ฝึกพูดภาษาอังกฤษด้วยเทคนิค Shadowing จากวิดีโอ: Starship Flight 14 Goes Orbital! SpaceX Reveals 10-Hour Mission | Starship Update

SpaceX has finally shared the mission profile for Starship Flight 14, answering some of our biggest questions.

Will Starship be heading to orbit?

How long will it stay there?

And where is ship going to come down afterwards?

And if that wasn't enough, SpaceX also dropped their next docuseries episode, Holy Grail of Rocketry, sharing the journey of Ship 40 so far.

And it's a pretty good one.

From Florida Space Coast to South Texas, we'll be covering all of that and more on this week's Starship Update.

The End Starting off this week, we saw yet another delay for Flight 14.

NOTAMs and NAV warnings now show the earliest targeted launch date as September 28th.

SpaceX themselves has also listed Flight 14 as no earlier than or net September 28th, pending regulatory approval.

These delays are likely due to the FAA not yet having

issued SpaceX the launch license required for the Flight 14 mission profile.

SpaceX already has a launch license for the same flight profiles that we've seen on previous missions, with a splashdown targeting the Indian Ocean.

But SpaceX wants to send Ship 41 to orbit, something they have never done before, and that requires a new launch license.

This license must approve not only going into orbit, but also performing a de -orbit burn.

And that's a big deal on its own.

SpaceX has deliberately chosen suborbital trajectories to this point to avoid

leaving a Starship -sized piece of space junk floating uncontrolled in orbit, in a worst -case scenario, which also meant reduced risk.

They have never had to worry about an accurate diorbit burn before.

If they had, and that diorbit burn was not successful, Starship could come down in a populated area.

Starship is, of course, designed to survive re -entry, after all, so that would certainly cause a lot of problems here on the ground.

That's a good enough reason alone for the FAA to be

absolutely sure an orbital flight of Starship will not pose a threat to the general public.

The FAA also has to approve the additional re -entry locations as well.

You may have already heard of our breakdown of the environmental assessment for the landing sites, which the FAA has already approved.

But that still does not mean SpaceX can use those sites. Yet.

The FAA still has to include those in the launch license.

Let's have a closer look at the mission profile itself.

If the flight goes as planned, an almost 10 -hour mission profile would be performed, during which, Ship 41 will make approximately six orbits around Earth.

Ship 41 will fly at 275 kilometers in altitude

and stay there until it de -orbits for a targeted splashdown off the coast of Chile in the Pacific Ocean.

Thankfully, SpaceX also plans to live stream the entire flight.

One of Starship's main objectives here is to deliver the first 26 operational Starlink version 3 satellites into orbit.

If you're at all familiar with Falcon 9 Starlink missions, which we certainly are, you'll know each mission has a shell number attached to it, along with that shells at designated flight.

This will be no different.

Welcome to Starlink Group 31 -1.

After a successful orbital insertion burn, Starship will deploy these satellites starting at T plus 34 minutes and 9 seconds, and wrapping up at around T plus 1 hour,

4 minutes and 41 seconds.

All of these times, though, are approximate.

These satellites will come out one by one from the PEZ dispenser, as we have seen on previous test flights of Starship.

Deploying them one by one will also separate them from each other and lessen the Starlink train visual, because they are not all released at once.

The Version 3 satellites themselves are no slouch.

Ship 41's payload of Version 3 satellites alone will increase network

capacity 10 times compared to a full load of Version 2s on a single Falcon 9 mission.

Each Version 3 satellite will add 1 terabit per second of data transfer to the Constellation.

For comparison, a gigabit fiber connection to your home carries a thousand times less data per second.

After deployment, the Starlinks will then deploy their solar arrays and attempt to contact the ground and the rest of the constellation.

And that was actually already tested on the previous flight when SpaceX also deployed real version 3 satellites, which had good comms where needed.

Those satellites, however, flew in the exact same suborbital trajectory and re -entered with Ship 40.

And while Ship 40 did make it to the Indian Ocean, as we know by now, these satellites burned up in the atmosphere.

After they establish connection, they will start rising to their operational orbit via their onboard thrusters.

But before they begin that, three of the satellites have been modified to perform a visual inspection of Ship 41's heat shield, as we've also seen in the past two flights.

However, there's something worth mentioning here, though.

Before Starship even reaches orbit, SpaceX will initially be sending Ship 41 into a suborbital trajectory targeting the Indian Ocean once again.

But hang on a second, we just spent all this time talking about sending a ship into orbit.

What's this all about?

Orbit will only be achieved if SpaceX pulls go for an orbital insertion burn at T plus 25 minutes and 28 seconds, lasting for about 18 seconds.

Then, and only then, can Starship reach orbit for the first time.

If they find something awry in the data beforehand, or if something worse goes wrong, they have the fallback of letting Starship splashdown in the Indian Ocean.

It's just a safety net, folks.

Once Ship 41 is in orbit and the Starlink satellites are on their way, ship will then begin its coast phase.

One hour after the insertion burn, SpaceX will then perform an early contingency check.

With that done, they can then decide whether the ship is healthy enough to stay in orbit

or if they should deorbit early for a contingency pacific splashdown.

Seven hours after insertion, SpaceX will perform another checkout before the planned Europa burn nine hours after orbital insertion.

That burn will use a single sea level raptor engine like the in -space relay test

that we have seen on previous flights.

Some of the health markers that SpaceX will be watching are with the raptor engine specifically.

Without them, Starship does not make orbit.

And without them, it doesn't come back.

Well, at least controlled.

Other watch items include loss of power, communications, structural integrity of the ship, and making sure all the hardware on the ship is in nominal condition and functioning properly.

Stuff like engine feed lines, valves, amongst others.

There are more than 500 physical sensors in the ship.

If even one of those markers raises a concern or developing issue, SpaceX will try to bring the ship back while keeping the public safe.

Even if every system is green, SpaceX will not be sitting on their hands during the coast phase.

Because this flight is designed to last a lot longer than any previous Starship mission before it, more systems can be tested in orbit.

Lessons learned here will directly feed back into designing future ships.

One of the most important long -term pieces of the entire Starship puzzle is in -space refilling.

SpaceX needs to know how long it can keep propellant in orbit without having to worry about propellant boil -off.

With more time in space, temperatures and pressures inside the tanks can be monitored to better understand boil -off conditions.

And that's with this design, including the header tanks.

Data gathered here will also help SpaceX dial in the numbers

for how many tanker flights an HLS mission will need to land humans back on the moon

and return them safely to Orion.

But all of that to be said, though, I'm not trying to let the booster feel left out here.

Booster 21 received modifications based on Booster 20's performance on Flight 13, aimed to improve filtering to the engines, plus software changes to enhance relight reliability.

It's also aiming for a soft splashdown in the Gulf of America.

If both Booster 21 and Ship 41 succeed in hitting their targets in all areas, we might see SpaceX trying to catch both Booster and Ship on Flight 15.

This flight will not just celebrate Starship deploying the first Starlink version 3 satellites into an operational orbit, but it will also mark a huge leap forward,

not just for the Starship program, but for bringing humanity back to the moon.

So success on flight 14 is crucial.

But if you want to fly rockets, you first have to build them.

Over at the production site in Omega Bay 1, the forward section of Booster 23, which also contains the integrated hot staging ring, rolled out this week.

Only the final section of the methane tank remains.

SpaceX already has another complete booster sitting in the Mega Bay together with Booster 21 and Booster 22.

After that, Booster 23 will have its autogenous pressurization lines installed, plus electrical work and other bits, before it heads to Massey's for cryogenic proof testing.

Speaking of Booster 21, on Sunday, a road closure was posted for its roll to the pad.

Later that day, the booster appeared outside Mega Bay 1 on a transport stand, and several hours later, the booster rolled to pad 2 for what is likely to be its final journey before flight.

100

Now we're waiting on a road closure and roll of its flight partner, Ship 41, likely in the next day or two.

101

Booster 23's likely flight partner, Ship 43, was fully stacked this week.

102

Its aft section rolled from Star Factory into Mega Bay 2 and was picked up by the bridge crane.

103

With the last section hanging underneath Ship 43, it was placed onto the turntable and welded to the rest of the vehicle.

104

The stacking process is complete, but it's not ready for cryo testing just yet.

105

Just like Boosters, a ship still needs its autogenous pressurization lines installed amongst electricals and other hardware.

106

The aft flaps will also be installed before heading to Massey's.

107

And we actually caught delivery of these aft flaps this week, covered in white shrink wrap to protect them during transport.

108

While it's still some time away from taking over the job of both megabays, Gigabay has also made progress this week as well.

109

During construction, we will also see more work stands and turntables built and moved into Gigabay's work cells.

110

The bridge crane for Gigabay has also not yet been lifted into place.

111

Just as we have seen with the roof sections though, SpaceX tries to mount as much hardware onto it as possible before being lifted.

112

That's because you have better access to it while everything is still on the ground, which makes the whole process more efficient.

113

But if the news about Flight 14 so far wasn't exciting enough for you, SpaceX also dropped its third episode in their Starship docuseries.

114

In this episode, named Holy Grail of Rocketry, SpaceX went over Flight 13 as a whole, with appearances by both Falcon and Grasshopper.

115

We learned that during the terminal phase of Booster 20's boost back burn, the Center 3 Raptor engine showed signs of ice clogging, which caused Booster 20 to end the burn early.

116

Not to be discouraged, it then tried to ignite 13 engines for its landing burn.

117

But in the end, it only managed to light 8 and then down to 5, failing to slow the booster enough for a soft splashdown.

118

If you recall last week's episode...

119

When we saw Booster 23's aft section rolling out to Mega Bay 1, we noticed it had some mounting hardware for ice filters.

120

This is one of the modifications SpaceX has made to improve the booster design

121

and make sure it can safely reignite its Raptor engines without starving them of propellant.

122

But with these lessons learned by now, do you think Booster 21 will finally make a soft splashdown of the Gulf?

123

Let us know in the comments section down below.

124

But let's not ignore the star of the episode, that being Ship 40.

125

We learned that a safe splashdown and tipover of Ship 40 was secretly not the main objective.

126

While it is true that SpaceX had made plans in the past for recovering a ship from the Indian Ocean, previous ships had all exploded when they hit the water.

127

So actually recovering Ship 40 was not in the forefront of SpaceXers' minds at the time.

128

They were actually caught pretty far off guard by this, and it was kind of funny.

129

SpaceX then immediately got down to business.

130

As Justin Steyer put it, we're gonna start getting scrappy.

131

At first, they tried to bring Ship 40 to mainland Australia before diverting to Christmas Island, as we all know by now.

132

The decision was then made to bring Ship 40 back to Starbase with the help of the vessel Forte.

133

At the time, there was still a lot of uncertainty.

134

Once SpaceX knew Ship 40 wasn't going to explode and was safe for crews to approach, they recovered some TPS tiles from Ship 40,

135

two of which will be reflown on Ship 41 to prove tile reusability, which is kind of insane, actually.

136

If you want your ship to come back to Earth in one piece for reuse in the future, the thermal protection system needs to be optimized for such a task.

137

But the heat shield does more than handle re -entry heating, though.

138

On ascent, and again on re -entry, air and plasma are actively searching for a path around the tiles as they flow by.

139

Try to get underneath them and pull them off.

140

But if a tile blows off, the area covering it is protected only by an ablated material, which is not reusable.

141

This was also a problem during the shuttle program, where tiles could fall off on ascent and leave the vehicle vulnerable during re -entry.

142

And even more so then, actually, because the orbiters had an aluminum frame and starships are made of steel.

143

With lessons learned from previous flights, SpaceX had ID'd some of the areas more prone to tiles falling off, and addressing that by adjusting the flow path of the air and plasma.

144

Curved tiles produce heating in the gaps between tiles, and also keep them from coming loose.

145

In addition to this, SpaceX is also using different retention mechanisms in the affected areas.

146

Thanks to Ship 40, SpaceX Director of Thermodynamics, Mauro Prina, said they can improve the ship design at least three months earlier than he originally thought.

147

At the end of the episode, SpaceX said that if there was a tower at the landing site during Flight 13, Ship 40 would have been caught.

148

With Ship 40's pinpoint landing and Ship 41 going to orbit, do you think SpaceX will be able to catch a ship on Flight 15?

149

Let us know in the comments.

150

I certainly hope so.

151

We've been wanting to see that for quite some time now.

152

Let's head over to the Space Coast and check in on progress at the Starship facility at Launch Complex 39A.

153

During the week, we saw the ship quick disconnect arm extended.

154

And last week, we saw the Buckner LR11000 attach and reattach to the arm.

155

This was likely for SpaceX to install the structural testing water bags.

156

And this extension could be SpaceX placing the SQD back in its resting position.

157

The same LR11000 crane was also lowered and then raised again during the week, likely for post -lift operations.

158

Last week, we discussed hardware from the Space Coast being loaded onto a barge bound for Starbase.

159

That included a horizontal ship transport stand, a booster work stand for Gigabay, and a section of the orbital launch mount top deck for Pad 1.

160

These arrived at Starbase on September 17th.

161

Although not much activity was spotted here this week, bar the tank farm getting venti, we can deduce that it is nearly complete and undergoing final preparations.

162

Depending on how Flight 14 and 15 progress, we could still be on track for Pad 39As for a Starship launch before the end of the year.

163

Now, y 'all, I know Pad 37 does not get much mention in these updates, and that's because progress here is a lot more difficult to keep track of

164

but we may be in the air again hopefully soon to get eyes on it once again and track progress.

165

Over at the launch site in Starbase, SpaceX is continuing preparations for Flight 14 at Pad 2 while also progressing on the modifications and retrofit to Pad 1.

166

We also saw two deluge tests at Pad 2.

167

On September 14th, SpaceX conducted a full deluge test that simulates flow rates used for launch.

168

They also ran one that used the top deck and ridge cap, which would be used during liftoff and booster catches.

169

The company has completed a wide array of these tests in recent weeks in preparation for Flight 14,

170

but also plenty before then to really nail down its operations to best protect Pad 2 infrastructure during launch.

171

Also on Pad 2 this week, we saw workers sandblasting the orbital launch mount and working on the base of the tower.

172

These are pre -flight activities to get the orbital launch mount and tower into optimal condition before Flight 14.

173

Sandblasting the orbital launch mount clears away any carbon soot, scorched ablative coating, and rust.

174

This process lets technicians inspect structural wells thoroughly and apply new thermal protection ahead of Flight 14.

175

Workers were also spotted on a man lift inspecting or working on the ship quick disconnect.

176

This crucial infrastructure allows the ship to be filled with propellants.

177

As we saw during testing of Ship 42 with the Chop6 and SQD last week, it will also drain and save the vehicle once caught.

178

Besides propellant transfer...

179

the SQD also feeds power and transfers data to the vehicle until it launches.

180

Over at Pad 1, the OG, on September 13th, we spotted hundreds of concrete trucks arriving at Pad 1 for a massive flame trench pour.

181

Next, SpaceX will likely begin to pour the slopes of the trench.

182

But this process is normally done in stages to prevent it from slumping or collecting at the bottom.

183

Once complete, the flame bucket assembly will commence inside the trench with structural supports and then the actual flame diverters themselves.

184

This will mark the completion of the flame trench

185

and will be followed by the orbital launch mount rolling out

186

to the pad to be installed on top of the reinforced concrete pillars.

187

During the week, we had views of the flame buckets under construction.

188

Although we didn't spot any work actively underway, SpaceX could be drilling holes into the structure to allow water flow.

189

The bidirectional flame diverter splits the exhaust from all 33 Raptor engines during liftoff and minimizes damage to the infrastructure.

190

Let's close this week out with our McGregor Minute.

191

During the week, we saw a total of 16 burns at McGregor, ranging from all three Raptor test stands.

192

The Vertical Stand, Raptor North, and Raptor South.

193

The burns lasted anywhere from 30 seconds all the way up to 256 seconds in duration, about on par with what we normally see.

194

Last week, we saw the first test from Raptor South since July 26th.

195

And they didn't stop there, as multiple other burns were also observed here this week as well.

196

The Raptor North and South stands are horizontal in orientation

197

and used to conduct the initial checkouts of Raptor engines before they perform long duration, flight -like use at the Raptor vertical stand.

198

Speaking of, we saw a total of nine burns there this week, one of which lasted for 245 seconds in duration.

199

This is close to what a ship -assigned Raptor engine would experience in the real world.

200

16 observed tests this week showcased McGregor's high throughput capability as SpaceX scales engine qualification to match ship and booster production.

201

Running engines on all three stands at once lets technicians finish horizontal acceptance test quickly, while the vertical stand handles full duration qualification burns.

202

Alongside test firings, our cameras also spotted several Raptors being moved about.

203

Amongst these looks like Raptor number 246, which would currently be the highest serial number recorded Raptor 3 seen so far.

204

With Flight 14 almost being a week away, will the FAA give them a launch license in time?

205

Let us know in the comments section down below.

206

I'm Max Evans from NSF.

207

Thank you so much for watching and I'll catch you guys next time.
