SpaceX’s five-hour launch window begins at 8:02 pm ET, and forecasters have give a 90% likelihood that the climate will probably be ok for liftoff. If all the pieces goes based on plan, that is what you need to see.

When the countdown clock hits zero, the Falcon 9 rocket will fireplace up its engines and roar towards area.

About one minute later, the rocket will hit “Max Q,” an aerospace time period that refers to the level throughout flight at which a car experiences its most dynamic stress.

Put merely: It’s when the rocket is shifting at very excessive pace, at a time when the environment continues to be fairly thick, placing numerous stress on the car.  

Two and a half minutes after launch, the backside a part of the rocket, the largest part that provides the preliminary thrust at liftoff, will shut down its engines — at second known as Main Engine Cutoff or MECO — and detach. That a part of the rocket, with most of its gas spent, will then head again all the way down to Earth for a pinpoint touchdown on a seafaring platform in order that SpaceX can refurbish and fly the rocket once more (All a part of the firm’s plan to save cash and make spaceflight cheaper.)

Meanwhile, the second stage of the rocket, nonetheless connected to the crew capsule, will fireplace up its engine and proceed accelerating quicker and quicker till it spends its gas and reaches orbital velocities — or greater than 17,000 miles per hour.

About 12 minutes post-liftoff, the second stage will detach from the crew capsule.

What’s left of the rocket will probably be discarded in the ocean, whereas the Crew Dragon capsule and its 4 passengers will start its three-day free-fly by way of orbit.

All the intense G-forces will probably be over, and the crew will probably be weightless. The tip of the capsule, known as the nosecone, will open to disclose a big dome-shaped window. And the capsule will use its onboard thrusters to orient it into the right orbit.
