Wadliwy detektor metanu nie pozwolił na zebranie danych.
India's Mars Orbiter Mission Has a Methane ProblemBY IRENE KLOTZ PUBLISHED ON 12/07/2016
The methane-detecting instrument aboard the ISRO MOM spacecraft has been re-purposed after NASA scientists uncovered a design flaw.More than two years after its pioneering Mars Orbiter Mission (MOM) reached the red planet, the Indian Space Research Organization has yet to release highly anticipated measurements of atmospheric methane, a gas which on Earth is strongly tied to life.
Seeker has learned that the data will never come, due to a flaw in the sensor design.
"They did not design this properly for the detection of methane on Mars," Michael Mumma, senior scientist at NASA's Goddard Space Flight Center, told Seeker. (...)

(...) But the “technology demonstrator,” as ISRO calls MOM, has delivered only minimally on science expectations, critics say. For example, its methane sensor apparently has failed to detect methane plumes in the martian atmosphere. “Mangalyaan was a marvel in engineering, but no exciting science came out of [it] since the experiments and instruments themselves were mediocre,” says U. R. Rao, chairman of ISRO’s science advisory committee and a former ISRO chief. “Small instruments give small science,” he says. (...)
