On october 22,2008 ISRO sucessfully completed its first moon mission by launching the satellite chandrayan-1.It has been launched to take the photograph of surfaces on moon.They predicted its lifetime as two years.But now one of main sensor failed to work.This is a shocking news for the scientists in ISRO.In the last eight months of its operation,it has done all the tasks which they expected.It may be totally failed at any time from now.They are yet to ascertain the reasons for the failure of the sensor.It has failed to respond to the engineers at the base station.How ever there is no need to worry as the major tasks has been completed.
