Is there any possibility for twilight phenomenon or is it too early?
T-45 minutes. (I was getting a bunch of 504 errors, which resulted in my post being deleted.)
T-30 minutes.
Request for a five minute hold 10:39:16 UTC and resume 10:44:15 UCT.
T-15 minutes. Hearing "Abort safing 6."
Nogo for launch. Hearing a fire alarm in the control room and had to evacuate building.
Going through the launch abort procedure. I think I'll call it for tonight.
See you same bat channel, same bat time tomorrow!
NASA webcast just ending, they will return at 4am EST tomorrow (9am UTC).
That puts ISS rendezvous at Wed Nov 9th 8:30am UTC, with capture at 10:05 UTC.
Is the presence of the SeaLion and UtProSat-1 cubesats from the VLEO project confirmed?
This paper published earlier this year says they were delayed to NG-19 in 2023:
Slated to launch on NG-18 in August 2022, the Ut ProSat-1 mission demanded only a little over a year to go from initial concept to delivered cubesat. Though the launch slipped to NG-19 in February 2023, the pace was hardly less demanding of a team comprised of nearly all students

Today’s Launch Postponed
Rob Garner Posted on November 6, 2022
Today’s launch attempt of Northrop Grumman’s Antares rocket and Cygnus cargo spacecraft from NASA’s Wallops Flight Facility on Virginia’s Eastern Shore has been postponed. The launch was scrubbed due to a fire alarm at Northrop Grumman’s Cygnus spacecraft control center in Dulles, Virginia.
The Cygnus spacecraft and Antares rocket remain healthy at the Wallops launch site.
The next launch attempt will be Monday, Nov. 7, in a five-minute window that opens at 5:27 a.m. EST. Weather for that window is currently forecast as 75% favorable: High pressure looks to continue to provide tranquil weather to the Mid-Atlantic before breezy conditions impact the Wallops area Tuesday. Live coverage will begin on NASA TV and nasa.gov/live at 5 a.m. EST.
