NEW DELHI – India is set to launch a space mission to Mars on Tuesday that, if successful, would beat China to the punch, although some wonder whether the undertaking is the best use of money when many Indians lack food, clean water or basic sanitation facilities.
The 3,000-pound Mars Orbiter Mission probe, or Mangalyaan, is set to lift off at 2:38 p.m. local time (4:18 a.m. EST) aboard a 350-ton, four-stage Polar Satellite Launch Vehicle, the first step in its 300-day trip to the red planet. The cost of the mission is approximately $73 million.
The launch – which follows India’s successful 2008 moon orbiter mission, the Chandrayaan-1 – is scheduled to take place at the Satish Dhawan Space Center in Sriharikota on the Bay of Bengal some 60 miles north of Chennai in southeastern India.
If successful, India would be the sixth nation to launch a Mars mission, after the U.S., Russia, China, Japan and the European Union. But only three of those reached the planet’s orbit – China and Japan failed – underscoring the long odds.
If all goes as planned, the orbiter will take about 47 minutes to reach Earth orbit, where it will stay until Dec. 1 before starting the 240-million-mile voyage to Mars. The vessel is slated to reach the red planet’s orbit around Sept. 24, 2014.
For added insurance, the chairman of the Indian Space Research Organization sought the blessings of Lord Vishnu, the Hindu god of preservation, placing a scale model of the launch vehicle, the PSLV-C25, at the idol’s feet Monday at the lavish Tirumala shrine 80 miles from Chennai.
“These temple visits helped destress the mind and offer clarity,” the Hindustan Times newspaper explained.
Civic groups have criticized the cost, in a country where hundreds of millions of people still lack toilets. “I think it’s so strongly symbolic of an extremely unequal society,” said Harsh Mander, director of New Delhi’s Center for Equity Studies, a think tank, and a former adviser to the prime minister on social issues. “We continue to have something like 230 million people who sleep hungry every night, and millions die because they can’t afford health care. Yet these are not issues that cause outrage.”
But scientists defended the mission, arguing that it costs only a little more than 6 cents per capita in a nation with a population of 1.2 billion, roughly the same as an aircraft, and brings pride to the country.
“There are social benefits,” including weather satellites that save lives, said Ajey Lele, a research fellow with the Institute for Defense Studies and Analyses, a think tank. Of the opposition to the mission, Lele said, “I think all these arguments are mere rhetoric.”
Indian scientists said the mission has two objectives. It will test and showcase Indian technology as India attempts its first foray beyond Earth’s orbit through some of space’s harshest conditions. And once in Mars’ orbit, it will attempt scientific experiments related to climate, geology and evidence of past water, pointing to possible signs of early life.
India also hopes a successful mission will promote the capability and affordability of its commercial satellite-launching service. So far, it has launched 35 satellites for other countries, Lele said, and is eager to do more. This mission’s $73 million price tag compares with $2.5 billion for NASA’s Mars Curiosity mission and $1.5 billion for a NASA rover planned for 2020.
“India’s making a statement,” Lele said, “that we can do it.”
