NASA Fires Up Experimental Space Internet For Robot Control
coondoggie writes "NASA said today it had teamed with the European Space Agency to successfully test an experimental version of an 'interplanetary Internet' to control a robot on the ground in Germany from a laptop onboard the International Space Station."
Jeesh, it is a separate network, not a new "internet". People writing technical articles should collaborate with technically skilled people prior to submitting articles. More often than not, they go with option 2 and look foolish to people with technical knowledge. *sigh*
-The wise argue that there are few absolutes, the fool argues that there are no probabilities.
Doesn't that require it to involve more then 1 planet?
is it IPv6?
Hmm, this sounds suspiciously like something we've done before.....
Whats is the ping time for Proxima Centauri gonna be?
(2260080*2)s + ~10ms ?
Will someone please let John Conner know that the latest Skynet activation date is November 8, 2012. Time for another Terminator movie to push the date back again, before it becomes self aware!
If we're controlling robots from space then I for one welcome our new robotic underlords.

The ISS, as far as I can tell, already has access to the Internet. This is a new set of routing protocols designed to be more useful over intermittent and high-latency links such as those present in space.
We are here to protect you from the terrible secret of space.
For one thing, it would be quite a shocker to me to discover the ISS being without Internet access. For all we know, /. is trolled by astronauts daily.
For another, who the heck wrote this summary?
Latency... quantum entanglement, please take care of it!

Must be a slow month on the ISS. There's no reason that testing this should actually involve having someone in space operate a robot on the ground.
The Last Question by Isaac Asimov © 1956
From http://www.multivax.com/last_question.html
The last question was asked for the first time, half in jest, on May 21, 2061, at a time
when humanity first stepped into the light. The question came about as a result of a five
dollar bet over highballs, and it happened this way:
Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As
well as any human beings could, they knew what lay behind the cold, clicking, flashing
face -- miles and miles of face -- of that giant computer. They had at least a vague notion
of the general plan of relays and circuits that had long since grown past the point where
any single human could possibly have a firm grasp of the whole.
Multivac was self-adjusting and self-correcting. It had to be, for nothing human could
adjust and correct it quickly enough or even adequately enough -- so Adell and Lupov
attended the monstrous giant only lightly and superficially, yet as well as any men could.
They fed it data, adjusted questions to its needs and translated the answers that were
issued. Certainly they, and all others like them, were fully entitled to share In the glory
that was Multivac's.
For decades, Multivac had helped design the ships and plot the trajectories that enabled
man to reach the Moon, Mars, and Venus, but past that, Earth's poor resources could
not support the ships. Too much energy was needed for the long trips. Earth exploited its
coal and uranium with increasing efficiency, but there was only so much of both.
But slowly Multivac learned enough to answer deeper questions more fundamentally,
and on May 14, 2061, what had been theory, became fact.
The energy of the sun was stored, converted, and utilized directly on a planet-wide
scale. All Earth turned off its burning coal, its fissioning uranium, and flipped the switch
that connected all of it to a small station, one mile in diameter, circling the Earth at half
the distance of the Moon. All Earth ran by invisible beams of sunpower.
Seven days had not sufficed to dim the glory of it and Adell and Lupov finally managed
to escape from the public function, and to meet in quiet where no one would think of
looking for them, in the deserted underground chambers, where portions of the mighty
buried body of Multivac showed. Unattended, idling, sorting data with contented lazy
clickings, Multivac, too, had earned its vacation and the boys appreciated that. They had
no intention, originally, of disturbing it.
They had brought a bottle with them, and their only concern at the moment was to relax
in the company of each other and the bottle.
"It's amazing when you think of it," said Adell. His broad face had lines of weariness in it,
and he stirred his drink slowly with a glass rod, watching the cubes of ice slur clumsily
about. "All the energy we can possibly ever use for free. Enough energy, if we wanted to
draw on it, to melt all Earth into a big drop of impure liquid iron, and still never miss the
energy so used. All the energy we could ever use, forever and forever and forever."
Lupov cocked his head sideways. He had a trick of doing that when he wanted to be
contrary, and he wanted to be contrary now, partly because he had had to carry the ice
and glassware. "Not forever," he said.
"Oh, hell, just about forever. Till the sun runs down, Bert."
"That's not forever."
"All right, then. Billions and billions of years. Twenty billion, maybe. Are you satisfied?"
Lupov put his fingers through his thinning hair as though to reassure himself that some
was still left and sipped gently at his own drink. "Twenty billion years isn't forever."
"Will, it will last our time, won't it?"
"So would the coal and uranium." "All right, but now we can hook up each individual spaceship to the Solar Station, and it
can go to Pluto and back a million times without ever worrying about
Internet2 is not even released to everywhere. :P

Did NASA's space network immediately encounter an existing alien network and go mad?

Oh and yes, theoretically this extends the Internet in the same way that various other protocols do, eg 6lowpan etc.
And yes, as it is store-and-forward it looks an awful lot like SMTP.
Enjoy ;)

I don't get it. Remote control radio links have been used for decades. NASA itself has used radio to control their robots on Mars for quite a few years, and that has to deal with a time-delayed transmission due to distance. This is simply not news.
