Is the launch window length known?
I haven't seen anything. Drop zones suggest that it might be going to SSO, so the window could be instantaneous.
Thank you. Now if the clouds and fog can be kept at bay........
Window open: 11:45 UTC / 3:35 a.m. PST / 6:35 a.m. EST
Launch time: 12:26 UTC / 4:26 a.m. PST / 7:26 a.m. EST
Window close: 15:35 UTC / 10:25 a.m. EST / 4:25 a.m. EST
In a case the launch is postponed on Feb. 5, there is a reserve slot at the same time on each of Feb. 6, 7 and 8.
Aimed at a polar obit, possibly sun-synchronous. It will probably be given the name "USA 225".
