NSF Threads for Starlink 2-5: Discussion

Launch February 17, 2023, at 19:12 UTC (11:12 am PST), from Vandenberg SLC-4E, on booster 1063-9. First stage successfully landed aboard Of Course I Still Love You.

Payload 51 Starlink satellites to 70 degree orbital inclination on a south-southeastern trajectory. Initial orbit 223 x 335 km.

Starlink v1.5 satellite mass is now about 300kg after the addition of laser ISL terminals.

I think there's a typo/copy paste error, 2-5 vs 2-6.

Looks like SpaceX did a booster swap again:

B1063 continues to be shuffled down the schedule: Starlink 2-4 to Starlink 2-6 to Starlink 2-5.

Assuming a Vandenberg Falcon 9 launch cadence of circa one launch every 10 days, we should have news of this launch soon.

Every 10 days would be amazing but I'd settle for 2 Vandy launches per month.

New NGA hazard zone appeared last night, overnight from 2/9 22:31 to 2/10 05:33 PST, and again the next night. Track and timing are typical of a missile test. Assuming the same SL Delta 30 launch crew, I'd guess another launch would not be sooner than 48 hr after that (2/12 dawn), depending on its time of day.

The interval between launches could be reduce for upcoming Starlink missions. Since those satcoms are more rugged and occasional failures is expected, resulting in less prep time before launch. Maybe SpaceX could attempt a surge of 5 Starlink launches in a 40 day period in the future.

Here's an NGA generic Hazardous Operations notice out of Vandy that might be a Rocket Launching notice in masquerade.

The dates match, but the times are later than the FAA information, and also don't get earlier day-to-day.

Thoughts?

They probably changed it to match the notice.

Map from the NGA notice. Not sure about the times, but the ground track does match the mission's 70° orbital inclination.

Like the earlier launches in group 2, the FAA times are separated by 1 day minus 14 min, but the NGA times were constant day-to-day. The long odyssey of Starlink 2-4 (Nov-Jan) included announcements from Celestrak with delicious precision, refining that daily shift to 13 min 50 sec. And those times from FAA, NGA, and Celestrak showed that the actual planned launch time is bracketed by wide hazard-avoidance periods that usually begin about 20-30 min before launch.

So for Starlink 2-5, I think the not-yet-announced "actual" launch time is just bracketed differently by the FAA and NGA hazard periods.
