Alright boys, just ordered a massive haul of stamps from four different sellers.
290 stamps in total for around 35€, with atleast 150 of those being space stamps for certain. That's only 0.12€ per stamp.

>GMT
Need to use local time zone for launch locations.

>>14584694
that's too much work plus it's retarded

>>14584696
Its less work because rocket launch manifest are published under local time zone. Someone took the time to convert it into GMT and now we have to re-convert it back to local time zone to get an accurate timeline. Why is this a thing? No reason for it to be GMT.

>ROSWELL, Ga. (AP) _ Columbia Pictures has bought the first advertising to go on NASA’s Conestoga rocket, which will be launched in May.
>Columbia will promote ″Last Action Hero,″ a movie starring Arnold Schwarzenegger, with a spot on the fuselage of the 52-foot rocket, said Space Marketing Inc. of Roswell, one of the companies involved in unusual alliance between the space program and private industry.
>Commercial backers of the rocket launch have been trying to attract advertisers to promote the launch and are asking $500,000 for the spots. Some advertising executives, however, have expressed skepticism over the program, saying no one will see the ads when the rocket is in space.

The falcon 9 launch tomorrow is gonna carry a globalstar 2 satellite and supposedly a classified military payload. What’s interesting is that it looks like this satellite is small enough to fit in the payload bay of an x-37 spaceplane so it’s either that or a really large spy satellite to take advantage of all that leftover mass

>>14584758
It is capable of dropping off that satellite then changing its orbit by a bit. Maybe it’ll go check out the Chinese station or one of their spysats

>>14584861
Seems that way, each informant group was a group of three, and only one of the three knew anybody in the next 'higher up' group, which was also a group of three, and so on. Any one cell could only reasonably rat out one member of the cell adjacent or up from them, so each cell could suffer a loss without being broken up entirely. At least from what I remember, it's been a couple years myself, I just remember it being several pages of explanation as to how it'd work.

there were rumors of a movie some years back. but you simply can't film it in this political climate... with the everyone-is-gay-in-the-future thing where it is made to be the societal norm. ie it isn't a choice

It's also pretty far removed from the social issues that it commented on by now. Not that veterans don't have plenty of problems coming out of the military these days, but we've come a long way from Vietnam.

SpaceX is targeting Sunday, June 19 for launch of Globalstar FM15 to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window opens at 12:27 a.m. ET, 4:27 UTC. A backup launch opportunity is available on Monday, June 20 at 12:05 a.m. ET, 4:05 UTC.

The Falcon 9 first stage booster supporting this mission previously supported the launch of Crew-1, Crew-2, SXM-8, CRS-23, IXPE, one Starlink mission, Transporter-4, and Transporter-5. After stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

A live webcast of this mission will begin about 10 minutes prior to liftoff.

That's the classical structure, with a 2D pyramid of cells. In the book, the computer-tech main character asks why they don't expand it to a 3D network for more efficient intercommunication with roughly the same degree of risk, and his old-school political dissident buddy goes "well shit, I guess we're putting you in charge of the revolution."

There will be a problem. The payload won't make it to orbit. Musk's luck just ran out.

Why does ULA never launch anything these days? They used to go about once a month but now it's just nothing for months at a time.

Let's be very honest again. We don't have a commercially available Mars transport vehicle. Phoenix may someday come about. It's on the drawing board right now. The NASA mission is real. You've seen it down at the VAB. We're building the station. We have all the engines done, ready to be put on the test stand at Jamestown... I don't see any hardware for a Helios mars rocket, except that he's going to take some methane engines and a space hotel and put them together and that becomes the Phoenix. It's not that easy in rocketry."

>>14585125
I really hope Helios BTFO’s NASA as a metaphor for real life but you just know they’re going to fail and need the US to save them because DUDE NASA!!!!

I'd just like to interject for a moment. What you're referring to as Orion, is in fact, SLS/Orion, or as I've recently taken to calling it, SLS plus Orion. Orion is not a launch vehicle unto itself, but rather another multibillion dollar component of a partially functioning pork system made useless by the SLS subcontractors, shitty designs, and Alabama river rocks comprising a gigantic scam as defined by the GAO.

Many taxpayers fund a small part of the SLS scam every day, without realizing it. Through a peculiar turn of events, the version of SLS which is widely mocked today is often called "Orion", and many of its victims are not aware that it is basically the SLS scam, developed by the SLS lobbyists.

There really is an Orion, and these people are seeing it blow up, but it is just a part of the scam they fund. Orion is the capsule: the payload in the system that allocates the government's resources to other districts that need pork. The capsule is an essential part of a launch system, but useless by itself; it can only incinerate astronauts in the context of a complete launch system. Orion is normally used in combination with the SLS boondoggle: the whole scam is basically SLS with Orion added, or SLS/Orion. All the so-called "Orion" debris fields are really distributions of SLS/Orion.

I've been thinking about this for an hour or two now.

What specifically about spaceflight makes it so prone to people just straight-up stealing the entire budget (or the entire budget multiplied until it reaches some new end point)? The thing with the launch tower is absolutely insane to me. It'd be the equivalent of the Navy buying a Virginia-class submarine and Newport News said, "Thanks for the 1.5billion, that was nice of you." instead of delivering a sub. I know people like to point at blatant cost overruns on other programs all the time, but this is just a whole nother level. How many billions did NASA spend on fucking space suits it didn't end up receiving and now plans to spend how many hundreds of millions more to rent a handful?

How? How the fuck does this happen?

>>14585159
Because it's "complicated", so they just make excuses

>>14585160
More complicated than making a nuclear submarine? Literally impossible. Those things are black magic. Even the fucking NRO always gets the satellites it pays for. No one fucks them. So why does this happen with NASA?

>>14585159
if NASA had as much money to blow as the DOD they'd just dump more and more into procurement programs that don't deliver and that's how you get the f35.

>>14585164
>more into procurement programs that don't deliver and that's how you get the f35.

You know this is a tired meme, right? There are almost 900 F-35s flying around now.

>>14584676
Cool story bro. Presuming you can force it to work to some extent it still can't scale for shit.

Drill a tunnel up a mountain.
Fill tunnel with compressed natural gas (or oxygen if your bawlin).
Shoot an inside out ram jet through your tunnel.

>>14585159
If you know anything, feel free to call the OIG Waste Fraud and Abuse hotline:
https://oig.nasa.gov/hotline.html

Otherwise it really does cost that much.

>>14585165
if nasa had program budgets in the trillions we'd have hundreds of SLSs launching too

>>14585167
>Otherwise it really does cost that much.

It does not cost 1.5bn to think about designing a launch tower. Not design a launch tower. THINK about designing a launch tower. That's what the OIG report basically said when it looked into this and they are still going to give these fucks more money. It's insane.

>>14584906
Was literally written by an angry faggot upset that starship troopers glorified authoritarianism and war. So he wrote a boring ass knockoff but this time it's an anti war book where space governments turn everyone gay and grow babies in pods. And the aliens weren't evil, they were just misunderstood. We can get along with existential threads if we just sit down and listen to what they have to say.

If you think that book was better you have shit taste.

>>14585168
You appear to have fallen for the "F-35 cost $1.5 trillion" propaganda.

>>14585175
yeah yeah, just like "sls will cost $4 billion per launch" is propaganda because you're amortizing one-time costs over every launch of the program.

>>14584962
You see anon, it wasn't in orbit. They wanted overhead coverage of the target area but a geostationary orbit is far too distant. So instead they position themselves overhead and use active (massless) thrust to remain in space. When the engines fail they fall.

Now when your dogfighting in space and you want to turn you cant just turn like in the game asteroids, instead your controls position an projected a micro black hole outside your ship that you swoop around. Actually using the black holes as a weapon is locked out in firmware as this is against the interspecies aggression treaty, it's only allowed to be used to make dogfights look cooler.

>>14585007
IDK man, the left is a little unhinged.

>>14585172
>nonce has a retard opinion and doesn't understand the text

Why am I not surprised?

>>14585172
Mad

>>14585176
The difference is that SLS will launch less than 20 times ever while hundreds of F-35s will fly for decades each. Expendable HLVs will never ever amortize as well as a mass produced fighter jet. That's half the reason people keep proposing HTOL SSTO spaceplanes, to get that same sort of aircraft lifecycle. The other half is because TBCC is fucking awesome and fast planes are constrained by the laws of aerodynamics to look cool.

>>14585176
The $4.1 billion cost for each of the first four Artemis missions is just for the procurement of the SLS rockets, Orion capsules and the cost of the launch operations for those missions. Past/future R&D and one time expenses like the launch facilities are in addition to the $4.1 billion for each launch.

DON'T CRY OUT LOUUUUUUUD

>>14585143
sus

>>14585199
The high cost of the RS-25 on the Shuttles were amortized over their dozens of flights. The first four SLS rockets that cost over $4 billion use leftover engines from the Shuttle, once those are all expended they will have to use new expensive engines that are dumped in the ocean with a single use.

>>14585185
>that pic
kek, that's what will basically happen when there are some hundreds or couple thousands of people on Mars by 2050 instead of a million like Musk "promised", therefore fraud.

>>14585170
That report is absolutely wild.

The first launcher was basically hacked together from something intended for the much smaller Ares I but never completed, and the contractors repeatedly fucked up every step of the way.

The worst of it is reserved for NASA itself though. The line you see repeated most often was "the requirements changed." Also they covered up the delays:
>One challenge to holding contractors more
accountable is that because contractor milestones are developed during the project and not prior to awarding the contract, as technical challenges arise, NASA can reprioritize cost goals and milestones for the contract making it appear as though the contractor is performing well even when the contract is over budget and behind schedule. For example, Kennedy personnel responsible for rating Vencore’s performance stated that even though design work was over budget and behind schedule they believed the contractor performed well due to the obstacles they had to overcome. As a result, Vencore received “excellent,” “very good,” or “good” ratings despite the ML-1 project being significantly over budget and behind schedule.

>>14585212

The technical term is "bikeshedding". People pay attention to what coffee the cafeteria uses, not so much what suppliers are used.

>>14585306
>what suppliers are used.
...what suppliers are used for the sub-assembly that holds the satellite together. Obviously they care if the coffee is Nescafe or Starbucks or something.

>In his description of the law, Parkinson used the example of a committee meeting discussing ways to finance three projects:
>A £10 million nuclear power plant.
>A £350 bike shed.
>A £21 annual coffee budget.
>The meeting starts with members discussing nuclear energy, but most are ill-informed and the project seems too complex to facilitate meaningful discussion. The committee then moves on to the bike shed and since many ride to work, there is more animated discussion regarding its financing. Lastly, the coffee budget is discussed. Everyone drinks coffee, so the colleagues spend the rest of the meeting talking about their favorite blends and the allocation of just £21.
>At the conclusion of the meeting, nothing of significance has been achieved.

>>14585200
Reminder that its actually much worse than 4 billion
It doesn't include the dev costs
Or the operation costs
Or the tower costs

>That being the molten salt cooled reactor they tried on the sea wolf class sub.
Seawolf didn't have a molten salt reactor. It was sodium-cooled. It was axed because it's advantageous to swim through your coolant. Rickover was right about PWRs being the only sane choice for submarine reactors.
>The commercial sector within the US is rather stagnant, but outside Korea, Russia and China never stopped building reactors
China is the only one who's doing any real R&D on advanced reactor designs. Rosatom is on life support. Korea was doing a good job at maintaining their PWR industry but that's been in danger in recent years.

New Mars Guy video out. A piece of foil steals the show from our beloved roggs.

Interesting they actually showed this, you can clearly see that there was a likely much bigger satellite on top before.
So what are your guesses on the actually important payload, Zuma 2: this time it worked or something new?
Also is this what classified space autism looks like, lightweight support structures with big rods, or did SpaceX make the separator this time?

How does SpaceX expect to refly Superheavies so fast? Falcon 9’s not only undergo maintenance, but they also have a lot of inspections to make sure the welds and whatnot aren’t gonna fail.
Relaunching without checking for these issues is just asking for a failure.

>>14585932
well then they will fail and fix so until it doesnt
or are you saying its impossible to build so it doesn't need frequent maintenance?

>>14585932
By working for months and years until they can do it so fast.

>>14585938
Kind of both but not even just the maintenance, simply skipping steps seems sketchy. Even a 2 month turnaround time with a fleet of 8 boosters still allows for 1 launch per week.
Also some failure modes are worse than others. If a Superheavy takes out the launch site, it’s game over.

F9s are 1000kms away at sea which takes atleast few days. Then it takes few more days to bring it from the dock to hanger. Then few more days from hanger to launch pad.

That part of the equation is shaved of entirely saving already a week or so. Then you have to add in the intermediaries between those, which double the delays on f9 but is not present in Starship.

This is just the process simplification alone that will save them weeks off of current f9. Then the vehicles are designed to be more robust, engines area designed to be more robust, hence even less time required.all of that will reduce the time further on.

This still doesn't lead them to hourly rate but will likely bring it down to few days or daily rate. To get from that to hourly requires regulatory changes, demand and operational experience. That will take a while.

>>14585300
If they gave up on a separate cervix module propulsion system and made Orion permanently attached to the ICPS/EUS it would be a major improvement over Apollo... if only they had hydrolox propellant depots in lunar orbit.

lmao what

>>14586015
Either you can't read or you meant the EME conjunction as the opposition transfer would require more delta-v, either way your point is not even close to being accurate. According to Elon 2019 Starship would have ~7 km/s of dV with a 100t payload, furthermore it can do direct entry thus saving the most of the dV required for capture and descent, including during the Earth return portion.

Leave this site at once

had a dream that i was watching a retarded ksp streamer who thought that gravity assists meant you had to orbit the planet you were slingshotting off of so he sent a probe to orbit venus and then got mad when it didn't have enough delta v to go to jupiter from there. i blame reading too many stupid /sfg/ posts.

>>14586063
Starship + Super Heavy wouldn't be able to reach orbit if they didn't have a delta-v of at least ~9.5 km/s, but I guess everyone at SpaceX and most of NASA is intent on keeping the scam going, right?

according to elon you need a 4chan gold account to be able to use the catalog function

Shills or trolls doing their shilling and/or trolling...

There were genuine Apollo conspiracies. For instance the world was told that all communications happened in the clear but the medical telemetry signals were designed to be alternatively used as an encrypted private coms channel. All these recordings were intentionally destroyed to cover up such a terrible secret. The events were largely scripted but were portrayed as being unscripted.

Apollo 12 was a PR stunt to show Russia that we can do a pinpoint landing anywhere we want on the Moon, while it happened to work out alright in the end they in fact landed in the wrong spot on the wrong side of Surveyor 3 and could not see it out the window. People were freaking out and they did an unscheduled eva opening the upper hatch on the lunar lander poking their heads out and spotting the Surveyor before closing the hatch, doffing the space suits and pretending this is where they always planned on landing.

I just wish they would admit this shit before everyone involved dies, it's nearly as cool of a story as Apollo 13 but they are still afraid of the reputation hit for some reason.

Yes we are talking about the opposition transfers, and Starship only has the delta V for the long (750 day) EME opposition transfers. It does not have the delta V for the EMVE opposition transfers which take almost a year less time.

>>14586550
When the appropriate sacrifices have been received.

>>14586618

Imagine a tetrahedral cell structure of a predetermined size, with each terminal vertex acting as its own executive cell. You start with four organizations all operating and expanding independently until their networks link in the prearranged design, and this joining of resources is an organic lead-in to whatever "phase two" is for your movement. Someone in Cell E puts in a request to begin recruiting for an F-layer subcell but gets a response from command of "negative, you've reached the boundary of your sister organization, your neighboring cell is now G-16 of Vertex Gamma."
The trouble would be intercommunication between the four executive cells. Maybe the chairman of each reports to a fully-external executive individual, with the four chairmen not even knowing one another.

NASA/Aerojet isn't seriously considering a EMVE opposition transfer because it would require even more than a 11 launches to send up enough drop tanks for a NTR and those transfers aren't consistent so if they miss the transfer window the entire mission has to be reworked. Still Starship would still be able to do one in 2039 as aerocapture would off 5 km/s of delta-v from the round trip, except that won't ever happen because opposition transfers are retarded and SpaceX will already be on Mars before that date.

I took the FAA medical before anything else and passed the color vision test, so I figured I was good to go.

Did you guys find the fountain of youth? How is it possible to be so new?

To keep it topical, what’s the one thing humanity will discover during the exploration of the solar system that will be the most outrageous and hardest to believe is real? Nothing?

And during this coming age of exploration will we get any legends about mysterious places or artifacts that are somehow undocumented? Or will video evidence make facts and fiction too easy to distinguish?

Is Starship in any way derived from Falcon 9? Because F9 itself has heritage from Saturn V (engines) which itself has heritage to the V2

Only thing outrageous would be alien artifacts or multicellular life on other bodies

>>14586919
It’s really hard to say. Most of the stuff we have a hard time believing is real on Earth is stuff from ancient civilizations that have long since faded away. Unless we find ancient ruins on Ganymede or something, probably nothing

With Artemis 4 being delayed to 2028, and Artemis 5 to 2029, what is the chance SpaceX just flies people to the moon on their own?
Artemis 3 lands people in 2025 or probably 2026, but then there’s nothing for three years. What then?

i don't think there's any real inheritance in raptor from merlin, different cycle, different injector, different igniter

Not even that. Democrats are going to get destroyed in 2022 and 2024 elections. Musk sees which way the wind is going to blow for the next decade and he's getting ahead of it.

eggcellend :DDD

Doing some math right now. It takes 3.2 km/s to reach a trans lunar injection. 2.5 km/s to land straight from this (no braking into orbit, etc). It takes 2.5 km/s to launch straight from the lunar surface back to Earth.
So assuming it takes 30 tons of prop to land from the bellyflop, and Starship masses 120 tons, and carries 50 tons of payload, we have a total starship DRY mass of 200 tons.
Starship carries 1200 tons of propellant, so at an ISP of 375 seconds (conservative RapVac value), we have a delta V of 7.1 km/s.
The total round trip Delta V from LEO to Earth return is 8.1 km/s. A fully fueled Starship with 50 tons of payload can go to the lunar surface and return AS LONG AS it has a 1 km/s “boost.”
This translates to a parking orbit with an apogee of 5500 kilometers, which has an injection Delta V of 1 km/s.

A final part of the puzzle is refueling in high orbit. A 120 ton tanker starship with 30 tons of landing prop, and carrying 100 tons of fuel (total dry mass: 250 tons) needs 100 tons of extra propellant (375 second isp, again) to reach the 250X5500 km parking orbit. That translates to 1 LEO tanker + 1 HEO Tanker. 2 launches for every 100 tons of prop for our Lunar Starship

Thus, a lunar Starship needs 24 tanker launches to fully refuel in elliptical Earth Orbit in order to land on the moon and return. 25 launches total.

Long story short, Starship can go to the moon and back as long as it refuels in an elliptical, 250X5500 km orbit with 50 tons of payload. This requires 24 tankers, for a total of 25 launches.

It also depends on the level of generality you consider his actions at. “Man does something” and “Rocket launches successfully” are not extraordinary. “Man builds first spacecraft potentially capable of allowing colonies on other planets” is extraordinary. However, there’s no uniquely correct level of generality, so maybe it really does just depend on context and perspective.

Current progressives are dead end for the democrats. Its gotten so toxic that no one likes them anymore. They're alienated everyone.

>>14586935
Starship/Super Heavy is reusable, like F9.
Super Heavy has grid fins like F9.
That's about it for things it is inheriting from Falcon.

Aluminum vs stainless steel, kerolox vs methalox, engines totally different, TPS tiles on Starship, both stages unpainted (so far), etc

They're 2 completely different rockets, the chain of inheritance from the V2 has been broken. In a way it's fitting that the first interplanetary vehicle not be derived from a weapons system - hopefully this means earthers(derogatory) can leave their petty wars to their shitty dirt ball instead of allowing conflict to continuously hinder expansion into space.

But why couldn't he just keep silently donating to both sides and publicly stay relatively neutral? Would avoid all the shitflinging and alienating of half his customer base.

>>14586783
Why not wait until the space force has combat troops or at least space drone operators?

A final addendum to the original post

If Starship Tankers can put 150 tons to LEO instead of 100, this changes things. A 120 ton tanker with 30 tons of landing prop and 150 tons of payload (propellant), you have a vehicle with a mass of 300 tons.
In this case, the number of tankers is split into 2/3. Instead of 24 tanker flights, there are only 16. Cool.

>>14586935
I think there was something about flight software being derived from F9 for the early hops but I don't remember if that was just a rumour and they could be entirely rebuilding it for the final thing anyways.

Democrats don’t like billionaires even though a lot of their politicians are rich as fuck. Bezos is a frothing democrat but he still gets hate.

Imagine pissing off your dad, who just happens to be one of the most powerful men on Earth. Anyway, thanks for driving Elon to the right in what is likely the most effective way possible!

He tried that in 2015-2018 (Hillary donation, GOP state and congress donations) and the Democrats had a gigantic freak out about it which green lit all the hit pieces from their media.
The Dems have a obsession with political purity while the GOP is all too willing to look the other way to get their single issue through.
