Building upon the success of its inaugural Mars Orbiter Mission (MOM), the Indian Space Research Organisation (ISRO) is preparing for Mangalyaan-2, aiming to land a spacecraft on Mars’ surface. This mission positions India to become the third nation to achieve a soft landing on Mars, following the United States and China.
Mission Overview: Lander, Rover, and Helicopter
Mangalyaan-2 is designed to be a multifaceted mission, comprising a lander, a rover, and a helicopter:
- Lander: The mission will utilize a lander to deliver the rover and helicopter to Mars’ surface. The lander will be equipped with advanced technologies, including a sky-crane system for precise landing, and supersonic parachutes to manage the descent through Mars’ thin atmosphere.
- Rover: The rover aims to conduct scientific experiments on Mars’ surface, analyzing soil composition and searching for signs of past or present life. It will be deployed from the lander and is expected to operate autonomously, sending data back to Earth for analysis.
- Helicopter: ISRO plans to include a helicopter, known as the Martian Boundary Layer Explorer (MarBLE), to fly in Mars’ thin atmosphere. This aerial vehicle will carry scientific instruments to study the Martian atmosphere during its flights, offering a novel perspective on the planet’s climatic conditions.
Innovative Landing Techniques: Sky-Crane and Supersonic Parachutes
To ensure a safe and precise landing, ISRO is developing a sky-crane system inspired by NASA’s successful implementation with the Perseverance rover. This system allows the rover to be lowered gently onto the Martian surface, minimizing the risk of damage. Additionally, supersonic parachutes are being designed to handle the high-speed descent through Mars’ sparse atmosphere, ensuring a controlled landing.
Communication Infrastructure: Relay Satellite
Recognizing the challenges of maintaining communication with Earth, ISRO plans to launch a relay communication satellite before the main mission. This satellite will act as a communication bridge between Mars and Earth, facilitating continuous data transmission and command execution.
Mission Timeline and Launch Vehicle
The mission is slated for launch aboard ISRO’s most powerful rocket, the Launch Vehicle Mark-III (LVM3). While the exact launch date has not been confirmed, reports suggest a target window as early as late 2024. However, given that key components like the helicopter, sky-crane, and supersonic parachutes are still under development, some experts view this timeline as ambitious.
Scientific Objectives and Global Positioning
Mangalyaan-2’s primary objective is to conduct advanced scientific studies of Mars’ surface and atmosphere. The mission’s inclusion of a rover and helicopter aligns with ISRO’s goal to enhance India’s position in planetary exploration. If successful, India would join an exclusive group of nations capable of landing spacecraft on Mars, underscoring the nation’s growing prowess in space technology.
Conclusion: A Giant Leap for ISRO
Mangalyaan-2 represents a significant milestone in ISRO’s quest for interplanetary exploration. By incorporating innovative landing techniques, advanced communication systems, and diverse scientific instruments, the mission exemplifies India’s commitment to pushing the boundaries of space research. As ISRO finalizes the mission’s components and timelines, the global community eagerly anticipates India’s next giant leap in space exploration.
