Reaching Mars in Lowest Costs

The Mars Orbiter Mission (MOM) of the Indian Space Research Organization has got its due share of praise from the world since 24th September, when the Mangalyaan satellite entered the Martian orbit. Not only is MOM the only successful maiden attempt by a country to get a satellite into Mars’ atmosphere, but also the cheapest so far.

The only other successful Mars orbiter missions have been by the USA and the European Union, called MAVEN and Mars Express, respectively. Made possible with costs as high as $671 billion and $386 billion, they are approximately ten times and five times MOM’s total cost.

Here’s analyzing the reasons for its incredibly low cost among a total of fifty-one attempts made the world-over, and the prospects that this landmark achievement brings for the sub-continent’s economic future.

Indigenous Technology: As the economic superpowers of the world spent billions on research for their mission to reach Mars, their findings and developments were kept confidential for them to single handedly tap the economic inflow later. Not having access to the developments made by other nations on this front, ISRO had to work on the program from scratch, which played in its favor. The satellite reached Mars following a trajectory unlike any other attempted earlier. While the others aimed at sending a rocket straight towards the red planet, MOM took an elliptical orbit, first orbiting around the Earth for several days, and then gradually shifting its orbit to an elliptical one around the Sun. The solar satellite then kept increasing its radius and reached Mars after around eleven months of drifting.

This saved a huge amount of money that would have been spent on fuel to propel the payload at an incredible speed if the trajectory was to be straighter, and further reiterated the adage: necessity is the mother of invention.

Low Employee Costs: The NASA’s annual budget is upwards of $17.5 billion, whereas ISRO’s budget is approximately $1.2 billion annually. As these organizations spend heavily on research, employee costs form a huge chunk of such expenses. A middle level official at ISRO earns approximately Rs. 1 Lakh a month, which is negligible compared to how the USA compensates its scientists.

Lower Payload: Mangalyaan’s launch weight was 1350 kg and the final payload is not over 15 kgs, which again is paltry in comparison to its counterparts. MOM has been equipped with minimal scientific equipments, primarily focusing on checking for the presence of methane on the planet, as that would give some insight into possibility of life on Mars. The low weight also prevented ISRO from adding additional protective gear to the orbiter, which makes MOM incapable of landing on the surface of Mars.

Low Budget for Space Research in a Developing Economy & Business Prospects: As a fifth of India’s population still remains below poverty line, the economy’s focus is on providing more basic necessities like healthcare, education and nutrition.

However, India remains aware of the business it might get from other countries for putting their telecommunication and other satellites into space at the most competitive cost, and the decision to keep a budget for space research and technology, however small, has proved to be a wise step for the country.
