Saturday's launch will be the fifth overall for the Falcon Heavy. The burly rocket debuted in February 2018 with a memorable test flight that sent SpaceX founder and CEO Elon Musk's Tesla Roadster into orbit around the sun, with a spacesuit-clad mannequin named Starman in the driver's seat.

The Falcon Heavy launched again in April 2019 and June 2019, sending operational satellites aloft each time. But the rocket didn't lift off again until November of last year, on the USSF- 44 mission for the Space Force. The 40-month gap was due primarily to delays in getting customer payloads ready, according to space industry analysts.

Like USSF-44, USSF-67 is a classified mission. We do know a bit about the coming flight, however.

The main payload is a military communications satellite called Continuous Broadcast Augmenting SATCOM 2, which the Falcon Heavy will send to geostationary orbit, about 22,200 miles (35,700 kilometers) above Earth. Also flying Saturday is a rideshare spacecraft called Long Duration Propulsive ESPA (LDPE)-3A, a payload adapter that can hold up to six small satellites, according to EverydayAstronaut.com (opens in new tab).

LDPE-3A will carry five Space Force payloads on USSF-67. Among them are "two operational prototypes for enhanced situational awareness and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability," Space Force officials said in an emailed statement on Friday (Jan. 13).

The Falcon Heavy consists of three modified SpaceX Falcon 9 first stages, which are strapped together. The central booster is topped with a payload-carrying upper stage.

Falcon Heavy first stages are reusable, like those of the Falcon 9. The two side boosters for USSF-67 will be launching for the second time; they also flew on USSF-44, Space Force officials said. The USSF-67 core booster has not flown before.

If all goes according to plan, the two side boosters will come back to Earth shortly after liftoff on Saturday, making vertical touchdowns at Cape Canaveral Space Force Station, which is next door to KSC. The central booster will not return, instead ditching into the Atlantic Ocean.

USSF-67 is part of a busy weekend for SpaceX. The company also plans to launch 51 of its Starlink internet satellites to low Earth orbit atop a Falcon 9 on Sunday morning. You can watch that mission here at Space.com as well.

WE ARE GOING.

It's just that easy.

>>15123384
>It's just that easy.
SpaceX though that too before learning that it's not that easy in rocketry.

Has anyone leaked the new KSP volumetric clouds mod?

>>15123384
It's not that easy. Falcon Heavy was delayed for like five years and the centre core is not a regular Falcon 9. It's redesigned to carry horizontal loads.

>>15123847
It's just because the ISS is overcomplicated and built with 40 year old ideas. I doubt such a requirement will exist in starship.

>>15123834
Elon dies, F9 because the new soyuz, flying late into the 2080s

>>15123865
Having a modular design that could be assembled into light medium and heavy variants was a great idea. But most of the Angara 1's payloads got eaten by the Soyuz-2v, the Angara 3 was too big a rocket all of the payloads that are flying on the Soyuz-2a/b, and the first two versions never flying is a big part of why the Angara 5 costs three times as much as the Proton it was supposed to be replacing. The worst part is that the Russians can't just get rid of it because its the only rocket they have that's big enough to launch station modules.

>>15123865
they have launched what, 4 in 10 years? Seems like they keep the rocket alive for political reasons, once soyuz is completely phased out It's over for the russian space program.

>>15123869
do you think it will exist in Gateway?

>>15123854
It would have been a great rocket if it actually became operational when it was supposed to be lmao. Would have completely btfo the GTO market at the time.

>>15123782
It's been fun so far, the first two weeks are usually the worst due to the physical tests
We got to shoot blanks already. Some moron in a nearby unit managed to smuggle one blank inside and fired it. The entire unit lost their vacation.
It's good that my autism detail spreads slightly beyond spaceflight; knowing beforehand how to take an RK-62 apart in under 10 seconds makes classes a breeze

>>15123877
Yeah the program started in 1992 (!) and it took until 2014 before flight testing actually began. And it’s only had 5 orbital attempts since then. At this point Soyuz-5 (Irtysh) might become the new work horse for pockocmoc (if it ever gets built) with Angara sidelined to military-only. Although realistically they will probably just keep Soyuz-2 alive for 100 more years

>>15123889
>Some moron in a nearby unit managed to smuggle one blank inside and fired it.
Based. did similar thing in school only it was a sort of firecracker

Why does SpaceX choose to expend a F9 booster over flying FH and reusing all boosters?

>>15123899
Older boosters are more annoying to reuse than new ones due to small design changes

>>15123866
Shuttle was made to drop nukes in a funny way

>>15123899
Theres probably a bit of risk involved with Falcon Heavy. Its been reported that expendable Falcon 9’s are priced at $80+ million.

Im curious about the performance of Falcon Heavy with 2 cores reused to LEO/GTO. We know the fully reusable and fully expended figures only

>>15123899
This sat is going to GEO so I guess they need more power;

>>15123889
THIS IS A NEW AUTISM RECORD

>>15123895
Went shooting with my dad and his friend once and I forgot I had one earmuff off my ear. 58. caliber musket 5 meters away and my ear was still ringing the next day.
Our corporal came in our room to give some orders and he was completely drowned out by a firing line 50 meters away. Can't imagine a 7.62x39 going off next to me indoors, that damage is permanent.

>>15123873
It feels like Russia made the mistake of not retiring all their legacy vehicles in favour of flying Angara. A modular design doesnt seem inherently bad but the Russians botched the execution

brehs when is FH launching

>STS-51B: O-Ring failure, vehicle almost lost
>STS-51C: O-Ring failue, vehicle almost lost
>STS-51D: One tile lossened during ascent, Elevon structure damaged during reentry
>STS-51F: RSLS abort after SSME ignition then Abort to Orbit


Early 1985 was cursed for Shuttle launches, NASA was incompetent to keep trying to achieve a high cadence after it.

Also FH is probably delayed to tomorrow

>>15123894
It's not quite that bad. They knew they needed a rocket that could fly from a non-Baikonour launch pad in 1992, but they didn't settled on the current design until around 2001. Soyuz-5 actually tested its engines last year so that project might be making some progress.

Soyuz-2 is never going to die. The Russian military doesn't actually have much need for heavy lift capacity and the R7 is just too damn cheap for any competitor to dethrone it.

>>15123915
6 months

>>15123913
They made the mistake of not simply keeping the energia family and built up on the development of the reusable zenit boosters.

>>15123920
Why did they stop flying Zenit, anyways? Zenit seems like the perfect solution
>Single core Zenit can bring Soyuz/Progress to ISS
>Triple core Zenit can launch space station modules and stuff
>Five core Zenit can do lunar missions and stuff (is 40 tons to LEO enough for this with 2 launches?)

>>15123926
Zenit is a Ukrainian rocket.

>>15123926
I think Zenits are a ukrainian thing so after the dissolution of the CCCP that kind of went out the window

>>15123926
The production was in Ukraine

>>15123926
It was made in Ukraine along with plenty other Soviet equipment. They briefly operated it with Sea Launch, but nothing more came out of it.

>>15123926
>Why did they stop flying Zenit
Russian invasion of crimea

>>15123926
Rights went to Energomash/Yushmash in Ukraine with the dissolution of the USSR, and Russia and Ukraine might not be too keen to share rocket technology at the moment

Why was Zenit being built in Ukraine a bad thing (at the time in the mid 90’s)? ESA does…fine…using a bunch of countries to build their rockets. I guess im confused why Russia couldn’t just work with Ukraine on Zenit the way ESA does stuff

Will someone ever make a liquid engine more powerful than F-1A? It hasn't flown but produced more thrust than RD-170.
For me, it seems like the era of huge engines is over.

They did succeed in that for over 20 years though, even through the numerous wars in between

>>15123957
It's like cylinder displacement in cars, past a certain point it's easier to add more than to make bigger.

>>15123961
Shit, you're absolutely right, I forgot about it. Everything but that, of course.

>>15123957
You could just have made a post stating that the F-1A is more powerful than the RD-170 than trying to veil with a retarded question lmao

>>15123957
Probably not; It’s not necessarily about the power of a single engine. It’s about optimizing TWR, preferably with something medium sized that can be clustered a la Raptor, BE-4, etc. The RD-170/180 is way cooler than the F-1—the giant size of the Saturn V engines were due to the fact that the air force wanted something super powerful but didn’t know how to do it any other way at the time

>>15123977
There's also the chance that thing's go better because less money is being embezzled. There were more than a few accusations that a lot of the profits from the RD-180 sales were ending up in Rogozin's pockets.

>Returning all three boosters to the launch site rather than landing them on drone ships would yield about 30 t of payload to LEO.
Current Heavy can only do 8t to GTO, current Falcon can do 5.5, both reusable.

>>15123994
Energia was insanely based, that’s why

>>15123999
Is there a definitive list of FH performances depending on reuse mode?

>>15123999
It’s so fascinating. I don’t know enough about rockets to understand why this is, but propellant crossfeed was deemed way too bothersome to attempt. Anyone know more specifics on this?

>>15124002
No, I'm just quoting wikipedia. I'd expect decent sized error bars on all these numbers.

How long will it take for Ukraine's space administration to recover?
iirc Yushmash was hit in the early weeks of the war, and Dnipro gets hit like every day of the week

>>15123990
That's great, thanks energiabro.

>>15124008
I don't expect they ever will. They never really "recovered" from the collapse of the USSR when all of the really vital parts of their spaceflight program ended up in another country. They could build rocket stages but not serious engines, and all of their domestic propulsion know-how was limited to kickstage thrusters like the RD-843. Even if the war ends tomorrow they still have to deal with the fact that all of their best talent fled to the West decades ago and their managers aren't any less corrupt than the ones running Roscosmos.

>>15124003
FH Crossfeed was always supposed (yes, even in the early 2010s) to be specifically for high performances launches, they never needed it since they are developping Starship.
Pumping the fuel from different tanks while the engine is running is hard an never done before, closest thing are jettisoned lateral pumping (Atlas, Shuttle, Ariane 4)

It's possible now. The question is when would it be practical to build one with the resources of a large corporation or a nation state, or maybe when would it be affordable to live in one for people with a median income.

I guess one way to estimate that is to start with some assumptions about the total mass needed, plus the mass of construction equipment and the population required for construction, plus the costs of the infrastructure for that population to live in space and so on.

Why does the fairing have a shiny point?

>>15124229
Japan literally legally couldn't do commercial launches until the 2000s because
1) they were cucked by the US which prevented NASDA from commercial launches as a condition for technology transfer
2) they were cucked by the Tanegashima fishermen trade union which limited launches to narrow windows

So HIIs were never really made with commercialisation in mind, these were relaxed in the 2000s with the foundation of JAXA but 2) still prevented optimal commercial use until 2011 (there were some attempt at commercialisation in the early 2000s but this plus a few failures shut it down). From there they tried but they didn't have the good launcher in a market saturated by Arianespace and then SpaceX, so their first commercial launch was a secondary Korean payload in 2012 and then a primary Canadian payload in 2015.

Let's be real, chief, this tells us, like, "hey, we can get away with redirecting asteroid 420X69-B using a 200kg impactor instead of a 250kg one!"

But if an asteroid was actually on a collision course with Earth, we'd just throw like 5 nukes at its ass.

The Chinamen might also launch a few as well.

>On 19 July 2014, Roscosmos launched the Foton-M4 satellite containing, among other animals and plants, a group of five geckos. The five geckos, four females and one male, were used as a part of the Gecko-F4 research program aimed at measuring the effects of weightlessness on the lizards' ability to procreate and develop in the harsh environment. However, soon after the spacecraft exited the atmosphere, mission control lost contact with the vessel which led to an attempt to reestablish communication that was only achieved later in the mission. When the satellite returned to Earth after its planned two-month mission had been cut short to 44 days, the space agency researchers reported that all the geckos had perished during the flight.
>The exact cause that led to the deaths of the geckos was declared unknown by the scientific team in charge of the project. Reports from the Institute of Medical and Biological Problems in Russia have indicated that the lizards had been dead for at least a week prior to their return to Earth. A number of those connected to the mission have theorized that a failure in the vessel's heating system may have caused the cold blooded reptiles to freeze to death.

You could find plenty by looking at Russian space science efforts after the collapse of the USSR. All of their major scientific missions were either resuscitation of soviet leftovers or were technical assistance for international projects were the actual project came from another country. Or were about microgravity gecko fucking, apparently.

>>15124385
No. The data tells us "we don't need a 1 megaton TNT equivalent impact to redirect this asteroid, 333 kilotons will suffice." The scaling factors are very important to know in these things. You can't "just nuke it" either, since there's generally not enough energy transferred in a nuclear explosion to stop the debris of the asteroid from just coalescing back together under its own gravity.

>>15124296
except that fucking logo

>>15124366
you know, it's actually good science, even if you're certain 100% you still do check it anyway, this is rare to see in modern academia nonsense. I rather have them use taxpayer more for these "dumb" experiments

Why does the Starship programme have so much SOUL

>>15124568
I wonder if he’s counting B7/S24 and B9/S25 as completed already or not

RS-25 gets a pass because holy fuck 453 s ISP, your engine is a fairly small portion of your total mass anyway. BE-4 does not.
>A-actually BE-4 is 250t while Raptor is only 220t so-
>The current peak thrust R2 operated at is 247 tons, so SpaceX is confident 250t will be achieved, which is “obviously essential to making SS work.”
This was a year ago as well.

>>15124561
It's not that easy in transportery

>>15124574
RS-25 had some insane operating conditions. 8.5 minutes of firing is 2 full Falcon 9 launches and returns. Apparently the final few Shuttle flights had next to zero refurbishment for the RS-25s

How the fuck does SpaceX expect to have Starship ready for Artemis by 2025 (2026?). Artemis needs like 8-12 Starship launches back to back.

>>15124596
Anon... Artemis I is a flyby. They're not landing.

>>15124598
Well, II is 2025, III will be later, probably much later. Dear Moon is this year, that's theoretically a much tighter schedule.

There were a number of interesting things to come out of it but I'll save those for a bit to see if any more context can be added over the next weeks.

>There is one extremely noteworthy tidbit that I have to share, though: according to the same sources, the meeting included statements implying that BFR would move from composite tankage to stainless steel tankage. It was apparently unclear if this was referring to just the Starship (BFS) prototype, all early boosters and spaceships, or a total program shift away from all-composite structures.

Yeah, approximately twice the size. It's not a super fair comparison since I believe the numbers are for a sea-level raptor, RS-25 has a much larger bell so it looks way bigger.

https://www.rfa.space/rocket-factory-augsburgs-first-launch-to-take-place-from-saxavord-spaceport/

I don't get why Shetland (North of UK) is a good place to launch rockets at all when Cape canaveral will cancel a launch over a stiff breeze? It pisses it down with rain there and it's constantly windy? Obviously the people know what they're doing but I just want to know the reasoning here.

its remote with I guess adequate infrastructure
would have to wait for more ships etc if they launched from mainland scotland

I don't expect dearMoon to happen before Polaris has the first crewed Starship flight in the third mission.

I’ve always wondered if these are just the personal cars of the workers/contractors or if SX just bought a bunch of company cars for industrial work. Funny to think of Musk shitting on F-150s but then buying a bunch of fords and rams and GMCs for starship stuff.

>>15124833
>>15124123
NASA PR is abysmal, so many talking heads, let the fucking tech and the people at the comms speak for themselves

I can't fucking wait for Artemis III when we'll have 4 different NASA PR people talking over the astronauts and filling every moment of silence as they step on the lunar surface with their babble, every historic launch and event is gonna be filled with PR people talking over it with a split screen so we can see their desk and their background audio in the feed, like during fucking DART

>>15124845
We have truly declined

>>15124737
there is a pastebin?

>>15124845
Fucking really hope this doesn't happen and they just focus on Capcom and Artemis astronauts and not have PR people talking over them

>>15124845
DART had a stream without commentary.

>>15124860
But did it have controller audio?

>>15124848
NASA having horrible PR goes back to their very inception. The ultimate example being Apollo 11, with it's awful hard to see slapped together at the last minute video feed and the astronauts being ordered to keep all conversation on the lunar surface as mundane and uninteresting as possible. I still maintain that had Apollo 11 had the sort of picture quality of later Apollo missions and had the astronauts been allowed to actually express themselves public perception of spaceflight would be far more positive. 650 million people tuned in to watch Neil Armstrong walk on the Moon and most walked away with the impression that space exploration is boring

>>15124865
I'm almost sure no.
But what controller audio could it have? The probe was probably on auto pilot at that point.

>>15124879
Truue, notice how popular the videos of Apollo 16 goofing off on the moon are in comparison, Apollo 11 was really dry

>>15124879
I really don't like the "one small step" quote and all the media commotion around it.
There are so many better quotes from Apollo, even on 11.

>>15124845
NASA is the circuses end of ZOG's bread and circuses scheme, so expect it to become more and more like televised sports, because that is ZOG's model for placating everyone who isn't busy working.

>>15124956

There's no way to know it hasn't happened already. For a decent amount of time there wasn't constant communications with astronauts in LEO. Once they were out of signal range who knows what they might have said

>>15124736
>>15124740
Yeah I know. The place was probably already a ruin even before the war and any engineers worth having would have already left for either the west or Russia already. I guess they could use the rubble as paving stones for the national space centre in Moscow as that’s the only way it realistically could contribute to space travel at this stage.

Didn't Elon once famously threaten to fire everyone even remotely connected to fueling Falcons if they didn't bring enough fuel?

>>15125072
sounds based, gets everyone involved actually interested in accomplishing the task instead of thinking what is or isn't my job

>>15125072
hahaha lol, is that true? I never heard that, though it must be if we are talking about Elon.
>enough fuel
They lost the center core of the maiden Falcon Heavy launch due low levels of igniter fuel if I remember correctly, don't know if that was caused due to some damage during reentry or the just forgot to fuel it completely. Elon is right in being mad as fuck, millions were watching that launch and they could've landed all 3 booster one after the other. I wonder if the curse of the center core will continue.

>>15125086
>>15125094
Yeah, it's in Berger's book. He made the threat because they didn't bring enough fuel one day and weren't able to refuel the core for a third time as a result after two holds.

>>15125178
Fair enough

>>15125184
NASA has always said that Mars is 20 years away, and according to Musk colonization would have started in 2021 or something.
I'm optimistic about Starship but it will be only real when it is real, and I place my bet for the first human on Mars at no earlier than the late 2030's, but probably it will be on the 2040's.

Is there any information on when will TOLIMAN launch more precisely than just 2023? I can't find any information on the progress of the telescope.

>>15125196
I cant find any diagrams of what the actual telescope will look like

The old timeline was waaaaay too ambitious. They assumed they’d have refueling and whatnot down in just a year or so. The biggest one, for me, is that they were willing to send Cargo Starships to mars with full and expensive ISRU payloads without doing any EDL tests on mars first. Most of all, they didnt have the HLS contract. A more realistic timeline seems like

>2023
First Starships reach orbit
>2024
Refueling tests and whatnot
>2025
Starship does more stuff. Uncrewed HLS demo
>2026
Crewed HLS. ALSO, mars EDL test with light payload
>2027
More Starship refinement
>2029
Cargo Starships land on Mars
>2031
Crewed Starships land on mars

The latter timeline seems disappointing but understand that NASA did not expect to go to mars until NET 2039. Anyways, some wildcards include
>Polaris 3
>DearMoon
Etc.

You think other countries will use Starship for their own National lunar programs?

For example the Saudi’s want to have a moon mission, they could just charter a starship and have Saudi Astronauts land on the moon

>>15125222
I found this one in a news article.

>>15125265
Is there any historic for countries paying for foreign agencies just to get a citizen to space?
But generally I don't expect it to happen unless something very fundamental changes in spaceflight culture.
Having your own launch vehicle and launching your own astronauts is a huge moment of national pride, while having your astronauts catching a ride with someone else doesn't has the same charm.

>>15125265
That'll depend on international relations and whether or not the US gets an imperialist shine in its eye towards moon colonization

>>15125275
All of Europe.

>>15125280
Saudi Arabia is a part of the Artemis Accorda and they plan to leave the moon treaty because it’s goals are not comparable with the accords

>>15125275
>>15125281
Imagine waking up every morning and realizing that no organization on your continent has ever developed a manned orbital launch vehicle.
Goodnight.

>>15125287
It'll hinge on whether they throw their lot in with the US or China. They're trying to play nice with both at the moment but that won't be possible forever.

>>15125293
You could be talking about South America, Africa, Oceania or (non-Russian) Europe lmao

Does anyone have the pic of all the Chinese rockets with long march 9 (the redesigned starship clone) front and center?

>>15125296
Makes me wonder. The Russians are trying to throw in with the gulf states and Mexico, many of which are Artemis accords signees

https://theins.ru/news/258335

...and that's another successful launch for the LM-2D, this time carrying a rideshare grab bag of fourteen smallsats.

>>15125293
Europe has developed Man rated orbital launch vehicles and many Habitable and Inhabited spacecrafts. The last step was redundant.

>>15125305
The Gulf States have no issue with pursuing closer ties with China while also being Artemis Accords members. Russia's just trying to rebuild some of the relations they've lost of late.

>>15125309
That's a looong takeoff

>>15125309
Long March 2, 3, and 4 are so aesthetically pleasing

>>15125299

Indian rockets are cool

>>15125323
LM-2D only manages about 1.3gs of acceleration at liftoff. It's not really in a hurry to get anywhere.

It also seems there's some interest in actually live streaming some of these launches, so we might get something better than second hand posts via twitter sometime in the future.

>>15125226
Better than the guy who thought “hundreds” would be launched to mars by 2026. After starships first orbital test I’m gonna post my collection of screenshots of stupid shit retards have posted ITT.

>>15125358
Is the collagefag still here? I can't quite remember what he posted.

>>15125226
Timelines change depending on development of the project. Musk makes predictions, he doesn't prophecize things. Not only does he make predictions, he makes things into reality, thus he's the best knowledge/prediction power we have in the entire human repository of knowledge because he has the unique seat of authority of not just being in rocket industry, but actively developing the technology to make his vision come to life.

Why is /sfg/ so pessimistic about Starship?

>>15125372
Kind of hard to be optimistic when the orbital launch is taking so long to happen. What the fuck happened to rapid iteration? Also, I'm almost sure the Falcon 9 wasn't as good as they initially hope, despite being better than all the competition.

Why do the Chinese have so many rocket variants?

>>15125386
So you’re gonna talk about how disappointed you are with SpaceX then? Lol

>>15125391
Long March 2, 3, and 4 use the same core stage but with either none, a hydrogen, or a hypergolic third stage. China also considers a 2 booster and a 4 booster rocket as being different variants.

Also Long March 7 and 8 are basically the same too

>>15125395
Honestly I am optimistic for Starship, just not in the way most Musk fags are.

>>15125372
>sfg is one person

https://www.youtube.com/watch?v=MMkIh7cE1eo

>>15125423
>sneedy chuckro

>>15125401
Long March 8 is so funny. From what I gather, they designed the rocket with non-staged side boosters because they want to reuse it but didn't want to bother developing a bigger core stage. They flew it once in that configuration. The next and most recent time they flew it a year later, they omitted the boosters.

>>15125391
Wait, is that Dragon 1 on the top? I know they're making a similar capsule but I think I've seen that render before.

>>15125237
I'm guessing the first Mars landing will happen in either 2031 or 2033. Despite the pessimism of many on sfg, I believe that once Starship gets to orbit, development and solving of stuff like EDL, Orbital Refilling, reuse, etc etc will proceed quite quickly, especially when the Florida launch sites and the floating platforms come online. Not going to predict what will happen after 2023, but I think once the first starship launch actually happens we'll see a SN8-SN15 style series of orbital tests throughout the remainder of 2023, with full success possibly being achieved by the end of the year.

>2023

Everything in this image is like if you gave a talented artist the prompt to draw realistic spacecraft, but they have the average American's knowledge of anything space related minus Shuttle. The vaguely ISS shaped station, the slightly tweaked Soyuz, and rockets that are just... rockets, long core with a fairing and side boosters

>>15125372
Because people are angry SpaceX isn't risking nuking their only starship launch site and setting back progress 2 years.

>>15125463
Meant to put a ? in 2024, because I have no clue exactly when things might happen in that year

>>15125372
It’s literally just bait, trolling, and the typical attempts at contrarianism and self pity

>>15125372
Its not. There's one or two perpetual anti-Musk guy, who ironically posts like that or is actually bought into that sort of mentality.

For most, its just business as usual. Also tourists from other 4chan boards come here sometimes. Other boards have high number of redditors who parrot the [current thing]. Which is to hate on Musk.

>>15125372
People are just impatient. We’re only two weeks away guys!

>There also was a good deal of politics in another issue: where to launch the Shuttle.
>Though NASA had an obvious interest in using the Apollo launch facilities at Cape Canaveral, the Shuttle was not the Saturn V and plenty of people in other areas of the country were ready to propose that they could offer sites having unique advantages.
>Some 20 states went on to propose over a hundred possible locations, though many bidders had little idea of what NASA needed.
>Mill Creek, Oklahoma, invited NASA to use its town airfield; Brownsville, Texas put in a word for the nearby Cameron County Airport. Another bid came from Michigan’s upper peninsula.
We could have had Boca Chica Shuttle, or potentially even Duluth Shuttle.

Why don't they get another droneship and land the side boosters both downrage while expending the center core? should give the falcon heavy a sizeable payload improvement shouldn't it?

>>15125597
They have multiple droneships. They can land side boosters on droneships if necessary. However there hasn't been a necessary payload to demand such.

>>15125621
Do they have two on the east coast though?

>>15125623

OCISLY and A short fall of gravitas are both on east coast. They also have Just Read the Instruction as well, which is on west coast, but they can move from west to east and east to west if necessary since a payload that requires triple drone landing would be extremely rare if ever.

I wonder how capable FH is in that profile. Could it bring Orion to the orbit SLS puts it in?

>>15125650
Easily. Orion being launched on SLS isn't because Falcon Heavy isn't capable. Its purely a political tool to sell congress on jobs program.

Can't wait for the chinkstation to perform ethically questionable experiments that would never be flown on the ISS.

>>15125825
There's no universal ethics. If China kills 100 mice in 1 year to obtain knowledge of sex and birth in space, would that be worse than killing 10 mice each year over 10 years? What about killing 1 mice every 10 years the next 1000 years to the same level of knowledge? China will operate faster and have more experimental failures but with faster results and faster fails in shorter time vs longer time, is that really worse?

They had a frog egg experiment on Gemini 8.

Anyone got the webm from the plane as it released Unity and you could see everything vibrating and flexing?

Article btw: https://www.theguardian.com/science/2023/jan/14/richard-branson-virgin-galactic-passengers-space

"In one of the cases filed in December 2021 by Mark Kusnier and other investors the complaint states: “Unity and Eve were so rickety that every flight could be their last. Cracks appeared on Eve’s wings after every flight, and some were not fixed – so much so that a Virgin Galactic employee said the wings looked like spiderwebs or cracked eggshells.”"
