Laser for Satellite to Satellite Communications
heby writes: "Last night ESA successfully tested the first laser link between two satellites (SPOT 4 and Artemis). SPOT 4 is supposed to serve as a data communications relay between Artemis and the receiving station in Toulouse. The link is running at 50Mbps and the two satellites are currently orbiting at 832km and 31000km respectively.
According to ESA "The main challenge in establishing an optical link between satellites is to point a very narrow beam with extreme accuracy to illuminate the partner spacecraft flying at a speed of 7000 m/s." Way to go, ESA!"

For years now, the common American penis bird has been a staple of every American's daily diet. Whether it be penis bird sandwiches, fried penis bird, or perhaps penis bird under glass (for the rich), we all have penis bird at least once a day. Many Americans have no clue how the penis bird became so important in the pyramid of a balanced diet, so in this article I will attempt to explain its history and why it is so useful.
In the early 1870s, Francis Zefran became the first penis bird breeder in North America. He started his famous Penis Bird Ranch in Canton, OH. At the time, not much was known of the penis bird's nutritional value, but the Penis Bird Ranch changed all of that. Not only did Francis Zefran raise penis birds to sell their colorful plumes (a VERY lucrative business), he also set up the world's first research lab dedicated solely to the study of the penis bird.
The lab found many interesting things. First, it was discovered that the penis bird was actually semi-sentient. Second, the scientists found that the meat of the penis bird was high in protein, vitamin A, vitamin B, and calcium, while low in fat, cholestorol, and sodium. Never before had such a nutritious meal been had without supplement or fortification. The scientists of the lab recommended immediately that the penis bird become a part of every American's daily diet.
When the news of the penis bird's usefulness reached president Rutherford B. Hayes, he was absolutely ecstatic. You see, President Hayes owed a number of favors to Francis Zefran because as I said earlier, the penis bird plume trade was an extremely lucrative business and Mr. Zefran was important in getting RBH elected through a number of monetary gifts. President Hayes immediately asked Congress to pass what we all know today as the Hayes/Zefran Penis Bird Consumption Act.
The act did a number of things to make the penis bird a daily meal, most important of which was the requirement that for every four people in a household, one penis bird must consumed every day. Another thing the act did was create an artificial monopoly for Francis Zefran's Penis Bird Industries. The act stated that the only supplier of penis bird meat in the US would be PBI. As one would imagine, this quickly made Francis Zefran into the richest man in the world. He was soon a multi-billionaire (quadrillionaire with today's inflation). Never before had a single man seen such wealth.
Many challenges were made to the Hayes/Zefran Penis Bird Consumption Act, and several even made it the Supreme Court. It was argued that the act was unconstitutional and went against liberty itself, but once the detractors tasted delicious penis bird meat for the first time, they immediately dropped their cases and followed the law to the letter. We all know today that penis bird is the most delicious meat man has ever known, but at that time, the only meats people ate were pork and beef.
In the early 1970s, though, challenges to the act began again. Many argued that the monopoly given to Penis Bird Industries by the act was in all ways unamerican. The Supreme Court finally agreed, and in 1974, Section II of the act was struck down. This in effect opened the market to competition for all.
Today, Penis Bird Industries is almost no more. Today we have the market leader Penis Bird Meat International facing against Penissoft, a recent startup. Where will the future lead the penis bird market? Only time will tell us, but one thing is certain: penis birds are here to stay!

On my infinite quest for karma, I decided to email CmdrTaco about what it would take for me to get an account on slashdot with unlimited karma. We exchanged emails for a while, and he always told me that it would take a very special favor to get what I wanted. Finally, I told him I would do anything, without exception, for an unlimited-karma account. He told me to go to his apartment, and I would find out there what I had to do. I thought I was prepared for anything. I wasn't prepared for this.
The first thing I realized when I got off the bus was that something was very different about this part of town. There were no girls in site, but many men. A lot of them were holding hands. I soon realized that I was in the gay corner of town. My boyish young looks got a lot of stares from the people. I found the apartment, and knocked on the door. Cmdrtaco answered the door, he was in a designer pink bathrobe. The first thing that hit me when I walked in to his apartment was the smell. It was a pungent combination: the fishy smell of sex, combined with the feces smell of, well, feces.
The whole Slashdot crew was gathered around the television. They were watching some sort of anime porn involving a little boy and his male schoolteacher. They promptly turned it off when they saw me enter. CmdrTaco told me to sit on a chair that was placed in the living room. When I sat down, him and Jon Katz tied me to the chair tightly with lan-wires. CmdrTaco then walked up to me and opened his robe, and placed his testicles on my face. He said to me "These are the TACO BELLS, LICK THEM", so I did. After licking his balls for 10 minutes he placed his cock in my mouth. I could still taste the stale shit that was encrusted on it. 30 seconds later, he was done. Jon Katz was next. He walked up to me and unzipped his tight leather pants. His erect over-circumcised penis in all its 4 inches of glory was an inch from my nose. He said to me in a high pitched, flamboyantly homosexual voice, "GIVE ME THE HELL-MOUTH, BABY!" so I stuck his penis in my mouth. 45 seconds later, I had the collective semen of two slashdot editors all over my face. Next in line was CowboyNeal. He had the brilliant idea of recording the whole encounter so they could broadcast it on 'geeks in space'. He whipped out his long hairy cock and pointed to it and said in a feminine tone "When it comes to poles, everyone chooses CowboyNeal!" 5 seconds later I had the cum of 3 slashdot editors running down my neck. Next in line was Michael. He was dressed as hitler, and his pubic hair was shaved into a swastika. I didn't even have to do anything, he just blew all over my face right away. I now had the man juice of 4 slashdot editors all sticky in my hair. Then the others did their business, including some people off #slashdot, including emad. When I got home, my black shirt had a hundred white streaks on it.
I now have an account on slashdot with unlimited karma, when I'm not having gay sex, I like to moderate down posts that are already -1. Deep down, I now feel complete. I will never forget that special night I had with the slashdot editors.

I just heard some sad news on talk radio - Horror/Sci Fi writer Stephen King was found dead in his Maine home this morning. There weren't any more details. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon.

This is just plain cool. 50MBPS conenction, through space, with that kind of accurace, kinda scary how quickly science is evolving. What will 100 more years bring?
If they transmit data and later convert it to decimal, it's ust another example of a lame base being used yet again. Why not binary or hexadecimal? Why decimal? Why?

How long was the link up for... I'm wondering because one is in a fixed orbit over a single piece of land, while the other is flying around the earth once what? every 90-120 minutes?
The sheer logistics of keeping that link up would be nearly mind boggleing.... So is anybody going to try this with a spot on the planet with a bird up in the sky (satellite)?
We can finally stream porn 31000km above the Earth!
I wonder what the latency of that link is?

Anyone know what this implies in the general development for targeting software (smart bombs, etc?
fp!@@
maybe this will help out in the future for satellite imaging to stream video back to earth instead of just pictures that take hours to transmit across space. i think it would be cool to get live video from a satellite orbiting jupiter at any given moment :)
I wonder if they have to allow for signal loss caused by bits of space junk floating by...
Okay, the odds are probably pretty damn small, just a thought.
Besides, slashdot seems screwed, I'm curious to see if I can still post...

Well, this is indeed a real challenge. Some time ago we also tried to build a laserlink and succeeded with 128kbit (IrDA). The link was very stable, there was no problem accomplishing a link at around 2km. Next we tried to "upgrade" to 10baseT but sadly never found time to finish this.

Henry Jessup on ISLAM.
The leading 19th Century Middle Eastern scholar in America, Henry Jessup, decided that Islam essentially constituted "a heap of rubbish." Jessup had read the first American edition of the Koran, which was published in 1806. The editor of that edition warned readers, in the preface, that the text of the Koran offered little more than a collection of "contradictions, blasphemies, obscene speeches and ridiculous fables."
Mark Twain on ISLAM.
One of America's most popular humorists, Mark Twain, perpetuated this scholarly tradition. Although Twain earned a reputation as "the Lincoln of our literature" for his brilliant denunciation of slavery in "The Adventures of Huckleberry Finn," the author had a potential for nastiness. Eighteen years before he published Huck Finn, Twain engaged in a grand tour of the Holy Land. Twain recorded his impressions of Arab Muslims for American newspapers: "They never invent anything, never learn anything. . . . They are a stupid population . . . all beggars by nature, instinct and education."
Robert Ruark on ISLAM.
Robert Ruark, a popular syndicated columnist in the 1950s and 1960s, sent these reflections back home: "Mohammedans do not think like a lot of other people in this world. They never have. They are almost devoid of what we call kindness and pity. . . . This applies to animals, enemies and their own kind. They derive amusement from torture, from mutilation, of both animal and man."

Tales from the Koran: How Mohammed met his end.
We shove Jimmy DeanR Homestyle Pork Sausage up Mohammed's ass. Then while the Giver strokes me off I shoot my wad in Mohammed's face, after which we force Mohammed to fellate an 800 pound Chester White. Simultaneously, two Hasidic rabbis open their kosher bowels, unleashing torrents of gefilte shit on Mohammed's head and back, while The Giver pumps Mohammed from behind. After the hog shoots its wad in Mohammed's mouth, The Giver shoots his load up Mohammed's rectum. Then, unexpectedly, the Chester White roots out Mohammed's penis and testicles, hungrily biting them off, gobbling them down with full porcine fury. We bury the newly castrated Mohammed up to his nose in pig manure. Two AIDS infected Bowery whores stuff their used condoms and clotted tampax down Mohammed's throat, and crack a bottle of Mad Dog 20/20 over his skull.
We then leave him for the hogs to munch on. Mohammed is swine feed, and by tomorrow, he will be swine manure.

I was just wondering the other day how feasible it would be to use a laser as a communication device between two birds. You can get really nice range with little EM interference with only a wee bit or output power. The one obstacle I kept running into whilst pondering a laserlink was keeping the beam aimed at another bird in a different orbit. Well hot damn and way to go. I guess I was hit in the face with the same muse as the dudes at the ESA just a little bit late and without any satellites under my control to play with...so far.
I'm a loner Dottie, a Rebel.
I wonder when they start selling these lasers for home-to-satellite internet connections... :)
I know it's minimal, but does anyone have any info on how much force the laser they use might exert?
- billn
I doubt this will become widespread
In high school, some of my geekier friends and I communicated small messages via small laser-pointers. It was ok when just a couple of us were doing it, but when we graciously tried to extend this mode of communication with our teachers and fellow classmates, our lasers were taken away by our teachers.
I doubt the ESA would want my high school teacher to take their lasers away.
wow
Considering the vastly different orbit heights (832km and 31000km) surely the two satellittes must be going at very different velocities. A little basic mathes show us :
2 * PI * 832 = 5,227,610m
2 * PI * 31000 = 194,778,744m
So the total linear distance travelled in each orbit is very different (assuming that the two heights are taken from the centre of the Earth. Which they aren't. Can't be bothered to factor in Earth's radius). So, at 7000m/s-1, the outer satellitte would take about 8 hours longer per orbit, evidently showing the relative distance would be changing, and making the targetting process much more of a challenge.
So.. presumably 7000m/s-1 is the speed of one of the satellittes (I'm guessing inner)..
PS. I think my mathes is screwy. Its early. I have no coffee.

By The WIPO Troll, $Revision: 1.10 $
What is "Taco-snotting?"
Good Lord. And what is a "Circle-snot"?
Ewwwww. Why have I been receiving emails from CmdrTaco asking me if he can Taco-snot me?
I can't stop receiving these emails from CmdrTaco!?
Have you ever been Taco-Snotted?
That's horrible. Does "Taco-snotting" have anything to do with CmdrTaco's "special taco"?
Does Jon Katz get involved in any of this? I thought he was a paedophile, not a homosexual.
What's that screaming I hear coming from your basement?
No, thanks. I'm already CmdrTaco's boi toi.

I love you. Why do you use your bitchslapped account, rather than signing up for a new account to post at +1 before getting bitchslapped by the censors here? I guess I should speak for myself, but I don't want to log out and lose all my slashdot customization properties, nor do I want to lose my 50 karma yet.

I have a confession to make.
Last night, I raped and sodomized Mary-Kate and Ashley Olsen. I couldn't help it, they're just so darling cute when they're naked, chained to each other, and begging me not to plunge my penis into their puckered little asses. But I did. Seventeen times.
And I like licking their cute little feet.

I think you got that wrong. Artemis is the relay satellite, SPOT4 is not.
Lan parties in space? Hmmmm? I dig, I dig...
Until they can point those lasers at the ground, too ;)
*sizzle*
Now that's actually more scary than anything else. If a civil institution is capable of laser-linking satellites, I'd say it's pretty much a given that the military is perfectly capable and probably has been for years to deploy lasers for destructive purposes in earth orbit. Who knows what's meanwhile up there? And I thought Star Wars (SDI) has just been US-propaganda to speed up the USSR's economic meltdown...

Is it just me who wonders in amazement at the cynicism over the missile defence tests about whether it's possible to hit a missile travelling at great speed (GPS or no GPS) - and yet now everyone oohs and ahhs and has no problem with NASA aiming a laser at something moving at 7000 m/s... :)

I would put this into context with the latest European military goals. One of the major goals is independence from the US in strategic intelligence gathering. Real-time satelitte images that nobody can intercept are an important step in this direction.
First troll for Osama bin Lager!
Just what we need - Satellites with friggen laser-beams attached to their heads
however, it was demonstrated in the sixties
by concurrent US and Soviet teams (Tatarskii) that
a laser link (although very secure and
promising in terms of bw ) between an earth station and a satellite was not feasible
due to atmospheric turbulence. Maybe
things have evolved now...
Google passes Turing test : see my journal
Sure, you get the laser link up and running fine, transferring all your data, and suddenly a piece of space debris intercepts the path of the laser. So some amount of data is lost.
What kind of redundencies are employed to work around this problem?
Or isn't it a problem at all?

Now all they have to do is increase the intensity and they've beaten us to Strategic Defense Initiative.

Seen from this side (Europe) of the pond (and from somebody who actually lived for 2 years in Toulouse,
and visited once the space installations, but that's off-topic) I find this rather interesting for inter communication betwen satellites.
Such a system allows global coverage with a few geostationnary satellites in a ring (say six or 8) which communicate with each other. You only need two hops between two opposite satellites because of the pesky obstacle called the earth in the middle (actually, now that I think a little about it, an odd number of regularly spaced satellites might be better to avoid said obstacle). Note that communication between
geostationary satellites is far easier since their relative position is fixed.
With this you cover most of the globe, except high latitudes and the distance to the satellite might be a problem for some applications (antenna size, emitter power required). So for the non-fixed/low altitude situations, you need lower altitude stallites which communicate with the geostationnary ones (hopping from one to the other depending on its position). This makes a lot of communication channels, however the advantages of optical links are the extremely high directivity which allows you to use the same channels (actually optical wavelengths) without risking interference. Of course this is this part of the communication which is tricky because of tracking.
This eliminates a lot of the base station system infrastructure (you still need one station to control the whole system, but that's unavoidable). I believe that a system like this will in the long term make satellite phones affordable. Iridium, etc, failed because of cost in my opinion, but that's exactly a case where a lower cost will make the demand explode
and turn it into a profitable business (perhaps even very profitable once you get the cost down to the point where many people can afford it).
I also prefer it very much to having the coutryside peppered with antennas for mobile phones, which does not prevent me from being
outside coverage when moutaineering, etc.
Oh, well, speleologists would still have problems, but that's their choice to remain hidden inside the earth

So, yes i'm nit picking.
Now the question is: Why isn't it in Geo-stationary orbit? Am I missing something?
I work with free space lasers as part of my PhD and I can assure you they can be an absolute b*stard to align properley, even accross a small lab bench into a detector. Hats off to em!
I'd be interested to know what wavelength these devices operate on. (I'm assuming they are semiconductor devices as nothing else would be light enough to launch into space) Blue semicondutor lasers (with nitrogen doping) are becomming cheaper and cheaper and can carry more data (because of the shoter wavelength) per sec but may not be as reliable as "traditional" longer wavelengths.
A few months ago we tried rigging up a "laser ethernet" conection from our physics dept to our house (its line of sight). Only by making teh beam very divergent did we manage to get any sort of alingment, and that was on a clear day! It was nowhere near good enough for us to be able to use the universitys fat pipes from home!
Anyone quoted by a reporter knows how little they understand
Don't believe what you read is the truth.
There's also an article on the Artemis satelite.
It was put in a too low orbit but fortunately it
carries two different experimental ion propulsion
systems. With the ion propulsion the satelite
it now being put into geostationary orbit, which
is quite a feat as the satelite has to travel
thousends of km's against Earth's gravity.

Operating wavelength is between 800 and 860 nanometer. Probably a GaAs laserdiode
I thought it might be.
Most space stuff tends to rely on older tried and trusted technology, rather than anything that might go wrong (Its not easy to fly into space to replace a blown diode!) That and I'm sure the bit-rate available over ~830nm is more than adiquate.

I live in Toulouse - the AZF chemical factory exploded on sep 21 (terrorism?), killing 100, seriously injuring 2,000 and destroying 15,000 habitations + 1 hospital.
I don't think the ground station for satellites went unharmed, especially because it was not far from the chem factory.
Interesting side effect of this is that these communications can't be intercepted, unlike RF/microwave broadcasts.
D.
50mbps is a great advance in speed, if i remember correctly, the spacestation MIR had just about 9600 bps data connection.
The optical transfer is a very interesting way to go for high bandwidth.
Perhaps this could be a better solution for communicating between sites down on earth as well. Today's microwave solutions may be cheeper, but they're really speed limited...

My girlfriend works at NASA as a Tech, and something I hear all the time is about their funding, and how it's really hard to get anything real done around there without a whole lot of BS. PHB's trying to get Win2K on P5-75's; and some other obsurd stuff to just make you question why we've cut their budge a lot.
I disable sigs...do you?
Something as important as satellites should all be running open source software though. Is this satellite to satellite software open source?
Anyone know anything more about this? Could this be a way to get a link to and from the ground?
73,
dit dit
So the sentence:
The link is running at 50Mbps and the two satellites are currently orbiting at 832km and 31000km respectively.
Is just code for:
The system is running at Full Power and the two satellites are currently orbiting above Washington and Moscow respectively.

It is called metempsychosis -- soul travel (of the psyche) from one place to another. If this astounding SlashDot report is true, then our lush, green planet Earth stands on the space-port doorstep of intelligent ethereal beings flitting about from satellite to satellite on a beam of laser light.
But what happens, Scottie, if you are beaming up an AI Laser-Mind and you miss the receiving satellite? Does the robot soul or consciousness sail off eternally into the far reaches of the universe?
And how will this satellite-to-satellite laser-beam technology be used more mundanely, before the arrival of Technological Singularity?

How feasible is it to listen in on point to point laser transmissions like this - is it possible at all without subverting the original laserbeam ? maybe reading from point of origin (i.e. line of sight to signal originator?) ...
broken?!
Now THAT is what I call P2P communication!
russians vs the world... in quake via satellite laser!
on that topic, when are we gonna see paintball parks in space? rocketjumps...
That sounds like a difficult task to me, especially two satellite running at different orbit. With distance that well over 2000 km, a .1cm error could lead to few hundred meter different and the other end. I am not sure how they did it, since the satellites are not exactly stable objects in the space.
So, how much energy can you cram into a laser beam these days? Anyone lazed ionizing UV and soft Xrays yet? Imagine a nice sharp beam of gammas. Yikes, I'm vaporized.
DMCA, Hollings, Palladium. What might have sounded like paranoia is now common sense.
What amaze me with this kind of PR is that they always use large number to impress people.
The fact that the linear speed difference between the two satellites (from previous post, I assume that the 7000m/s is the speed difference between the two satellites) is not very important. What is important is the angular speed.
It is a lot easier to target an object moving at 100Km/h at a distance of 100 meters than to target the same object at a distance of 10 meters.
Ver precise, and even better, incapable of intercepting transmissions. Good to see this coming to light. "Weeeeery eeenteresting."
Of course, when are we going to see this technology used to guide in laser guided bombs and missiles from sattelite? Or, do we already have it and we don't know about it?
It seems to me that this is just an incremental advance from older satellite-to-satellite communications systems.
Military satellite networks, for example MILSTAR have already implemented very narrow beam communications between satellites. This has been necessary to prevent interception or jamming of the signal.
The advances here probably relate mostly to greater-precision mechanics and more powerful CPUs. I don't know if the data rate mentioned is a big leap or not, but considering the fact that the MILSTAR network carries all the photographic and video intelligence gathered by NRO's Improved CRYSTAL satellites the MILSTAR bandwidth must be pretty impressive too...

McDonnell Douglas (now part of Boeing) received a defense contract to do this exact thing in 1986 - That's right, 15 years ago. As far as I can discern, they actually accomplished the goal. I believe the technology was called "laser crosslink". Anyone know more? Is this junk classified like all the other good stuff?

I had an interview with Lincoln Labs last month (www.ll.mit.edu) and the interviewer was the project manager for a similar project. He said that they were able to establish an optical link between two satilites last summer under a grant from DoD.
DoD generally doesn't release anything until its old news, but its interesting that ESA is trying this.
JPL has in the works a mission to link three (possibly more) small satilites together, preping the way for doing large apature astonomical work, using three seperated mirrors with the distances precisly calulated between them. Something similar to the Keck, but up in space.
