15:46 < maaku> lsneff: there's a working interplanetary transport protocol currently used to relay data packets from Mars rovers to orbiters then back home
15:46 < lsneff> That's on the DSN?
15:47 < maaku> the DSN is just the receiving end of the last link
15:47 < maaku> https://en.wikipedia.org/wiki/InterPlaNet
15:48 < maaku> wikipedia seems in error. it makes it sound like it's cancelled, but rather the first mission which was going to use it was cancelled.
15:48 < maaku> it's been retrofitted to work with existing orbiters and rovers and has been in use for around a decade
15:49 < maaku> http://www.ipnsig.org
15:49 < maaku> The DSN is just the big dishes that receive transmissions from various planetary probes
15:50 < maaku> The relay network protocol itself is how the various pieces link up with each other and mesh network to get data packets from underpowered rovers with small antennas to the orbital satellites with their high-gain transmissions
15:52 < maaku> At first it was used just to get better coverage of the rovers, since there were parts of the day earth was not visible in the sky or the directional antenna pointed the wrong way, but the orbiters could pick up weaker omnidirectional signals
15:52 < maaku> Now the rovers are designed to operate with the relay network as the primary means of communication, as it's so much more efficient.
15:54 < maaku> E.g. I think curiosity and preserverance have really low bandwidth earth antennas that serve mainly as a fallback command-and-control link. Pictures and data flow back via the orbiters.
