Increased to 118m tall

 

100t useful to LEO, Mars with refuelling

 

Spaceship has grown from 48m to 55m long.

 

Payload volume: 1100 m3

Aft cargo bins (the petals!!), easier unloading. 88 m3

 

Thought: in case of launch abort they could drop the aft cargo to increase the thrust/weight!! 

Upper fin not aerodynamic, just a leg.

Bottom fins are control surfaces and legs.

Tank cylinder built, engine bay and domes soon.

 

Trying for orbital test in 2-3 years.

Big SOB! 

 

May change it's name.

 

May launch from floating platforms.

 

Working towards closed loop CO2/water systems.

 

Would like to see lunar trips.

Re: Boeing saying 1st on Mars will be on Boeing rocket? "Bring it!!"

Engines: BFS engines & nozzles upgradeable. These are SL. Cost: a few aft cargo racks.

2-4 engine out w/landing.

Max G: adjustable in exchange for payload. This mission 2-2.5 G, up to 6 G otherwise (harsh trajectory.)

HOLY CRAP!!

 

The spirit of Douglas Adams gets his 42 

With 42 200 ton/448,000 lbf engines that's 18,816,000 lbf of thrust

 

Maybe a Block 2 or Block 3 returns to a 12m core?

Wireframe of BFS entry, descent and landing (EDL). 10x real-time until terminal approach, then real-time.

 

Bottom line: it comes down like a skydiver at terminal velocity, using the fins and canards like a skydiver does limbs, then rights itself for landing. 

 

There are hints it could have significant crossrange, and burn into LEO from BEO.

 

 

 

I was waiting to post until the dust had settled a bit, but more and more dust keeps getting kicked up hehe ...

 

There are going to be a few progressive iterations of the BFR/BFS architecture. We know of two so far. That's what the current state of Engineering can actually do right now; but there are technologies that need to be flight-proven first on BFR/BFS 1.0 before they get scaled up (and then evolved) for the 12-meter version.

 

I haven't heard of an expansion to 10-meter at the thrust structure, but there shouldn't be anything to prevent doing so. In fact, aerodynamically-speaking it would help more than hurt but I'd like to see the aero sims and the physics modelling they've done. In the grand scheme of things that'd help the booster a tad when doing its' return (more stable, etc.) ... so yeah, good call. The smaller fins can't just be there for show, either.

 

I wonder if they're still going with the "landing cradle" idea? Seems like a lot that can go wrong with that scenario, though ... I don't see any evidence of landing hardware on the booster so I'd think that's still a "yes".

My $0.02: this 9 meter Block 1 BFR is for exploration beyond Dragon 2,  a  USAF Launch Services Round 2 proposal, and a pathfinder for the 12 meter Block (X).

 

Those USAF LS R2 contracts are supposed to be announced very soon, and there have been reports SpaceX would get 2 awards. Getting an award for Falcon Heavy is a given, but one for BFR would be an effing market earthquake.

 

AIUI, the 3 booster "fins" near the thrust structure are guide and gripping planes for the landing cradle.

[Teal Group's Marco] Cáceres, who's studied the aerospace industry for decades, said the new photos highlight a project of epic proportions.

"This is probably the biggest challenge that I've seen since the Saturn V days, in terms of engineering," Cáceres said, referring to NASA's Apollo-era moon rocket. "Nothing I've seen is remotely this size."
>
Revealing these images forces the public  and potential investors  to take Musk seriously, Cáceres said.

If the 2023 moon mission aboard BFR, a project Maezawa calls #dearMoon, is successful, that would send a big message to NASA about SpaceX's capabilities.

"This doesn't look like a stunt,"  Cáceres said. "It   looks like a trial run."

"In a way, he's shoving it in NASA's face and saying, 'You guys are crazy to build this rocket,'" Cáceres said of Musk and SLS, respectively. "Elon Musk is a very charismatic figure and a showman. He understands that, for many years, NASA has been trying to create public excitement about space exploration, and they always try to recreate the excitement around Apollo. But they're not successful."

Musk, on the other hand, may be beating NASA at that goal.


"The thing Musk is building looks like it's out of a science fiction movie. He wants to get the public excited, and that excitement can attract investors," Cáceres said.

And what he announces loudly in high-traffic conferences, his Big F***ing Rocket (BFR ), his Raptor, all that is science fiction, let's say it. And Musk is only concerned about one thing: transportation.
>
I do not believe it too much because Nasa has already invested billions of dollars on a launcher called the Space Launch System, the SLS . And NASA has no interest in shooting itself in the foot by financing the BFR . And SpaceX alone will not be able to finance the BFR and the Raptor ... In the very long term, Elon Musk's approach is bluffing.

1) sci-fi that's being built, and Raptor is spitting very big fire, so scratch the "fi".

 

2) but NASA is interested, and that bluff is about to smack CNES and many other soverign space agencies in the nose.

    • Alien Isolation 2 will bring a new protagonist and setting, watch the reveal trailer here by Pulasthi Ariyasinghe Only a few weeks ago, Sega and Creative Assembly dropped a teaser for a new Alien Isolation. Today at Summer Game Fest, Alien: Isolation 2 was officially announced with a new trailer while also confirming a whole lot of information about the setting of this survival horror project. Check out the reveal trailer above. Leaving behind the Sevastopol space station, the sequel will take players to a remote colony world. With a Xenomorph (or more) on the loose, players will be navigating both the surface of the weather-ravaged planet as well as "the claustrophobic confines of the Weyland-Yutani outpost of Kurosaki Station." Interestingly, Creative Assembly is leaving behind Amanda Ripley, the daughter of Alien's Ellen Ripley, as the protagonist too. While it hasn't confirmed a name yet, players will be taking the role of a new character for this new adventure. The setting is also being described as a new hunting ground for the Alien. This will have players improvising and developing new tools to aid in their survival and escape, all to avoid "cinema’s deadliest killer." "It has been over a decade since we created the original Alien: Isolation and I am so excited to show everyone the first glimpse of the sequel," says Al Hope, Creative Director at Creative Assembly. "Our dedicated Survival team at Creative Assembly has been working hard to create a new, evolved Isolation experience continuing the legacy of the Alien franchise, making the eponymous killer smarter, the environment harsher and the chance of survival slimmer." Promising the same deadly tension from the original from over a decade ago, Alien: Isolation 2 is in development for PC, Xbox Series X|S, Nintendo Switch 2, and PlayStation 5. A release date has not been announced yet.

    • Like the article stated, it's written completely from scratch, unlike the umpteen Chromium clones. It got its start as the browser built-in to the also written-from-scratch SerenityOS.
    • Hello, From looking at the screen shots in your motherboard's manual at https://endownload.colorful.cn/EnDownload/MotherBroard/2022/Intel 600/Manual/Intel 600 Series BIOS English/Intel 600 Series BIOS User Guide.pdf, you go to the ADVANCED option at the top of the BIOS (UEFI) menu, then select SECURITY in the list of options on the left.  From there  you can enable and set the Secure Boot mode.
