Space Norway contracts w/ @Inmarsat to launch 2 @northropgrumman-built triple-band satellites to HEO orbit on a @SpaceX Falcon 9 in 2022; @usairforce to provide EHF payload; Inmarsat will use Ka-band & Space Norway X-band for Arctic coverage.

their website:

Space Norway will cooperate with the satellite operator Inmarsat and the Norwegian Ministry of Defence to offer mobile broadband coverage to civilian and military users in the Arctic. Two satellites will be built by Northrop Grumman and are scheduled to be launched by SpaceX in late 2022. The ground station will be established in North Norway and ensure Norwegian control of this critically important capability.

“This will be a milestone for people in the Arctic who have very limited or no broadband access in the region” says Jostein Rønneberg, Space Norway ́s CEO.“We are building a robust communications capability in an area strategically important to Norway and our partners. This will be vital for surveillance, fishery control and rescue operations in the vast sea area that is under Norwegian control, and will significantly improve our ability to operate in the High North”.

Space Norway, a limited liability company owned by the Norwegian government, has established a new subsidiary company, Space Norway HEOSAT AS, to manage the program and operate the two satellites together with Kongsberg Satellites Services in Tromsø, Norway. The program is fully financed with customer agreements in place for the service life of the satellites.

“After a multi-year dedicated effort, we are both proud and happy to have closed customer agreements with Inmarsat and with the Norwegian and US militaries”, saysthe Program Director Kjell-Ove Skare. “This is an exciting collaborative effort, which ensures a cost effective solution for all parties. Now we are eager to start the real work of building the satellites and the ground stations. We look forward to providingthe world’s first and only mobile broadband service in the Artic region; somethingwhich has long been an important objective for the Norwegian authorities.”

Both satellites will be launched in late 2022 on a SpaceX Falcon 9 rocket into a Highly Elliptical Orbit (HEO), which will provide full coverage from 65 degrees North,

which in practical terms is the area North of the Arctic Circle. Each of the two satellites will carry multiple payloads, and the system is scheduled to be operational for at least 15 years with users able to switch between current geostationary satellites and the HEO satellites. Each satellite will have a mass of 2000 kg and provide 6 kWatt power through their sun arrays.

So I have some questions about this Space Norway launch.  I don't have a subscription to PBdeS's web site so maybe someone who can read it might get more information:

This launch is using Inmarsat's old contract with SpaceX?  The tweet said Space Norway got the launch through Inmarsat.

63 degrees is in that tweener region between Cape Canaveral and Vandenberg.  Which site is the more likely location for the launch?

[Barley]

63 degrees is in that tweener region between Cape Canaveral and Vandenberg.  Which site is the more likely location for the launch?

I believe these will be in 90 degree inclination orbits.  Essentially hovering over the north pole at apogee to cover the entire arctic north of ~63 degrees.  So either Vandenberg or south from Cape Canaveral if that option becomes available.

Isn't that a classical Molniya orbit? Wow, I think this is the first commercial Molniya orbit comsat that is not from Russia!

For NRO Molniya orbit payload both the Cape and Vandenberg have been used, although Vandenberg seems to have been used more in recent years (NRO L-35/42).

[Northrop Grumman] Arctic Satellite Broadband Mission Satellite System demonstrates Northrop Grumman’s integrated approach to mission success

Dulles, Va. – July 3, 2019 – Northrop Grumman Corporation (NYSE: NOC) has been awarded a contract by Space Norway to deliver its Arctic Satellite Broadband Mission (ASBM) system. Northrop Grumman will design, manufacture and integrate two satellites in addition to providing critical ground infrastructure.

The ASBM satellites will carry multiple hosted payloads including an X-Band payload for the Norwegian Ministry of Defense and a Ka-Band payload for Inmarsat. Northrop Grumman announced last year that it will also provide two Extremely High Frequency eXtended Data Rate (EHF XDR) payloads for the Enhanced Polar System-Recapitalization (EPS-R) to the U.S. Air Force for integration on the spacecraft. The systems are designed to improve secure and continuous communications in the North Polar Region. Additionally, Northrop Grumman was selected to provide critical ground infrastructure for EPS-R.

“This contract award marks our first mission with Space Norway and we appreciate the confidence they have in our capabilities to deliver high quality communication satellites,” said Frank DeMauro, sector vice president and general manager, space systems, Northrop Grumman. “By using our flight proven GeoStar platform coupled with our end-to-end payload integration capabilities, we are eager to demonstrate our ability to provide innovative solutions that regularly exceed our customer’s mission needs.”

ASBM’s satellite system will be designed, built and tested at Northrop Grumman’s state-of-the-art satellite manufacturing facility in Dulles. The satellites will be based on the company’s proven GEOStar platform which has been integrated on more than 40 spacecraft. ASBM is scheduled for a dual launch in late 2022.

Space Norway was established in 2014 as a limited liability, governmentally owned company.

Northrop Grumman is a leading global security company providing innovative systems, products and solutions in autonomous systems, cyber, C4ISR, space, strike, and logistics and modernization to customers worldwide.

Isn't that a classical Molniya orbit? Wow, I think this is the first commercial Molniya orbit comsat that is not from Russia!

This is not a Molniya orbit.

The orbits are related in that each is highly eccentric.  In each orbits the satellite remains fairly stationary near apogee for most of the orbit, and multiple satellites are needed for continuous coverage.

However a Molniya orbit has an inclination of 63 degrees and serves a circle centered on a point 63 degrees north touching the pole on one edge and perhaps 45N on the opposite side.  it does not cover the entire arctic.  In contrast a polar orbit would serve the area of the arctic circle centered on 90 degrees north.

Also because the service area from a Moliniya is not centered on the pole the parameters of the orbit must be chosen so the orbit is Geo-synchronous and the apogee returns to the same spot.  So a Moliniya orbit is fairly specific.  On the other hand any high eccentricity polar orbit can serve the arctic because of rotational symmetry around the pole, geo-synchronous is not required.

I believe your description is incorrect.
A Molniya orbit is a12 hr orbit at the 63 and a fraction degree inclination where the rate of rotation of the line of apsides goes to zero. That way the apogee, which is set at the northernmost point, stays there, rather than rotating away.
But they are only at 63 N for a moment, and then go to 63 South, once per orbit.
If a satellite is at any higher (or lower) inclination, including 90 degrees, then it’s apogee will roll around the orbit. That won’t serve the purpose of remaining high in the sky for extended fractions of a day.
These orbits are not “geosynchronous”. They move across the sky and must be actively tracked.
But one of a pair it trio is always above the horizon and they’re a lot closer than GEO.

[smoliarm]

First, I agree with Comga; Barley's description of Molniya orbit is different from what I remember from Orbital Mechanics (which I passed with "A", but some 20+ years ago).

Second, about the orbit itself:
Space Norway says in their press release it will be - Highly Elliptical Orbit with 43000 km Apogee and 8000 km Perigee. Which does not fit Molniya's semi-major axis.
Also, SpaceNews in this article
https://spacenews.com/northrop-grumman-to-build-two-triple-payload-satellites-for-space-norway-spacex-to-launch/
says the orbit is UNIQUE.
Finally, FCC filing says the inclination will be 63.4°.
So, if everything above is correct, it is going to be a "Molniya-like orbit" - with high eccentricity and same inclination, BUT with different orbital period.
If (again) the apogee and perigee numbers are correct, the period will be 941.6 min, or approx 0.66 of sidereal day.
Which is remarkably close to 2/3 (0.666...)
Satellite in Molniya orbit appears above northern hemisphere twice per day, first around "N" latitude and second around "N+180" latitude (and this is why the same sat in Molniya orbit CAN in fact serve ALL northern regions - but not at the same time).
Satellite in this ASBM-Molniya-like orbit will appear above northern hemisphere three times per two days - in points spaced by 120° by latitude.

Third, about launch site:
63.4° inclination can be reached directly from VAFB. From Cape there is an option to launch ASBM satellites into "transfer orbit", something like 400 km x 43000 km @ 57.5° inclination. In this case satellites have make apogee burn for perigee raising AND gaining remaining 6° to inclination. At this height - 43000 km - it should not take a lot of delta-V. Atleast in 2004 Quasar-15 (launched by Atlas-IIAS from Cape) did the same trick.
Another option for launch from Cape is a "dog-leg", for which Falcon 9 will probably have enough performance since the total payload is about 4000 kg.

Edit - corrected typo.

Te orbit is called Tundra Orbit, a sibling of Molnyia but geosynchronous, it goes over a single point rather than two.

[Comga]

Te orbit is called Tundra Orbit, a sibling of Molnyia but geosynchronous, it goes over a single point rather than two.

That doesn't seem right
It is related to the Molniya orbit, with that special inclination.
But as smoliarm said, it appears (hovers briefly) "over" three different spots around the north pole.
It is NOT geosynchronous is the classical sense that it doe not remain synchronized with the earth's motion at all times.
It's ground track loops around the world.
That ground track does repeat with a period of three days.
(If having an integer number of days between repeat cycles made it "geosynchronous", then ALL orbits would be geosynchronous, just with number much larger than one.)

(Ha, smoliarm!  I think I passed Orbital Mechanics 401 some 30+ years ago, but can't remember my grade.)

(Ha, smoliarm!  I think I passed Orbital Mechanics 401 some 30+ years ago, but can't remember my grade.)

Go and check Tundra orbits and Japan's QZSS. The reason it is 2/3rd of a day is to be able to put 3 satellites to give continuous coverage at very high inclinations. The racetrack wrt fixed-Earth reference frame is fixed, it looks like an elongated 8. So I do consider it geosynchronous, just not at 1:1. I very specifically said geosynchronous and not geostationary.
Molnyia can be made to have two or three peaks in it's Earth-fixed racetrack. Northern Hemisphere users obviously prefer the 2 peaks. But I've always speculated about a 3 peak Molnyia for the Southern Hemisphere so Argentina, Chile, Australia, NZ and South Africa could have communications close to their antarctic bases. Regrettably you'd need 12 birds for that.

[smoliarm]

Ok, once again, I've passed exam in Orbital Mechanics a LONG time ago.
Therefore it's possible I forgot something important.
However, here is what I seem to remember, in somewhat random order:
1.
Tundra orbits BELONG to the type called "geosynchronous"
2.
All Geosynchronous orbits have orbital period STRICTLY EQUAL to Earth's sidereal period (which is 24 hrs minus ~ 4 min, IMSMR). Therefore, All Geosynchronous orbits have STRICTLY defined semi-major axis, which one can calculate from 3d Kepler's Law.
3.
Tundra orbits include those geosynchronous orbits with inclination of ~ 63°

Now, on this particular orbit for Space Norway satellites:
If we assume the apogee (43000 km) and perigee (8000 km) reported by company ARE correct -
- then this orbit DOES NOT belong to Tundra family, nor it belongs to Molniya orbits.

And one more thing on *orbit names* - (again, IIRC) -
Let's denote satellite period as *Ts* and planet rotation period as *Tp*.
Now, if the ratio Tp/Ts can be represented by some (small) INTEGERS - then such orbit will be called *Phase-Locked*
In other words:
GEO = Phase-Locked with Tp/Ts of 1:1
Molniya = Phase-Locked with Tp/Ts of 2:1
"Space Norway orbit" = Phase-Locked with Tp/Ts of 3:2

Launch of Arctic Satellite Broadband Mission (ASBM) satellites delayed from late 2022 to early 2023:

USSF’s EPS-R Program on Schedule for Historic Polar Mission [dated Oct. 29] (bolds mine)

LOS ANGELES AIR FORCE BASE, Calif. -- A unique partnership with Norway and the U.S. Space Force’s Space Systems Command will extend satellite communications for U.S. polar forces and save taxpayers millions of dollars.
 
SSC’s Enhanced Polar Systems-Recapitalization (EPS-R) program successfully completed the ready-to-ship review at the end of September for the first of two payloads to begin the integration process onto Space Norway’s space vehicles.
 
EPS-R is an Extremely High Frequency (EHF) MILSATCOM system designed to extend EPS (legacy) services into the early/mid-2030s. Its mission serves to provide 24/7 protected satellite communications for U.S. polar forces operating in the Arctic region.
 
<snip>
 
Using a host space vehicle like Space Norway means it is imperative the SSC team meets its scheduled deadlines to coordinate with Space Norway, Philichi said. The second payload is expected to hit its ready-to-ship milestone just before Thanksgiving.

<snip>

Hosting the EPS-R payload on the Norwegian Artic Satellite Broadband Mission (ASBM) is projected to save the USSF more than $900 million dollars, and deliver Satellite Communication capability to the polar region three years faster than a traditional satellite acquisition program.
 
“Norway is a key U.S. ally in the polar region, and because of technology mitigation, the technical risk is low for integrating a National Security Space payload on their Arctic Satellite Broadband Mission (ASBM),” Leach noted.
 
By January 2022, EPS-R plans to have both of its Northrop Grumman-built payloads complete. The program is on track for a dual launch with Space Norway scheduled for early 2023.

Final Arctic Protected Satellite Communications Payload Delivered for Integration on International Host Vehicle

EL SEGUNDO, Calif. – Space Systems Command’s Military Communication and Positioning, Navigation and Timing Directorate recently delivered the second of two Enhanced Polar System Recapitalization (EPS-R) payloads to begin integration on Space Norway’s Arctic Satellite Broadband Mission host space vehicles.

The EPS-R payloads, built by Northrop Grumman at its Space Park campus in Redondo Beach, California, supports a first-of-its-kind program - a U.S. Government payload being hosted on a commercially procured international host satellite.

“This delivery marked a major milestone towards the launch of the EPS-R satellite program to provide vital protected satellite communications to the warfighter in the increasingly important arctic region,” said 2nd Lt. Clayton Lieberman, EPS-R Payload Integration & Test lead.

Both payloads are undergoing integration onto their respective space vehicles and are scheduled for dual launch in late 2023. Once operational, they will provide 24/7 secure coverage to polar users for both strategic and tactical communications.

While the EPS-R satellites and ground system will be operated by the U.S. Space Force, the primary users of this capability are the U.S. Navy’s surface and subsurface fleets, and Coast Guard operating in the North Polar Region.  EPS-R will provide users with protected broadband communication into the 2030s.

SSC is the USSF field command responsible for rapidly identifying, prototyping and fielding resilient space capabilities for joint warfighters. SSC delivers sustainable joint space warfighting capabilities to defend the nation and its allies while disrupting adversaries in the contested space domain. SSC mission areas include launch acquisition and operations; space domain awareness; positioning, navigation and timing; missile warning; satellite communication; and cross-mission ground, command and control, and data.

SAT-MPL-20220311-00029

the technical narrative was updated in the meantime.

[gongora]

Request to FCC for extension:

Space Norway has paid all obligated costs to its satellite and ground station suppliers and has paid 95 percent of the total launch costs owed to SpaceX. Space Norway anticipates that the satellites will reach 100 percent completion by mid-November 2023.

Space Norway also believes that its request for a 12-month extension of its Milestone Deadline is justified. Specifically, Space Norway believes 12 months will not only ensure adequate time for completing the two satellites, performance of the launch services, and conducting in-orbit testing of the satellites, but also provide additional time to account for any unforeseen serious delay that may occur during the remaining testing. The ASBM System satellites are presently undergoing initial integrated system testing in preparation for thermal vacuum testing. Recent testing delays have further impacted the ASBM System’s schedule—based on current projections, Space Norway will not be able to launch the satellites until, at the earliest, November 2023, and a launch in early 2024 is more likely. The two satellites will be launched together on one Falcon 9 launch vehicle and SpaceX has confirmed assignment of the October 1, 2023 to January 31, 2024 launch period for deployment of the ASBM System satellites. Northrop Grumman estimates that from launch, it will take approximately 64 days to place the satellites in the correct orbits and achieve operational status.

[EimajOzear]

Is it fair to assume the booster will be expended for this launch?

Edit:
This suggests the launch mass is actually 7,200kg: https://spacenorway.no/en/heosat/

More info on satellite bus here: https://www.northropgrumman.com/wp-content/uploads/DS-44a-GEOStar-3.pdf

With ASDS recovery, parking orbit could be something like 300km x 12,000km or 1,000km x 10,000km.
If expending, parking orbit could be closer to 1,000km x 25,000km.

Either way, based on the ~1,500kg propellant mass in both satellites, it's clear they have enough chemical prop to permit such orbit changes.

The Norwegian parliament directed Space Norway to acquire all Norwegian owned space assets so this is a step in the process. Each satellite network will be acquired as separate subsidiaries initially.

International Partnership’s Arctic Satellites Arrives at Launch Site After
Integration and Testing
Summary: Arctic Satellite Broadband Mission’s EPS-R payloads and their host space vehicles
arrived at Vandenberg SFB launch site to begin final integration prior to summer launch
VANDENBERG SFB, Calif. - Space Systems Command’s (SSC) two Enhanced Polar System-
Recapitalization (EPS-R) payloads, now integrated with the Space Norway host vehicles -- the
Arctic Satellite Broadband Mission (ASBM) -- arrived at Vandenberg Space Force Base, California
in mid-June. The two satellites will now begin final integration with the launch vehicle in
preparation for dual launch as soon as July.
The combined payloads and host vehicles received approval for shipment to the launch site
after successfully completing the integration and test effort in which technicians electronically
and mechanically mated the payloads to the host vehicles. After mating, the combined system
underwent rigorous testing to ensure compatibility and readiness to endure the unforgiving
environment of polar orbit.
Space Norway’s ASBM hosts the United States Space Force’s (USSF) EPS-R payloads as well as
Norwegian military X-band payloads and ViaSat Ka-band payloads. The payloads, fabricated by
Northrop Grumman, are integrated onto two commercial GEOSTAR-3 satellites. The partnership
between Space Norway and the USSF marks the first time an operational DoD payload will be
hosted on an international space vehicle.
USAF Maj Michael Walsh, Space System Command’s EPS-R Branch Chief, explains, “There is a
critical need for polar satellite communications, and that need has grown exponentially in the
last few decades. The partnership with Space Norway for this mission is the first step at
securing the Arctic region and paving the way for future international partnerships here at SSC
and across the Space Force.”
The unique environment of the Arctic region and the collaboration with Norway make this
partnership a true pathfinder for future USSF programs. EPS-R will also be crucial to two
National Security Strategy priorities - ensuring security in the polar region and building
international cooperation with allies. EPS-R and the partnership with Norway are major steps
towards meeting fundamental priorities to maintain the security of the United States.
“For decades, there has been an unmet need for broadband communications in the Arctic, and
we are now establishing a strategically important capacity for everyone operating there,” said
Space Norway’s ASBM program director, Kjell-Ove Orderud Skare. “Our focus in this mission is
the value it creates for civil users such as ships and aircraft, and governmental users such as
rescue services and the Coast Guard, as well as national and allied forces. We are all looking
forward to providing the first dedicated broadband services to users in the real Arctic.”
On April 19, Northrop Grumman’s EPS-R Control and Planning Segment (CAPS) received
Operational Acceptance. CAPS is the follow-on ground system for EPS and will be used for the
control and planning of both the EPS and EPS-R satellites. This milestone meets one of the
Service Acquisition Executive for Space Systems and Program’s acquisition tenets of delivering
ground before space.
The partnership between the USSF and Space Norway is a significant milestone for the
Department of Defense as the integrated deterrence and cooperative alliance provides
enduring strategic advantages against our adversaries. Moreover, the use of commercial
development for the space vehicles and launch services will result in this vital capability being
delivered faster and cheaper than traditional DoD acquisition processes.
About Space Systems Command (SSC)
Space Systems Command is the U.S. Space Force’s field command responsible for acquiring,
developing, and delivering resilient capabilities to protect our nation’s strategic advantage in,
from, and to space. SSC manages a $15.6 billion space acquisition budget for the Department of
Defense and works in partnership with joint forces, industry, government agencies, academic
and allied organizations to outpace emerging threats. Our actions today are making the world a
better space for tomorrow.

Okay, here's a weird one.

<snip>

Note that the dates and start times match the original Space Debris notice except that it doesn't include July 22. The end times are all two minutes earlier than the end times for location B.

I sincerely doubt this launch goes tomorrow, July 16.

However, I suggest that we (spaceflight enthusiasts) watch for SpaceX activity at all three Falcon 9 launch complexes.

I know that SLC-4E is not line-of-sight from publicly accessible land, so that would mean sea, air, or space reconnaissance.

Within the law, of course.

The mishap must be investigated, but I suspect that a launch will proceed as soon as possible after return to flight authorization.

Edit July 16: Starlink 9-4 is now the next scheduled Vandenberg Falcon 9 launch, NET July 22 UTC.

[zubenelgenubi]

Starlink 9-4:

NextSpaceflight; updated July 25:
Launch 28 July 07:24 UTC

So, it's not a surprise:

NextSpaceflight; updated July 26:

Arctic Satellite Broadband Mission (ASBM)
Launch Time
NET August 2024

But, launch could be in earliest August, because OCISLY turnaround may not be needed.

Re-post; expendable first stage?

<snip>
I'd expect this to delay at least a day or two, this would be a pad turnaround record for SLC-4E with Starlink Group 9-3 scheduled at a similar time on the 11th. Current SLC-4E turnaround record is 4.5 days.

Does this give any hint to if its expendable?

Perhaps.  Assuming that the schedule is indeed as listed above, SpaceX means to launch ~3 days after the previous launch.

The payload mass is too heavy for a first stage landing at LZ-1.

This is apparently too short a time for OCISLY to turnaround via the Port of Long Beach, implying an expended launch.  B1061.22?

Looking further ahead, if this launch goes ASAP, SpaceX may launch another Starlink Group 9 before Transporter-11.  Or, it could launch the third Starshield cluster for the NRO.

Transporter-11:
