Quite the launch cadence at the moment

As one mission ends, another begins. The action is almost nonstop here in the port!

Fairing scooper, Shelia Bordelon, has departed Port Canaveral ahead of this weekend’s #Starlink mission.

What's the source of this?

Also, Starlink L28 should also launch in May, how do we know Capella 6 won't be on that one?

Just received clarification from @SpaceX that there are only 52 #Starlink satellites and 2 rideshares on this  launch.

Celestrak shows 569x582, so this is Capella rideshare

That’s very different from the other Starlink launches recently.

Assuming Capella 6 launches on this flight (Starlink v1.0 Flight 26), and assuming that Capella 5 will launch aboard Transporter-2 (or another soon-to-fly Falcon 9 shot)...

What is the other rideshare payload aboard Flight 26?

Stephen Clark confirms that one of the rideshares is a Capella satellite. The other one is still unknown.

Capella confirms to me they have one radar satellite launching on the Falcon 9 mission Saturday evening. The identity of the other rideshare payload remains unclear, for now.
GO for launch, GO for age of reflight

I'm waiting for the final pre-flight blurb from SpaceX before believing there are two rideshare payloads.  The switch from two to one Capella sat was quite late.

I’m thinking though that if Mr Kelso received notice from SpaceX on May 12 that there were two rideshares, it would be well after payload  encapsulation.

SpaceX is targeting Saturday, May 15 for its next Starlink mission launching aboard Falcon 9 from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The instantaneous window is at 6:54 p.m. EDT, or 22:54 UTC, and a backup opportunity is available on Sunday, May 16 at 6:33 p.m. EDT, or 22:33 UTC. On board this mission are 52 Starlink satellites, a Capella Synthetic Aperture Radar (SAR) satellite, and Tyvak-0130.

The Falcon 9 first stage booster that supported this mission previously launched NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and three Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously supported the SXM-7 mission, and the other previously supported the NROL-108 mission.

Weather is 70% GO, with moderate booster recovery risk.
