NASA Wants New Space Net To Sustain Big Data Dumps; Moon and Mars Trips 63

Posted by Unknown Lamer from the world-of-mooncraft dept.
coondoggie writes "What kind of network can support future commercial and government space trips around Earth and support bigger distances to the moon and Mars? NASA is in the process of exploring exactly what technology will be needed beyond 2022 in particular to support future space communication and navigation. The agency recently issued a Request for Information (RFI) to begin planning for such a new architecture."

    There was a proposal recently for another Mars rover for 2020 and I was like, how? We don't have the bandwidth to transmit data appropriate for entering the 3rd decade of the 21st century there... Curiosity is completely gimped due to only being able to send (even by 2013 standards) small amounts of data at certain times etc. etc.

    By that time I'm really expecting, you know, some HD footage at 60fps of the landing and surface operations. At least make that your target and stretch yourself a little.

      Not being able to send huge ammounts of relatively unimportant data doesn't really bother me.

      Sure, it would be nice to send HD footage, but it would be a huge waste as well. There are some very real and big limits they have to work with, considering all that, I think they have a pretty nice rover up there.

      What is scientifically appropriate bandwidth for 2013? What would the Mars Rover designers have been willing to give up to get better bandwidth? More bandwidth comes (generally) at the expense of weight, greater space requirements, and power demands. All of which are a very constrained on a space probe. Or maybe you think they should have delayed Curiosity's launch another 5 years so a newer orbital relay platform could be launched that has more bandwidth?

      I think imaging is the LEAST important part of any space mission. Especially live imaging of moving images. Sure, a couple of science missions give us things like close-up of the moons of Jupiter, etc. but that's really science and doesn't need HD or 60fps (in fact, the visible spectrum is barely worth looking at compared to other wavelengths).

      Pretty pictures don't give NASA money. They go into the gift-shop and a few online licensing rights and that's it. But a decent spectroscopy of something, beamed

    NASA sure does dream big, considering they can barely even get to LEO these days. Their launch capacity has been diminishing steadily for the past 40 years. Thank goodness it's not entirely up to them anymore.

    • I know that it's an unpopular sentiment to say anything pro-nasa/pro-us about the space race, but the United States is the only country developing a super heavy lift vehicle (SLS). Many label it as a jobs program, but that is simply not the case.

        the US knows 'heavy'. that's one thing we know well.

    • Nasa can, and does, get regularly beyond LEO. Off the top of my head:

      1. Spirit and Opportunity rovers - huge success

      2. Cassini-Huygens: Despite some issues, still managed to collect an enormous amount of data on probably the most (or perhaps second most) interesting place in the solar system - including a landing on Titan. Arguably the high point of space exploration so far.

      3. Curiousity Rover - again, hugely successful

      4. MESSENGER probe - has has it's mission extended, having achieved every mission obj

        Humans on other worlds is the standard by which NASA is and should be judged; otherwise it doesn't count. Rovers are sort of neat but they don't count. Telescopes are worthwhile but we don't need a whole NASA agency for that, and in they end they still don't count. Voyager-type spacecraft are worthwhile but again we don't need a whole NASA to simply sling a robot into space.

        Humans on other worlds. Pay for it, or save the money.

  • Reading that summary, it sounds like NASA thinks the distance to the moon and Mars is increasing enough to care about. Also that commercial development of Mars is something they should be concerned about in some nearby decade. Neither of those things is true.

    But here's the architecture:

      • why have a big dish in LEO..

        I meant write GEO, not LEO. The reason is for exactly what you can't get in LEO: a more continuous link to Mars from your ground station. Yes, the earth station uplink antenna and the Earth-orbiting ground-link antenna don't really need to be very big, because the bandwidth is going to be limited by the interplanetary link speed anyway.
