During my last period I was bored because had nothing to do so I watched the Falcon Heavy test launch on youtube. When I was done I was curious so I looked up its launch profile but could not find any mention of a prograde burn which made me look at all the other rockets such as the Saturn V, Gemini Launch, Ariane 5 and still could not find the slightest hint at a circularization or prograde burn. Any ideas on why? This is driving me insane!
