 Chandrayaan-3: India Moon lander's reawakening unlikely as lunar night looms

Introduction

In the world of space exploration, India has made significant strides over the years, particularly with its Chandrayaan missions. Chandrayaan-1, India's maiden lunar mission, made headlines globally when it discovered water molecules on the moon's surface in 2008. Subsequently, Chandrayaan-2, launched in 2019, aimed to take a giant leap by landing a rover on the moon. Although the rover never touched the lunar surface as intended, India's space agency, ISRO (Indian Space Research Organisation), demonstrated remarkable precision in orbiting and studying the moon.

Now, with Chandrayaan-3, India is gearing up for another lunar landing attempt. However, the mission faces challenges that make its reawakening unlikely as the lunar night approaches.

The Chandrayaan-3 Mission

Chandrayaan-3, a collaborative effort between ISRO and Russia's space agency, Roscosmos, was envisioned as a follow-up to the Chandrayaan-2 mission. The primary objective of Chandrayaan-3 was to achieve a soft landing on the lunar surface, a feat that was narrowly missed during the Chandrayaan-2 mission when the Vikram lander crashed in September 2019.

The Chandrayaan-3 mission planned to rectify past mistakes and accomplish a successful landing, carrying a suite of scientific instruments to study the moon's geology, topography, and exosphere. However, the odds have stacked against Chandrayaan-3 as it faces challenges with time running out.

The Challenge: The Lunar Night

One of the most significant challenges facing the Chandrayaan-3 mission is the lunar night. The moon experiences extreme temperature variations between its day and night, with daytime temperatures soaring to over 250 degrees Fahrenheit (120 degrees Celsius) and plummeting to nearly -250 degrees Fahrenheit (-157 degrees Celsius) during the lunar night. These drastic temperature shifts pose a severe threat to the mission's success.

The lunar night can last for approximately 14 Earth days, during which the moon is plunged into frigid darkness. Without sufficient power and thermal protection, the lander and its instruments would not survive the night. Unlike the original Chandrayaan-2 mission, Chandrayaan-3 does not include a rover, which might have provided some insulation and mobility during the lunar night.

The Power Problem

One of the main challenges during the lunar night is maintaining power generation and storage. Solar panels are typically used to harness solar energy, but during the night, they cease to function, leaving the lander dependent on stored power. The lander must rely on its onboard batteries to survive the cold, dark night, and these batteries must be capable of withstanding the extreme cold without losing their functionality.

However, designing batteries that can endure such harsh conditions is a complex engineering task. The lander's batteries need to maintain their capacity and function throughout the lunar night to ensure that the lander can "reawaken" once the sun rises again.

Conclusion

While India's Chandrayaan missions have displayed impressive technical prowess, Chandrayaan-3 faces a formidable challenge as it prepares to confront the lunar night. The absence of a rover and the need for robust power generation and storage systems make its reawakening unlikely as the lunar night looms.

Despite these challenges, India's space agency, ISRO, has a track record of innovation and determination, and it's possible that they may devise creative solutions to overcome these obstacles in future missions. The success of Chandrayaan-3 would not only be a significant achievement for India but also a testament to human ingenuity in the exploration of our celestial neighbor, the moon.
