In exactly 1 month from now, on 24th of September, if all goes well, India’s Mars orbiter – Mangal yaan - will land. While it is great news and everyone is (and should be) proud of it, there are many people who are not really clear on what’s going on and what this mission is all about. I wasn’t all clear as I am, post this video.
This short, 5 minute video by The Curious Engineer explains it all in a concise manner.
For those interested in further details can find more information in the ‘about’ section of the video. Wonderful stuff.
The last part about expenditure for this mission – is it justified? is well articulated. (Quora thread on that here)
