We have some info on the next Isar Aerospace Spectrum launch. It looks like they have two launch windows: 6 to 19 December 2025 and 13 to 24 January 2026. There was NOTMAR published the first 6-9 Dec window, but it looks like that has since been cancelled.

This thread should be in the "International Space Flight (ESA, Russia, China and others) » Other Launchers (Korean, Brazilian etc.)" board, not in the "Commercial and US Government Launch Vehicles" as it is a German launch vehicle.

[olemars]

It's a commercial launcher. There are dozens of threads that will need to be shifted around if that means US only. I think it's better to contact a site moderator/admin instead of posting about it in each thread, they're meant for actual updates and news.

[TheKutKu]

This thread should be in the "International Space Flight (ESA, Russia, China and others) » Other Launchers (Korean, Brazilian etc.)" board, not in the "Commercial and US Government Launch Vehicles" as it is a German launch vehicle.

No, it should be included in the ESA launcher section, the upgrade of Isar Block 2 is being funded under the Component B of ESA Launcher Challenge program, it is therefore an ESA Launcher now.

"ESA Launcher" is not "Arianespace launcher" either since Vega is going to be commercialised by Avio from 2026 onward.

It's no less of an "ESA Launcher" than Vega-C or Vega-E

I don't understand why new EU launchers are spread all over the place on 3 different subforums; all Indian launchers are in Indian section, all Chinese launchers are in Chinese section, no matter who is developing them, it SHOULD be the same for Europe, if necessary, then rename the ESA Section.

[FreakySquirrel]

Well, that depends on whether being moved from a commercial launcher to an ESA one qualifies as an upgrade.
Apologies—I clearly lacked the willpower to keep that comment to myself.

But I agree that it's really confusing to find the European launchers.

[olemars]

Want to point out half the threads in the commercial launcher forum are european or asian, but now some are getting moved to the other section because of random comments like this. Someone either needs to do a proper cleanup and redefinition of the various subsections or leave things as they are or things are just going to get even more scattered.

[FreakySquirrel]

Well, now Isar Spectrum flight 2 is in commercial and Isar Spectrum flight 1 is in Other Launchers (Korean, Brazilian etc.)

I agree that at least the launchers in this slide should be in the "ESA Launchers - Ariane/Vega" subforum.

The problem is that many headers in the subforums and sections have been defined over a decade ago and make little sense today (e.g. the confusion between "Missions To The Moon (HSF) - Forum section dedicated on HSF Missions To The Moon (EM-1 etc)." and "Heavy Lift Launch Vehicle (HLV/SLS) - Section for the Heavy Lift Launch Vehicle (HLV) or Space Launch System (SLS). Home of DIRECT's Jupiter, SD HLVs and other HLVs" or "Orion and Exploration Vehicles - News and updates specific to manned exploration vehicles, such as Orion and Lander concepts", which might have made sense in the 2010s but not for quite some time already, especially when "EM-2" is already coming up in a couple of months! ... not to speak of the absurd "Missions To The Near Earth Asteroids (HSF) - Section dedicated to HSF missions to NEAs", whose raison-d'être existed for a shorter time than the years passed since it was cancelled!).

Some forum history: I personally asked PLD Space's threads to be moved to ESA Launchers a few weeks before Miura-1's debut flight. It stayed there for a while until someone decided it wasn't truly "ESA" (strictly speaking, true) and it was a commercial company (again, strictly speaking it's true). The obvious problem is that the "Commercial" section is clearly oriented to US launcher initiatives or payload-centric companies, whereas enterprises from the rest of the world usually have a much stronger link with public financing. I think there's also a kind of unspoken stigma against having one's country end up in the "Other Launchers" section, which I fear is seen as a one-size-fits-all basket of minor (should one even say, underdeveloped?) countries' space programs.

However, one thing is certain: if the current status quo of having every private company's launcher programs under the "Commercial" section as long as it was mainly kickstarted by private funds rather than government directive, regardless of where the funding will end up coming from in the end, then many recent Chinese launchers should also be here - including Zhuque, Hyperbola, Ceres and the like. Of course, the same applies to Russian, Japanese or Indian private launchers, but there are fewer of those. I'm not necessarily advocating for this solution, but otherwise the logic makes no sense and the "Updates on the Commercial space sector." subheader should be amended to "Western Commercial space sector" or something.

[jebbo]

Personally, I think generalising "ESA Launchers - Ariane/Vega" to "European Launchers" is the best solution.

Technically, a slight issue as bits of Russia are in Europe, but hopefully still clear enough.

Also, on the point above about "Commercial," that section is in the "Commercial and US Government Launch Vehicles" supersection, and that title implies US and should probably be reordered to read "US Commercial and Government Launch Vehicles"

I think we can use the holidays to have a good refresh.

If I read this NOTAM correctly, launch isn’t happening within 2025 it seems:

Andøya Space planlegger gjennomføring av aktivitet i Børvågen torsdag 11. og fredag 12. desember Dette medfører at FV7698 kan bli stengt inntil 8 timer i tidsrommet 10.00-22.00 Det vil varsles når veien stenger og åpnes igjen

chatgpt translation:

Andøya Space is planning to carry out activities in Børvågen on Thursday, December 11, and Friday, December 12.
This may result in FV7698 being closed for up to 8 hours between 10:00 and 22:00.
Notifications will be given when the road is closed and when it is open again.

That is directly at the launch site. And it was changed from 10/11th to 11/12th. My guess is, that would be the roll back of the rocket.

Less than nine months after first test flight: Isar Aerospace clears final tests for second Spectrum launch [Dec 22]

Less than nine months after Spectrum’s first test flight, Isar Aerospace has completed stage testing and is preparing for its second launch from the company’s dedicated launch complex at Andøya Space in Norway. Both of the vehicle’s stages passed 30-second integrated static fire tests, validating vehicle readiness for final integration and launch operations.

“We are building more than rockets, we are building the capability for nations to access and sustain space on their own terms,” said Daniel Metzler, CEO and Co‑founder of Isar Aerospace. “Rapid iteration is how you win in this domain. Being back on the pad less than nine months after our first test flight is proof that we can operate at the speed the world now demands.”

If nothing else—and the rocket fails—we’ll probably get some epic videos

Don't Jinx it please.
I think ISAR Spectrum launch serveces are needed. So I'm really keen on it launxhing succesfully.
