India test-fires Mars mission engine - The Times of India

The engines of the Indian Mars orbiter were tested for the first time on Monday morning. Speaking to TOI from Bangalore, Isro chief spokesperson Devi Prasad Karnik said the engine, known as the liquid apogee motor (LAM), was fired for about 670 seconds at Isro's Liquid Propulsion Systems Centre at Mahendra Giri in Tamil Nadu. "The test was successful and will go on for about 45 days," he said.

The mission is slated for lift off towards the end of October or beginning of November 2013.

LAM plays a key role in orbit raising manoeuvres. The current mission profile of the mission envisages the orbiter operating in the earth-bound orbit six times as its altitude is raised, before it sets off on its 300-day journey to Mars.

In the final earth orbit, the orbiter's furthest point from earth will be 2,15,000 km and the nearest 600 km. It is expected to depart from the earth's orbit on November 26, 2013, and the crucial Mars orbit insertion will occur on September 21, 2014.

An Isro official said the real challenge in the mission is that the engine has to restart after 300 days when the orbiter enters the Martian orbit.

What an utter waste of money. Build toilets and roads here instead of sending missions to Mars.

Enjoy Congress Bi*tches, Enjoy Secularism, Enjoy the Nehru Rate of Growth, Enjoy Socialism, Enjoy World's Largest Number of Poverty!

It is Mars Mission which will give India Power and Respect not the $10 Billion NREGAs, $20 Billion Food Security Bill and Scams.

You guys should know that Indian space program has saved billions worth destruction, thousands of lives and millions in profit.

Every new technology being used in these type of missions, helps in increasing industrial level. helps us becoming self-reliant and hence save money which is used in nation's development.

Kindly look at things with different perspective.

I am not defending Congress, just defending ISRO.

The only major benefit i can see of Mars mission is it allows greater collaboration with other International Space Organization and some of the results are in research for example L/S UHF Antenna

Roads will be

But not sure about Toilets

International Development Select Committee Inquiry into British Aid to India

however, a survey of 7 districts found over twice as manyhouseholds with televisions as with toilets and the same proportion with mobile phones, indicating that for many households sanitation has been a lowpriority rather than unaffordable.

Toilet seems to be more of an awareness problem.

No need to explain them in larger context buddy , they have lost it !!

Any body who is opposing Mars mission is ignorant and do not know anything about it.

Fact is India is spending 82 million us dollars on it which is very low amount compared to other Govt. projects. The benefits out weigh the amount we are spending on it.
This is a technology testing mission which will become a base for future launching mission.

That is such a retarded comment. Just because India spends money on space or space programs doesnt mean its a waste of money. Here are a few reasons why its not a waste of money, but rather an investment, that should be increased as time goes on:

Remote Sensing: Today, India operates one of the largest and most advanced remote sensing satellite constellations of any country on Earth. We’ve got satellites pointing at Earth, operating in a system that’s accurate down to about one meter. The system is used to monitor and detect resources: it helps find well water in dry regions of India, so far saving the government’s drill boring program $100 million. They also use it to project crop yields, the health of fisheries, pest infestations, agricultural diseases, flood forecasting, urban planning, and road construction. Satellites are also used for gathering meteorological data—for understanding daily weather and longer-range climatic patterns, creating an alarm system for disaster preparation (did you know 95% of all deaths from worldwide natural disasters happen in the least developed countries in the world?!?), and providing a system for coordinated search and rescue efforts on land, sea and air.

Tele-education: In 1974, NASA moved its ATS-6 satellite over to India for about a year to undertake a special experiment (considered the “largest sociological experiment in history”): see what satellites can do if used in the service of broadcasting educational television to poor communities in India. Jointly developed by the U.S. and India, the Satellite Instructional Television Experiment (SITE) ran for about a year, broadcasting 1,200 hours of programs to 2,400 villages, reaching about five million people. Subjects included science education for kids, agriculture, health, hygiene, family planning, rural development, and literacy. Ground sets to receive the signals were constructed out of chicken wire and signal converters. TV sets were distributed, mainly to schools. 600-800 people crowded around a single television set.

Today, because of investments made to develop autonomy in its aerospace sector, India can launch its own satellites. The country’s EDUSAT program connects about 55000 schools and colleges, reaching 15 million students every year.

Tele-medicine: India’s cities have world-class hospitals and doctors, but what about the roughly 850 million people living in rural villages? This is where the concept of tele-medicine comes in. Tele-medicine brings specialist doctors from cities into villages via satellite communications and mobile telemedicine units, or “clinics-on-wheels.” These have satellite dishes to connect doctors to patients who can’t afford to travel or aren’t healthy enough to make the journey themselves to the city hospitals. Today, Indian satellites have enabled a network of 382 hospitals with telemedicine capability. Of those 382, 306 are classified as remote/rural/district hospital/health centers, 16 are mobile telemedicine units and these are connected to 60 specialty hospitals. According to the Indian Space Research Organization (ISRO), the mobile units provide medical diagnoses and “are extensively used for tele-ophthalmology, diabetic screening, mammography, childcare and community health.”

Oh yeah, one more thing. All the software, hardware, communications equipment and satellite bandwidth is funded through the Department of Space and 150,000 people are benefitting from this system every year.

These are just a few examples of why India is investing in space.

If you’re like most people, space program = an expensive, potentially (but not always) scientifically rewarding pursuit yielding who-knows-what-gee-wiz facts about the universe, engaged in by highly educated people in wealthy, western nations in an exclusive, secretive effort. And that costs a ton of money, blah blah blah.

Well, it really doesn’t cost a lot of money (NASA’s budget is about half of one percent of the U.S. government’s total spending and it PAYS FOR ITSELF AND THEN SOME, yielding far more return than most government investments because it directly fuels technological innovation, growth of high-tech industries, and economic growth both locally and nationally).

And yes, India also invests in pure scientific and exploration missions, including an upcoming mission to land a rover on the moon, another to investigate Mars, and an initiative to launch people into space… all for less than 10% of their total budget of about $1.3 billion (which, itself, is about 7.5% of NASA’s total budget and also about half of one percent of India’s entire government budget).

My points here are that: 1) this is small change and 2) investing in space is a GOOD THING!!! Even, and perhaps especially, in the developing world. It's a good thing economically, scientifically, inspirationally and developmentally.

So saying, build toilets etc instead of space programs, is fuckin retarted.

Great to see Mars mission moving on time and schedule. This should be implemented in all ISRO projects. I wished for a rover too, but a satellite is okay for now.
 
. . . .
For no reason space is called the final frontier, control space control everything, leave the advancements in remote sensing, leave education, think about the various researches we can perform outside the atmosphere beneficial for mankind though a danger when performed inside earth, think about the further researches on variola virus, material sciences, space weather and many more.

If chandrayan was the first step by India towards space, through the mars program we are moving it one step forward, this kind of program's are necessity of any nation which aspire to be self reliant.
