Had Chandrayaan been really less than forthcoming??


I find the Chinese attitude both interesting and dismaying.  It is similar to one that I experienced with Indian Space Research Organization during the Chandrayaan-1 lunar orbiter mission.  When the Chandrayaan spacecraft was running into difficulties after a few months in lunar orbit, the organizational instinct was to deny any problems and be less than forthcoming with the press about the status of the spacecraft.  Spaceflight is inherently difficult and things break all the time.  It is beyond ridiculous to cover up a problem by pretending that it doesn’t exist.  Similar behavior patterns characterized the early Soviet space program, in which we never heard about mission failures, but successes were given widespread publicity.  It seems that to date, China is adhering to that model

Is this true?? Did we(ISRO) really acted like there were no failures...Though its true, is it really that dismaying?? Isn't it the nature of human to boast abt successes and deny failures?? Little bit disappointing with this article of Spudis...Though I still love his writings ;)

Ofcourse, this could be strange to people those who confirmed pockets of water with bistatic rada experiment and later denied it with radar observations of arecebo. Anyways your truthful ness is to be praised here.

Why Volcano...In simple language

This is the explanation I have come across in Lunarnetworks blog...This is soo simple and understandable in a go..I just loved it...See why volcanism and How volcanism in a few lines


It is necessary to understand some elementary facts about planetary geology.  Planets generate heat and this heat must be dissipated.  Typically, the heat generated from both the original energy release during formation (accretion) and from the decay of radioactive elements (e.g., uranium) melts the interiors of planets, forming bodies of liquid rock called magma.  This magma is usually less dense than the rocks from which it forms and thus, rises upwards towards the surface.  Sometimes, the molten rock cannot ascend any higher from the deep locations where it comes from and freezes in place – geologists call this type of frozen rock body an intrusion, because it intrudes into pre-existing rock as a liquid and then solidifies by crystallizing.  When magma actually reaches the surface of a planet, it can erupt onto its surface as lava; this activity is called extrusive because the molten rock extrudes onto the surface and then solidifies as lava flows.
