Nibb31 is not American, and he's talking about the international commercial market of Arianespace, ILS and co. No, I'm not acting like the US is the entire story here. I'm demonstrating *why* they got outcompeted, with the caveat that the idiot "everything will ride on Shuttle" policy decision back in the early 80's is also a factor in that. (As is Eurocentrism and fall of the Soviet Union.) It's a complicated picture with roots that run back half a century and more. And the US is part of the international market too, and changes to US launch providers *will* have international repercussions. So, don't play the Eurocentric card, because it's bull. The problem I'm having with Nibb's response has nothing to do with our nationalities and everything to do with people trying to reduce complex situations into simplified and rote answers.

But they are not mass produced, which is a bigger issue. Link to comment Share on other sites More sharing options...
Mitchz95 Posted January 25, 2016 Share Posted January 25, 2016 For what it's worth, I remember reading that SpaceX is opening a factory to mass-produce satellites that can be purchased by outside entities. If they can make that work, I imagine the cost of the satellites would go down a lot. Link to comment Share on other sites More sharing options...

The two things don't mean the same thing, not even (censored) close. Right, I stand corrected. Commercial launch services have existed for decades too. 6 hours ago, DerekL1963 said: SpaceX's growing order book, and the responses of the established launch providers say otherwise. For the first time in history there's real competition between launch providers - and the game is already very visibly changing. This is not the first time in History. Arianespace, Boeing, LM, Roskosmos have been competing for decades. But you're right, SpaceX has cut launch prices by 50%, which is a great achievement, and they are reaping the benefits at the expense of other providers. However, it's not creating a whole new economy or revolutionizing applications for space technology. I wish it would. The best we can hope for is to see a couple of these constellations getting launched, but that market only represents a boom of 20 to 50 launches, which can be absorbed over a couple of years. After that, things get back to normal. What we really need is a "killer-app" for space, a problem that can only be solved by a huge demand for spaceflight and generates revenue. Once you've got your killer app, all the economies of scale and reusability technologies will start to make sense. I just don't see that happening in the foreseeable future.

They're as mass-produced as they're going to be able to get in the GEO ring, with the limits of the slot allocation system. Mass-produced satellites have been common for schemes in other orbital regimes, and in the vast majority of cases (Iridium, Orbcomm, Globalstar, ICO, Teledesic) have led to the purveyors going bankrupt. Only O3B has found any success in this sector, and their 12 satellites per design barely qualify as mass-production. Link to comment Share on other sites More sharing options...

I guess the question really is what does space have to offer us in the near future. If someone can figure that out and create a demand for launches I think things will rapidly change.

Exactly, which is why SpaceX's market is not going to launch the mass-produced sats- even smallsats have difficulty with mass production, even though you reduce the capacity to a lot of sats. Well, darn. Anyone have any indication that LEO comsats will take off? Link to comment Share on other sites More sharing options...
StrandedonEarth Posted January 25, 2016 Share Posted January 25, 2016 Cheaper launches lowers the risk for prospecting probes. Once Planetary Resources et al find some industrially attractive minerals in accessible orbits there will be a lot of effort going into getting mining equipment on site. Imagine what finding a huge chunk of platinum would do for fuel cell technology and affordability Link to comment Share on other sites More sharing options...

It's a cubeast- sure, it's a great start, but I really doubt they would find the asteroids that they want with this thing. It's a great testbed, but you likely need something like this https://en.wikipedia.org/wiki/Near-Earth_Object_Camera to find the enough of the kind that they want. You know, the kind that can be redirected into a closer in, constant orbit to mine. I love cubesats as much as the other guy, but they are limited.

Which is still likely too small, at 15kg. It's still a cubesat. Even B612's telescope is 1500 kg, and it is designed to capture 90% of asteroids down to 140m diamenter. Of course it will likely get smaller ones too, but the ones that can be redirected are on the order of 8 m diameter or smaller. https://en.wikipedia.org/wiki/Asteroid_Redirect_Mission You really need a big, precise telescope to find those. Granted, you can just go straight to something like 3554 Amun, and use a space tug to bring material whenever the launch window opens, which is probably a better idea. In that case, it's probably better to rent a telescope to study it, or do something like a few NEO scouts,http://arc.aiaa.org/doi/abs/10.2514/6.2014-1703 and just skip the 'finding' part entirely. Of course, you would need to make money to fund it in the meantime, which is probably the only reason one would want to go the route they are going. Asteroid Mining has only taken the first step of a hike to finally mining an asteroid. Link to comment Share on other sites More sharing options...

They still have competition from fiber cables, and from things like Oorbcomm. It will not be a revolitionary increase in SpaceX's revenue. It will help, but it will be a secondary market, like LVs to OrbitalATK. Link to comment Share on other sites More sharing options...
