The reality is that ISRO has managed to put a satellite into Earth orbit, an accomplishment while admittedly complex isn’t exactly groundbreaking. Mangalyaan has only just begun its long journey to Mars. Which is not to say that it won’t make it, but there are numerous aspects which could go wrong between now and next September, when it is expected to reach Mars orbit. China and Japan had similar missions that went horribly awry after spending significantly more time and money. The much-vaunted Chandrayaan mission as well, had significant attention showered on it at launch which eventually faded away. The fact that it failed to meet design requirements is barely known among the general public.
