If the start of the pathway to the Rift has been scouted in the DWE (as per the Galnet post), surely that rules out the gap between the Perseus and Outer arms - and could be the meaning of the watch your six clue? A line extends both ways in space - a vector is directional.
Yes but the opposite end of the R/R line doesn't point in the direction of the Distant Worlds Expedition either.
The actual phrase from Galnet is:
Early analysis of the recovered data indicates that a number of new routes have been scouted, including pathways to Beagle Point, the Core, the Formidine Rift, the Norma Expanse and many other parts of the galaxy.
Something to remember about Distant Worlds is the plan all along was for the "fleet" to break up after reaching Beagle Point. Various commanders are planning to return home following different pathways ... some of these pathways will take them through the core, through the Norma Expanse or even the Formidine Rift. Therefore the statement from Salomé might not indicate that DWE has been to the Rift. This could simply be an indicator that a new pathway, from Beagle to the Rift, has been scouted out.
Given that Salomé is quoted directly in the article my assumption is that this information comes directly from Drew himself ... or at least indicates a direct quote from Salomé in the Live Stream (which I have yet to have the opportunity to watch). It will be interesting to see further clarification in Galnet News in the days ahead.
