Graco's EcoQuip blasting equipment is designed for cleaning-to-surface preparation to the largest and most demanding blasting projects.Our vapor abrasive blasting equipment generates less dust and uses less water and media than traditional wet blasting equipment, saving time and money.Graco offers several EcoQuip models designed for years of solid service.Actually, given the great time lags in communications (and probable bandwidth issues), I would not expect interplanetary Tweets, phone calls or even emails.Point to point communications would most likely resemble texting (including the incomprehensible abbreviations), but you would have anywhere from 1.4 seconds delay to the moon to many hours to Uranus.This means another possible driver for high performance spacecraft would be mail delivery.(Consider a small car delivering 100 DVDs for Netflixx probably is carrying more information than you can access through your home internet connection in a day.)Contracts, magazines, movies, personal messages and anything else which needs more detail than a text message will all be loaded aboard mail servers on fast packets, and blasted to their destinations via the fastest means possible.This of course leads to interesting scenarios where protecting and intercepting mail becomes important for intelligence agencies, business and criminals.

Mail delivery will involve high levels of security and screening of the mail delivery personnel.I doubt anyone will hijack a mail packet in flight, but having a covert operative on board to hack the mail server and download the interesting information is a very real possibility.This sounds very implausible to me.The light speed delays mean that all interplanetary communication will resemble emails with attachments more than phone calls.The immense power required for torchship performance would make interplanetary communication lasers much more economical for sending even terabytes of data, much less an email greeting with a 1 MB photo.Email in space — Should be no problem with this, even if the distances slow it down to telegraph speeds.Text messaging in space — Will be restrained to within a few light-seconds, probably no more than 10 or so.Any longer than that and you might as well send a longer message.Instant messaging — Will probably be restrained to 2-3 light-seconds.Like a phone call, any more delay defeats the whole purpose.Physical packets — Documents that you don't want easily copied, high-density data storage for non-essential information (Movies, music, etc), items that can't be replicated at the destination (Due to lack of facilities), items that shouldn't be replicated at the destination (Gifts), and people (Diplomats, managers, mediators, etc).To expand on Citizen Joe's point, would you like to receive "Male enhancement" emails with the olympusmon.mars address?

How about "Dear Sir, I am the last surviving member of the Europan Resistance front and need your help to transfer $10 billion solars from the Bank of Callisto...."Onvaporizer british columbiaa more serious note, the high bandwidth links would probably be reserved for ship traffic, government and military communications and corporate communications (for companies with the financial clout to get in line for email).vaporizer bielCertainly the Uranus Space Navy would not want the high bandwidth links clogged during their showdown with the Imperial Jovian Navy, nor would they want to risk malware or botnet attacks coming through those links; which suggests interplanetary comms would be tightly controlled and subscribers carefully vetted.Since power and surface area aren't problems on the ground (and to a lesser extent, in orbit), communications would likely be predominantly TO ships while ship to shore (home base) comms would be limited to a confirmation of receipt.vaporizer bahrain

On Earth, we can afford to put up huge arrays to catch the smallest radio signal.Not so much in space.Likewise we can pump a lot of energy into the antenna to send back a longer message with a lot of bandwidth and strength even at stupendous ranges.Now there are some tricks, like omnidirectional beacons and antenna that act as targets for the directional antennae.vaporizer buy amsterdamBut you can only listen to data in the direction of the directional antenna.cryoquip vaporizer catalogueThat might be limited to a single stream.vaporizer capacitorComm relays would likely have at least 4: Signal in, Signal out, Previous relay, Next Relay.By using multiple relays (at least 4 would get you around the sun) you wouldn't have black outs (except at ship orbit).

And then there is the problem with the fragile gimbals needed for all the antennae.In the end, yes, you can communicate via radio.No, it isn't broadband.No, it won't service a population comparable to the internet.It will likely be biased communication.It will still be expensive.There will be extreme needs that keep every carrier busy.So, although you COULD send a digital copy of Pluto Nash to Pluto, you would never get enough priority to use the carriers and thus it would be simpler to put it on a torch or fling it out the airlock.What about relays at Lagrangian points?Everyone knows where those are, and if someone needs to connect they can just link into the network.I don't even think lasers would even be needed.The relays would have high gain antennas to receive the data on broadband signals, and when a ship or colony needs to link in they can query the closest available platform with a much lower-gain antenna.If we can be in contact with various probes (like Voyager probes) at interplanetary distances, on 1970s technology, then I hardly think you would need a giant technological leap to create a system-wide comm network.Granted you won't have the bandwidth of fiberoptic cables, so no browsing for Earth-porn from Callisto, but I don't see communication as much of an impediment.

The only real reason to use lasers (that I see) would be for private (read: military) communications that you don't want intercepted, but with a target area of 90 km in radius, it's not really very private anymore.Surfing the interplanetary web would be a unique experience.Given the reply times measured in minutes or hours, getting a response for a search query would be more akin to making a request at the Library of Congress and then waiting for the attending librarian to go and bring you a copy of whatever they think you asked for (which may or may not be what you were actually looking for).Since we survived the dark ages of dial-up modems, I think we could probably put up with the connection speed of the interplanetary net.I think that interplanetary communications networks would be more like a cluster of 'webs'; one on Earth, one on Mars, one on Luna, ect.The different webs would send updates to each other on a regular schedule via dense-data/high-priority channels, and all other inquries/messages being sent via lower-priority channels.

Most of your routine web activities would be with your local internet, but occationally you'd connect with another world's internet via the systen-wide web.Interestingly enough, this is the way the "extranet" is postulated to work in the Mass Effect games.Essentially all colonies pack with them a web server full of the most needed and demanded data.If the information you are looking for is not on the server the system opens a communication link (FTL in the game) and hits the closest large colony server, and so on, until it finds the info, and it uploads it into the colony's server for easy retrieval later.In the game data storage is no longer an issue, but I assume if storage space is needed and a specific file hasn't been looked at for a while, it would be deleted.However, since most early colonies will be science bases, I would assume large amounts of data will be passed back and forth as scientists on Callisto and on Earth look over the data, form theories and send them back and forth.

It seems like a very fluid form of data exchange is needed even with local "nets".I also doubt early colonies will be very large, or widespread, and it is far more likely the Callisto colony terminals will be linked on a LAN to a single server rather than a network of servers in the first place.Viral propagation is another option.It doesn't guarantee speed or privacy.The idea would be that a message would be sent to any ship that is heading in the right direction that is within range.This could be a very long route.However, since there would likely be relatively few interplanetary vessels (compared to airplanes), Solar Space Traffic Controllers would have the full list of vessels and thus able to chart a route based on predicted paths.While the InterPlanetary Space ships would carry parcels, they would probably also serve as communication hubs for the viral network.That sounds pretty close to how the modern internet functions, with data tracing geographically indirect paths as it goes from place to place.

I like the efficiency of such a scheme: it would use the infrastructure that's already there to create an ad-hoc network backbone.On the other hand, you'd be trading out data security unless you've got some very good encryption (or just plain don't care who else reads your messages).Jean Remy, I was thinking along those same lines.A lot of business/corporate/government entities would end up hosting proxies of their sites and databases on the far-flung colony servers, with periodic updates being beamed back and forth (ultra-secure data being handled differently).With multiple proxies being hosted for a single database, with data exchange rates measured in minutes, how long do you think the system will last until Murphy's Law takes a server down through version conflicts?Viral dissemination works on Earth because of thousands and thousands of privately owned servers.However, even in the best-case scenario of a very developed interplanetary infrastructure, I don't see a lot of traffic in space.

Say two cyclers between every major colonial epicenters (say 2 for Mars, 2 for the Jovian colonies, 2 for Saturn etc...)and a few "moon hopper" shuttles, but those would be so close to their giant primaries getting a Line of Sight on them would be an issue.However the Comm relay platforms suggested are basically Voyager probes without the scientific instrumentation and a known stable orbit.Rather that throwing your message out omnidirectionally and hope that eventually it will reach your destination (because viral dissemination is kind of like shooting blind) you simply bounce the signal of a set number of known (and if want, secure) predetermined platforms.If your goal is to reach as many people as possible (the entire point of viral dissemination in the first place) then target the Cyclers.Chances are good the passengers en route back and forth have personal computers linked in to the ship's server, which keeps updated by linking in to the platforms.The general outlines of communications in the plausible mid-future look a bit like the Victorian era.
