Mangalyaan launches — Mars Orbiter Mission
At 2:38 in the afternoon of 5 November 2013, India's workhorse PSLV rocket climbed away from the First Launch Pad at Satish Dhawan Space Centre, Sriharikota, carrying the most audacious payload in the country's history. Mangalyaan, formally the Mars Orbiter Mission, was India's first attempt to leave Earth's gravitational neighbourhood. No Asian nation had ever reached Mars, and more than half of all missions sent there by anyone had failed. ISRO was attempting it with a rocket never designed for interplanetary flight and a budget smaller than a Hollywood film's.
The constraint shaped the mission's cleverest feature. The PSLV-XL was too small to throw the 1,337-kilogram spacecraft directly at Mars, so ISRO flew a patient slingshot instead: the rocket placed Mangalyaan in an elliptical Earth orbit of 250 by 23,500 kilometres, and over the following weeks a series of six engine burns stretched that ellipse wider and wider. On 1 December 2013, Indian time, the spacecraft fired itself out of Earth orbit entirely and began the ten-month cruise to Mars.
The numbers became legend. Approved in August 2012, the spacecraft was designed, built and launched in roughly fifteen months for about 450 crore rupees, around 74 million US dollars, less than the production budget of the film Gravity, which had premiered just a month before launch. Five home-grown instruments rode along, including a colour camera and a sensor built to sniff for methane, a gas that on Earth is overwhelmingly produced by living things. Whether the frugal gamble would pay off would not be known until orbit insertion, ten months and hundreds of millions of kilometres away.
“I have heard about the film Gravity. I am told the cost of sending an Indian rocket to space is less than the money invested in making the Hollywood movie.”

Key Facts
The PSLV could not reach Mars directly, so Mangalyaan spent nearly a month slingshotting itself, raising its orbit with six engine burns before finally breaking free of Earth on 1 December 2013.
From government approval in August 2012 to launch was roughly fifteen months, one of the fastest interplanetary developments ever achieved.
The $74 million budget undercut the production cost of the film Gravity, released just a month before launch, and was roughly a tenth of NASA's MAVEN Mars orbiter, which launched two weeks later.
The launch slipped a week, from 28 October to 5 November, because tracking ships could not reach their assigned South Pacific stations in time to monitor the ascent.
One of the five instruments aboard was a methane sensor, hunting a gas that on Earth is produced almost entirely by life.
Why It Mattered
Mangalyaan's launch announced a new model for planetary exploration: minimal budgets, recycled flight-proven hardware, and acceptance of calculated risk. The slingshot trajectory turned a modest rocket into an interplanetary launcher and has been studied ever since as a template for low-cost deep-space missions. Win or lose at Mars, the attempt itself repositioned ISRO from a builder of practical Earth-observation systems into a planetary exploration agency, and it gave a generation of Indian engineers and students proof that the solar system was within their country's reach.
