SpaceX, Falcon 9, Rocket 🔴 SpaceX Falcon 9 Rocket Launches Starlink Mission V1.0-L21 with 60+ Satellites 03/14/2021

Two one zero ignition and lift one vehicles pitching down range. My proportions, as you can see, falcon 9 has successfully telemetry nominal falcon 9 has successfully lifted off from pad ‘a at kennedy space center carrying our stack of starling satellites to orbit we’re gon na throttle the nine merlin engines down in preparation for max q, supersonic or Maximum aerodynamic pressure – this is the largest structural load that the vehicle will see during ascent, so slowing it down a little bit will help the vehicle pass through that short period max cube there. We heard the call out for max q now in about a minute we’re going to have three events happen in quick succession back to back the first one is main engine cutoff or miko. This is where all nine of those m1d engines are going to shut off and that’ll help slow the vehicle down in preparation for the second event stage separation, as the name would suggest. This is when the first and second stages will separate from these from each other. The first stage will start its way back to earth. We heard the chillin we’re flowing some super chilled liquid oxygen into the turbo pumps on that second stage. Engine uh, the first stage after stage separation, will make its way back to earth. Second stage will continue its journey with the third event scs 1 or second engine start one. This is where mvac will light up and begin to propel.

Second stage, along with the starlink satellites into orbit and main engine cutoff will be coming up in 10 seconds. Everything continues to look nominal there with that vehicle trajectory and mikko stage. Separation confirmed all right there on your screen and throttle up complete, as the mvac nozzle begins to develop that bright glow. We can see that all three events like i said, quick succession on the left hand side of your screen. We have the first stage in the background behind the first stage. I absolutely love this view. We got some nightlights of the space coast behind it. The first stage is actually separation confirmed uh. They were heard the call out for fairing step, and we can see that stack of sterling satellites there great views everything looks nominal there with our second stage as it heads towards its targeted drop off orbit. First stage is going to execute two burns in order to make its way back to earth. If you look closely, you can still see the night lights of the space coast there in the upper left corner. The first of the two burns that first stage will execute is the entry burn where three of the m1d engines will reignite. This will help to slow the stage down, as it re enters the upper part of the earth’s atmosphere. The second burn is the landing burn. This is a single engine burn that brings the vehicle speed. It brings the speed down rapidly in order to land on the drone ship.

So there are both shots that we have on screen are actually both of the of the second stage. We can see the large plume on the left hand, side. Everything continues to look nominal so there we can see that second stage vacuum engine. This engine will power the second stage to its targeted orbit. What you can’t see on screen is the other end of the second stage where the 60 sterling satellites are stacked and awaiting deployment. Later on. In our mission this morning, starling satellites operate over 60 times closer to the earth than traditional satellites resulting in much lower latency. For those of you that might not be familiar, latency is the time that it takes to send data from one point to the next. So in this context, it’s the time it takes to send data just following a nominal trajectory good call out there for nominal trajectory. For second stage um, so latency in this context, it’s the time that it takes to send data from the ground to the satellite and then back when satellites are far away from earth. Latency is high, we’re talking 550 milliseconds or more. This prevents activities like video calls and online gaming when satellites are close to earth like the starling satellites, latency is low more like 20 to 40 milliseconds versus 550 milliseconds. This enables video calls and online gaming with an experience similar to fiber or cable and because starlink is a satellite network, you’re not limited by ground infrastructure that’s.

One of the main reasons why people who live in rural or remote areas, don’t have access to high speed internet because running the fiber or the cable necessary to get them connected is just too expensive. The starlink kit comes with everything you need to get connected, including your starlink, also known as dishy mcflatface, your wi fi, router, power supply and cabling. The hardware comes pre connected in the box, so all you have to do is download the starlink app plug it in find the best install installation spot for your dishi and you can get connected to fts is safe. You can get connected to the internet in a matter of minutes stage, one entry burn startup and there we can see on your screen startup of that first of two burns. The entry burn this lasts 20 seconds. As i mentioned earlier, we have reignited three of the nine merlin engines at the base of the first stage vehicle stage. One entry burn, shut down and shut down of those three engines. So the reason we perform the entry burn is we want to slow the first stage down as it reenters the earth’s atmosphere. As you can tell by the energy there on the grid fins, we can see that it’s going pretty fast and we want to slow the velocity down as it reenters the atmosphere on a nominal trajectory. I heard the call out there that second stage is on a nominal trajectory.

The next event that we have coming up will be the landing bird for the first stage, as the name suggests. This is when we’ll be attempting to land on our drone ship. Of course, i still love you, which is currently holding position. Uh uh a couple hundred miles off the coast of florida in the uh transonic a couple hundred miles off the coast of florida in the atlantic ocean. Everything continuing to look good with the second stage and our sterling satellites signal stage. One cape canaveral expected stage, one landing burn, so we heard the call that the landing burn four stage one has begun. We can start to see the plume there on our drone ship cam. On the left hand, side of your screen, hopefully we’ll, be able to maintain video signal through landing landing leg deploy. Okay, the landing legs are out terminal guidance uh. Unfortunately, it looks like we weren’t able to maintain that video signal. We’Ll we’ll bring that back to you as soon as we can, as well as a status update on that landing. Everything continues to look good. Fts is safe. Everything continues to look good there with second stage stage. One landing confirmed all right. We heard it, we couldn’t see it, but we did hear verbal confirmation that we had a successful landing of that booster marking our seventy signal stage.
