RAJYA SABHA
During April 2009, 2nd star sensor used for orientation of Chandrayaan spacecraft towards Moon had failed. Alternate method using Gyroscope and Antenna had been implemented for orienting Chandrayaan towards Moon.
Due to the loss of communication link with the Chandrayaan-I, it was not possible to take any further corrective steps.
The total cost of Chandrayaan-I mission from Concept to Commissioning to ultimate calling-off is Rs. 386.00 crores, including the cost of establishment of ground infrastructure.
This was stated by Shri Prithviraj Chavan, the Minister of State (I/C) for Science & Technology and Earth Sciences in the Rajya Sabha today
You know how this can relate to this thread is a Bit vague.
The Sensors on CH-1 failed. But it was not due to Equipment being sub-standard. But Due to heat exposure.
ISRO has underestimated how much heat would reflect of the Moon.
Thus when CH-1 entered orbit it's fine instruments began to overheat and well fail. when the primary senor failed they raised the orbit by a 100 km. But the damage had already been done
But respect where respect is due, I dont see Man made objects entering moon orbit everyday. and then sending back date proving the presence of water on the surface..
