(I posted a similar comment a few months ago.[1] To be clear I have nothing against the India, its space program or its achievements, but it's impossible to discuss the low price of the mission without discussing the elephant in the room)
There is clear lack of sterilization techniques being used on the ISRO spacecraft. This is clearly visible in the public photos and videos. NASA spend a great deal of time and sterilizing deep space probes to reduce the chance of Earth microbes colonizing a place like Mars, or a moon of Jupiter, but ISRO does not.
Watch this video and showing assembly of this particular spacecraft http://www.space.com/23199-indias-first-mars-mission-prepare...
Compare the NASA cleanroom assembling Curiosity - http://www.nasa.gov/centers/jpl/images/content/482654main_pi....
Most engineers at the Indian Space Research Organisation seen directly operating on the spacecraft are not using facial masks or even gloves for interplanetary missions, let alone full cleanroom coveralls. http://www.thehindu.com/multimedia/dynamic/01608/vbk-05-mars... (via http://www.thehindu.com/sci-tech/science/indias-october-28-m...)
It would be a huge shame for us to have doubt whether the first extra terrestial microbes we find in the solar system were really alien or simply Space Age Earth based life
It also jibes with this anecdote https://news.ycombinator.com/item?id=6552078
This comment has nothing to do with India, ISRO, politics or Mars, but I am curious if anyone with expertise can comment on the clean room practices seen applied in this video. Is it odd that the workers don't have on full 'bunny' suits and have (what seems to be) a relatively large amount of skin/hair unprotected? I don't know if it matters that much, it just seems a little lax given the cost of failure.
Firstly, I've visited ISRO Bangalore(A few years back). And I did see the exact things you mentioned. I did ask the guy(Not sure, if he was the PR guy) who took our class for the tour. His answer was, they were likely assembling some test equipment and not the real equipment that was going to space.
(Which unlikely given parent's NYT article:)
The modest budget did not allow for multiple iterations. So, instead of building many models (a qualification model, a flight model and a flight spare), as is the norm for American and European agencies, scientists built the final flight model right from the start.
It's unclear whether the room is a climate and particulate controlled cleanroom up to the standards required for inplanetary probes, but they may (hopefully) do sterilization through chemical and heat treatments - but that alone isn't enough for planetary protection.
