How long did it take for the SLS to rollout to the pad?
About 9h30 but don't have the exact duration at this time...

Nice! They shaved over 30min from the first time!

Finally, the total duration of the operation is 10h32, with the lowering and hard mate of the MLP onto pad 39B supports.

Notable remarks from Wednesday morning's WDR press conference.

CBT = Charlie Blackwell-Thompson, Launch Director for Exploration Ground Systems
JF = James Free, Associate Administrator for Exploration Systems Development

09:11 CBT: Rollout & preparation for WDR:
* Rolled out a few minutes past midnight on June 6; hard down on the pad just before 11:00 EDT.
* Pad validations (several day testing of services and connectivity between Pad & ML and back to LCC) complete.
* Booster servicing completed over weekend, including hypergolic fuel loading for Booster TVC (which will be tested inside 30 second mark of WDR).
* Booster & Engine inspections completed Tue.
* Engine service platform lowered Wed morning.
* LO2/LH2 service preps completed Tue. Core Stage and ICPS powered down; will next be powered up for WDR.
* Pre-test briefing on Friday.

11:19 CBT: WDR schedule:
* Call to Stations: Saturday, 18 June, at 17:00 EDT.
* Propellant Loading: Monday, 20 June, at 07:00.
* T-0: Targeted at 14:40. Plan for a 2 hour test window.
* Will count down to about 33 s, stop, recycle, then count down again to about 10 s.

18:06 CBT: Response to Q from Philip Sloss re repeat of previously conducted tests:
* Yes, plan to repeat the Stop, Flow, & Recovery test, as well as recycle operations.

25:52 CBT: Response to Q from Philip Sloss re pad flow for launch attempt:
* Was just working on latest pad flow schedules yesterday.
* Several days already removed from flow since Program Specific Engineering Tests were completed following WDR1 rollout.
* Will continue to look at efficiencies to shorten future flows and expect that launch attempt flow to be even shorter.

28:35 JF: Response to Q from Michael Greshko re secondary payloads:
* Will fly secondary payloads whenever they can, but nothing specific to announce re Artemis II or III.
* 6 of 10 Artemis I secondary payloads will be recharged when SLS is returned to the VAB prior to launch attempt.
* Other 4 will not be recharged "for a various set of reasons"; predicted battery charge degradation is being looked at and discussed.

34:15 JF: Response to Q from Irene Klotz re Artemis I launch period:
* Late July/Early August period not feasible. Earliest feasibly launch period will be latter part of August.
(Late August period = Aug 23-29 & Sept 2-6 -- Blackouts on Aug 30, 31 & Sept 1)

35:27 CBT: Response to Q from Eric Berger re potential interference from SpaceX's Globalstar FM15 Falcon 9 launch from SLC-40 early (00:25) Sunday morning:
* Will not be an issue.
