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.
