Just one planned date 8th July 2025 in next 6 months seems unusually little. Anything going on to cause such a paucity of planned dates?

Independence Day 3-day holiday weekend for at least some of the staffs?  🇺🇸

Also ASDS turnarounds for both JRTI and ASOG.

Add/edit speculation:
There may be a NROL or USSF launch that will appear on short notice.  Or a confidential commercial launch.


Falcon 9 first stages are now cleared for use up to forty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

Booster B1077-22

SpaceX is targeting Tuesday, July 8 for a Falcon 9 launch of 28 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 1:48 a.m. ET, with backup opportunities available until 5:47 a.m. ET. If needed, additional launch opportunities are also available on Wednesday, July 9 starting at 1:26 a.m. ET.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This will be the 22nd flight for the first stage booster supporting this mission, which previously launched Crew-5, GPS III Space Vehicle 06, Inmarsat I6-F2, CRS-28, Intelsat G-37, NG-20, TD7, and 14 Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.
