    Is it just me or is Mangalyaan S/C of Indian Space Agency has done nothing that anyone has ever done before in space? How can a space agency that never send a S/C to another planet ever...with a rediculously low budget...complete the entire development, testing phases, launch, ground communications and deliver the spacecraft in just 2 years to a Martian orbit??? Standing at 74 million dollars, this mission is a proof that commercial space companies can do this sort of thing. Is insane...Did they underpay their software engineers? Is that why this is happening?

    No engineer was underpaid. And why are you looking for nevelties. It carries 5 payloads, two provided by NASA.

    Low cost is because that is the done thing. After all India has launched many foreign satellites too. All because the Indian launchers are highly reliable and cost effective.

    This is the first thread on Mangalyaan, and too highly negative.

    Pay there is very , very low.

    Varied from 118 rupees ($2.18) per day in Bihar to 185 rupees ($3.40) per day in Haryana (with local cost of living allowance included). State governments set a separate minimum wage for agricultural workers.[102]The minimum wages are set according to Minimum Wages Act.

    Earth2Orbit Susmita Mohanty is a CEO at a budding private space company in India. The focus she says of ISRO is to develop and launch space capsules, clearly a strategy out of NASA set guidelines. India seems to be relying heavily on software simulations and making multiple prototypes and conducting numerous field tests.
    How much exactly is an engineer in ISRO is paid?

    The mission was launched by Augmented Polar Satellite Launch Vehicle, into its 25th successful flight, including the lunar mission. Payloads were easily made.

    Yeah but making a successful transfer orbit maneuver on to Mars and entering capture orbit of Mars is a whole another game.

    Have you not heard that too was done on 24 Sept? Please go check.

    What do you think this thread is about?

    I am questioning how ISRO pulled out the orbit transfer and injection all in one shot under smallest cost ever.

    What software did they use to skip the testing part and utilize simulations instead.

    Look at title once again.

    Not only smallest cost with smallest or zero error too.

    Lets see the facts. NASA launched 20 after, but Maven arrived two ahead of MOM. Can you imagine the launch and cruise speeds? Heavier engines, heavier fuel loads. Higher speeds mean more robust designs of payloads too. Also heavier fuel load for retardation. Why such a tearing hurry? Did NASA want to upstage ISRO? What did ISRO lose by delay of two days, when MOM instruments were switched on before Maven? NASA HAD to test launcher as it was not 100% reliable. PSLV ia tested war horse. With 24 successful launches, what was needed more? Same with instruments, on which NASA burnt money, ISRO did not. Nine instruments of Maven at 75 kg vs five of MOM total 15 kg. When each kg costs a lot, NASA should have miniaturised like ISRO.

    Try to get the source code, you will draw a blank from both NASA and ISRO.

    Go ahead. Ponder and be at peace. Also you should ask NASA to outsource launcher. Or don't ponder and keep on burning in your hatred. Choice is yours.

    Alec the smart: If money could buy everything, USA would have colonised Mars yesterday.

    But why colonize a planet that cannot support life on its own? A colony on Mars would always need to be helped in many ways for it can't sustain itself through the years. Things break down, people kill each other, babies are born emotions are scattered and many other things. I just can't understand why, unless making a huge profit for the colony building business, this idea has to be done. Robots are becoming much more sophisticated and in the near future will have AI put into them to make their own decisions about what they need to do to finish a task. So lets save allot of money, work together with other countries and explore the universe without endangering humans.

    I fear the day AI becomes sophisticated enough to make actual intelligent decisions... because that will be the day that AI learns to better itself, create itself, and that it doesn't need us humans and our flawed ways of thinking...

    AI is already being used by many businesses today. It is still in its infancy form and during the next 10 years I think it will be in everything somehow. As an example in today's new cars they have a sensor that makes the car stop if it gets to close to another vehicle. That sensor is being worked by AI for the AI applies the right amount of brakes for the speed the car is traveling in order to stop that car without endangering the occupants lives.

    That's happening now. Self-driving vehicles can drive through city streets, often more safely than people can. They can drive off-road across the desert, design complex circuit boards, shut down nuclear power plants if they suspect a problem etc.

    Why is Maven so costly?

    much more mass for S/C but also the same old testing instead of simulations like the Mangalyaan has done.

    Is it not case of learning from ISRO?

    Again, why is MAVEN so costly?

    This is the whole reason I created this thread. I want to find ISRO planning and management plan of this particular space mission. I want to know the exact phases of the project from the concept phase to the operations phase for Mangalyaan.

    As if ISRO is going to give them to you. Will NASA give you? Start with that if want an objective comparison. But lots of tell tale facts are already known.

    1. MAVEN started 18 days after Mangalyaan and reached a day earlier. Tearing hurry, desire to beat Mangalyaan? But it did mean a more powerful booster, a heavier booster, requiring and carrying more fuel.

    2. It went at higher speed like devils were after it. Higher speeds at launch also mean more fuel for deceleration on arrival.

    3. Higher speeds also mean a heavier LAM, liquid apogee motor.. More fuel.

    4. NASA had to do simulation as each part was designed afresh, ISRO did not even require it. Can you even guess WHY? Try it, failing that ask me again.
