Fueling test and if that works out? After a successful tanking test, they'll roll that momentum into a launch (I've heard 24th and 27th) Let's hope it works!

Quote HistoryQuoted: if it gets scrubbed on Tuesday, then it probably will be rolled back. If they wait longer then the roll back conditions only get worse and it's most vulnerable during the roll back/out. If they try for a launch Tuesday and it's a scrub... then it'll have to weather the storm out at the pad as the wind conditions will not allow for them to roll it back. |

I've heard rumor of possible launch on Monday to avoid a lot of issues with the weather and subsequent rollback.

Sounds like the safe thing to do is roll it back. If they don’t, they can’t scrub since a hurricane would likely exceed 75kts. Seems like a no brainier.

https://blogs.nasa.gov/artemis/2022/09/24/artemis-i-managers-wave-off-sept-27-launch-preparing-for-rollback/
NASA is foregoing a launch opportunity Tuesday, Sept. 27, and preparing for rollback, while continuing to watch the weather forecast associated with Tropical Storm Ian. During a meeting Saturday morning, teams decided to stand down on preparing for the Tuesday launch date to allow them to configure systems for rolling back the Space Launch System rocket and Orion spacecraft to the Vehicle Assembly Building. Engineers deferred a final decision about the roll to Sunday, Sept. 25, to allow for additional data gathering and analysis. If Artemis I managers elect to roll back, it would begin late Sunday night or early Monday morning. The agency is taking a step-wise approach to its decision making process to allow the agency to protect its employees by completing a safe roll in time for them to address the needs of their families while also protecting for the option to press ahead with another launch opportunity in the current window if weather predictions improve. NASA continues to rely on the most up to date information provided by the National Oceanic and Atmospheric Administration, U.S. Space Force, and the National Hurricane Center. |

still waiting and seeing... Roll back could be Monday or early Tuesday. If they don't roll back then they'll try to launch Oct 2. |

They said there was going to be an announcement at 9am today on the rollback. They just pulled the link/reference to that announcement and the coverage feed is just a STEM talk/interview now.

https://blogs.nasa.gov/artemis/2022/09/26/nasa-to-roll-artemis-i-rocket-and-spacecraft-back-to-vab-tonight/
NASA will roll the Artemis I Space Launch System rocket and Orion spacecraft back to the Vehicle Assembly Building on Monday, Sept. 26. First motion is targeted for 11 p.m. EDT. Managers met Monday morning and made the decision based on the latest weather predictions associated with Hurricane Ian, after additional data gathered overnight did not show improving expected conditions for the Kennedy Space Center area. The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system. The time of first motion also is based on the best predicted conditions for rollback to meet weather criteria for the move. NASA has continued to rely on the most up to date information from the National Oceanic and Atmospheric Administration, U.S. Space Force, and the National Hurricane Center throughout its evaluations and continues to closely monitor conditions for the Kennedy area. NASA continues to provide a live stream of the rocket and spacecraft on the launch pad. |

It looks like the SLS and Starship race to first launch is going to get interesting again with reporters saying the SLS' most likely next launch attempt won't be until the Nov 14-27 window. While I want to see Artemis 1 fly, I think it would be fitting for NASA to have to refer to it as the second most powerful rocket in the world if Space X can pull it off first.

I've noticed in the past few weeks articles now referring to SLS/Artemis as "The most powerful rocket NASA has ever launched"  Poor Nasa's going to have to edit lots of video and propaganda at KSC. |
