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.

I think it is a Class 100,000 cleanroom (where not much precautions are taken) rather than Class 1 or 10 wherein typical lytho processes happen. The inner assembly must be done in Class 10 cleanroom, and I do not think so they will show a video of it publicly. Btw gloves, shoe covers, face mask, hair protection, safety glasses are also "missing".
