You guys like space right?
How would you sell it to someone who has top tier qualifications but no interest in space?
What's the motivation to go up there when you can get paid better down here with less risk. Is it purely the fame aspect?

>>12567580
The abundance of resources is what attracts me to space. You can put solar panels in space and beam the power back down with microwaves to anywhere on Earth. There are also many resources to mine. Heavy industry will soon be more in space than on earth. No one to stop you from building your nuclear reactor on the moon!

Oh sure, I like all that. I meant on the individual level why would you want yourself to go to space. You send expendables to do that dangerous work.

That's many many years into the future though Anon. I'm talking about now when you're only getting up there on a govt. or private company ship which is still going to exert control over your activities.

There's basically no good arguments for colonizing space. It's a hobby.

asteroid mining, yes i know about supply and demand will crash the price, its still worth it, it would make materials that used to be rare common, therefore technologies that were only dreamt of a reality

0g organ printing

0g to 3g sports and training

and the best one

the incredibly utterly exxagerated rate of scientifical adfvancement that would occur if you have a colony made of people who come from wealthy educated families, excersise often, are disciplined and are extremely interested in science with no low lifes to distract them.
Like, imagine xx century tech? thats nothing, this would be like 1000 times more.

IT will be like to the XX century tech what the xx century tech was to all the rest of the human technology story history of advancemetnt

>>12567580
0g allows printing organs literally molecule per molecule, literal instaprint of any structure forever, a literal instant end of all disease

sports

nowadays even if they dont admit it all sportsmen professionals that are professionally high use harsh environment training
causey, if you train 100 in environment harshnees 2, but race is in envoiroment harsnes 1, you train twice as hardernor.

so
instant forever argument of mine i won and youre an idiot forevcer who deserves to be punished if you disagree after my objective purposeful demonsration that athletes do absolutely 100% confirmor to seek harsher environments to train

nothing can be harsher than a high g low oxygen space station

therergorerfore, all athletes will have to go there yes or yes or lose, tjhis is not a discussion im telling yopu the objective reality and you should make me a monument for taking the time to answer

Elon was always an optimist but in the end and after a few design revisions his main idea always materializes.

ENTER Supermegaheavy Starship

>>12568512
This but using methalox (to avoid hydromeme density) and conventional nozzles (to pack in more engines and get more efficient thrust with less dry mass) and a cylindrical body (for ease of construction and TPS simplicity) and an additional reusable first stage (because SSTO my penis).

>>12568615
Connect 4 of those in a star configuration

>>12568615
Meh, going to an 18 meter diameter and reusing all the same tech developed for Starship (albeit at a slightly different scale but all the techniques are proven) would offer much more performance gains (at least 4x the payload to LEO etc) with much less complexity and the same generally favorable reuse profile as 9m Starship.

You will never have a chin. Also Elon already learned his lesson with FH and stated SS 18m is the next step after Starship so get ready to cope.

>>12568713
Other anon here. Putting multiple busters together is very hard. Spacex had a lot of trouble with it and the result was not that good compared to what they could have achieved by going straight to starship.
A small F9 fairing is a big limitation for FH and would be an even larger problem with 3 starships.

>>12568704

>>12568704
It's sad that the rest of our solar system is sterile. I can't imagine the disappointment of the scientists who thought Venus was a lush world only to discover that it's a barren and toxic wasteland. It must have been awful being the astronomers of the 50s and 60s who gradually came to realize how alone in our solar system we are.

>>12568742

you people are retarded here

>>12568776
Even his description of a "dead planet" still has moss growing on it... how sad it is to be all alone. We must expand life to other planets and create the friends kind of solar system we dreamt of.

>>12568785
Anything rounded by its own gravity is a planet, until the brown dwarf transition point. Fuck urf and fuck arbitrary non-physical definitions.

>>12568785
Sick burn. I bet you're the smartest kid at your middle school.

>>12568742
Genuinely, it's a continual spirit killer. The more we look the more it crushes any hope of not being alone within the bounds of what we can reach, now we've fallen so low we are unironically saying "w-well maybe there's microbial life miles under the ice in Europa"

IAU Resolution 5A: Definition of a Planet in the Solar System

Contemporary observations are changing our understanding of planetary systems, and it is important that our nomenclature for objects reflect our current understanding. This applies, in particular, to the designation “planets.” The word “planet” originally described “wanderers” that were known only as moving lights in the sky. Recent discoveries led us to create a new definition, which we can make using currently available scientific information.

The IAU therefore resolves that “planets” and other bodies in our Solar System, except satellites, be defined into three distinct categories in the following way:

1. A “planet”1 is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit.

While planets have to be nearly spherical, they usually bulge at the equator, thanks to the fact that planets rotate. The Earth's diameter at the equator is about 12,760 km (7,925 miles), while from pole to pole it is about 12,720 km (7,900 miles). Scientists estimate that for a rocky body, hydrostatic equilibrium will happen for an object that is about 800 km (500 miles) and has a mass about 1/12,000 that of the Earth (Ceres is about 950 km and has a mass about 1/7000 that of Earth).

>>12568778
It's not a good newspaper either

>>12568790
Part “a” eliminates satellites of the planets as potential planets even if they are “round.” Part “c” is the major difference between the original draft resolution and the one that passed. This eliminated the Main Belt asteroid Ceres (only one of many asteroids) and Pluto and 2003 UB313 (two of many Trans-Neptunian Objects) and eliminated the possibility of there being dozens of other planets in the near future.
2. A “dwarf planet” is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2 , (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

In the original resolution, “dwarf planet” was not an official IAU term. The terms “terrestrial” and “gas giant” (or jovian) are not official IAU terms. This resolution then creates a new class of objects that includes Ceres (and possibly a few other Main Belt asteroids), as well as Pluto and other large Tran-Neptunian Objects.
3. All other objects3 except satellites orbiting the Sun shall be referred to collectively as “Small Solar-System Bodies”.

>>12568837
Personally I think we should just get rid of the term planet and classify celestial bodies like how it's done in space engine

>>12568790
The term “minor planet” will no longer be used. Small Solar System Bodies include asteroids and comets. While most known asteroids have orbits between Mars and Jupiter in the Asteroid Belt, there are groups of objects that orbit in other parts of the solar system: Near-Earth Asteroids (NEOs), many of whose orbits cross the orbit of the Earth; Trojan Asteroids that share the orbits of several of the planets (Mars, Jupiter, and Neptune); Centaurs, whose highly elliptical orbits cross the orbits of the outer planets; Kuiper Belt Objects, objects in orbits beyond Neptune's orbit and that orbit in a relatively flat disk between 30 and 50 AU (30 to 50 times Earth's distance from the Sun); and Trans-Neptunian Objects (TNOs), objects that have orbits beyond the orbit of Neptune (KBOs are a subset of the TNOs).

1The eight “planets” are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
2An IAU process will be established to assign borderline objects into either dwarf planet and other categories.
3These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

Hop when?

>>12568837
I know what the IAU definition is, niglord. It's a set of hasty back-rationalizations to maintain the status quo masquerading as a set of physical criteria.

>>12568805
shut the fuck up you are a stupid fucktard I will fuck you up

>>12568859
IAU Resolution 6A: Pluto

The IAU further resolves:
Pluto is a “dwarf planet” by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

One issue that has been raised is: Are “dwarf planets” planets or not? In a statement by Iwan Williams, the outgoing IAU President said: “To the question is Pluto a planet, you can now give two answers. No, it is a dwarf planet; and yes, it is a dwarf planet!” While there is a general feeling that this was not the intent of the people who voted on this, it is not explicitly ruled out in the resolution and probably will be one of the many aspects that will be discussed over the next few years as debate on this issue continues.

Supposedly yes (if you trust NASA's Apollo cost estimates). The Saturn V cost $50B in 2020 dollars to develop compared to the SLS $20B. However, the Saturn V was estimated to cost $1.23B per launch to deliver 48.6t to the Moon while the SLS is projected to cost over $2B per launch to deliver half of that

There is also the fact that Saturn V was developed almost from scratch while the SLS is building upon preexisting Shuttle architecture. If we add Shuttle development costs to SLS, then the total development cost would make the cost of the two rockets more equal

this is not an exaggeration, there's a bit in aurora where he mentions that 30% of the ship's population is transsexual

>>12569301
Yeah something like that, and it's pretty much as solid a case as you're gonna get. The little guy's the fastest spinning large object in the solar system (which is why it's shaped so weirdly); and then there's a bunch of similarly fast spinning objects with the same composition, in a similar orbit. Statistically speaking, it's (probably) unique, all the simulations of the kuiper belt say there was only a 10%ish chance of something like it happening in the first place.

These are all unspectacular but necessary experiments that will enable future space exploration.

Honestly the more I read about the Dynetics lander the less I like it. It can only hold 2 people for 1 week or 4 people for a few days. It also lacks an airlock and requires the cabin to depressurize on every EVA.

Starship is neat but it requires at least a dozen tanker flights maybe more for every lunar sortie. It also needs hundreds of tons of propellant to be transferred, which has yet to be demonstrated. However it’s great that it has insane capability and landing just one on the surface gives more room than the entire ISS.

National Team’s Lander is definitely the most safe bet. It only needs 3 expendable launch vehicles to be assembled, and it does not need dozens of flights per sortie (looking at you Starship). It’s only partially expendable, which is not as bad as people talk about on here. Even better, the descent stage could be refueled with Hydrolox from the surface and function with a “bare” ascent stage as a 100% reusable lunar lander.

If I was NASA I’d select the national team lander just because it’s “safe” as an investment, but also fund Starship because 1) It’s fucking huge and 2) SpaceX is going to land on the moon later anyways, so why not help them out a bit.

>>12569396

the more research we do the more it is becoming clear that male and female are different neural architectures, and most tranoids have the architecture of the sex they want to be. Once we can modify bodies or keep brains in vats it's basically a non-issue.

>>12569630
the part where you need a dozen tankers flying for every expedition. seems like you just need 1?

>>12567815
there's no "good arguments" for 99% of the things people do, if you just want to be alive then you could live in a 2x2x2 meter box eating nutrient slurry, but that's not a life worth living

>>12569637
you can't fully refuel a starship with one tanker, you need several tanker flights, this is true for the regular version too

>>12569636
imagine being insane enough to believe this

>>12569647
didn't know that. guess it makes sense since starship is like 1/4 payload. What sort of fuel to payload ratio would the tanker have? It's only going to a single orbit so it doesn't need range beyond that. can they get away with a lot more?

>>12569636
>make and female are different neural architectures
True.
>Most tranoids have the architecture of the sex they want to be
False.

>>12569591
Serious question: what if starship lands on unstable soil?
It's so tall it can fall sideways pretty easily.

>>12569662
I mean /actual/ tranoids. Like, maybe 1 in 5 is actually trans, most ftms are just lesbians, most mtf's are just agp's

>>12569647
Honestly no one really knows SpaceX’s plan. A starship with a full tank still falls short of the Delta V needed to land a payload on the moon and come back up.

It seems like SpaceX is planning on using a dedicated “Reufeler” to top off Lunar Starship’s tanks. Presumably Lunar Starship launches into LEO but then pushes a bit further out to around 3-4 thousand kilometers. A second launch carries an empty starship without wings or legs into LEO. This starship is met with 12 launches until its tanks are full. It then boosts out to a few thousand kilometers and meets with the LunarShip where it transfers its fuel. Maybe the Refueler boosts down to LEO and is topped off again? Is it expended? Either way, a tanks full LunarShip with a “boost” of 1 kilometer a second DOES have the Delta V to reach the moon, enter a NRHO to meet Orion, land on the surface, and return to the NRHO. This is all speculation but google has a lot of neat speculation on the issue.

>>12569661
Starship is its own second stage, it can lift as much fuel as it can anything else, I don't know if its volume limited though.

>>12569647
Doesn't Starship only need like four refueling flights to have it's full 8+km/s of propellant? Four launches can get one Moonship to the Lunar surface and at least back up into Lunar orbit afterwards. Hardly what I'd call "dozens" of refueling flights.
>>12569675
No, the brain structure of gender dysphorics does not look like either a male or female normal, their physical appearance will never alleviate the symptoms, certainly not as well as batteries of anti-anxiety and anti-schizophrenia meds has provably done.

would be so much easier with a d*pot. can send up all the fuel ahead of time instead of having astronauts putter around earth for a day or 8 as they refuel starship. just dock, fill the tanks, and go

I think that’s the plan. You have a depot sitting in an elliptical Earth Orbit that is topped off by a “Refueler” which is in turn topped off by a series of Tankers in LEO. Even if it takes 24 launches per lunar sortie, 1 Starship every other week is sufficient

using medieval level technology, even before rifling and muskets, would it have been possible to make, using the chinese gunpowder available at that time, a rocket launcher that propelled soldiers over a wall and have them use a gigantic parachute made of fabric? this would have been a huge advantage, you could send them at night and infiltrate the castle they wouldnt have been able to get them all

Can you put a silencer on a rocket? I'm pretty sure there were some early attempts at parachutes going far back, though they tended to kill their creators.

>needing a cuckrope to go outside the ship
I think it'd be scary, but also exhilarating. Floating disconnected, a spaceship unto yourself.

I'm partial to this thing. At first I hated it but it's really grown on me. https://youtu.be/ywbfCBxZ2uA

If it worked at all they'd figure out some kind of long-term gliding variety eventually. Maybe even an actual glider.

>>12570158
right, but I'd still like a plan B in case the pack malfunctions

>>12570127
No. Rockets were god-awful until Tippu Sultan invented steel combustion chambers in the 1790s I think

Could it work?

>>12570179
remember these are the same guys who made the that "hoverboard"

>>12570184
They're also the same guys who came up with the ecorocket

Do it yourself you lazy nigger

>>12570170
Ideally plan B would be "stop laughing and come get me, asshole!" presuming you're not on a solo flight of some kind, but I understand you. I'd take the risk of going unleashed though, just for the thrill of it. Not like you need to be miles from the ship either, right outside is fine in case of emergency.
