"Approximately 19,000 objects larger than 10 cm are known to exist. The estimated population of particles between 1 and 10 cm in diameter is approximately 500,000. The number of particles smaller than 1 cm probably exceeds tens of millions."It might take more cleanup launches than it took original launches to remove this stuff. That's more than 5,000 launches! That's more than two per week for 50 years! Sounds killer to me. - Ed Kyle
So how to foster the low end of the market?
Now suppose the rockets do start showing up one a day, and departing on schedule with a success rate that makes the supplier's profit margin juicy enough to fund further R&D, but the payloads don't appear. The Agency rapidly becomes the butt of every stand-up comic and a motion is introduced in the Legislature to re-name it the “Orbital Ready-Mix Delivery Agency”. Well, if that's how it plays out, I guess we all ought to pack up and go home then, shouldn't we? Because that would demonstrate, in a real-world test, that there really aren't very many useful things to do in space, after all.

Sounds killer to me. - Ed KyleThis is really a very good example of the worst killer-app at all and thus very educative:First of all, 5000 Launches in 50 years is mere 100 a year. Currently, about 60 to 70 orbital rockets are launched per year. So increasing launch rate by two point five is not really a killer-app.Second, the space-cleaning-maids (images from "spaceballs" come to mind) launched would be highly complex spacecraft themself. Their cost would be prohibitive, much more than the launchers needed. Thus this would be a massive investment in spacecraft and mission operations and in relation the cost of the launch is - well - rather unimportant. So this wouldn't exert the needed pressure on launch costs.I think the best killer-app is the ISS and successors (both, gov and com) in terms of their resupply, lots of launches with rather low-cost payloads (food, water, propellant).
QuoteSo, what "high volume" payload can I imagine? Space junk mitigation! Space junk is increasing, even if no more satellite launches were to take place. Removing that junk is going to be a long, hard job. It could involve thousands of launches. - Ed KyleEveryone is always looking for a "killer app" that needs lots of launches. I don't think you've found it, yet. Unless, of course, there's a war which destroys a good portion of the satellites already in orbit. Not exactly a rosy scenario, though.Still looking for that killer app.

Quote from: Blackjax on 02/13/2012 04:31 pmSo how to foster the low end of the market? Like this.Launch slabs of concrete until an application shows up. If it does not in a few years ( and better have the funding to keep launching daily for a few years ) it was a dead cause.
Where do you think the funding would come from for this?
Quote from: Blackjax on 02/13/2012 10:22 pmWhere do you think the funding would come from for this? A measly $500M - $1B a year to open up launch market ? I know a few certain boondoggles that i would take it from in a heartbeat, but yeah it's not my money.Where would the funding come for any of the stuff in this thread by the way ?

The flaw in most plans that are debated here is where does the money come from? It is all well and good talk about Zubrins plans, or big exploration projects you'd like SpaceX to spend money on, or NASA programs that would 'thousands of launches' but is anything like any of those really gonna get funding? If it gets funding will it be consistently funded over the length of time needed to achieve its goals? A sustainable industry doesn't rely on a single killer app funded by massive doses of money which nobody is likely to pony up, it will happen by ramping up on a variety of fronts. A miracle giant project might fall in our laps and gift us with a vibrant industry, but I don't think we should be banking on it and in the meantime look for ways to bootstrap in more mundane and modest ways.NASA might get funding for a debris mitigation project, and that might contribute some payloads to the launch market, but it is pretty likely to be a modest project with a handful of payloads not one with thousands.SpaceX might invest in things which help grow their market but I don't think it would involve large volumes of launches on their own dime NASA style, it'd be small investments and/or things they can get things like tax deductions for.Zubrins plans? Not even gonna go there.So again, the question is how can you grow the market based on approaches which don't require epic amounts of money with no obvious likely source?
You seem to forget that the payload guy are investing heavily on the technologies for making "fewer" launches. We are seeing satellites with hundreds of transponders and Gbps of bandwidth. The orbital slots are basically all taken. There's a glut of commercial imagery. And let's not forget that fiber optics and wireless technologies also compete. So basically you have a lot of effort on making less launches.And it's not because the launch cost is high. Is because a mission life cost and risk is huge. So it gos to a single huge and expensive launch.
...a 1cm square thruster that includes a layer of solid state sodium azide. When a picosatellite needs to make a position adjustment while in orbit, a circuit underneath the sodium azide will heat to 275°C, at which point the chemical releases a burst of nitrogen gas enough to execute a maneuver. By covering a picosatellite with these simple thrusters, the satellite can make numerous controlled position adjustments throughout its lifecycle. Miniaturized satellites are a trending topic for university and independent researchers finally able to reach outer space without reaching into incredibly deep pockets. Incorporating the latest developments in micro-circuitry, revolutionary propellants, and even off-the-shelf consumer electronics, these devices can be fabricated and launched for a fraction of the cost of a traditional satellite.
"Because it’s so expensive to launch, we want the satellites to live very long, so by the time you reach end of life of the satellite on orbit, your sensor and computing technology can be anywhere from 20-30 years old. And with Moore’s law operating on computing technology, that’s a good 15 to 20 generations out of date. Cheaper launch would open up design trades that could allow more frequent tech refresh on orbit, which would create demand for more launches…you see the circle here. This is a cycle we could take advantage of."
. More frequent tech refreshes of satellite constellations would mean more services that could be offered on the market to consumers.
The ideas I put forward ... still require money in order to happen. So where does the funding come from? Well the benefit of a grassroots effort ... is that it does not require a single group to sell a single vision in order to achieve a huge do or die funding level. It is about generating a huge number of small efforts ... overall generating an aggregate demand for goods and services. So where do lots of small amounts of funding come from? Well, there are the traditional sources ... Fortunately there are a host of new ways to get funding for small projects:
Has Zubrin sent anything into space in the last 30 years?

Relaying data is the only service that is out there that is commercially viable. That's true if you choose to broadly define 'data relay' and lump a lot of things that appear to end customers as very different services under it. Nonetheless it does not invalidate the point I was making. The types of data relayed and the services that data support manifests in a lot of different markets, each of which might benefit some of the providers in those markets if they could enhance the portfolio of services they offer. A quick search turned up several examples pretty easily:http://www.satimagingcorp.com/services.htmlhttp://www.siriusxm.com/http://www.dish.com/http://www.directv.com/DTVAPP/index.jsphttp://www.findmespot.com/en/http://www.mtnsat.com/If there was a complete list of everyone making use of 'data relay' capabilities out there, would there be a significant subset of them who would expand in some direction they see a market in if there were the ability to get satellites up there to support it for a reasonable price? I think it is at least plausible.

Fortunately there are a host of new ways to get funding for small projects:First, I'm a little sour on the idea of grassroots movements at the moment, frankly because I think a manned lunar base is the key to expanding human presence in the solar system; therefore it should be attempted first. Unfortunately, around this forum, it is an idea whose time will not come. But on another thread, an entity intending to mine Shackleton crater for ice and propellant is apparently following a crowd source funding paradigm.At first, I poo-poo'ed the idea, since the amounts needed are so large, and the amounts gotten are so small...
I really wish a lot of the aerospace talent we have out there who got all the press about being laid off over the past year

I think it is at least plausible. The long pole isn't the spacecraft, it is the ground system. Spacecraft can be launched in a few years. Setting up a ground system and getting it distributed takes much longer. Same goes for changes to the ground system.
