Once afterwards go Good morning from the Space six test cast studio at our headquarters in Hawthorne, California I'm John is broker, and I'll be bringing you commentary on today's first test flight of the crew Dragon spaceship.

Today's test is the pad abort test taking place from our launch pad at Complex 40 on Cape Canaveral.

It's currently just over 14 minutes until a planned launch time flight is scheduled to occur at 9 a.m. Eastern daylight time or one PM Universal time.

Weather appears to be acceptable, but we continue to watch cloud levels and possibility of lightning in the area.

Today's window extends several hours, though, so if we have a weather problem or other schedule issue, we should have time to be able to take a crack at a launch at a later time space.

I've conducted a successful static fire of the spaceship yesterday on the fifth of May.

Following a review of the data from that test, the Space six launch director gave the go to proceed with today's flight.

Most recently, we've done the Dragon radio frequency checks it just over half an hour before launch, and we have gone into final configuration for flight AT T minus 25 minutes.

With that, let's listen to the launch conductor poll of the team A team minus 13 minutes all stations going to go for terminal count, beginning with mission Assurance.

You've heard Launch conductor pull the team for their readiness for test coming up just over 11 minutes and 45 seconds from now.

Launch Director is looking at one possible constraint you heard?

They're looking at the, uh, charged atmosphere around the launch complex.

The lightning concern that I talked about earlier.

They're evaluating that right now, so we should hear some more shortly.

If we go into the terminal count sequence leading down to zero and we do have to hold, then we'll just recycle back to possibly around T minus 20 minutes, evaluate conditions and then attempt again.

So let's listen into the countdown net on and see if we continue into terminal count.

If a hold is called from this point forward, the terminal count auto sequence will be aborted indicating a board or hold condition by saying hold, hold.

Hold on the primary countdown That countdown one In this event, the D.

Will immediately abort the auto sequence.

The D C shall not aboard the auto sequence after t minus 10 seconds and operators shall not call a hold after t minus 10 seconds.

If they hold is called all operators, proceed to the contingency terminal count.

We're t minus eight minutes in 19 seconds until the test of the first true dragon.

Today's flight is part of space Sexist commercial crew contract with NASA It's the first flight test of the launch abort system featuring the use of the eight Super Draco thrusters.

Today's test will be short in duration following a terminal countdown which were in the middle of right now Dragon will fire its launch abort system.

All eight super drake of thrusters will ignite for five seconds burning the nitrogen tetroxide and hydrazine rocket propellant.

This will carry the dragon capsule and its trunk away from the launch pad, simulating an abort from a launch vehicle.

The eight engines, built by Space six will generate £120,000 of thrust over half a 1,000,000 Newtons of force in five seconds.

The trunk and capsule will be a kilometre above the pad, heading out to an offshore landing in the Atlantic Ocean.

Dragon will coast for another 16 seconds in a tea plus 21 seconds, the trunk will be jettisoned from the capsule.

This frees up the crew dragon capsule to rotate and pointed seat shield towards the ground.

The heat shield, as on our cargo dragon flights is protected by the trunk until it is jettisoned 25 seconds into flight.

The drogue parachutes will be deployed, followed by the main parachutes at 35 seconds into flight.

Then finally, dragon should splash down just offshore from the launch pad.

In approximately one minute and 47 seconds after launch, splashdown will be about 2.2 kilometers from the pad.

Now, this is the first test is I said of the space six crew Dragon spaceship.

We're not carrying people on this flight.

However, there is an instrumented dummy on board which will allow us to collect data on forces experienced during the flight.

This data combined with the instrumentation throughout the crew Dragon vehicle help Space six ensure the safety of human passengers on our future missions.

Currently, we're coming up on T minus six minutes.

Dragon spacecraft has begun the transfer to internal power.

We've also heard that the weather constraints are go for the test coming up right at the top of the hour.

So with that, we're going to go back and listen into the countdown.
