Communication Lost With Indian Moon Satellite 186

      I am quoting from a local language news paper ( http://www.keralakaumudi.com/ [keralakaumudi.com] ) from India:

      Preliminary analysis shows that Chandrayan likely failed due to inadequate heat shielding (problem was radiated heat from the Moon) causing some of the instruments to fail (like Star Sensor). They raised the orbit to around 200km (from the initial 100km) to save the mission and it did not help much.

      According to the report Chandrayan was successful in completing 95 percent of the mission objectives. The reports also said that they (ISRO) are going ahead with the next moon mission.

      • Uuum... if it did not survive the "heat" of the Moon, how did it survive the real heat of earth (athmosphere) and launch then...?

      The whole mission cost only $75 million, about 7 times the Ansari X-Prize (still considerably bigger than Google Lunar X-Prize though). That's pretty cheap for a full moonshot and satellite. So I guess India can afford to lose a few satellites here and there.
      Last month they had a malfunction and pulled the satellite up from a 100km orbit to a 200 km one , so the images are of lower quality than planned. I am guessing there will be another moonshot now, considering they just started calling this the "Chandrayan-1" instead of "Chandrayan" with no numbers next to it.

        I wish that ppl would stop trying to assign DOLLAR figures to China, Indian, or any other country that ties their money to a certain money. Saying that it cost 75 million is plain wrong (most estimates in India show it to be in the $90-95 million). Right now, the Rupee is FORCED by India to trade at 48 rupee to a dollar. According to most economist, it should be around half of that, or possibly less (more difficult to pin this down, than say the Chinese games with Yuans). As such, the missions is around $150-200 million. But, that is STILL not the full truth. The majority of expensive instruments on the sat are from different countries. Basically, the LAUNCH is what costs about $100-150 million, with the sat being less than $50 million. And at a 100 million per launch, they are on par with America, Russia, and EU.

        I am not trying to belittle their efforts. In fact, far from it. I applaud them and hope that we will bring them into the ISS down the road. BUT, I still prefer that ppl are honest about what is going on.

      Also, I found it a little strange that the BBC article didn't mention this, but the Chandrayaan-1 had already been in successful operation for 312 days and had completed all of its primary mission goals. It had already collected plenty of scientific data, distributed to not just Indian scientists but also collaborators in Europe and the US. Of course, another year would be nice, but I'd consider the project a stunning success by just about any reasonable definition, especially since it was India's first ever lunar probe.

      I look forward to India's Chandrayaan-2, which is planned to land a robotic rover on the Moon in 2012.

    • Well said sir. Not many countries have operated a satellite around the moon and achieved their primary objectives in nearly a year of successful operation. The more countries (and private concerns) that do so the better, we need more countries with space ambitions.

    Orbiting the moon is a lot harder than orbiting the earth. The moon's gravitational field is exceptionally lumpy [wikipedia.org] because of concentrations of mass beneath the surface. If not actively corrected for, these mass concentrations will make a satellite's orbit go through increasingly violent gyrations until it eventually intersects with the surface.

    I wonder if this is what happened to the Indian probe.

    • If not actively corrected for, these mass concentrations will make a satellite's orbit go through increasingly violent gyrations until it eventually intersects with the surface.

      While that sounds pretty good, I'm fairly certain from a logical standpoint the odds of impacting the moon are as good or worse than the odds of leaving orbit and flying out into space. (Especially with the low gravity levels of the moon.)

        I'm less than certain. Intersecting with the Moon would only require changes in ellipticity, whereas causing the satellite to become unbound would require a considerable increase in the satellite's kinetic energy.

        No.

        The lumps of heavier density inside the moon caused localized areas of increased gravity which tries to pull the satellite down. There is no force, except that provided by any motors on board the satellite, that would sent it out towards space.

        What school of logic do you claim as an Alma Mata?

        • What you said actually makes sense upon further thought. I wouldn't call myself certain in either line of thought currently.

          My original thought was that after going through an area of increased gravitational pull, then hitting an area of lower gravitational pull, the satellite's trajectory would be altered in such a way over time that it could break free from the gravitational effect of the moon if it hits a lower gravitational field at a necessary point within its altered orbital path.

          Now what I'm curious

    • No. They had an earlier malfunction which was corrected by pulling the satellite up from a lower orbit. They were flying fine at 100 Km altitude earlier, and they moved it up to 200 km [isro.org] to be safe. They were actively studying gravitational perturbations of the surface, so it is unlikely that they did not plan for such an eventuality.
