Uttamattamakin got a reaction from wONKEyeYEs in Success SUCCESS for Starship, now land the thing and make HLS ASAP. (and other Space News)
SUCCESS SUCCESS. I would call this what a Successful test at this stage looks like. It got to space and most of the way back. What Artemis needs is for Starship to do TWO things. They need to demonstrate FULLY SUCCESSFUL REENTRY and landing for both a tanker version AND a human rated version. Starship HLS is not meant to ever come back to Earth but landing on Earth will not be harder to land on that the moon since Starship needs a flat place to land. On Earth we can make that happen.
What I am hoping starship HLS will turn out to be is not a Starship as we've seen it but an item made for space... made to go up and stay up and transfer people to and from the Moons surface I doubt we'll be seeing a Flash Gordon pulp sci fi looking rocket on the Moon. The streamlined shape and casing just aren't required in space.
Even Thunderf00t had to give it to him.

The pez door didn't seem to properly close [I'm wondering if that's the reason they decided to skip the engine relight...or maybe they decided against it after what happened to the booster].
Nice to see the boostback for the booster work correctly (I think you could see the starship in a few of the booster camera views as things happened). It's unfortunate they didn't have a softer water landing, I'm wondering if there was some type of issue with their software design for the return (after all they never really would have been able to properly test it). The reason I'm guessing this is that you have the one gimble engine light, but you had 2 other non gimble engines light [right around the time they experienced the instability]. So I'm wondering if either they had initial issues lighting and what we witnessed was the software trying to compensate by firing 2 other engines or if maybe the return burn had instructed the wrong engines to light.
Booster seems like they might be able to fix it though, if it was an issue about too little fuel remaining they could change up the flight a bit. I'm thinking that maybe they were intending to do the relight a bit earlier in the decent because the grid fins I don't think were meant to handle keeping it stable at those speeds in full atmosphere.
One thing, iirc this boosters grid fins actually went back to close to the original design [not that it would make any difference]
That plasma was so cool to watch. With how the camera began overheating or whatever it was was interesting to see as well (with the feed going on). I'm wondering if they didn't have quite as much control as they hoped for with the flaps (it seemed to not be keeping the ship in correct orientation).
Although if the Pez doors didn't close, I wonder if that would have caused the issue. From my understanding they have to form a partial seal in order to partially repressurize the cargo bay to maintain structural stability. If it failed to close it might have met it's fait by folding itself during re-entry. [All speculations at this time].
Lots of what looked like foam as well when it started entry, so I'm wondering what sections those came from.
Overall a good flight, if the propellant transfer was successful they actually will have passed the NASA milestone (which means it's worth $53 million).
So here are my official guesses from watching it once, booster failed to preserve enough fuel for engine relights/didn't plan for the forces that quickly where they will do a second decent burn in the future to reduce the forces [or some way to reduce the velocity before hitting cloud height]...I think they might have underestimated the speed it would return.
Upper stage, I think the door not closing correctly might end up being one potential cause since it could snap during re-entry; but I'm on the fence I think they had maneuverability issues which might have caused the issue.

So I'm a little bit behind the live stream but Phase 1 went literally perfectly. Launch was seemingly flawless. Hot staging went perfect. Max Q had no visible issues (The Pez Bay door didn't crumple in half).
The Booster made the boost back burn, everything looked good for the first part. The second burn did seem to have some issues right before Ocean splash down. I'm not sure what exactly what supposed to happen, but according to the data from the stream, it hit the ocean at something like 1100 km/h, and the relight didn't seem to happen properly. This might have been a telemetry issue or it might have been an actual issue. Either way, this is still a huge success, and none of these issues will affect Artemis.
The Starship itself made orbit, and I'm waiting to see how the re-entry goes. Skipping ahead in the live stream - they're waiting for signal with the Starship. There might be some issue with the re-light of the raptors, as it seems like they skipped a burn in orbit. But now the Starship is maneuvering for de-orbit.
Damn - the camera feed of the de-orbit is insane. You can see the plasma form in HD. The maneuver doesn't look like it's going properly but I'm going to wait until there's a debrief before I comment on what I'm seeing. It's crazy how the signal is holding strong throughout the re-entry. Looks like they've stabilized. So far so good. Video keeps cutting out but that's expected.
Starship was officially lost during re-entry but that was also expected.

IFT-3 is likely to be Thursday if the FAA grants the license on time; the explosives are already installed and full WDR has been completed (they greatly decreased the propellant load times)
https://www.spacex.com/launches/mission/?missionId=starship-flight-3
The sub-orbital trajectory has changed in order to accommodate the tests they wish to conduct in space. It seems like this time they have a large confidence that they will achieve sub-orbital numbers; as the amount that they have put into the Starship upper stage is quite a bit more than has been seen in the past [along with the change in trajectory]
The biggest thing with the trajectory change is likely due to relighting an engine in space. While it's not mentioned, the trajectory gives a larger window in case things go wrong on the relight [like if it fails it will come down over the ocean still]. One speculation as well is that the fuel transfer they do could also show that an engine can be relight from the transferred fuel...but maybe not.
One thing to note, the payload doors are not welded shut this time, which could be a potential for excitement on lift-off/stage separation/max-q. The reason being that it's speculated the doors were welded shut on IFT-2 because they were working out the structural supports needed to not crush the starship. So if there is to be a failure pre-engine cut off I wouldn't be surprised if that ends up being a cause....so yea my guess it would be t+52 seconds where the payload doors will show if they have been sufficiently supported.
It should be noted though, there is a high confidence of it reaching sub-orbital velocity...but there is a really good chance at it breaking apart during re-entry [assuming everything goes right up to that point]. The reason being that the heat-shield tiles iirc are on an earlier mounting mechanism on this version still...but if it survives it (or even if it doesn't) SpaceX will hopefully be able to start gathering data on how hot the stainless steel on the belly gets to [and at what point it fails with how many tiles missing].
It's expected, but as far as I can tell not confirmed that they will just do a bellyflop into the ocean [as opposed to attempting a soft-landing followed by having to blow it up to sink it]. It's most likely though as they don't mention trying to relight the engines for landing.

NOTE:
What I plan to do with this thread is just collected any news that might be interesting regarding Space related technology in this thread. New news will be marked as a solution. To see the new news see the solution.
Summary
Space X's Starship had a launch today which did clear the launch pad. The pad did better this time by a lot. The first stage did explode "Rapid unplanned disassembly" according to Space x. Second stage was clear and away when it did and seemed to be rocketing along ... until it too appears to have had a rapid unplanned disassembly. On the bright side parts of it may have reached orbit.
Quotes
According to Space X
My thoughts
This is much better than before but still far from good enough. If NASA had SLS blow up twice they'd be done for. Both of those systems have taken a toll on their launch structures. Super heavy appears to have not even knocked over the cameras and the water deluge appears to have been enough without the flame trench. Closer examination could change that but at least it wasn't the mass destruction that occurred before. A real improvement.
All engines stayed lit on superheavy.
Superheavy blew up after hot staging of Starship. Star ship was clear and away, it appeared to be clear and away by a lot when super heavy did explode.
The above images show the explosion of Starship itself. In real time Tim Dodd was not smiling like that when it blew up he was looking concerned and confused by the Space X people cheering. He is due to ride on one of these around the Moon in one of the first missions, a private mission called "Dear Moon".
Congratulations to Space X for doing a little better. Bear in mind, for comparison. No Saturn V ever blew up during testing. No Space shuttle did during testing, sadly two did fail while manned. In modern times SLS has not blown up once. Falcon Heavy has not blown up once. The numbers are small but for this number of launches this number of failures is not good.

Uttamattamakin reacted to manikyath in We Downgraded all our PCs to Prove You Don’t Need a New One
well no.. most large businesses just replace when systems are 'n' years old (usually 4 years), and they end up in the hands of people who flip them for a quick buck after tossing out the disks.
this kind of office computer is in fairly constant supply each hardware generation, if you know where to look.

Uttamattamakin reacted to TannerMcCoolman in We Downgraded all our PCs to Prove You Don’t Need a New One
We know you probably WANT a new computer, but do you really NEED one? Odds are good that, for most people, a brand new rig is simply not necessary. To prove it, we swapped our writers' sick gaming rigs full of modern hardware like the latest CPUs and raytracing graphics cards, for something a tad more...quaint. Specifically, 6th gen machines from Dell and HP. Will they be able to protect their jobs and meet their deadlines, or will the lag of old hardware stop them in their tracks?

Get outta here with you tax fraud.
They wanted fun funny mean like
"Linus beardless looks like he went through 4 years of combat on the Ukrainian front"

Uttamattamakin reacted to matt0725 in Linus Reads Really Mean Comments
my favorite part of watching these (and reading them when i come across them naturally) is the wide ranging reasons for hatred. In the same video sometimes, youll get linus attacked for being a shill(seems to be untrue, but sure, you can think that), another cast member attacked for their phyiscal appearance(commenter is a dick), and a third commenter who is enraged about a safety protocol being violated( maybe correct but a weird thing to rage on the internet for). its just such a melting pot

Uttamattamakin reacted to Elijah Horner in Linus Reads Really Mean Comments
It sounds good in theory, but this type of video sadly doesnt have the same "Stakes" or "Content". When people see a title like "Staff reads positive comments" most of an audience will go "yeah ok just going to compliment looks or channel or ...." But when people see its mean comments, they go "I wonder what is being said" or "what could be so mean"
I hope that makes sense, and yeah the thread of ideas is def the place to post that stuff, we go through it every week 😉 and have def used some ideas

Uttamattamakin got a reaction from sub68 in Linus Reads Really Mean Comments
This video is why I come here. This very day I have to set up a meeting with the dean to discuss student concerns which likely include contradictory diametrically opposed things. That class is going too slow they aren't learning enough. I just read from the slides others gave me. They aren't really learning anything. AT THE SAME TIME class is going too fast. I'm teaching them too much that is not in the book. (going just a little beyond the book to a slightly more advanced place to show that I don't just read the book). That its all too advanced and they aren't keeping up. (Class contains people who just barely passed Calc 1 along with people who are in Differential Equations). Along with aspects of the class I don't control (Homework system that does not sync with our LMS) and more senior faculty do. I can go on... I've had my own version of reading mean comments for a while. I was viscerally angry about that and more to the point of wanting to cash my retirement fund out of the market while the cashing is good.
Then this.
This video made a right turn in my day.

except in this case SpaceX is the disruptor *and* the mass producer. that's the very point of the image. the supposed "known values" are dwarved in number by the relatively "inexperienced and small" disruptor.
this graphic would be like tesla v other cars if tesla sold half a billion cybertrucks, and ford sold a douzen... that's not the case.
i dont just disagree that spacex v other rockets is like tesla v other cars.. i'd dare state the opposite.
tesla is a "halo tier" brand of luxury cars, supposedly on par with mercedes, BMW, audi, etc.
in this analogy, spaceX is the cheaper "but not quite cheapest" option.. or to put it in car brands:
- rocketlab is your "kia" - cheap but functional.
- SpaceX is your "volkswagen" level of car.. more than the "cheapskate brand" but still a budget-friendly option.
- launching with a government entity is your halo tier.. you're essentially guaranteed of success, but at a steep cost.
we're entering a world where there's cost tiers of launch providers, because to some entities having 99.9% chance of making it off the pad is enough compared to 99.9999% at 1000x the cost.
on that note.. what's your opinion on rocketlab?

Uttamattamakin reacted to Serin in Apple Vision Pro - A PC Guy’s Perspective
Well, I know Thomas Marrone from the STO dev team contributed, so the chances are some of it is from games. And I know that the Archive has a pretty close relationship with him and STO's assets.
At the same time, they have access to assets from the shows as well, at least to some extent.
For my part, I was working from studio reference and game assets, then modelling my own assets from them. So I think its safe to say it'll have been a mix.
And yeah! It'd be a really good step forward to bring characters into it, but given the way they're doing things here(its not rendering locally, its essentially a NeRF or 3d scan of sorts rendering on their servers then sending video to the device - probably require a biiig rework.

First impression I noticed from the video is the very noticeable marks on Linus's face. This is going to be a thing for people who wear that thing a lot and who are of a more fair complexion. Most will want to cover it up. Some will want to show it off.... others may try to simulate that tan like like yeah I totally have 3500 USD to blow on it. See this tanline.
As for the ending the real issue with Vison pro was stated masterfully. I wont spoil it
If these AR glasses were made by a bigger company, like Samsung. https://us.shop.xreal.com/products/xreal-air-2-ultra and costed 699 that would be your Vison pro killer. 699 is what my new prescription glasses cost. If I wouldn't need to then also shell out for prescription lenses I'd just order those, then upgrade my trusty Note 20 to an S23 to get spatial computing. This way I could see the real world with real light and my real eyes and also have my apps if I need them.
TLDR Great video. Vision pro is hopefully more like a Dev kit for eventually VR/AR glasses for the masses.
