Mangalyaan, also known as the Mars Orbiter Mission (MOM), is a space probe launched by the Indian Space Research Organisation (ISRO) in November 2013. The mission's goal was to orbit Mars and study its atmosphere, geology, and potential for hosting life.
The mission was considered a major achievement for ISRO, as it was not only the first interplanetary mission for the agency, but it was also completed on a shoestring budget of around $74 million, making it one of the most cost-effective interplanetary missions to date.
Mangalyaan was launched on November 5, 2013, using ISRO's Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre in Sriharikota, India. After a successful launch, the spacecraft spent more than a year traveling to Mars, covering a distance of over 690 million kilometers.
On September 24, 2014, Mangalyaan successfully entered into orbit around Mars and began transmitting data back to Earth. The spacecraft was equipped with five scientific instruments to study the Martian atmosphere, surface features, and mineralogy.
Some of the mission's notable achievements include the discovery of methane in the Martian atmosphere and the detection of evidence for water on the planet's surface. The mission also provided valuable information on the planet's geology and atmosphere, and helped to improve our understanding of the history and potential for life on Mars.
The mission was declared a success on September 24, 2014 and it lasted more than 6 years, providing valuable data and making India the first country to successfully reach Mars on its first attempt.
Mangalyaan is an example of the great potential of countries with lower resources and budget to achieve big goals in space, opening the doors for other countries with similar situations to do the same.
There were several notable achievements made by the Mangalyaan mission:

Longevity: The mission was declared a success on September 24, 2014 and it lasted more than 6 years, providing valuable data and making India the first country to successfully reach Mars on its first attempt.
The Mangalyaan mission made several important discoveries during its time orbiting Mars, including:
Methane Detection: As mentioned before, the Mangalyaan mission detected the presence of methane in the Martian atmosphere, providing evidence of potential active geological or biological processes on the planet.
Evidence for water: The spacecraft's instruments also detected evidence for the presence of water on the planet's surface in the form of hydrated minerals. This discovery adds to the growing body of evidence that Mars may have had a watery past, and potentially could support life.
Increased understanding of Martian Geology: The mission provided valuable information on the planet's geology, including the composition and structure of its surface and subsurface layers. This helped scientists to understand the processes that have shaped the Martian surface over time, and provided insights into the planet's geologic history.
Improved understanding of Martian atmosphere: The spacecraft's instruments allowed scientists to study the Martian atmosphere in greater detail, providing insights into the planet's weather patterns and the processes that shape its climate.
Detection of Deuterium-Hydrogen ratio: The mission helped in the measurements of the deuterium-to-hydrogen ratio in the Martian atmosphere.
Images and mapping: The spacecraft's cameras and spectrometers captured high-resolution images and spectra of the Martian surface, providing detailed information about the planet's geology and mineralogy.
All these discoveries allowed scientists to learn more about the planet's potential for past or present life, as well as its geology and atmosphere and potential for future human exploration.
It's important to remember that discoveries like these often come from multiple space missions and the data of Mangalyaan added valuable information to the existing knowledge about Mars, helping to build a more complete picture of the planet.
The detection of methane on Mars by the Mangalyaan mission was a notable achievement, as it provided evidence of potential active geological or biological processes on the planet.
Methane is an important gas on Earth because it is a byproduct of many biological and geological processes, such as the decomposition of organic matter and the alteration of certain types of rock. On Mars, the detection of methane is particularly interesting because the planet's surface is very dry and cold, and its atmosphere is also extremely thin, so the preservation of methane is difficult. Therefore, the detection of methane on Mars is significant because it suggests that there may be a source of the gas that is currently producing it, or that there may have been a source of the gas that was active in the recent past.
Methane detection on Mars was not an easy task, but the instrument aboard the Mangalyaan spacecraft, the Methane Sensor for Mars (MSM) was able to detect the trace amounts of methane in the atmosphere. The data collected by the MSM was used to produce maps of the distribution of methane on Mars, providing scientists with information about the potential sources of the gas.
Based on the data, scientists have proposed several possible explanations for the presence of methane on Mars, including the possibility of active volcanic activity, the presence of subsurface reservoirs of methane-containing fluids, or the presence of microbial life on the planet.
It's worth noting that the methane detections are still not conclusive, more data is needed to confirm the presence of methane and understand its source. Also, other space agencies like NASA and ESA have attempted to detect methane on Mars with limited success, So, the discovery of methane is still considered as a mystery and requires more research and confirmation.
Longevity
The Mangalyaan mission was designed to last for six months, but it far exceeded its original design lifetime, lasting more than six years. The mission was declared a success on September 24, 2014, but the spacecraft continued to function and transmit data back to Earth long after that date. The longevity of the mission provided scientists with a wealth of data on the Martian atmosphere, geology, and potential for life, allowing them to conduct more comprehensive studies of the planet than would have been possible otherwise.
One of the reasons for the mission's longevity was the spacecraft's design. The Mangalyaan spacecraft was engineered to withstand the harsh conditions of space, including extreme temperatures, radiation, and micrometeoroid impacts. This allowed it to remain functional for much longer than initially planned.
Additionally, The mission's management also played a key role in the mission's longevity, as the spacecraft's systems and instruments were carefully monitored and maintained by engineers and scientists at ISRO throughout the mission.
The extended lifetime of the Mangalyaan mission was a remarkable achievement, and it provided a wealth of scientific data that will be studied for years to come. The mission's longevity also allowed ISRO to demonstrate the durability and robustness of the spacecraft it developed, as well as its ability to conduct high-quality scientific research over long periods of time.
In summary, the Mangalyaan mission is a great example of how a well-designed, well-managed spacecraft can far exceed its planned lifetime and achieve a great deal of scientific success.
