Mangalyaan 2: India's Next Leap Toward the Red Planet
Following the historic success of the first Mars Orbiter Mission (MOM), also known as Mangalyaan, the Indian Space Research Organisation (ISRO) is preparing for a more ambitious return to Mars. First announced during the Engineers Conclave in Bengaluru on October 28, 2014, the second mission—Mangalyaan 2—represents a significant evolution in India's planetary exploration capabilities.

The Evolution of the Mission Architecture
The journey toward Mangalyaan 2 has seen several shifts in strategy and scope. In January 2016, India and France signed a letter of intent for ISRO and the French space agency CNES to jointly develop the mission by 2020. However, by April 2018, French involvement was no longer evident in the mission's progress.
For several years, ISRO debated the mission's primary objective. While the Indian government provided funding in the 2017 budget proposal, officials weighed whether to deploy a sophisticated orbiter alone or a combined orbiter, lander, and rover system. In October 2019, S. Somanath, director of the Vikram Sarabhai Space Centre (VSSC), noted that the architecture remained undecided.
From Orbiter to Comprehensive Exploration
By February 2021, ISRO Chairman K. Sivan clarified that Mangalyaan 2 would be an orbiter-only mission. This phase focused on utilizing the LVM3 (Launch Vehicle Mark 3), a powerful rocket that first flew on June 5, 2017. Unlike the lighter PSLV-XL used for the first mission, the LVM3 allows for a direct-to-Mars trajectory and a significantly heavier payload.
However, the mission's scope expanded again in 2024. The updated plan now includes a comprehensive suite of exploration tools: a rover, a helicopter, a sky crane, and a supersonic parachute, marking a transition from simple observation to surface exploration.
Technical Advancements and Capabilities
Mangalyaan 2 will employ aerobraking—a maneuver where a spacecraft uses the friction of a planet's atmosphere to slow down—to lower its initial apoapsis (the highest point of its orbit). This technique allows the satellite to enter a more suitable orbit for scientific observations and reduces the perigee (the lowest point of the orbit) to approximately 200 kilometers above the Martian surface.
Due to the increased power of the LVM3 rocket and the efficiency of aerobraking, the MOM-2 satellite is capable of carrying more than seven times the payload of the original MOM-1 mission.

Frequently Asked Questions
What is the primary difference between the rockets used for the two missions?
The first mission used the PSLV-XL, while Mangalyaan 2 uses the LVM3. The LVM3 is significantly more powerful, enabling a direct-to-Mars trajectory and the ability to carry much heavier payloads.
What is aerobraking and why is it used in MOM-2?
Aerobraking is the process of using a planet's atmosphere to slow down a spacecraft. ISRO is using this to lower the satellite's apoapsis and achieve a more effective observation orbit with a perigee of roughly 200 km.
Will Mangalyaan 2 land on Mars?
Yes. While it was previously described as an orbiter-only mission in 2021, the 2024 updated plan includes a rover, a lander (via sky crane), and a helicopter.
What is the current status of the mission's approval?
The mission received approval from the Space Commission on February 21, 2025. The development of the spacecraft is expected to begin following approval from the Union Cabinet.
Was there international collaboration for this mission?
India and France signed a letter of intent in 2016 for a joint mission between ISRO and CNES, but by April 2018, France was no longer involved in the project.
