NASA's Next Mars Mission Will Join the Interplanetary Internet 53

New submitter radioedit writes "When the MAVEN orbiter arrives at Mars on 22 September 2014, the spacecraft will join up with the other seven nodes of NASA's interplanetary internet, exchanging data with orbiters, rovers on the surface, and us back on Earth using delay-tolerant protocols. It's the latest part of Vint Cerf's mission (video) to create a giant antenna array across the solar system that'll be able to receive signals by laser from Alpha Centauri."

    Latency of 9 years for a round-trip, and there I thought that calling the helpdesk was slow...

      And that's without Verizon capping the monthly bandwidth for NASA's Unlimited Internet plan.
    • What did you expect. It's Maven crawling along like an Ant. Just infinitely more complex and bloated.

      True – but seriously, if we could get a continuous stream of images and other data back, the four year delay wouldn't matter that much. Of course, the probe would have to be fully autonomous, not need any patching and be prepared to expect the unexpected.

      You think the latency is bad, this will be the slowest deployment roleout in history

    I wonder if they use IPv4 or IPv6.
    And did NASA already pre-allocate subnets and create routing tables for the other planets in advance?

      I was wondering that as well. Actually, I daresay we might need IPv7, w/ 512 bits of addressing, since we have no idea how many aliens are out there, & how many interplanetary nodes would be needed. Earth would have a /384 subnet, and within that, IPv6 would be contained.

        Perhaps we should start by assigning an IP address to every star in the galaxy, and see how many are left over. Or we could try area codes.

      • I read somewhere that there are less than 2^128 atoms in the universe, so we don't need IPv7 until we have cross-universe networking.

      Even if it is IP, it will not be TCP. The IETF has fought against bandwidth resistant protocols for at least as long as I've followed them since going to quarterly meetings from 1988 until 1990. They want to push faster bandwidth and lower latency, which is a good thing, but they just don't get reality. Currently, I manage a network for a company that owns several chains of restaurants. For example, in Seattle we have 10s of seconds of RTT from our data center to several of our restaurants. We used to

        If you'd read the fine article, you'd notice that they apply a protocol (the Bundle protocol) *over* the existing stack. You may continue to use TCP where appropriate.

    An internet for your own use, with no worries about ass-hats fucking with it, or trying to break it. Just think of all of the (non-hardware) obstacles that they don't have to worry about. Surely they have their own fair share of difficulties that we don't have to deal with here on Earth, but they're free to deal with those obstacles in an environment that we all would love.

    Consume all the bandwidth? My god, the article is scary with his face taking up the 23" LCD screen. Hope that doesn't take off, he invaded my personal space.
  • Namely being a laser pointed somewhere not necessarily to shoot and kill. The US and esp. Cerf's boss might learn something from it.
  • How do I go about getting a .mars domain name?
  • I keep thinking what the reaction will be when the Mars colonists start torrenting.. "Yeah? What you going to do about it? If you can get here, you can arrest me.."
