ISRO is about to script history and everyone wants to know the answer to this question: Where is the Gaganyaan mission going? Well, the Gaganyaan mission is all about going to space and taking 3 astronauts along in a spacecraft. During the test, the rocket will ascend to an altitude of nearly 17 kilometers before triggering an abort signal. Before the Gaganyaan mission does that, ISRO is testing its crafts and systems deployed so that if something goes wrong, the Indian astronauts can be saved. And that is what the Gaganyaan mission test flight launch is all about.
