South Korea says 2022 moonshot on track, will test interplanetary internet and search for water

South Korea's first lunar expedition is on track for lift-off in August 2022. The country's Ministry of Science and ICT updated the nation on the progress of the Korea Pathfinder Lunar Orbiter – an effort to place a satellite around Luna. The Ministry made a fuss about the successful integration of ShadowCam, an instrument …

So DTN is basically IP protocol with another layer on top to manage storage and connectivity between nodes. Each node stores the data its received from the previous one. It then sends a receipt, if the former node does not receive the receipt, it tries to send the data on again.

so for TCP that reduces the resend times that would come from having to resend the data millions of miles away. Not sure what the advantage is for UDP. If you are sending UDP, presumably packet loss is not critical such as real time performance data where the resend times would be larger than the data refresh times.

It still sounds like you would need a lot of nodes in orbit somewhere, and presumably you would want multiple paths to take care when one node is not in line of sight, so you would need to deal with data duplication at some point.

DTN =~ UUCP?

Re: DTN =~ UUCP?

I was thinking more along the lines of NNTP or FidoNet :-)
