Internet on the ISS?

Hello, a bit of triviality if you don't mind,

I know that ISS crew have internet facilities on board, they can exchange
e-mail with their families and such. What I would like to know is how
(un)restricted their access to the internet and the Wild Wild Web actually
is. Like, would they be able to read this newsgroup?

They have no connection to the "internet". There is a proprietary
network that allows the ground to deposit and pickup files from the
computers on the station. That is how emails are transfered. Emails are
processed on the ground and stored in the microsoft proprietary OUtlook
format files which are then moved to the station while crews have
outlook shut down.

NASA would be crazy to allow outlook to be used on the station if it
could receive emails from the internet. (think viri).

Even with existing systems, at least once
a computer virus DID establish itself via the
ISS email system.

OK. I was just wondering.

Surely there are other mail programs, and operating systems that are not
(as) vulnerable to viruses. Also they could keep computers for this kind
of personal use seperate from other systems.

I would not get up in space if there was no internet

Um. They do.

Here's an idea: why doesn't NASA put a network in the sky, with each
orbiter,
rover, space-borne telescope, and any other skyward-launched device
working as
a node? Why not internetwork space? In fact, why not use the existing
Internet?


The commercial internet is porous, insecure, and easy to take down. NASA
should be using whatever secure mechanisms are used by our military.

Which, except on (some) tactical radio networks, is essentially using
internet protocols. Just because you use internet protocols doesn't mean
that you have to be on the internet. You might also look up the SIPRNET
(Secret) and NIPRNET (Sensitive but Unclassified) nets, which are based on
router protocols to tunnel through the commercial internet.

The real problems with using internet protocols out of the box is that they
are not set up for SATCOM, much less deep space communications. TCP, for
example, starts out with small packets and short time outs to wait for
acknowledgements.

The military doesn't, by-and-large, have all that much remote control
stuff.

Well, its already there, as I noted that the comment, John goes out of his
way to ring colleagues on the IP phone when he can.

So, If they have Internet protocol phones, I'd assume they could ring
anywhere, as long as they can get out of the Intranet at Nasa, and out onto
the Internet?

Wait, am I reading this right? They're using VOIP phones on ISS? I'm
not surpised, just... surprised.

Can you imagine... crank calls to ISS? "Do you have Prince Albert in a
can?"

Are these for internal use exclusively (as an intercom system)?

No.

They use VOIP through the OCA. It's not a "VOIP phone" as such.
I think they're still using the configuration shown here, just
replace ISS for Shuttle:

http://www.cisco.com/en/US/tech/tk65...800b53b6.shtml

The audio system, which does implement the intercom function, is
digital but does not use VOIP.

The last I heard, the TCP/IP capability on ISS does not allow
the crew to surf the web. The crew desires this capability,
of course, but it is thought to be too risky. Of course, they
might have changed the rules a week ago Thursday and not told
me.
