F9 Super-Synchronous performance with a 5,330 kg satellite

 

 

Falcon 9 delivered apogee: 40,648 km

 

F9 Full Thrust is an over-achiever.

 

Circularization to GEO now even easier than planned, SES is bloody ecstatic. 

 

Elsewhere; paranoia setting in over F9's expendable performance and what this means for Falcon Heavy.

People moaning that it didn't hit the barge landing. The above is what they should be looking at instead. Brilliant news.

Oh yeah, SES has got to be pretty happy with those results. And the fact that SpaceX tried to recover and very nearly pulled it off says volumes.

 

Darn well right paranoia setting in -- on whose part? ULA's? Just imagine if SpaceX is doing a launch to GEO and not going for a recover ... would we then be talking 6,500 kg or even 7,000? Or more?

are they looking at recovering the side boosters and losing the centre for the first few, before going to recover all 3?

 

on the FH? I don't think we know how they're going to do the first few recoveries. Assuming It's all 3 first stages at once :)

yea I've seen that animation as a best case. Was just wondering if they would be trying to pull that off first time considering the extra distance the centre core will have to travel.

As far as we know FH #1 will try to recover all 3 cores. SpaceX is being cagey about the payload, but we can assume that if it's on the light side they'll go for RTLS, and if heavier they'll go for ASDS downrange. 

 

Of course "light" for Falcon Heavy could be a 20+ tonne mass simulator to LEO, and "heavier" could be a refitted used Dragon launched around the Moon on a free return trajectory. Or something we have no clue of.

CRS-11 and CRS-12 are next year, SHERPA in May and Thiacom-8 in June, this year. This will all change soon enough, but I hope FHFT holds, they need the "income generator" up and launching. NSF probably has a better handle on this.

 

Don't shoot the messenger.....:D

ABS/EutelSat will be a dual Boeing 702SP ion  propulsion commsat launch. They'll go into a Super-Synchronous orbit, probably over 65-70,000 km.

No, those are just shiney aluminum stands to keep the model up. If you look closely you will see the individual engine bells on the model just above it. You can also see the individual engine bell shadows  :)

 

Look here for full size and you can see it better: https://pbs.twimg.com/media/CdCwacDWEAAW99u.jpg:orig

 

I also wonder if SpaceX would ever go for such a setup btw, it kinda kills their whole engine out principle.

Do we know if they have enough margin for some GTO missions to do RTLS or is it strictly LEO RTLS and GTO ASDS landing? For example could SpaceX pull of a RTLS with a light GTO satellite?

    • Microsoft confirms Windows 11 26H2, urges IT admins to prepare for release

      By Usama Jawad96 · Posted

      Microsoft confirms Windows 11 26H2, urges IT admins to prepare for release by Usama Jawad Windows 11 typically follows an annual update cycle, but Microsoft recently broke that tradition a bit by releasing a "26H1" version in the first half of this year as a "scoped" build for select new silicon PCs only. This version was not available for customers using 24H2 and 25H2 builds, as Microsoft is busy preparing version 26H2 for them, confirmed officially for the first time. In a Windows IT Pro blog, Microsoft has urged IT admins to prepare for the upcoming release of Windows 11 version 26H2. The company has confirmed that this will be a small enablement package (eKB) that will simply light up certain disabled features that are already present in the operating system's code base. This means that the "refined" Windows update and deployment experience will be simpler and quicker, with minimal disruptions, as the feature update will simply toggle a few flags rather than performing a complete replacement. Microsoft has explained that this is all possible because the standard Windows 11 releases share the same servicing branch and hence, the same source code. However, this also means that Windows 11 26H1 users won't be able to upgrade to 26H2 as that is a different branch, but this is something we have known for a while now. Similar to previous annual feature updates, Windows 11 26H2 will offer the following support cycles: 24 months of support for Home, Pro, Pro EDU, and Pro for Workstations editions 36 months of support for Enterprise, Education, IoT Enterprise, and Enterprise Multi-session editions Microsoft has not confirmed a concrete release date for Windows 11 26H2, but noted that it is "coming soon". If we go by the ongoing release cadence, we can expect it to begin rolling out in early October 2026. As such, IT admins have been encouraged to begin validating Windows Insider releases in the Experimental Channel, plan rollout rings, and strategize the utilization of their existing deployment tools.
    • Windows 11 gets new audio improvements in the latest builds

      By TarasBuria · Posted

      Windows 11 gets new audio improvements in the latest builds by Taras Buria Today's Experimental builds (26H1 and Future Platforms, formerly Canary) pack several audio-related improvements. If your device is enrolled in the Experimental Channel (26H1), you can download build 28120.2315, while those in the Future Platforms version have build 29613.1000 to try. Here is what is new in build 29613.1000: [Audio] Following up on our previous improvements, we’re making some more adjustments to Settings > System > Sounds based on your feedback. Namely, we’ve updated the “All sound devices” page so: You now have the ability to change default devices from this page. Each of the devices displayed on this page now has a little volume meter next to it to show if there is audio actively playing. We’ve adjusted the page design slightly so now you can filter whether you’re viewing input or output devices. We’ve added toggles so you can choose if you want to hide or show disabled, disconnected, and unplugged devices on this page. We’ve also updated the input and output audio properties page for devices in Settings to now include jack information for those that need it. And here is the changelog for build 28120.2315: This update includes a small number of minor bug fixes and improvements. [Accessibility] This update improves caption style responsiveness by redrawing captions immediately for caption style changes. If no current caption is visible, a sample caption string is displayed. [Audio] This update improves the reliability of the inbox HD Audio driver. You can find the official release notes for build 28120.2315 here and for build 29613.1000 here.

      I agree with what I think you are saying, just not in the way you are saying it. Like any tool, the amount it represents your work is perorational to the effort you put into it. It is similar to why 2nd grade math students learning to add and subtract are not allowed to use calculators, but a high-school calculous student is. For the 2nd grader, that tool would completely replace the work they are doing, for the calculous student the same tool allows them to work far more effectively while in no way replacing their effort or knowable. If you spend 30 seconds writing a prompt, then the image that comes out is no more "yours" than if you found the same image with a Google Image search. However, many of these generative tools also support highly iterative processes that allow back and forth, and merging generated images with photos or human created images. I am sure you would agree that a human spending hours of time working on a project, even if AI was involved in the process, still reflects that human's work.
    • Windows 11 version 26H2 is now available for testing in the latest preview build

      By TarasBuria · Posted

      Windows 11 version 26H2 is now available for testing in the latest preview build by Taras Buria Friday Windows 11 preview builds are here. Insiders in the Experimental (formerly Dev) and Beta Channel can download builds 26300.8697 and 26220.8690. There are no new features, but Microsoft is officially moving the Experimental Channel to version 26H2. In addition, Microsoft is improving the copy dialog in File Explorer, the Start menu reliability, and fixing virtualization issues. Here is the changelog: [General] With today’s build, Windows Insiders in the Experimental channel will see the versioning updated under Settings > System > About (and winver) to version 26H2. For more information, see the Windows Insiders blog. [File Explorer] We’ve improved the visual consistency and reliability of the Copy dialog in Dark mode, including its launch experience and the expanded progress view. [Start menu] - Also available in Beta Improved reliability of Start menu reflecting newly installed or removed apps without requiring sign-out or restart. [Taskbar] Fixed an issue for Insiders using the new smaller taskbar option, where the system tray might get cut off or pushed off screen. [Settings] - Also available in Beta Improved reliability of Settings > Apps > Startup. [Virtualization] - Also available in Beta This update addresses an issue that could result in bugchecks citing HYPERVISOR_ERROR (0x20001) and KMODE_EXCEPTION_NOT_HANDLED (0x1E) errors after installing the latest flights on some devices during system restarts, virtual machine operations, or while running some gaming applications. You can find the official changelog for the Experimental build here and for the Beta build here.
    • We now know when and how the Universe may truly end

      By sphbecker · Posted

      I've always preferred this possibility. There is something that feels good about the idea that all matter in the universe will eventually come back together and maybe even result in another big bang. The idea that the universe would fizzle out over the eons and forever drift apart is a little depressing. I realize it is not logical to let a basic human desire for life to have a grand everlasting meaning change the way I feel about a scientific theory, but I am human, so that is how I feel :-).
