Sorry to hear you won't be there remixedcat :(

Back to SpaceX - the below imagery shows my artist impression of the coming Falcon 9 v1.1, based on the latest info from SpaceX and information posted by insiders. There is at least a 50/50 chance that the engine layout will evolve from a 3x3 grid to a design with 8 Merlin 1D engines in an octagon and a slightly different Merlin 1D in the center, it being more vacuum optimized and with slightly larger exhaust nozzle to match. The speculation is that its this engine that would be used later on to land the first stage for re-use.

There is also a video highlighting the development of SpaceX's PICA-X Mars-optimized heat shield.

and just when I had FRAPS record the stream!!!

mabye I can try again to make it down there... mom is gonna flip out.... at least her work schedule is clearer and my sis is doing better....

c'mon..... let may 22 work out.... for my dad.... even if I wont go down there please....

WTH Doc?! they could have launched just fine from what i'm reading! what's this about overly conservative settings? don't be so conservative maybe? i don't know, it's not a huge delay so maybe worth it, and maybe it will give remixed more time to get down there for the launch!

as for the comment remixed shared with us, that is uncalled for. of course it's wrong that SpaceX reps gave this person the rather rude slip, but still, wishing for their failure is wishing for the failure of humanity. that's just wrong.

If F9 were only to be a cargo launcher the pressure tolerances could be set wider and the insurance companies would bear the risk for the cargo & vehicle replacement, but it isn't.

They are seeking a sweet spot where it's as safe as possible for CREW launches. The insurance companies cannot replace crew members. The cost of that is an occaisional pad abort. Gemini had them, as did the Shuttle. Part of the package for 'human rating' a launcher.

Even of this is an engine and not a sensor issue it'll only take a couple of days to fix as there is another Falcon 9 at KSC in their off-pad prep facility. They'll just pull the #5 engine from it and install it in this Falcon 9.

guess in the grander scheme of things this delay is alright, as you say, you can't replace people and it's better to play it safer. tho over caution is a sufefire way to destroy exploration...easy for me to say sitting here typing this, but it's true. i sit here typing this because for two million years there have been people willing to take the risk. or maybe i'm just waxing lyrical now.

Want me to list how many NASA rockets from Mercury to the shuttle, and cargo EELV's, have had pad aborts? Just gof this in my email -

During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine.? We are now in the process of replacing the failed valve.? Those repairs should be complete tonight.? We will continue to review data on Sunday.? If things look good, we will be ready to attempt to launch on Tuesday, May 22nd at 3:44 AM Eastern.

A subsequent tweet revealed it was a turbopump fuel valve, which could have caused a catastrophic failure. Sounds like their hypersensitive flight computer and sensor array wins again.

NOT a fuel valve but one for nitrogen gas.

Grab the popcorn, the party's back on!!

SpaceX spokeswoman Kirstin Grantham said a valve on a nitrogen gas line used to purge the Merlin engine before ignition remained stuck open.

Tests performed Sunday appeared to show the new valve working properly and no evidence of similar problems on the eight surrounding engines.

?Things are looking good,? Grantham said Sunday after the repair work was complete.

The countdown is expected to pick up after 8 p.m. today, with loading of liquid oxygen and rocket-grade kerosene propellant starting around midnight.

my daddy's up there!!!!!!!!!!!!!!!!!

OMG OMG OMG OMG YESSSS IT WORKED OMG!!!

MY DAD'S DREAM FINALLY COMING TRUE!!

I'm in tears right now and this is hitting me so many ways spirtually...

I am SO HAPPY for your dad, you and your family!! He got one helluva ride - that was as close to a perfect launch as they come, and being a night launch it lit up much of eastern Florida.

And just think:. L. Gordon "Gordo" Cooper (Mercury astronaut) and James Doohan (Scotty from Star Trek TOS) were there with him.

    • Microsoft had to shut down 70+ GitHub repos after getting hacked, brings back some by Aditya Tiwari The self-replicating malware campaign known as Miasma took the open-source world by storm. It was reported that almost 73 Microsoft GitHub repositories were infected by the worm and had to be temporarily shut down to determine how attackers compromised projects and stuffed password-stealing malware in the code. These GitHub repos span across different organizations, including Microsoft Azure, Azure-Samples, Microsoft, and MicrosoftDocs. The malware enabled attackers to steal passwords and credentials when compromised tools were opened in popular AI coding apps, including Claude Code, Gemini CLI, VS Code, and Cursor. The security firm Cloudsmith, malware analysis site OpenSourceMalware, and 404 Media were among the first to report the hack. For background, Miasma is a variant of the Mini Shai-Hulud worm, open-sourced by the threat group TeamPCP. It started its journey by compromising a Red Hat employee's GitHub account to attack the @redhat-cloud-services npm namespace. Earlier this month, Microsoft Threat Intelligence reported that the Miasma attackers published 32 malicious packages across more than 90 versions under the @redhat-cloud-services npm scope to steal cloud credentials. The worm didn't take long to start attacking source repos directly rather than package registries. It is known to skip the npm registry entirely for several targets and plant malicious code straight into public repos like "icflorescu/mantine-datatable." The delivery approach was designed to weaponize AI coding tools. Miasma's malicious payload embedded into projects can trigger automatic code execution when the infected repo is opened in an AI coding tool or IDE. The list of affected projects includes "durabletask", a Python package compromised by TeamPCP a month earlier to deliver an information stealer designed for Linux systems. That said, Microsoft has begun restoring some repos affected by the malware campaign, The Hacker News reports. A company spokesperson stated the following: Microsoft will continue to investigate the attack. It has notified a small number of customers who may have removed their content from the affected repos. The company will reach out to customers again through established support channels "if anything further is identified that requires customer action."
    • Why is Opera doing this notification at all? They have their own extension store. They don't have to obey anything dictated by Google. Others like Brave and Vivaldi that rely on Chrome's extension store, not so much. Firefox is entirely separate as well with its own extensions store. I honestly don't understand why entire world is just insisting on Chrome. Like, why? It's a stupid fat browser with barely any functionality. But sure, it's installed on everything by default. I don't understand how people even use web that's filled with tracking garbage and ads all over the place.
    • Just for anyone reading, AdGuard (the free, standalone MV3 extension) is quite good now, a direct competitor to uBlock Origin Lite and much more built-out than it.
