Recently, the managing editor of the NASASpaceFlight.com, Chris Bergin, suggested that NASA managers are deciding between a "best case" launch date of December 2019 for the SLS rocket, and a "risk informed" date the second quarter of 2020. Bergin is a reliable source of inside information about NASA, and sources subsequently confirmed this information to Ars.

Yes. That is pretty normal for a big programme like this. Donít be so negative om SLS just because it isnít a newspace company thats working on it. And look at all the delays SpaceX is having with Falcon Heavy. I bet even BFR/BFS wonít fly like planned before the 2030í ;-)
I wasn't being negative. I was stating a fact.

Kind of hard to know where to post news about SLS developments sometimes due to proliferation of threads?

If the real launch date once it occurs whether it is scheduled for earlier in late 2019 or not is in May 2020, then the next earliest SLS launch date possible is Dec 2022. Also if that EC would launch before EM-2 but EC launch would not take place until Mid 2023 with the possible quick turn around for another SLS launch (possible but not likely) 6 months later putting EM-2 in 1Q2024. That is 12 years after the start of the SLS/Orion program with it's first manned test launch. At least one problem the availability of the PPE to fly on EM-2 with such a date may not be a concern being that there would be about 5 years to produce the PPE once on contract to meet that date.
