"History has been created. This is a very proud full moment for all Indians. ISRO’S Mars orbiter Spacecraft has successfully enters Mars orbit. Aaj MOM ka Mangal se milan ho gaya, aur Mangal ko MOM mil gayi," Prime Minister Narendra Modi said congratulating scientists from the Indian Space Research Organisation (Isro) for putting India on the world map of space exploration and becoming the first to have a successful Mars mission on debut. In this article we share the successful journey of MOS from starting to ending.
