ISRO's Mars Orbiter Mission 2: Details Emerge

New Delhi, March 28, 2026 – India's space agency, ISRO, is gearing up for its next ambitious interplanetary venture: the Mars Orbiter Mission 2 (MOM-2). Building on the success of the first MOM, which placed India among the elite nations to reach Martian orbit, MOM-2 promises a more in-depth study of the Red Planet's atmosphere, surface, and potential for past or present life. This week, ISRO officials have released more details about the mission's objectives and planned launch window.

MOM-2, unlike its predecessor, will likely include more advanced scientific instruments and a higher resolution imager. While the payloads are still being finalized, sources within ISRO reportersays that the mission will prioritize atmospheric studies, searching for methane and other biosignatures. The orbiter will also carry a hyperspectral imager to map the Martian surface composition with unprecedented detail. This data will be crucial in understanding the planet's geological history and identifying potential landing sites for future missions.

MOM-2: Key Objectives and Scientific Payloads

The primary objectives of MOM-2 are to further investigate the Martian atmosphere, search for evidence of past or present microbial life, and analyze the planet's surface composition. To achieve these goals, the orbiter is expected to carry a suite of advanced scientific instruments, including:

• Atmospheric Methane Sensor (AMS): Will precisely measure methane concentrations in the Martian atmosphere, helping scientists understand its origin and distribution.
• Hyperspectral Imager for Mars (HIM): Will capture high-resolution images of the Martian surface across a wide range of wavelengths, allowing for detailed mineralogical mapping.
• Mars Environment Dynamics Analyzer (MEDA): Will monitor the Martian weather, including temperature, pressure, humidity, and wind speed.
• Radio Science Experiment (REX): Will use radio signals to probe the Martian ionosphere and atmosphere, providing insights into their structure and dynamics.

Comparing MOM-2 with Other Mars Missions

While several nations have successfully sent missions to Mars, MOM-2 stands out due to its cost-effectiveness and focus on specific scientific objectives. Comparing it to NASA's Perseverance rover or the European Space Agency's ExoMars Trace Gas Orbiter, MOM-2 offers a unique perspective from orbit, complementing the data gathered by surface-based missions. NASA's MAVEN mission, for instance, focuses on the upper atmosphere of Mars, while MOM-2 will provide a more comprehensive view, encompassing both the upper and lower atmospheric layers. This holistic approach is expected to yield valuable insights into the planet's climate and habitability.

Speaking to News Reporter Live, Dr. Anuradha T.K., a retired ISRO scientist involved in the first MOM mission, expressed her excitement about MOM-2. "MOM was a remarkable achievement, demonstrating India's capabilities in interplanetary exploration. MOM-2 has the potential to build upon that success, providing us with a deeper understanding of Mars and its potential for life," she said.

India Launch Date and Expected Cost

ISRO is targeting a launch window in late 2028 for MOM-2, depending on the alignment of Earth and Mars. The mission is expected to cost approximately INR 450 crore, making it one of the most budget-friendly Mars missions ever undertaken. The launch will likely be from the Satish Dhawan Space Centre in Sriharikota, using ISRO's reliable Geosynchronous Satellite Launch Vehicle (GSLV).

The success of MOM-2 would further solidify India's position as a major player in space exploration, fostering scientific innovation and inspiring future generations of scientists and engineers. The data obtained from the mission will be invaluable for understanding the Red Planet and paving the way for future human missions to Mars.
