How fast is the internet on the ISS?

[bigdad84]

Just curious, as i've been testing various internet speeds around my town lately, and it had me wondering what those lucky astronauts get for speed up there?

10 seconds with google produced this:

Enjoy!

They don't have broadband Internet. They have file transfer and email which are synchronized several times a day, but they can't surf the web or watch YouTube for example.

Oh they actually published stats for it.

I figured if they weren't catching signals off a passing satellite internet station (typically 368kb/s down 64kb/s up with ~150ms pings for a home connection) they were using a government-reserved wireless WAN link through the same comsats that relay telemetry, patched into NASA's systems through a variety of firewalls and content filters to ensure that no malware can reach the ISS computers.

You know, I've put a lot of thought into... Someday we'll have a mars colony, someday that colony will be big enough it'll need internet. 20ping times such, it'll have to be it's own separate MarsNet, with like regular syncs.... And then when we have the first ExtraSolar colony?

I can't think of anything more boring than a Skype session with Mars.

We could just teleport the information http://www.nature.com/nature/journal/v500/n7462/full/nature12422.html

^ aww that is sad... If we have a FTL communication I could play games together with someone at other planets without any lag

Satellite connections blow chunks.

Yeah ok, I'll get my coat....

If you see any NASA activities, you'd realize they have LIVE video with the ISS. This means they probably have a satellite at a lower or higher altitude with a velocity that keeps it in line with the ISS. This probably results in that satellite being a link between ground servers and the space station. There are many computers around the ISS, but they mainly use those for recording data about the experiments done on the ISS. Alot of people don't realize it, but all those astronauts are really scientists, because the purpose of the ISS is to be a "Orbital Laboratory".

A Martian playing ROBLOX.

*joins gane*

*You have been disconnected for being inactive for 40 minutes*

Just a example, it does'nt have to be ROBLOX. Be really, there will be alot of players that do NOTHING once interplanetary colonization starts taking off.

Older quote from a similar topic:

Let's see, delay to and back from mars is 42 minutes at it's farthest, 6 at it's shortest [source], divide that by 60 = 2520 seconds, x 1000 (to get milliseconds) = OR 360 x 1000 = 360000-2520000 ping.

Sooo, no TF2 on mars

You could play Mars with other aliens

Which is why we have turn-based games. It's like chess in the mail, but way faster.

There's actually some comments in the networking code inside the linux kernel that mention potential problems with latency times if the kernel was running on Mars. It was probably a bit tongue-in-cheek but.... there have been probes sent to mars with Linux in them so... it could be a concern I guess.
