> “One of the best use cases for in-space servicing, assembly and manufacturing is antennas,” Badesha said. “The satellite to cellular broadband market needs big antennas. Imagine if you could start making antennas in space, unfurlable antennas at the cost of fixed antennas.”

> On June 20, Orbital Composites announced a memorandum of understanding with Virtus Solis Technologies focused on a megawatt-scale commercial space-based solar power station. Under the agreement, Michigan-based Virtus will design core technologies. Orbital Composites will develop the necessary manufacturing processes and offer manufacturing-as-a-service to Virtus.

for a given launch vehicle it depends on thrust/weight ratio and aerodynamics

>staying afloat below orbital velocity has a cost/unit time
>there's a max speed through which you can travel at a given altitude (air density) without disintegrating
>more speed=more drag and more heat
>if manned, max acceleration is ~4g

Things get more complicated with multiple stages.

Without any atmosphere you'd shoot the rocket horizontally like a bullet as fast as possible
With a single homogenous layer of atmosphere it depends on how you calculate drag losses but you get the idea. Then you can integrate over infinitesimal layers of atmosphere.

it's just a tall cylinder to visualize the height. they can fill most of the fairing on SLS but starship has an as-yet unknown payload door for non-starlink payloads. If you look at the cylinders you can see shading on them, the white and light grey are the same size between both and the dark grey on SLS is extra height over starship's current capacity. Starship also has header tanks in the nose to worry about, and the upper fin structural reinforcement as well. Expendable rockets just have bigger fairings to go with their bigger price tags.

>>15515071
>Commercial companies need to develop capabilities and programs to ensure they remain relevant in this new marketplace.

>And governments need to partner with companies to develop laws and standards that encourage space development while ensuring this new marketplace remains competitive.

>If governments and the commercial sector do not act now, SpaceX’s head start will become an insurmountable lead, allowing SpaceX to dominate the space sector for decades to come

>>15515071
> In early December 2022, SpaceX introduced its Starshield concept, a satellite program offering satellite-based secure communications and optional sensing payloads to government customers. However, despite its subdued announcement, Starshield is, in fact, a Trojan horse that will enable SpaceX to further dominate the space domain and dictate policy to businesses and national governments alike. With the new Starshield program, SpaceX is on the verge of transforming its dominance into a monopoly. Governments and businesses must act now to counter any attempts to monopolize the space industry in order to preserve consumer choice and to ensure national policy remains in the hands of elected governments.

> SpaceX’s current dominance of the commercial space market is starkly illustrated by the fact that OneWeb, the nearest competitor to SpaceX’s Starlink, was forced to select SpaceX as its launch provider. SpaceX, a private company, can already control its competitors’ access to space and force its policies on national governments. There is simply no other company that can compete with SpaceX’s cost and responsiveness.

this makes it sound like they had no choice
no, that is not correct
they could have launched with competitors too, it would just cost more and take longer, and would cost even more on the competitors if spacex didn't exist

> SpaceX’s Starshield has the potential to remove many of these barriers to “app” development.'

many other satellite bus manufacturers and companies exist besides spacex

>>15515005
anyone get her name? socials?

>>15515071
> Governments should prioritize enabling competition by setting policies that encourage — or force —SpaceX to develop open, license-free protocols and universal non-proprietary device interfaces. That way, potential competitors could build alternatives to the Starshield bus that can still interface with the new burgeoning satellite component industry.

what the fuck?
this dude didn't mention the numerous other starlink competitors in the works or the many other companies providing satellite buses, or even the many launchers that will try to compete
very alarmist article, SpaceX hasn't done anything anti-competitive/monopolistic as far as I know

yes, and that would still be the case if SpaceX didn't exist
the argument is retarded, they aren't "forced" to launch with SpaceX
in the alternate case they wouldn't be able to launch at all and would have probably gone bankrupt and cancelled

> Our joint Starfish Space & Launcher Orbiter SN3 mission statement.

https://www.launcherspace.com/updates/orbiter-sn3-mission-update

>Orbiter SN3 Mission Update

> Additionally, Orbiter’s batteries were in a power negative state due to non-optimal sun-pointing and there was risk of not being able to contact the vehicle on later ground station passes. Within minutes, the Launcher mission operations team reacted to the initial data provided and decided to deploy the payloads earlier than scheduled, rather than risk non-deployment. This decision was also made in light of the fact that Orbiter has a separate backup customer spacecraft separation system on board, but given the small chance of improving the state of the vehicle, the operations team decided to command deployment of the spacecraft early.

So something went wrong with SN3 attitude control system, making it spin in a way that made it get too little power from the solar panels and thus draining the battery
they decided to yeet the payloads early due to this and Starfish got yeeted spinning around too much, which it couldn't correct with the on board attitude control system resulting in mission failure I guess
there is no mention what happened to the other 2 payloads

People figured that out in the 1940s anon, it's just that making a spaceplane with 1940s tech is a bit HARD. Then we made ICBM and derived most of our rockets from it .

Then came the 70s and post-apollo and NASA actually gave a shot at it, but technical budget and political compromise gave a flawed RLV

Soviets briefly looked at it and concluded they didn't need it because they already produced 60 soyuz a year.

Then it was looked again in the 90s but fixation on SSTO and coms-bust killed any projects before they could fly; thne for the next 15-20 years there was no war (so no need for quick launches capability) and the only semi-profitable commercial launches were heavy GTO sats that were unweildly so nobody bothered, then came SpaceX.

>>15515768
>space communist larp fest where there is no more large scale political/economic/military intrigue and all the races in the federation hold hands together and sing kumbaya
I at least want my science fiction to have some grounding in basic reality

>>15515810
well then so was the shuttle. a payload with a payload in its cargo bay. Add to that all of the production facilities compounded by the various soviet subcontractors reaching into the thousands across the "union" and it was at least as big of a money hole relatively as the shuttle program was to develop

>>15515768
I stay out of sci-fi because its just that, fiction. Show me reality and I will care

>>15515815
The shuttle literally had the sustainer engines on it, Energia flew without Buran.

The intent is completely different, the intent of the shuttle was to make a RLV from its inception.
The intent of Buran is just "how do we get the same orbital capabilities as the americans", nowhere did that intent need a RLV

>>15515815
The Shuttle had the sustainer stage engines attached to the orbiter and the ET was just a droptank. Energia's RD-0120

>>15515823
The Buran was an upgrade in comparison to the Shuttle, if anything. It's tiles suffered less damage during re-entry and it's booster could be used with different payloads other than the Buran.

>>15515830
It was a rather minor upgrade if I'm being honest, There were issues, It lacked multisegmented SRBs sure, but then RD-170 was not very reliable in the 80s, and Energia had 4 of them with a very theoretical engine out capability; its internal insulation means there was no foam risks, but it increased ice falls, which was very scary in the one Buran launches and arguably worse than foam damage.


The main advantage of Buran is that, ironically, it wasn't conceived as a cost-cutting RLV, yes that made it more expensive but that removed the need to move all payloads to it that NASA had to justify it, so Soyuz and Proton could keep flying on the sidelines.

>>15516050
All seem pretty good. Though I hesitate to credit Musk personally since he was probably following his engineers' advice (and ignoring advice from other engineers). That's a skill in and of itself, but without being intimately familiar with the company's inner workings I don't think it's fair to give all the credit to him. SpaceX does an excellent job avoiding tunnel vision and the oldspace mentality of "how do we make this work" which is great for something like the Apollo program but bad for a company.

>>15516092
He's the chief engineer, he makes the final call. Even if you think he's not an engineer, he's still the chief executive which makes the final call. Unless the argument is, Musk has no will of his own, and everything is dictated by his engineers.

>>15516086

>>15516048
Not everyone has shitty eyes from being inside all their lives.

>>15516095
My point is that each of those decisions had a huge amount of legwork and theory behind them in order to be condensed to the point at which Elon actually made the choice. It's not like he woke up one morning and thought Starship should be stainless steel; the idea was probably floating around SpaceX for some time, then someone ran the numbers and presented them to Elon at which point he realized stainless steel made more sense and made the call to switch over. A good company is one where that process happens quickly, even if the CEO just shoots the idea down, and it's that structural and cultural element which is often more important than the headline making decisions.

He's definitely a great CEO, and part of that is his decision making. I'm just skeptical of the notion that his companies' successes come from His divinely inspired vision. People and groups tend to succeed for very mundane reasons, and then generalize those reasons into individual splendor and heroism; you see this a lot historically with generals embellishing battles with post hoc tactics and explanations even when they were utter shitshows won through blind luck.

You can watch a show, enjoy a show and frankly love a show without knowing every insignificant actors/props. Frankly speaking, the character Will Wheaton played was a shitter. Absolute shitter. Particularly, his character from the show reflects his ideological/personal characters. IDK if he was influenced by the character or if his radicalization on the far left made him into a such a shitter, but thats who he is.

https://spacenews.com/ecuador-signs-artemis-accords/

The late 1977 Energia design Was the wackiest, at the time the USSR lacked the means to move the two tanks that made up the core, so they instead had to settle for 4 smaller tanks (2 set of Hydrogen and Oxygen), but it didn’t stop there.

The RD-0120 were supposed to be fed from the lower two tanks, while at the same time the upper two tanks were supposed to refil the lower ones, then once the upper tanks had been emptied, shortly after booster separation, the upper two tanks were supposed to be jettisoned, leaving Only Buran and the bottom part of the core it was attached to.

Because the Buran+Half core stack had a more offset Center of mass than the IRL Buran+Full core stack, the RD-0120 had to be angled, like the space shuttle’s ssme, but on the core stage

what did they do right (if anything)?
they were brave to try new things, perhaps they had rapid innovation, idk

to make it more explicit, the bad thing is that they didn't learn and improve upon the "old" way thing were done, they basically just ignored everything

why didnt india get an astronaut on the iss through russia?

>>15517585
The USCG seems pretty confident the debris the found was from the titan, which I guess is the best case scenario? Death was instantaneous. Which is better than suffocating to death, or having to choose who to kill to bid more time assuming they were stuck or something.
As an aside: I’ve seen videos of people suffering from hypoxia in fighter jet training chambers. I assume this is way different than suffocation from too much CO2 right? With hypoxia everyone seems to laugh and become delusional. But throw CO2 into the mixture and I assume your body starts screaming in pain. Very fucking grim

>>15517757
yes they found the titanium domes and other parts, it 100% imploded early in the dive

>>15517761
At least it was instantaneous! I’d rather die in a submarine implosion than run out of oxygen in a spaceship or something. Ugh imagine your harness breaking during an EVA—that would probably be one of the shittiest ways to die

>>15517743
VGH?

>>15517769
falling into a black hole would be a good mix of “coolest thing ever” and “absolutely shitty death”

That's actually a pretty interesting idea that could work well. SpaceX could consider that as an alternative to chopsticks cause it gives you a larger area to land it, and you can just reposition it after you catch it with the wires to put it back onto the mount really precisely

>>15517919

>>15517919

>>15517920
It's literally stolen from an /sfg/ scribble ideapost btw

>>15517920
>it gives you a larger area to land it
Does it? You have to get it between the gaps in the wires and it's a fairly tight fit since the fins don't extend very far.

>>15517931
The /sfg/ idea was stolen from discord, which in turn was borrowed from reddit. But no one wants to admit that
This fucking general hasn’t had good OC since the early days of the hop campaign. Everything is stolen from twitter or reddit—I’m sorry I am the one that has to break the news

>>15517935
The idea is that the wires can move to any position over the landing area (like a cnc router or something) so they can catch it as long as it's somewhere over the landing area which could be much larger than the valid area where the chopsticks could catch it

not for long. Meat is stripped from the bones in a matter of days, weeks tops. In a few years the bones will be dissolved by the salty ocean water. Reason you never find bones on the titanic but suspiciously arranged clothes and pair of shoes that look like they might have been on somebody a long time ago

This is a dumb question but was the Titanic a household-name incident before James Cameron’s movie? Or did that movie do a lot to launch it into mainstream knowledge

There were half a dozen movies about it before Jimbos. Everyone knew about it
