SpaceX: Starlink Group 4-1 Launch

After a pause in Starlink launches due to phasing in the new generation of satellites equipped with laser cross-links, SpaceX plans to launch 53 Starlink satellites from Florida at 12:19 UTC on 2021-11-13. The launch window is instantaneous. The first stage booster B1058 will be be making its ninth flight.

So, I had to look up “instantaneous launch window”. To understand this, I had to read about “densified propellants”. Lots of contingencies in this business. This makes it all the more impressive. No wonder they call it rocket science.
