Re: Sell the SLS/Artemis/Orion program to me
They aren't ; I acknowledge their authority in such matters, and if I were writing a peer-reviewed scientific paper, as opposed to a random post on a fan web site, I'd be using the official terminology. Since we're friends discussing scientific development, I'm using the SF names because I find them more evocative.
And if it's all the same , I'm going to henceforth bow out of arguments over names in this thread.

Re: Sell the SLS/Artemis/Orion program to me
About Luna and Sol, they are quite correct names for Moon and Sun, only in Latin, also they are the names of Roman gods for those celestial bodies. To be honest as far as I'm concern Moon and Sun are incorrect as for me It always were Księżyc and Słońce : P

Re: Sell the SLS/Artemis/Orion program to me
Names are just conventions. So long as both parties know what is being referred to, the rest doesn't much matter. Memorizing the names of the IAU officials seems...wildly irrelevant. Who cares?
Call it the Moon, call it Luna, either's good for the purpose of conversation.
Quibbling over the words seems less interesting than discussing designs for orbital stations to facilitate exploration and settlement of our solar system, so I'm gonna do that instead.
Even if it is not capable of doing *everything*, we can do a multistage launch system. If some sort of orbit stabilization package is required to correct the orbit to not intersect earth(which seems likely), that's still a great deal less fuel burned per launch. Immense amounts of fuel are burned just getting out of our atmosphere and up to speed. Every efficiency we can add reduces the tyranny of the rocket equation.
Sadly, probably can't *both* do a maximally efficient slingshot maneuver and also hit lunar orbit for refueling for the same trip, as if memory serves, slingshots are more effective the closer one gets to the body one's orbiting.
I agree that we're likely to need some stabilization/course adjustment package. It isn't even just for the math, you can get a certain degree of inaccuracy thanks to atmosphere. On the way out of the earth, there's going to be turbulence, winds, etc. Even the best weather prediction is inherently imprecise on that scale. You could have the orbital math down perfect, but if winds start shifting during launch, the resulting deviation ends up being pretty decent over enough distance.
If we get standardized resupply packages down to a relatively modest lift cost, that's huge. A lot of the ISS's money is continually burned on just resupply of essentials. Fuel for maintaining altitude, food, water, gasses. Yeah, we try to recycle as much as we can to minimize that burn, but if you can optimize that resupply issue, a lot of problems become a lot more manageable. Maybe we can actually get a station that utilizes centrifugal force to simulate gravity to a decent approximation. That, plus being able to lift sufficient shielding, overcomes two very large obstacles to human habitation of space.
We'll still need rockets for humans, specialized cargo, and so on, but paying rocket prices just to lift water into orbit is brutally limiting.

Re: Sell the SLS/Artemis/Orion program to me
If you don't know anyone in the IAU, it's probably safe to say you're not very familiar with how they do things, and thus complaints about how they do things are likely based on either blind conjecture or questionable third party sources. It's a quick and dirty question to gauge a probable degree of familiarity.
For example, I have issues with a number of people in organization X. I haven't "memorized" any names so much as I know who the people involved are and what their operations are like. If I didn't, then my complaints with org X would probably be easily dismissable as I'd have no idea what I was actually talking about.
I did not think this was a point of confusion when I tossed it out, but I was being rather flippant about it, so I may have been wrong.Last edited by Peelee; 2022-04-20 at 04:16 PM.

Re: Sell the SLS/Artemis/Orion program to me
It is hardly a matter of confusion. It is a point of pedantry.
I don't care in the slightest what the IAU considers the official term, or how they arrive at that determination. If someone says Luna, and I understand they mean the big rock orbiting the Earth, the individual work habits of a number of officials provides nothing to that conversation.
Use the official term. Use another term. English has quite a few terms, so long as you can make yourself understood, talk how you will.

Re: Sell the SLS/Artemis/Orion program to me
It's not pedantry, though. It's a proper name. You can say my ancestral home is Österreich, but I'd ask why you are speaking German, because in English it's Austria. You could call my friend Jorge "George", but his name is still Jorge, not George. Proper names are fun like that.
You can call it Luna all you like, but someone asking "why you speaking Italian" shouldnt come as a surprise if you do. Just as you may not care that everyone calls it Austria here and you insist on calling it Österreich doesnt mean anyone is being pedantic when they point out you're suddenly speaking German.
What you're describing is called "linguistic descriptivism", and hey, I wonder if anybody said anything about that a week ago?

Re: Sell the SLS/Artemis/Orion program to me
Prior to 2017, the SLS existed for one reason- to keep shuttle technicians employed.
Problem is, they're technicians, not engineers- Noone in the shuttle job set had actually built (let alone designed) a launch vehicle since Endeavor.

Re: Sell the SLS/Artemis/Orion program to me
If you have linguistic standards that you wish to impose on everyone else, yeah, that's pretty far into pedantry.
But if pedantry is what you're after, hey. Luna isn't specific to the Italian language. Luna is the Latin term for Moon, and is thus used as a term for it by a whole bunch of languages with Latin roots. Italian, Spanish, French, Portuguese, Romanian, etc. And heck, English takes a very larcenous approach to such words. We crib words from these languages basically all the time, and English would be nearly unrecognizable without them.
It's akin to using the term Sol to describe the sun. It is easily recognized by almost everyone and has a long history of usage.
As for your insistence on prescriptivism, what authority does the IAU have over language? I didn't elect them. They don't have a divine right to rule. They didn't conquer us. I'm not employed by them. There is no justification for it to have authority over language. The IAU gets to use whatever terms it wants for itself, but it has exactly no power over anyone here, nor does it control language.
Hell, what'd we call the craft we put on the moon? The Lunar Module, yes?
If I were a prescriptivist, I'd probably put "lunar" into an English dictionary(Oxford, in this case), and see what came up.
of, determined by, or resembling the moon.
"a lunar landscape"
So, if you're insistent on derailing the conversation into linguistic quibbling, look, we have a clearly applicable definition from an authority on the English Language. I shall continue using this term, and if you have further complaints about it, please direct them to the authors of all English encyclopedias.

Re: Sell the SLS/Artemis/Orion program to me
Project Orion was a pre-NASA plan for nuclear propulsion.
The current Orion program is the NASA project to build a deep-space rated reentry capsule designed to be launched on the Ares 1 rocket and docked with secondary components launched on the Ares 5 unmanned heavy cargo rocket. The Ares 1 and Ares 5 have both been long been canceled, but the Orion Capsule lives on as an overweight, underperforming -standalone- moon return capsule launched on the SLS rocket. It has been selected for use in the Artemis program to return to the moon, and all the other components of the system have to accommodate Orion's shortcomings for being forced into this solo role.

Re: Sell the SLS/Artemis/Orion program to me
It is difficult to understand when it is presented as the actual name (ie not a nickname). And even then, instead of simply "I know it's not the name but I think it sounds prettier", which is a reply I had no problem understanding and accepting on this very forum, when one says "well I don't care," then yes, it's even more difficult to understand or accept. If someone calls my friend Jorge "George" because they don't care that his name is Jorge, I'm not going to assume it's a nickname. I'm going to assume things of the person blithely calling him "George".

Re: Sell the SLS/Artemis/Orion program to me
The moon is not a person, unlike Peelee*. Geographic locations often have many names. In some countries which name you use for a region is politically sensitive and reflect territorial claims. There are also geographic names upon which political names are superimposed , and both are correct within their context. "Great Britain" , for example, is the proper name of the big island off the coast of France. But it's not the country. The country is the "United Kingdom". A geographic name and a political name, both of which are accurate. "Turkey" is a political entity which exists upon "Asia Minor", a geographic location. Likewise , 'America' is the geographic name for a pair of continents on the planet, but that's not the name of any political unit. There are more than twenty countries on those continents, none of which are named "America". There is a "United States of America", and its citizens are often called Americans for short, but that's not strictly speaking accurate. Guatemalans, Argentinians, Canadians, Uruguayans, Brazilians, are all "Americans" too, at least in the sense of inhabiting the same continent.
The Moon is a planetary body. It has many names in many cultures , and all of those names remain valid for the big rock in our sky. There is one specific name that is used by the IAU for international scientific discussion, and within that context is the only proper name to use. However, we do not insist that there is One True Name for this geographic objects in all contexts, and we are not in an international scientific context here on this board. This is a fan board for a web comic, which includes a number of sci-fi geeks, among which I number myself. "Luna" has been a name in the SF community for the moon for at least 7 decades, and I contend for its validity within that context.
I will continue to hold this position until the moon manages to anthromorphically personify itself and demand to be called some other name such as Selene. If human colonists create a nation on the moon and call it, say, the Republic of MoldyCheese, then that part of the moon will be called MoldyCheese and its inhabitants MoldyCheesians, but the geographic name would still be The Moon.
A person has the right to a proper name , and it is respect to call them by the names they give themselves. The moon has no name, however, save those what bands of humans have given to it. Until the moon objects, I see no reason not to continue to use the name I have given it, since it is well understood in the community I am speaking to.
Respectfully,
Brian P.
* Technically speaking, there's no reason a human can't have more than one proper name. "Mithrandir among the Elves, Tharkűn to the Dwarves; Olórin I was in my youth in the West that is forgotten, in the South Incánus, in the North Gandalf; to the East I go not. "
As you recognize in the books, the wizard of many names is referred to as both Mithrandir by Legolas and as Gandalf by Frodo, but he doesn't take offense at either name. Neither name, in fact, is the name he came into this world with. They are names he was given by the peoples he visited, and he accepted them graciously.
For that matter, in the real world and in mythical worlds religious and occultic groups often give a craft name or a secret name upon initiation in addition to the name given at birth. Those within such groups will refer to each other by those names within that specific context but never use them in front of outsiders.
Now that I think of it, we all have different names on this very board. I'm pretty sure that "Tyndmyr" and "Lord Torath" are not the names on their birth certificates. They are board names chosen for use on this board , not valid outside of this particular context.
So many humans have multiple names for many reasons. Board names, craft names, names given at marriage .. how boring it must be to have only one name! -- BDP."Every lie we tell incurs a debt to the truth. Sooner or later, that debt is paid."

Re: Sell the SLS/Artemis/Orion program to me
Indeed, and as I mentioned yesterday, if you were to ask about my citizenship for Österreich, I'd ask why you're suddenly speaking German because we call it Austria. Just like how I don't say Estados Unidos, despite that being a perfectly valid name for the United States. Because that's the name in Spanish.
Those, of course, are still close either phonetically or by strict translation, so if you want something differential, we could always go to Germany/Deutchsland.

Re: Sell the SLS/Artemis/Orion program to me
If the moon is offended and comes to me to talk about it, I'll apologize and use the name it prefers.
This is a good summary.
SpaceX is pretty much the only other game in town playing on this level. They've got a launch schedule that is getting pretty darned intense, even if single launches are not as large as some other options. That matters, since sometimes you do want to lift one really big object for whatever reason, but sometimes you can divvy stuff up. Just depends. For stuff like Starlink, SpaceX works extremely well, and they'd likely be a very good resupply option.
Having more than one option on tap isn't a bad thing, too. That way if one launch system is grounded for whatever reason, you've got alternatives. This came up relatively recently when world events threatened the usual ISS resupply schedule. Having a backup plan is great when supporting lives on a station is a possible consideration.
What you see as the role of humans in space ends up being a big factor in what development you hope to see happen. If you just want the occasional robotic exploration mission and earth sats, well....we don't really need to develop much at all. But if you're hoping to see us colonize the solar system, then even these plans would be just the start.

Re: Sell the SLS/Artemis/Orion program to me
SpaceX is not the only other game in town. The People's Republic of China has a very robust lunar exploration program. The program is named "Chang'e" after the moon goddess. They have landed probes and even returned samples from the moon. They have planned launches for 2024 to send unmanned probes with rovers and maybe a flying drone to explore the south pole for resources and bring back samples. They plan on a manned mission around 2030 and claim to be developing their own super heavy lift rocket, Long March 9, that is at least as capable as Starship or SLS.
Maybe some day in the future we will not be using "Moon" or "Luna". We will be calling our satellite "Chang'e".

Re: Sell the SLS/Artemis/Orion program to me
Thus the "playing on this level." China and India are playing catch up with stuff we did many decades ago, the EU has a launch tempo that's pretty light(their historical launch data doesn't list anything after 2020), Blue Origin is a tourist thing.
There's a lot of programs out there, but SpaceX and the US gov are way ahead of the rest of these. The Starlink sats they've launched alone account for over a third of mankind's satellite cluster, and the US gov makes up most of the rest. They're the huge players in the market.

Re: Sell the SLS/Artemis/Orion program to me
It's a lot more complicated than that though. The (adjective?) is lunar. In English you would never say Moonar or Moonlar craters, it would be lunar craters or craters on or of the moon. Similarly with The Sun and solar.
https://en.wikipedia.org/wiki/Lunar_craters
https://en.wikipedia.org/wiki/Solar_flare
With some of the planets (and Pluto) it's simply the name and ~"ian"
Venusian, Martian, Saturnian? Uranian, Neptunian, Plutonian.
Others, not so much: Mercurial? Terrestrial, Jovain, and sometimes I've seen or heard Venerian for "relating to Venus". Solar for "of the sun" and Lunar for "of the moon" fit right in with these.Last edited by halfeye; 2022-04-28 at 10:42 AM.

Re: Sell the SLS/Artemis/Orion program to me
How many probes has SpaceX sent to the moon and returned samples? How many probes to L1? Or to Mars? China is currently building a space station. The core module went up last year. Two more modules are going up this year. In 2021, China launched more rockets than the US, and that includes all US launch providers, not just SpaceX.
I am always surprised by how little western observers know about China's space program. I don't know if its a matter of national pride or people sticking their head in the sand but China is passing us, in particular when you look at Lunar Exploration.

Re: Sell the SLS/Artemis/Orion program to me
The US has an active Space Station, the ISS. The US sent humans to the moon decades ago (and acquired a quite large collection of samples doing so, 382 kg of moon rocks were retrieved by the Apollo missions). The US currently has two probes active on Mars to China's one.
China's space program is advancing, fairly rapidly, and the government-backed United States' has been fairly stagnant for some time, for political reasons, but China's achievements in space should not be overstated. The fact that China has more Lunar-center activity right now is not particularly relevant to anything. Space exploration unfolds on a scale of decades.

Re: Sell the SLS/Artemis/Orion program to me
Zero, that's not their business model. That said, India has done two moon missions, so if that's your metric of success, it's oddly specific and will result in some strange results.
Though there is a passenger trip to the moon slated for next year on SpaceX's launch schedule. I believe it's already full, so if you want a ticket for a moon flyby, you'll have to wait for a future launch.
SpaceX first launched a probe to L1 in 2015.
Or to Mars?
China is currently building a space station.
SpaceX has run 31 missions to the ISS.
In 2021, China launched more rockets than the US, and that includes all US launch providers, not just SpaceX.
Well, I guess you can count the failed launches, if you want. That adds several to their numbers, but SpaceX didn't have any of those.
That isn't really a point in China's favor, though. And you're measuring the wrong thing.
SpaceX is actually doing industrial work with their launches. These are functional launches, not mere tests. Stuff like the Long March 8 is cool, but it's only a second flight, and without side boosters at that, greatly limiting capacity. Most of the Chinese launches are Long March 2/3s.
LM 2s get less than 10k lbs to LEO, while the Falcon 9 that SpaceX uses as it's standard platform puts over 50k lbs to the same orbit. SpaceX launched 31 of those in 2021 alone. If we start looking at SpaceX's bigger stuff, like the Falcon Heavy, we're looking at over 140k to LEO in one trip, and Starship can pull off 220k.
One Falcon 9 can put a cluster of fifty sats into different orbits and does so every couple of weeks, whereas China straight up lacks that capacity at all, and is doing like three at a time. It's like saying a Civic is as good as a semi at hauling cargo because you've driven more trips. It's...just not.Last edited by Tyndmyr; 2022-04-28 at 04:40 PM.

Re: Sell the SLS/Artemis/Orion program to me
Then you should care about the vast, vast majority of what Tyndmyr said there, because he's spot on. Two out of every three satellites in LOE belong to the United States. We easily have the most space launches globally, the ISS is primarily American and open to the numerous countries. Hell, the only reason the Chinese are making their own space station is because we won't let them play in ours.
Space is currently dominated by the United States. NASA, ESA, and the Russian Federal Space Agency are all major players in the game who also like to play well with each other.Cuthalion's art is the prettiest art of all the art. Like my avatar.

Re: Sell the SLS/Artemis/Orion program to me
I think language plays a big role. I can only comment on the Space Policy side of that. If the Chinese government has a English or German
substantial description of it's Space Policy online available I simply have not been able to find it. English sources for western space programs are easier to come by.

Re: Sell the SLS/Artemis/Orion program to me
Point of order, the international space station is not "our" space station. It is a joint venture between the US, Canada, the EU, Japan, and the Russian Federation. I know there are specifically Russian modules, built and launched by them, just as there are modules and astronauts from the other players. I know that recent world events have called the arrangement into question, with the Russians threatening to stop resupplying or transferring western astronauts to/from orbit with their Progress rockets, forcing us to rely solely on the SpaceX missions. That threat seems to have died away for the moment, perhaps because all players realize they have more to lose by such an action than to gain.
At any rate, we can't describe the ISS as a foundational achievement of the US as showing superior space capability vis-a-vis other nations such as China. The US doesn't have its own space station and hasn't since Skylab in the 1970s. If the US is the leading power in space, it is due to our ability to put things into orbit, which at this point appears to be predominantly in the hands of private organizations such as Spacex, working alongside NASA but NASA seems to be stepping back into a supervisory role, as the FAA does for air travel.
