A Eulogy for Iridium 138
Feed is running a piece written by Bruce Sterling regarding the destruction of the The Iridium Satellite system. We've also linked the folks who are trying to rescue the system, so take a gander for them as well.
Sterling's a poor journalist (Score:1)
There are NINETY Iridium satellites in orbit, the 66 active, plus spares and others. But no, only 66 satellites are going to burn up. This mantra has been repeated by every clueless journalist out there.
Accounts weren't disabled last Friday; Motorola's still running the constellation.
What Russian investment in the system proper?
'falling into our outer atmosphere like abandoned Cadillacs.' - how many abandoned Cadillacs have done that, exactly?
'in a real-life vacuum, there can be no Strauss soundtracks. In reality, there was only the near-silent radio crackle of Iridium phone calls.' - near-silent radio crackle?
Feed paid for that? /. linked to that? give me a break.

Johnson's Dictionary had only come out in the 1750's IIRC, and the very idea that there could BE a standardized spelling of English words was pretty new. Before no one had cared; it wasn't important.
But the Americans had no problems with English save for a couple of them like Webster (who was also big on dictionaries) Adams and Franklin. They briefly messed around with significant changes to English, in the hopes of creating the American language which would distinguish them culturally from England. It went over like a lead balloon.
As for changing everything to German, that was actually a proposal to help accomodate immigrants, many of whom were German at that time. It was also not recieved well.
Webster did have a significant impact on spelling through his dictionary, but by the 1820's had more or less given up the cause of creating a new language or even significantly standardizing it.
It still took a while for spellings to really become standard. Improving literacy rates helped a lot. Nowadays, no thanks to radio and tv, we're even losing regional accents. Everyone sounds like a frickin' midwesterner more and more all the time.

Having only a layman's understanding of the Apollo and Space Shuttle programs leads to the firsts as the only things that stand out: Apollo 11 and STS-1. Been There, Done That.
The general (meaning non-geek) public was told Iridium would revolutionize communications. It didn't, and now the satellites, and the money to develop and launch them, are going up in the friction-induced flames of re-entry. Compound that by the aftermath of the Mars mission snafus, and you can understand the public perception, echoed by Sterling, that space is turning out to be a letdown.
Sure, we know better. That's why we're bitching on Slashdot, not reading it in a newspaper and bitching to the room at-large.

One of the significant problems with the project was that they were trying to get them to work exaclty like cell phones - cell phones in 1989
that is. The Mot engineers hit that target right on the head. It's too bad that cell phones had moved so far away from that target that Iridium became little more than a technical curiosity.
Cell phones back then were huge- the Motorola brick phone was the most portable at a couple of pounds, about 4" deep, 3" wide and 8" tall and most of the other phones had a handset with the batteries and other stuff in a separate pack, like carrying a standard Bell 1948 Desk Phone around with you.
And they didn't work very well indoors or in a car, because the few cells that were out there didn't overlap (so you'd drop going from once cell to the next) and were often quite far apart (so you were probably at the edge of the range to begin with, and walls would block the weak signal).
Though the Iridium phone I had worked while in the car, the window needed to be down and the antenna needed to be stuck out the window and pointing up (it had a joint so you could hold it normally and still point the broomstick sized antenna up). That made it pretty hard to hear, as you can imagine. They had external car antennas that you'd plug into the phone that apparently made using them in the car a lot easier, but I didn't get one of those (I wasn't paying for it, so I got what they gave me).

A great deal of that expense is tied up in just being the shuttle; i.e. a monopolistic government run program that is a sad example of what goes wrong when designing by committee (but that's another rant).

Actually, there are some possibilities; deuterium and tritium may be available in (relatively) high concentrations on Mars and are worth more, gram for gram, than just about any precious metal/gemstone. There are other commercial possibilities that people have been pondering on for years; G. Harry Stine wrote The Third Industrial Revolution back in the late 70's, and more recently, Robert Zubrin answered a lot of "why bother?" questions in Entering Space. So, while mining might not be enough to get commercial space exploration going, there are other possibilities. The biggest trick now is to get NASA to facilitate commercial ventures instead of obstructing (yet another rant).

In the 50's and 60's, transistors were the thing to the average consumer. Imagine, a device that could replace bulky vacuum tubes, yet was smaller, cheaper and had a much lower power consumption. Why, you could build an AM radio that would fit in the palm of your hand! The idea of integrated circuits was around, but not considered necassary for any consumer electronics. Then along came NASA and the Apollo program, trying to fit more and more control and monitoring systems in a smaller space. Five years later, consumers had access to hand-held calculators. Five or ten years after that, consumers could buy their own home computers. From there, computers snowballed, driven by market pressures instead of Federal whim and now we have Jar Jar Binks and Palm VII's and the internet and so on... So those "uncool" rockets that Sterling slams are directly responsible for his royalties.
From a financial and even technological perspective, Iridium may have been a major failure, but his Luddite attitude is unwarrented.

OK, so I guess Bruce Sterling feels the need to declare rockets and space as "uncool" on behalf of computer geeks everywhere, and some who want other people to do their thinking for them have taken them up on the offer.
Still, in spite of the fact that he's picked Iridium as proof of the end of the space age, nevertheless, GEO comsat use is booming, and terrestrial cellphone use, when you're not in a major metropolitan area, still sucks.
However, just because an implementation of an idea is bad doesn't necessarily mean the idea is bad in and of itself. The Great Eastern was declared one of the biggest boondoggles in history at the time; however, after that it proved to be very useful in laying the first transatlantic cable. (Which was done by Lord Kelvin, and was one of the reasons he became Lord Kelvin. (Apropos to this discussion, he once said there was no future in heavier-than-air flight, and that X-rays were a hoax.)

They were way too damn expensive. The calls, (when I was assigned to evaluate the service) was something on the order of $6 US (plus long distance). Which really came down to about 8-10 dollars a minute. That was down by more than half from when they first announced the service. The phones themselves had come down quite a bit and were about comparable to some of the more expensive cell phones. There were units in the thousand plus range, but most of the Kyrocea line were around $250-500 us.
The phone, while big and bulky, wasn't too bad in size. The voice quality was pretty good, not great, it was essentially cell phone quality. It was hard to aquire a signal lock when inside, but out in the clear it worked like a phone. It didn't work too well in a car, but an external antenna would have helped, and cell phones don't work too well in my car either.
The system worked. But it cost too damn much. Nobody rich enough to afford them was going to buy them because they didn't get that rich by blowing $500/hour on phone calls. Nobody else could afford them. They were so expensive the only justification I could come up with for using one was for calls that go something like "I'm in the jungle and a blue, red, and green snake just bit me, what do I do?" Had they been cheaper, I could easily see calls like "I'm in the jungle and it's beautiful here, I wish you could see it!"
There's a price point there somewhere, and I'm betting it's somewhere around twice what people would pay for a cell phone, not 15 times. Then people would be able to buy them when they were doing things where cell coverage is questionable, not just totally unavailable.
Lowering the cost of launch services is the key to getting costs low enough to reach this price point. Reusable launch vehicles are the way to do this. The problem is, too many people are making too much money throwing away perfectly good rockets to bother coming up with a cheaper, more effective way.

But that shouldn't distract from the enormous potentialities of space exploitation, and mass expansion of humanity beyond this planet. Don't forget that 1000 years ago the first Europeans came to America, but apparently technological and economic improvements were needed to make it more directly feasible; even after Columbus arrived it took another 120 or so years before U.S. history really began. Now some people cross that once fearsome ocean on a daily basis.
There are a huge number of proposals out there for more efficient ways of getting into space, for living off the "land" there, etc. Currently the Mars projects are the most enthusiastically supported, and are now actually practical. New types of rockets with new materials and designs, non-rocket designs (electromagnetic launching) and even the skyhook/space elevator approaches are making a mass exodus into space look more and more feasible. 500 years from now Stirling's goal could be more than achieved, as Earth can become a galactic park, free of its human burden.

(1) Racal uses provides real time differential correction of GPS signals for surveying. And no application gets more "down to Earth" than surveying.
(2) Communications sats. Lots of 'em. Is anybody laying trans oceanic telephone cables anymore?
(3)Remote sensing and imagery. Not only are there several privte companies with their own satellites, but there are lots of small companies, including mine, which resell images and help a variety of clients make use of them.
If Sterling had accurately predicted the financial reasons for the Iridium project's demise five years ago, he'd have reason to act self-satisified, but as far as I know he didn't. His analysis is as valuable as predicting yesterday's horse races.
The failure of GSM (Score:2)
My PCS phone died an ignomious death a few months ago, so I looked into alternative replacements. I had really wanted to get a GSM phone, but America hasn't gotten on the GSM bandwagon. There are only a few carriers (Omnipoint being the main one), and those are mostly located on the East coast. No one has good national coverage.
That was a pain. Then, although you can get tri-band GSM phones that work in the U.S., Europe, or most of Asia with just a change of SIM card; these GSM phones don't work in Japan!
Seems the brilliant bureacrats in Japan pulled off an American Not-Invented-Here trick with the frequencies, so even tri-bands don't work. Argh!
I just want a phone I can use anywhere in the world. GSM is so, so close. But until more poles are erected in the U.S. and Japan gets with the program (or phones emerge that can handle the Japanese frequencies), it looks like I'm SOL.
So I bought another Sprint PCS dual band phone.

ps. for the person bit by the snake in the middle of Congoland, there's still INMARSAT. Prices are cheaper than Iridium, although you do have to lug a suitcase rather than a portable phone. Does make you look considerably more geeky and james bondy though!
pps. I heard one of the problems with Iridium is that unlike Inmarsat, which looks like a satellite phone with the briefcase and dish antenna that you have to point in the right direction, Iridium phones looked like cell phones (albeit with big antennas).
But that gave people the idea that if they looked like cell phones, surely they must work like cell phones. So they tried to use them in conditions they weren't designed for: namely indoors and in moving vehicles. Their performance expectations (of cell-phone like stability, whatever that is) weren't lived up to and Iridium got bad press. This was especially true in the Bosnian conflict, when a lot of Iridium phones were seeded to the press. Many of them abandoned Iridium and used their GSM phones instead.

It'd be odd to "guess rightly" that they have "plenty of bandwidth" when the backers claim that the lack of bandwidth was what made the system not worth keeping up. I'm curious exactly what the bandwidth characteristics of the satellites were.
And the ramifications if bandwidth was limiting or ping was the deal-killer are rather relevant. One implies that no satellite system at that height or higher would *ever* make sense for Internet access, the other implies simply that a properly designed system might be feasible.

Much more upsetting is the radio interference. Motorola promised and promised and repeated their promises throughout all phases of the project, that their amplifiers were nearly perfectly linear, and would not cause interference in sidebands. An adjacent sideband is used by radio astronomers to observe OH radicals in molecular clouds.
When the first satellites went up, the ugly truth was revealed. The amps were NOT "nearly perfectly linear" after all, and leaked significant interference into adjacent bands, including the OH band. This threatened at one time to basically put an end to observation of the OH band altogether. Negotiations with Motorola and appeals by the IAU managed to get Iridium's signals curtailed or eliminated during certain times of day over important radio observatories. Because of Motorola's false promises, and the resulting limitations they were forced to accept, Iridium could never have fulfilled its potential anyway; at certain times of day, near certain regions all over the world, the satellites were simply out of service. Also, in the meantime, advances in signal processing allowed radio astronomers to better filter Iridum's interference. If Iridium had continued to operate, radio astronomy would have been able to adapt to most of the interference, and conduct observations. On the other hand, the presense of Iridum underscored the value of a radio observatory on the far side of the moon. A side effect of Iridium's demise is that this need is not as pressing - for now.
In any case, good riddance. I will enjoy watching them fall into the ocean.
Globalstar might have a chance (Score:3)
Globalstar has a few things going for it. It's a much simpler technical challenge since the satellites themselves are relatively simple "bent pipe" repeaters unlike Iridium which had a lot of cross links (think cell sites in the sky, not routers in the sky). Per minute charges are usually cheaper and their regulatory battles have been easier because they use the public telephone network for most of the journey of the call. The handsets switch to CDMA/AMPS/Globalstar or GSM/Globalstar as appropriate so they are usable within urban areas.
In addition, Globalstar has made a big push for fixed installations, such as a payphone in a remote village. This is a huge market which is underserved and overpriced currently.
This doesn't mean they can't or won't fail.

As much as I like Bruce Stirling for all his nifty science fiction, a quote like "when people realized that the Moon is much less interesting than NASA said it was" simply sucks.
I don't know where you were, Bruce, but I know that I and a whole bunch of other folks never found the moon "much less interesting." You might have been busy having your diapers changed, but I was in the middle of a college career based on astronomy done with orbital observatories, and when Congress cancelled all the programs, my dreams died along with a lot of other people's. It wasn't lack of public interest, but lack of the Cold War push -- simple science wasn't worth it, while military superiority was...
Despite this sort of whining, the space program hasn't gone away -- there are still quite a few people who work in it, myself occasionally included. And while there are still mismanaged (and ill-conceived) programs like Iridium, the dream is not yet gone. We just hacked our way back into it.
Look back in a hundred years, and no one will understand why we didn't do it faster -- after all, we had the technology, all we lacked was the will.

Before chasing the unfeasible (like S.O.S)., look into AMSAT [amsat.org] These guys have a real amateur satellite system (over 30 satellites, 20 currently operational) going back 30+ years. Their satellites are 'open source' public designs, garage built (none rejected for failing clean room standards) by volunteers and launched by international cooperation in exchange for their collaboration and expertise. They pioneered some techniques used on commercial satellites today!
Consider contributing your efforts here. This is Linux in space, but with a heck of a track record!
They are a 501(3)(c) certified not-for-profit, so Iridium could conceivably be donated with full tax benefits (if any). And it they decide Iridium is unsalvageable, then you can be sure that it truly is. They have the volunteer/hacker base of regulatory and technical know-how and experience that most of us obviously didn't believe existed.
Iridium or not, doesn't his sound like a group you want to join? (I'm currently working on the details of a proposal to test modern era CPUs in space. Most current space-certified CPUs are ancient - pre286)
(from the web page http://amsat.org/amsat/amsat-na/amhist.html)
The Radio Amateur Satellite Corporation (as AMSAT is officially known) was formed in 1969 as a not-for-profit, 501(c)(3) educational organization chartered in the District of Columbia. Its aim is to foster Amateur Radio's participation in space research and communication. Since that time, other like-minded groups throughout the world have formed to pursue the same goals. Many of these groups share the "AMSAT" name. While the affiliations between the various groups are not formal, they do cooperate very closely with one another. For example, international teams of AMSAT volunteers are often formed to help build each other's space hardware, or to help launch and control each other's satellites.
Since the very first OSCAR satellites (OSCAR stands for Orbiting Satellite Carrying Amateur Radio) were launched in the early 1960s, AMSAT's international volunteers, often working quite literally in their basements and garages, have pioneered a wide variety of new communications technologies that are now taken for granted in the world's satellite marketplace. These breakthroughs have included some of the very first satellite voice transponders as well as highly advanced digital "store-and-forward" messaging transponder techniques. All of these accomplishments have been achieved through close cooperation with international space agencies which often have provided launch opportunities at significantly reduced costs in return for AMSAT's technical assistance in developing new ways to launch paying customers. Spacecraft design, development and construction has also occurred in a fiscal environment of individual AMSAT member donations, thousands of hours of volunteer effort, and the creative use of leftover materials donated from aerospace industries worldwide.

Bye, Bye, Miss Iridium Pie
By [snip]
Sung to the tune of:
Bye, Bye Miss American Pie, by Don McClean
Long, long time ago I can still remember how the funding made me smile
And I knew if we had our time that we could make that payload shine,
And maybe make the launch occur on time
But '95 made me shiver with every build that we'd deliver
Bad news in the high bay, I couldn't go one more day.
I can't remember if I sighed when I read how the lawyers lied
Something touched me deep inside the day the funding died.
So bye bye Miss Iridium pie, spent our millions and our billions but we made them fly
Them good old days have now gone by
Knowing this'll be the day that it dies
This'll be the day that it dies.
Did you write the specs we love and do you have faith in the ones above?
And did you like the shirts we wore, did you believe in the 3 oh 4?
Well I knew the facts and I spoke to Jim, cause I was standing right next to him
They both kicked down the rack and then ran away out back.
I was a lonely old software hack with a stack of cards and a line of jack
But I knew I was on my back the day the funding died.
I started singing:
Bye bye Miss Iridium pie; spent our millions and our billions but we made them fly
Them good old boards are way up high
Knowing this'll be the day that they die
This'll be the day that they die.
Well 10 years have now gone by since the gleam got in Bary's eye
But that's not what was to be.
When investors sang in the court of law in a place where truth brings on awe
In a voice that sounds like Craig McCaw.
And while the team was looking down
The lawyers stole what we had found; the courtroom was adjourned
Bankruptcy was returned!
And while the judge read a book on sharks, the lawyers danced in the park
And we sang dirges in the dark the day the funding died.
We started singing:
Bye bye Miss Iridium pie; spent our millions and our billions but we made them fly
Some good old boys paid seventy five
But this'll be the day that it dies
This'll be the day that it dies.
Helter Skelter in the summer swelter the cows pies smell and we seek shelter,
Our cubicles are all in a row, and we go in and pray for snow.
But we know not how it might go
Hacker lined up 20 deep. They try to code but need the sleep.
We all lay down to snooze, but then someone breaks out the booze.
Pizza comes and we go wild, the peppers fly 'cause it too mild.
Do you recall what was the deal the day the funding died?
We started humming:
Bye bye Miss Iridium pie; spent our millions and our billions but we made them fly
Them good old rockets reached the sky
But this'll be the day that it dies
This'll be the day that it dies.
In there we were all in one place trying hard to get in space
With no time left to start again.
So all be nimble, all be quick, the build is due or we'll be sick
'Cause coding is the devil's only due
And as I watched the rocket flare, all eyes left had turned to stare,
Bloodshot, tired , and burned to hell.
Smiling sweet in the fiery swell, flames climbed high into the sky and we all clapped 'till I thought
we'd cry
Before the funding died. We started singing:
Bye bye Miss Iridium pie; spent our millions and our billions but we made them fly
Them good old days are now gone by
And this'll be the day that it dies
This'll be the day that it dies
I met a man who had the "sight:" I asked him if the program might...
But he just smiled and turned away.
I went down to the big high bay where I'd seen the payloads years before,
But the man there said the payloads wouldn't play.
In the halls the techies sighed, the coders laughed, and the testers cried,
Not a word was spoken, the stations all were broken.
And the three things I admire most: beer, cheese, and hot french toast,
I'll be eating out on the coast, the day the funding dies:
And I'll be singing:
Bye bye Miss Iridium pie; spent our millions and our billions but we made them fly
Those crosslinks work but we don't know why
And this'll be the day that it dies
This'll be the day that it dies

At the time that Iridium was being designed and implemented, GSM was taking off. Who cares if their phone doen't work in the Rub Al Khali? It works in Boston/Manchester/Kyoto. Very few rich people live in serious wilderness. Those that do can make their own arrangements.
With satellites, you make a trade-off between the number, the altitude and the latency. For useable voice, you *must* have low altidude satellites."Do not exceed the speed of light. It's the law." That has two immediate consequences. You'll need a lot, and they won't last long. The upper atmosphere will eventually cause the final 'Iridium flash'.
Which moves us on to the vandalism of Iridium. The antennae on the sattelites are *incredibly* flat polished surfaces pointing at Earth. So they reflect sunlight *very* effectively. This upsets astronomers. The reflected sunlight flash from an Iridium satellite can do a lot of damage to an astronomical observation.
Then, the choice of frequency for transmissions. Slap bang in the middle of a *critically* important astronomical region. I may be wrong, but I think it's a CO band.
I'm sure this will be said again, but cutting the number of satellites must have irked the gods. It's called Iridium because the number of satellites that they were going to launch was the same as the atomic number of iridium. Then they scaled it down the the atomic number of dysoprasium. My Greek is bad, by dysopraxis is 'inability to speak'. Bad decision.
