    I was reading in Space News, lately, that the US Deep Space Network (DSN) was going to be stressed in 2020 with all the incoming Mars probes, and this was before SpaceX pondered sending two Dragons to Mars. The Space News commentary noted that one of the reasons that probes arrive at Mars in a staggered manner is so that the DSN can handle all the urgent traffic (arriving or distressed probes) as well as maintain some routine communications with existing probes. This is part of mission planning for each probe that we send into deep space, and Earth’s space exploration agencies are planning on sending several to Mars in 2020, making it a busy time for the DSN.

  • Edward: Look at the last item in the list of distressed projects at NASA as noted by the GAO. The Space Network Ground Segment Sustainment (SGSS) project is specifically aimed at upgrading the Deep Space Network. And of course, it is behind schedule and over budget.

    Delayed probes might help the delayed DSN. The Chinese five hundred meter radio telescope is online now and could help.

    Sample return missions like Osiris-Rex and Hayabusa and probably a SpaceX mission to Mars in 2022, could return a memory chip with petabytes of data with the highest resolution from all instruments gathered all of the time. Radio would only be needed for managing the mission while ongoing. The big data could be returned physically.
