FLEET DEPLOYMENT

Nominal deployment programme

Compared to the last quarterly update in October 2021, the entry into service of KONNECT VHTS has been delayed from the first half to the second half of calendar 2023. Furthermore, while still expected within the H1 2023 window, the entry into service of the EUTELSAT 10B satellite has been delayed versus our previous expectations. This reflects the impact of both manufacturing delays and their knock-on effects, including pairing difficulties, related to launch rescheduling, in the context of global Covid crisis.

All other data remains unchanged.

Cross-post:
NextSpaceFlight lists a launch with a satellite for Eutelsat in November that will expend B1049.

Based on the Eutelsat launch schedule this could be any of 10B, Hotbird 13F, Hotbird 13G.  All of them are electric propulsion and due to enter service in either H1 2023 or Q2/Q3 2023.

More regarding the launch of a Eutelsat geocom satellite aboard an expendable Falcon 9.
 Hotbird 13G?  Not Eutelsat 10B.
Intelsat made some FCC ground station filings to support LEOP of "Hotbird F1", which isn't actually a real name.  I'm guessing that should be Hotbird 13F.  The launch date given is October 17.  [Filing dated August 15.]
Wouldn't Hotbird 13G be more likely? The plan seems to be for it to launch before 13F (based on the table a few posts above).
Could be 13G
It may also be that Hotbird 13G gets the better orbit, i.e. an expendable Falcon 9.
With Hotbird 13G, Eutelsat wants to get the money for the EGNOS payload as soon as possible.
A total of 100 million euros in 15 years.
Hotbird 13F is not so urgent, but should also be launched this year.
<snip>

Edit: Might 10B launch on another Falcon 9?  If so, NLT early 2023?  Ovzon-3 is launching on Ariane 5.

Ovzon-3 news:
SN Maxar receives delayed Ovzon 3 satellite parts, August 18

TAMPA, Fla. — Ovzon’s first satellite is set to launch between December and February following the delivery of parts caught up in supply chain delays, the Swedish broadband service provider said Aug. 18.
<snip>
<snip> Ovzon CEO Per Noré said Ovzon 3’s size makes it easier for Arianespace to work the spacecraft into an existing launch manifest [Ariane 5].

PRESS RELEASE - 29 OCTOBER 2019 08:34

Eutelsat orders EUTELSAT 10B satellite for inflight and maritime connectivity services

Incremental HTS Ku-band capacity addressing demand in mobile connectivity
Substantial firm commitments from leading in-flight connectivity service providers
Ensuring service continuity for customers on EUTELSAT 10A
Paris, 29 October 2019 - Eutelsat Communications (Euronext Paris: ETL) has signed a letter of agreement with Thales Alenia Space for the procurement of EUTELSAT 10B, a new all-electric satellite built on the Spacebus NEO platform. Scheduled to be launched in 2022, the satellite will be located at 10° East, an orbital position that offers a unique visibility spanning from the Americas to Asia. It will ensure service continuity for existing customers on EUTELSAT 10A, while supporting the development of the Group’s activities in mobile connectivity thanks to two new incremental HTS payloads.

Two powerful and innovative payloads to provide inflight and maritime connectivity

Responding to strong growth in demand for mobile connectivity, EUTELSAT 10B will carry two multi-beam HTS Ku-band payloads: a high-capacity payload, covering the North Atlantic corridor, Europe, the Mediterranean basin and the Middle East, offering significant throughput in the busiest air and sea traffic zones, and a second payload to extend coverage across the Atlantic Ocean, Africa and the Indian Ocean. The satellite’s HTS payloads will be able to process more than 50 GHz of bandwidth, offering a throughput of approximately 35 Gbps.The entire satellite payload will be digitally processed, offering capacity allocation flexibility thanks to a digital transparent processor.

Firm capacity commitments

Firm multi-year capacity commitments have already been secured with several leading in-flight connectivity service providers, representing more than one third of the incremental HTS capacity. These partners will rely on EUTELSAT 10B to provide airlines with in-flight connectivity services.

Service continuity at a key orbital location
The 10° East location that EUTELSAT 10B will occupy has been operated by Eutelsat since 1987 and provides unrivalled coverage in the heart of the European, Middle Eastern and African zones. EUTELSAT 10B satellite will carry two widebeam C- and Ku-band payloads, totalling 32 [1] to ensure continuity of the missions of the EUTELSAT 10A satellite, whose operational life is scheduled to end in 2023.

The capital expenditure represented by EUTELSAT 10B does not alter Eutelsat’s existing envelope of 400 million euros per annum on average for the period from July 2019 to June 2022.

Rodolphe Belmer, CEO of Eutelsat, said: "The procurement of EUTELSAT 10B underpins our strategy of focusing our development in the field of connectivity. The selection of its Ku-band payload, in complement to the future KONNECT VHTS operating in Ka-band, reflects our ability to serve our customers in both Ka- and Ku-band with best-in-class space assets. Firm capacity commitments secured with major partners testify to both the quality of coverage at our 10° East location as well as the robustness of demand in the mobile connectivity segment.”

Eutelsat entrusts Arianespace with the launch of its next-generation EUTELSAT 10B satellite

December 15, 2020

Arianespace and Eutelsat have confirmed that EUTELSAT 10B, Eutelsat’s next generation high-throughput telecommunications satellite, will be launched on an Ariane 5 rocket.

EUTELSAT 10B is scheduled for launch in 2022 on one of eight Ariane 5 missions remaining to be performed with the heavy-lift launcher.

Arianespace, the European launch services provider, has confirmed that it will launch a new satellite – EUTELSAT 10B – for Eutelsat, one of the world’s leading satellite operators.

The launch is scheduled from the Guiana Space Centre on an Ariane 5 in 2022.

EUTELSAT 10B is a telecommunications satellite to be positioned at the 10° East orbital position, offering unique visibility spanning from the Americas to Asia. Built by Thales Alenia Space and based on its Spacebus NEO all-electric platform, it will embark Ku- and C-band payloads to ensure service continuity for existing customers on EUTELSAT 10A, while supporting the development of the Eutelsat Group’s activities in mobile connectivity thanks to two incremental multi-beam HTS Ku-band payloads.

Pascal Homsy, Eutelsat’s Chief Technical Officer, said: “We are pleased to entrust the launch of EUTELSAT 10B to our long-standing partner, Arianespace, further cementing the relationship between our two companies and reflecting our confidence in Ariane 5 providing us with access to space.”

“We are honored by Eutelsat’s renewed trust in Arianespace’s launch services solutions,” said Stéphane Israël, CEO of Arianespace. “Not only does this contract illustrate the long-lasting partnership between our two companies and the robustness of our relationship, it also demonstrates the competitiveness of Ariane 5 within the demanding market of geostationary telecommunications satellites. With this latest announcement, Ariane 5 has secured almost all its final series of launches, in advance of the handover to Ariane 6 with the same success.”

For quite a while, we have been told that 1049 was being reserved for the next mission with a deliberately-expended booster, and this is why it has not flown for a long time. It is the earliest of the active boosters and is reputed to lack some more recent design changes that simplify refurbishment. Has something changed?

The potentially expended booster might indicate this is the launch with HAKUTO-R Mission 1.

For the first time in over 3 years SpaceX will expend a Falcon booster on purpose. But it's not just one, it'll be three boosters. If schedules hold, the order will be B1066, then B1051-14, and finally B1049-11.

B1049-11 is a Falcon 9 booster that will fly on the Eutelsat 10B mission. Among its flights, this booster supported the first launch of Starlink satellites in May 2019. Its last flight is part of a previously unannounced three-mission deal with Eutelsat.

Quote
It'll be sad to see these three boosters go and it's been a long time since SpaceX intentionally expended one but at least they'll go out doing just what Falcon does best... which is putting stuff into orbit.

October 16 update; no mention of Eutelsat 10B; launch is apparently after Eutelsat Hotbird 13G and HAKUTO-R:
https://www.launchphotography.com/Launch_Viewing_Guide.html
Quote
A Falcon 9 will launch the Hotbird 13G communications satelite for Eutelsat from pad 40 on November TBD. A Falcon 9 from pad 40 will launch the HAKUTO-R lunar lander for iSpace on November TBD. The first stage will land back at the Cape about eight minutes after launch. And a Falcon 9 from pad 39A will launch the Dragon CRS-26 resupply mission to the ISS on November 18 around 4 or 5 p.m. EST.

I would have nothing against a European law forbidding purchase of launch services out of Europe, but then you have to accept the consequences if the European launchers are grounded.

TAS kept its word and delivered the Eutelsat 10B on schedule.
Apparently, Arianespace cannot fulfill the launch contract concluded with Eutelsat (the best customer!) on schedule.
The circumstances are difficult, of course, the time pressure, solo launch of Konnect VHTS due to the delay of Ovzon-3, the limited number of Ariane 5, the Ariane 6 delay...
But the decision not to build the last two Ariane 5 and the decommissioning of one Ariane 5 launch table,
has further restricted flexibility and cadence.
Arianespace has to say sorry, not Eutelsat.

I find it dismaying that using an American carrier, SpaceX, is something to be apologized for, but launching on a Russian rocket was always considered to be just fine.

I'm not trying to make an argument from hindsight.  Imagine what you (and by you I don't mean Lenny) felt about Russia before the special military operation?  And judge things from that perspective.

If it's so important to have an independent European launch capability, and I do think that's a desirable thing, why was it okay to cheat and have the Russians do it?

Because Europe was fine with "OPERATING" the rocket, without actually producing it.
Soyuz was a compromise and a good alert for the situation that would have come later in the 2010's.


And then, even when reality like SpaceX came up, and demonstrated that reusability is indeed a thing and an advantage for the company, ESA and Arianespace kept saying that was not a "threat" for them.


I will just leave that here...

Since we are here in the Eutelsat 10B thread, there was no choice for Eutelsat. Either Arianespace can launch it now, or they need an alternative.
https://forum.nasaspaceflight.com/index.php?topic=52361.msg2337981#msg2337981

Likely using this licence

So this is what an expendable F9 FCC permit looks like now (it's been so long).  One of several expendable launches coming up.

1708-EX-ST-2022

SpaceX Mission 1802 from LC-40 at CCAFS or LC-39A at KSC, and the experimental recovery operation following the Falcon 9 launch...
The first stage booster is expendable...
North  27  54  50   West  71  48  9 Boat
NET mid-November
More particularly, NET November 15

I'm assuming the NET 2022 Nov 15 date for this mission was set based on FCC App 1708-ES-ST-2022's OSD, but couldn't that be for Intelsat Galaxy 31/32, instead of Eutelsat 10B?  Currently there is only one expendable launch license, and two expendable missions.

After leaving Fos-sur-Mer in France on October 12, the MV Colibri has reached the Cape Canaveral anchorage area. This vessel is reportedly carrying the Eutelsat 10B communications satellite for a NET November launch date on a @SpaceX Falcon 9. Maybe 1049-11 to be expended?

Looking like NET Nov 13-17 unless it's slipping into Dec. Alternatively, with ViaSat-3 slipping into 2023 and probably liable to slip further into Jan, there's a chance that 39A could be made ready for a F9 fairing launch in late Nov after CRS-26.

Storage. It's not even inside the HIF, it's just parked outside, like they do with a bunch of other boosters when there's no space to store them and they're ready to fly. SLC-40 was occupied by B1067-7 and its second stage for Hotbird. I imagine they already have B1051 on hand there for Galaxy and B1049 was being stored at 39A to then be transported to pad 40 once Hotbird launches. Same thing for B1073, it may well be for Hakuto-R, or maybe it's just for CRS-26, it's not easy to tell since they use 39A as interim storage most of the time.

I received this NGA notice.  It doesn't fit the time reported by NextSpaceflight however it is in line with Ben Cooper: "The next SpaceX Falcon 9 rocket will launch the Eutelsat 10B communication satellite from pad 40 on November 20 around 10 p.m. EST."

Also, the NGA notice for a launch today (November 16) is still active.  This is a totally new notice, not a cancel-and-replace.

Not for sure, but it's been sitting around for over a year, so I'd assume they'd want to do a SF.

Wider launch window > using performance that could otherwise be dedicated to reducing the delta-v needed to reach GEO from the transfer orbit.

They are already using an expendable 1st stage.

They are already using an expendable 1st stage.

So why is the performance loss acceptable on the other GTO missions that have longer windows?

The next SpaceX Falcon 9 rocket will launch the Eutelsat 10B communication satellite from pad 40 on November 21 at 9:52-10:02 p.m. EST.
Only a 10-minute launch window. Isn't that unusual for a GTO launch?
Wider launch window > using performance that could otherwise be dedicated to reducing the delta-v needed to reach GEO from the transfer orbit.

Falcon 9 uses subcooled propellants.  I think that might be the main reason they want short launch windows.  The spacecraft people would probably be happy with their usual 1-2 hour window duration.

For GTO launches, they try to hit a specific point in space. The optimal launch time to reach that point is always the middle of the launch window. However, they are able to extend that launch window by using the margin the launch vehicle has to steer into the optimal trajectory (ULA calls it RAAN steering). That takes a little bit of performance. In the case of Eutelsat 10B, which already is an expendable launch due to performance requirements, that margin is very small which only allows for a 10 minute launch window.

My opinion is it’s a way higher energy orbit.

Maybe apogee might be between 80,000 and 90,000 kilometers and the inclination close to 21 degrees.
SECO confirmed. Nominal orbit insertion.

Online vaporcobra

Also worth noting that Eutelsat was clearly uncomfortable about VHTS and Eutelsat 10B launch delays ~9 months ago. For an all-electric geosat, a supersynch launch could potentially cut weeks off of orbit-raising, weeks that could instead be spent generating revenue.

Quote
Konnect VHTS and Eutelsat 10B satellite delays have “a mechanical effect on our expectations for subsequent years,” Eutelsat said in its Feb. 17 financial report.

https://spacenews.com/eutelsat-pushes-back-return-to-growth-forecast-amid-satellite-delays/

And IIRC, pretty sure Musk or another SpaceX executive has stated that old Block 5 boosters are more high-touch, so fewer qualms about expending them. Several possible explanations, though ultimately I'm pretty sure it just boils down to a service SpaceX is happy to provide as long as the customer is willing to pay extra, and as long as the booster fleet is large enough to survive a culling.

…the deployment of the satellite into a super synchronous transfer orbit will shorten the time needed for it to reach its final operational geostationary orbit by about 10 days.

Really?
Eutelsat paid an undisclosed extra fee to maximize the GTO apogee, which seems to have resulted in expending the booster, to gain 10 days?
Can someone provide a more understandable interpretation of what was written?

Can one of our fantastic launch analysts calculate the maximum apogee at that payload mass with and without recovering the first stage, and then calculate the velocity deficit to GEO for both?

How does the difference compare to ten days of orbit adjustments?

(My guess would be the increase in on orbit lifetime die to the propellant savings.)

Guessing both 15 years lifetime and 100M$ cost and assuming they make 100 times more profit then deprecation it still doesn't make sense.

But they might have either
- contractual obligations
- or a bottleneck, which affects all customers.
That might make the calculation profitable.

The satellite is also supplying data communication for air and sea. That are well paying industries.

Here's a rough guess.  We know 5.5 tonnes is very close to what a recoverable F9 can put into a GTO with GEO apogee.  So about GEO-1800.

We know from the last expendable launch that an expendable F9 can add about 400 m/s to the total delta-V.  So how can that extra performance be used?  If it was all used to raise the apogee it would reach 87,000 km or so, reducing the delta V to GEO to about 1550 m/s.   But the apogee is not that high, so presumably they use the rest for inclination reduction, giving about a 22 degree x 60,000 km transfer orbit.   That's about GEO-1570 (slightly less efficient) but there are reasons a satellite operator might want to avoid a super-high apogee.

This is consistent with the 10-day estimate.  It's about 10% less delta V, so if an electric satellite normally takes 100 days to raise and circularize, a 10% savings would be 10 days.

Also, GEO stationkeeping costs about 50 m/s per year.   So it's 4-5 years added life.

Also GEO-1550/1570 is closer to what Arianespace was going to provide from Kourou, which was I assume the expectation when this satellite was designed.

I don't think this is right.  The first stage cutoff was about 400 m/s more than usual.  If you add this with no inclination change, you get an apogee of 87000 km or so.   But it's only 60000 km so the rest was used to reduce inclination.  By my figuring it should result in about only 21-22 degrees left to remove, and about 1570 m/s to GEO.

Farwell B1049! The oldest booster in the fleet flew for a final time to deliver the Eutelsat-10B satellite to supersyncronous orbit. The weather cleared in time for Falcon to push through the clouds.

B1049 on its last flight now becomes the first Falcon 9 booster to fly in 5 different calendar years. It flew once in 2018, twice in 2019, four times in 2020, three times in 2021, and one last time again in 2022.

Farewell, indeed!

It's amazing how accurate you are, not the first time you predicted the orbit using math before the TLE is published.

It's not surprising that math works but it's still amazing to see.

SpaceX now currently has 16 active Falcon 9 boosters:

• B1052-7
• B1053-2
• B1058-14
• B1060-14
• B1061-10
• B1062-10
• B1063-8
• B1064-1
• B1065-1
• B1067-7
• B1069-3
• B1071-5
• B1073-4
• B1076-0
• B1077-1
• B1078-0

In November, we lost three boosters (B1066, B1051 & B1049).

But at the same time, we got some brand new ones that joined the fleet!

Looked like there was a Mars photobomb on the telescopic tracking at about T+2:08?

Here is a comparison of the webcast telemetry from the Galaxy 31-32 and Eutelsat 10B missions, both of which expended the booster on the way to super-synchronous transfer orbits. The payload masses were about 6,600 and 5,500kg respectively.

Differences in the launch to LEO were that Eutelsat spent a couple of seconds longer in the throttle bucket, inserted 3km higher at 168km, and some 80m/s faster (7,907m/s in the orbital frame of reference), for a higher apogee.

From the vis-visa equation, and assuming that altitude at injection to LEO is at perigee, the coast orbits were:
G31-32 165 x 200km
E-10B  168 x 480km

At insertion to GTO, assuming a starting orbital inclination of 28.5°, then the total ΔV required for a combined injection and plane change is:

G31-32 10,509m/s - 7,827m/s = 2,682m/s plus 4.3° plane change at 198km = 80m/s. √2,682² + 80² = 2,683m/s.
E-10B  10,465m/s - 7,907m/s = 2,558m/s plus 5.72° plane change at 261km = 104m/s. √2,558² + 104² = 2,560m/s.

So, the ~1,100kg payload difference corresponded to a ΔV difference of ~123m/s.

So, the ~1,100kg payload difference corresponded to a ΔV difference of ~123m/s.
I get different numbers but the same general conclusion. Here's how I try this computation (spreadsheet):

From the webcast, we get the altitude at SECO, and the altitude at GTO injection.  I assume the SECO altitude is the perigee.  The injection happens 1/4 of the way around the orbit, so it's half way to apogee, which is 1/2 way around the orbit.  This is not precisely linear, but as the orbits are so close to circular it's close.  So the apogee is about twice the delta of injection.  For example, for Eutelsat10, SECO is at 164 km, GTO injection at 293 km, so I guess an apogee of 422 km.

Next, for any orbit, given the perigee and apogee you can find the semimajor axis a = (perigee + apogee)/2 + Rearth, where Rearth is the Earth's radius.  From this you can find the speed at any radius r from v = sqrt(mu*(2/r - 1/a)).  So find the speed at the injection height.

Now do the same for the GTO orbit using the apogee and perigee from the TLEs.  Find the velocity at perigee.  If there is no plane change, the difference between these number is the delta-V required.

But in these two cases there is a plane change.  This needs to be computed as a vector sum, and depends quite strongly on the original velocity coming in.  Referring to the diagram below, the cross component is VFinal*sin(theta), and the along-existing-trajectory component is Vfinal*cos(theta)-Voriginal.  These are then combined using sqrt of sum of squares.

Anyway, after all this thrashing, it appears Eutelsat10 used about 144 m/s more for GTO injection than Galaxy31.  This is surprisingly low, as the next section below (using the rocket equation dV = Vexhaust*ln(Mstart/Mfinal) ) indicates the second stage alone should gain 293 m/s just from reducing the payload mass from 6.6 to 5.5 tonnes.  On top of that, Eutelsat10 also got about 34 m/s more out of the first stage.  From this, it appears Eutelsat 10 could have been delivered into an even better orbit. I have no idea why this is not the case.

I don't think this is right.  The first stage cutoff was about 400 m/s more than usual.  If you add this with no inclination change, you get an apogee of 87000 km or so.   But it's only 60000 km so the rest was used to reduce inclination.  By my figuring it should result in about only 21-22 degrees left to remove, and about 1570 m/s to GEO.

As it turns out, my program gave a good estimate of 58,090.6 km vs 60,000 km expected, despite entering an incorrect inclination of 27°. I get 60,117.6 km with the correct inclination and 1579.0 m/s to GEO.

Enter initial perigee height (km): 312
Enter SpaceX speed (km/h): 35840
Enter initial orbit inclination (deg): 22.84

Estimated inertial speed = 10405.2 m/s
Estimated apogee height = 60117.6 km

Enter required inclination change (deg): 22.84
Enter final orbit height (km): -1
Geosynchronous altitude = 35786.0 km

Burn at 60117.6 km: theta1 = 21.62 deg, dv1 = 1244.9 m/s
Burn at 35786.0 km: theta2 =  1.22 deg, dv2 =  334.0 m/s
dv = 1579.0 m/s

Alongside:
I have looked at pictures, videos of Eutelsat 10B and after that also of Konnect VHTS and Hotbird 13F (I think 13G is the same).
In my opinion, they all still use Hall Effect Thruster SPT-140D from OKB Fakel.
I had assumed these would be replaced by Safran's PPS®5000 Hall Effect Thruster.
The two are very similar, the performance is about the same.
But the PPS®5000 has a square faceplate, which I don't see on any of these satellites.
The SPT-140D doesn't have that.

Might these four satellites have used the last four OKB Fakel units in stock at Thales Alenia Space and Airbus Defence and Space, respectively?

Well, the matter remains a mystery. Safran writes the Hotbirds have PPS®5000.

EUMETCast Europe Prime Satellite will be migrated from Eutelsat-10A to Eutelsat-10B in July 2023.
Published on

27 April 2023

Eutelsat-10A (E10A) satellite, located at 10˚ East, currently used to provide the EUMETCast Europe service, is nearing the end of its operational life. Therefore, a new satellite, Eutelsat-10B (E10B), was launched in November 2022, as a replacement to E10A.
...
The transponder migration is scheduled to take place between 18 and 20 July 2023, with exact date to be announced in due course.

Eutelsat-10B is still at test position 1.6° E.
While on Eutelsat-10A seems to have given up the north/south correction since mid April.
The inclination of Eutelsat-10A is now 0.22 deg and increasing.
