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*

      You mean I cannot spam the robot with lubrication-Ads?

      It was probably up and running all of 47 seconds before the obligatory Frist Post arrived.

      NASA points out the distinction between this network and the internet:

      From NASA: "The core of the DTN suite is the Bundle Protocol (BP), which is roughly equivalent to the Internet Protocol (IP) that serves as the core of the Internet on Earth. While IP assumes a continuous end-to-end data path exists between the user and a remote space system, DTN accounts for disconnections and errors. In DTN, data move through the network "hop-by-hop." While waiting for the next link to become connected, bundles are temporarily stored and then forwarded to the next node when the link becomes available.

      It seems they are paying attention to security, planning for compromised networks, and non-trusted segments, and it is designed to include
      a number of applications including: sensor networks, mobile devices, use of data mules, military communications which involve stressed disconnected and disrupted networks, along with space-based store-and-forward networks.

      That store and forward bit is key, and would be very nice to have here on Earth, if one could find a way to bolt it onto the existing internet. Currently the closest we have is Email and Cellular Text Messages for this type of stuff. Having been cut off from a remote server due to storm damage with only intermittent contact, I can see where it would be nice to have such capability. (To say nothing about political turmoil where governments try to shut down the net.)

      The name choice is quite simple. If you call it an interplanetary internet, it's much more attractive to interplanetary spammers, thus increasing the chances of making first contact.

      I'd go into further detail, but there's this exiled prince from Gliese 317 who's asking for my help regarding some sort of currency transfer.

    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
