00:02T-minus 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, ignition, and liftoff.
00:18Go back in.
00:19Go overall, 95.
00:23Vehicle is pitching downrange.
00:30M1D chamber pressures are nominal.
00:44At T-plus 30 seconds and counting, Falcon 9 has successfully lifted off from Space Launch
00:50Complex 40 at Cape Canaveral Space Force Station in Florida.
00:54The vehicle is now throttling down the engines to prepare for max Q.
00:58The point of telemetry nominal.
01:00Awesome.
01:01We're hearing that.
01:02We've got nominal telemetry there.
01:05We're just preparing for max Q, which is the point of maximum aerodynamic pressure.
01:10Falcon 9 is supersonic.
01:12Max Q occurs when the combination of speed and air pressure puts the greatest stress on
01:18the vehicle.
01:20Max Q.
01:22There's that call-up for max Q.
01:24Coming up, we have several major events in very quick succession.
01:28There are main engine cutoff, stage separation, second engine start, boost back burn, and
01:35fairing separation.
01:36Main engine cutoff, or MECO, is when all nine engines on the first stage shut down.
01:41This is followed by stage separation where the first and second stages...
01:47After MECO, we have stage separation where the first and second stages are pushed apart.
01:52Immediately after, the second stage engine will ignite to continue pushing towards orbit.
01:57This is also known as second engine start one, or SES-1.
02:02Shortly after that, the first stage will perform a boost back burn, putting it on track for landing,
02:06and then the two fairing halves will separate and fall away, as they are no longer needed
02:11to protect the payload once in space.
02:13We should hear the start of the call-outs in just about the next 10 seconds.
02:28Main engine cutoff.
02:30Stage separation confirmed.
02:34Main engine cutoff.
02:38Main engine cutoff.
02:41Stage 1 boost back startup.
02:44Main engine cutoff.
02:45And there we heard the call-outs for MECO, stage separation, SES-1, and the start of the boost
02:50back burn.
02:51turn.
02:52Coming up next, we will have fairing separation, where both of the sides of the fairings are
02:59going to fall off, and remember there that they are both flight proven.
03:03As a reminder, we will not be showing any views of stage two today at the request of
03:08our customer.
03:26There's the confirmation of fairing separation.
03:29Coming up, we should hear the call-out for boost back burn shutdown on Falcon 9's first
03:33stage.
03:36Stage one boost back shutdown.
03:40Confirmation of boost back shutdown.
03:42If you're just joining us, you're watching live coverage of the NRL-95 mission.
03:47To recap, Falcon 9 lifted off on schedule at 3.10am Eastern Time from Space Launch Complex
03:5540 at Cape Canaveral Space Force Station in Florida and had a successful stage separation.
04:00Up next, you'll be seeing the booster landing.
04:04In order to make its way back today, Falcon 9's first stage has two more burns to execute.
04:09First up is the entry burn, which helps slow the stage down as it re-enters the upper part
04:14of Earth's atmosphere.
04:15Then, following that will be the entry burn.
04:18The booster will initiate a landing burn, which will slow the vehicle even further for a soft
04:23touchdown at landing zone 2 at Cape Canaveral Space Force Station.
04:26The entry burn is set to begin around the T plus 6 minute mark.
04:35During the entry burn, Falcon 9 is decelerating by firing its Merlin engines in the direction
04:40it's moving.
04:40This causes the rocket to fly through the engine's exhaust gases, which deposits a layer of soot
04:45on the vehicle surface.
04:47This is what gives SpaceX's flight-proven vehicles their characteristic look.
04:51That soot comes from carbon-based fuel that Falcon 9 uses, and with each flight, that soot
04:56goes up a little more on the outside of the vehicle.
05:03Falcon 9 is still more than one minute away from the beginning of the entry burn.
05:10The booster is equipped with four hypersonic grid fins, which are positioned near the top
05:15of the first stage, and used for steering as it returns to Earth.
05:19These are the primary aerodynamic control surfaces for the first stage during atmospheric
05:24reentry and descent.
05:26Grid fins are a critical part of Falcon 9's reusability system.
05:31Reusability is key to lowering the cost of spaceflight, enabling more investments in critical
05:36space infrastructure.
05:37The Falcon 9 first stage that is supporting today's mission is performing this entry burn
05:42for the seventh time.
05:54Falcon 9 is moments away from the beginning of the entry burn.
05:58You should see the graphics light up as the engines do on the bottom of your screen.
06:27We should be just seconds away from an entry burn.
06:31You should see the Falcon 9 call out here.
07:01Stage one, entry, burn, start up.
07:04There's the call-out for the entry burn start-up on the Falcon 9 first stage.
07:09This burn is set to last about 17 seconds and again is slowing down the vehicle in preparation for its
07:15final burn and landing.
07:21Stage one, entry burn shut down.
07:24We just heard the call-out there for entry burn shut down signifying the completion of the first stage entry
07:29burn.
07:30Coming up next will be the first stage landing burn at about T plus 8 minutes.
07:47Stage two is in terminal guidance.
07:53This is the final burn the booster uses to reduce the- Stage one FTS is safe. Stage one transonic.
08:03Stage two STF is safe.
08:14Stage one landing burn.
08:19That call-out means this is the final burn this booster will see before landing.
08:25This final burn uses-
08:27This final burn uses-
08:27And back shut down.
08:37Stage one landing light deploy. Nominal orbit insertion.
08:45Stage one landing confirmed.
08:48There's another successful landing for Falcon 9.
08:52As mentioned at the top of the program we will not be showing any stage two or deployment views today
08:57at the request of our customer.
08:59It was October.
08:59Do you have to ask the question for the start?
