Is there much change from SN3? I presume we don’t get much information about that

 

They reused the SN-03 lower skirt, which includes the 6 landing legs.

 

There are also plumbing upgrades, including a revamped pressurization system. Problems with pressurization and a human error killed SN-03. Welding is constantly being improved. Domes are also bring improved.

 

SN-05 has numerous changes, and they're prepping to add the revamped fins and larger landing legs. 

 

Also, wider rings are in the plan...

On to mounting three Raptor engines and a static fire...

 

"SN4 PASSED CRYO PROOF! :D"

 

 

 

I think SN4 is only planned for a single raptor and hopefully a 150m hop test with SN5 going full 3 engines.

Yup. Good odds SN-04  gets longer landing legs and the nose cone. 40/60 it gets fins.

Postponed "a few days."

 

The Cameron County Judge (county/parish executive in most states) signed off on a Route 4 road closure, but the state roads dept. had other plans and pulled rank. 

 

They'll likely do equipment checks, a wet dress rehersal, then fire up the pre-burners and let 'er rip.

I'm so excited that they are already going for reusable vehicles that are not supposed to go back to earth, I suspect this could put us on a quick path toward space only transportation vehicles, which could quickly open a lot of new and exciting possibilities.

Here's to hoping for an orbital construction yard soon 😄

SN-04 STATIC FIRE!!

 

SN-05 is being stacked, SN-06 is right behind her.

 

Single Raptor engine, ~4 seconds. Ramping to the 3 engine center cluster, with 6 engines being the usual compliment (3 each sea level & vacuum optimized)

 

The Super Heavy booster gets 31 sea level engines.

Buckle up kiddies...

 

1 hour after the successful SN-04 static fire with a 25 tonne mass simulator, the FAA issued a 2 year suborbital RLV launch license. This is for any number for Starship missions.

Monday's NOTAM is for up to 26,000 feet.

 

Also; they'll be removing the flare stack, replacing it with a condensation unit so they can trap & liquify vented methane instead of burning it.

Not much left of SN4. Roll up SN5.

    • Apple unveils Siri AI, a "reimagined" version of SIri

      By sagum · Posted

      Right, Google... because that's who this is going to. Google, the company who's entire business model is geared around ad revenue and your personal data.
    • Bluesky COO warns social media regulations could destroy competition from small startups

      That is the natural course for regulations. First to protect the consumer. Then to protect the business/industry from upstart competition. There are countless examples across history.
    • LibreOffice developer takes a dig at Euro-Office in new open letter

      By Ccl Ncc · Posted

      I have never been a huge fan of libre, it feels really good but exactly when you need an advance feature for data wrangling it falls short every time or has bugs. I am all for euro office if they can deliver a good and usable alternative to MS office with backing of govt function.
    • Dell, HP PCs ran into endless reboot, BitLocker recovery loops but Windows 11 isn't to blame

      By grunger106 · Posted

      Go on, I'll bite. How does windows (nice comment on an 'article' which doesn't actually involve it ) lock users out of their data then? Been using it since 3.1 back in 92 and not once have I been locked out of my data? Perhaps you mean Bitlocker? In which case the average user (who doesn't mess about) will have been forced to use a MSA, and in which case the recovery key would have been saved to said account..... If the user did happen to bodge around and not use an MSA then Bitlocker wouldn't have become live (as it cannot without a safe place to store the key) I want to point out Bitlocker and MSA are not connected and you can of course force it on without a safe place to store the key, but you do that with your eyes open. So your standard consumer who knows no better sets up an MSA, gets bitlocker and a recovery key stored off box, with a route to reset their password. All of this notwithstanding the fact, if your data is important, you back it up, no ifs, no buts, no-ones responsibility other than your own. Important data lives in at least two locations, one of which is offline and recovery is tested, otherwise that data wasn't really that important. Disks, fail, laptops get lost, phones end up down the toilet, tablets get stolen, if your only copy of data is on a single device you're doing it wrong.

      Clearly that feature isn't for us. It's for the ad spam marketers so they can more directly target us about going to places we might want to go again...but without understanding context clues. Like for the flight someone took for a friend's funeral. We want to be reminded of that every time we open an app, a browser, or email, right? Right, Siri?
