  1. Reestablishing Contact with Orbiter: Establishing renewed communication with the Chandrayaan-2 orbiter, which continues to orbit the moon, would be a momentous achievement. The orbiter could serve as an intermediary for transmitting data and instructions between the lander and mission control on Earth.
  1. Scientific Objectives: Should the lander prove operational, ISRO might potentially reassess its scientific objectives. This could entail conducting experiments, gathering data, and analyzing lunar samples, contingent on the continued functionality of the lander’s instruments.

While the prospect of the Vikram lander’s reawakening is generating palpable excitement, it is essential to acknowledge that the outcome remains uncertain. The lunar environment’s harsh conditions, coupled with the lander’s crash landing, pose significant challenges. Nevertheless, ISRO’s engineers and scientists have exhibited unwavering determination and ingenuity throughout the Chandrayaan-2 mission.

On September 22, the world will be closely watching ISRO’s endeavors to reestablish contact with the Vikram lander. Irrespective of the outcome, this endeavor embodies the spirit of exploration and the unrelenting pursuit of knowledge that propels space agencies and scientists worldwide. The Chandrayaan-2 mission, with its highs and lows, continues to inspire and push the boundaries of humanity’s comprehension of our celestial neighbor, the moon.
