Did you count to 7? Everything is on board is OK, says the DDO. At 18, 36, local time and right on time, Aryan began her mission lifting off from the ground here in French Guiana beginning her first mission of the year. Rising into the clear skies over French Guiana, weighing 775 tons right now, she's burning 5 tons of fuel per second if you can believe that, 2.5 tons in each booster, and the core stage burning in additional 300 kilograms of fuel per second. She is following the program in the on board computer, which is located in the vehicle equipment bay, below the satellites, which gives all the orders, including stage separation. We will soon begin to see those. We're in the first of four flight phases for Aryan. On the first three are powered. The last is not. We'll describe each in turn. You can follow Aryan as she heads east across the Atlantic to separate the passengers over the east coast of Africa and over the Indian Ocean. Flight phases are right now, the main engine, and the two boosters are burning. Boosters are burning for another 20 seconds roughly. Then the main engine will burn alone for about 9 minutes. Then the upper stage will burn alone for about 16 minutes. Final flight phase, not powered, we'll get back to that when it happens. Basically, we're using the simple solid propulsion in the boosters to get off the ground away from the pull of the earth, and the more complex liquid propulsion cryogenics to obtain speed and performance. We're waiting for confirmation of the booster separation. You see that. Separate from the stages of acceleration to the power. There it is. The duty is just called out. You can see the two boosters falling away, leaving their vapor trail in the middle, is the core-state Aryan continuing to burn. Nice shots. All the parameters aboard are nominal. The boosters will fall 500 kilometers from shore in a protected area. Having done their job, we're now on the second powered flight phase, the main engine. The trajectories are normal. We're coming up on separation of the faring. Just before we do, take a look at the left. It's a hand side of your screen, the upper left. The cursor crawling up the line, that's actually two lines. The one is superimposed on another, the optimum trajectory and the real-time trajectory, as long as they're one and the same where we should be. Below that, two lines A and V. A is our altitude. You see we're climbing. V is our speed. We need between eight and nine kilometers per second to inject the seven lines. So watch the numbers. The DDO has just said that the faring has been jettison. That's coming right on time. The exposing Amathona's trace. Now you can see the black and blue box on the right. The faring protects the payload from shocks during Aryan's ascent through the atmosphere. We need the atmosphere at about 100 kilometers up. We don't need it anymore. And we can drop the weight, which is about 500 kilos. The core stage, basically a big propellant tank with the engine, it uses cryogenic propellant. You've heard that word before. Cryogenics offer certain advantages over-storeable propellant, which is the other option, namely better performance. They can also be turned off and on. And its motors can be reignited and can function longer. And we can see that with the upper stage, which is reignitable on the Aryan. And with the fourth stage called the Fricket with the Soyuz. Aryan one to four, previous models. Oh, they're success mainly to storeable propellant, not cryogenics. They're fuels that are kept in ambient temperature and don't evaporate. Like cold cryogenic does, and you saw that before lift up with the constant topping up. We needed storeable propellant is also cheaper. The cryogenics offer better performance. You can see Amathona's exposed to the elements. Below that is a black bell-shaped structure. That's the silver, the carrying structure inside of which is our second passenger. Next up, the latest in a series of profiles of space professions here at the Space Base.
