Q: Does NEPA currently categorically exempt satellite systems? Is there any legal basis to Viasat's request for the FCC to consider light pollution?

And Starlink 28 launch is due at 3PM EST. (2:59PM technically). Booster has only flown once befoee, so strange, a babe in the fleet. Fairings halves are both reused! One half on flight 5 and the other on flight 3. So good reuse on fairings as well as booster cores.
Question for this year seems to be: How any Second stages a year can SpaceX manufacture? This is flight 16 of the year, if they keep this pace up, 38 flights is about right. (And Jun 1, Jun 3, and Jun 17 flights booked, and 2 or more Starlinks, just in June!) And this is before they start Starlink out of Vandenberg for the polar orbit missions.
And SN15 was moved off the launch pad (engines previously removed) and looks like it is being moved back to the Prod site. So not likely a reflight in the near future. Alas.
