The NASA Spaceflight article Extended Russian EVA complete – conducts satellite deployments contains a very long discussion about the timing of the CRS-12 launch. Had it missed the "single shot launch attempt" it would have to be delayed by several days in deference to the upcoming Atlas V launch of TDRS-M.


Incidentally, there was an additional item of interest for Dragon’s ability to arrive within this short window of opportunity, relating to the communication systems on the ISS.

which is followed by a long, nine-paragraph discussion of redundancy of communications, the space walk, Dragon's arrival, Field Effect Transistor (FET) Hybrid failure and the Canadian robot Dextre.

I can't follow this article very well at all. There are issues of timing, redundancy and a hint of a possibly impressive number of things that could have been going on at once. But I still don't really understand the point of this. What happened, or what could have happened, that would be so notable?

    $\begingroup$ IMHO, this is a somewhat typical nasaspaceflight.com article, which contains a leavening of current news, padded out by a bunch of semi-relevant info. $\endgroup$ – Organic Marble Aug 20 '17 at 12:33
  • $\begingroup$ @OrganicMarble I see. I get the feeling there is a specific point here, a notable confluence of circumstances that the author wants to highlight. Either something unusual happened, or at least could have happened, that is of particular interest related to DEXTRE perhaps? $\endgroup$ – uhoh Aug 20 '17 at 12:37

    $\begingroup$ When an author writes something like this: "potentially before, during, or after the Russian EVA" they are just making stuff up. "before, during, or after"?? That excludes nothing. And the addition of "potentially" is priceless. $\endgroup$ – Organic Marble Aug 20 '17 at 12:44
