Kestrel (Falcon 1 second stage engine) was reported as 6,900 pounds-force (Vac) and Delphin (Rocket 3.1 first stage) is reported as 6,300 lbf (SL); both RP-1/LOX. Are they similar engines?

Boat on the range!

"T-12 minutes, but range is currently awaiting clearance of a boat down range"

Scrub for today.

"Boat could not be cleared in time for us to launch within the window (ends at 9pm PT), and we have to unfortunately scrub for today"

No. Kestrel uses a ~~traditional turbine pump~~ pressure fed engine, while Delphin is electric pump fed.

Kestrel was pressure fed.

Boats. Aargh. Any Coast Guard assets in the region that can run interference, or is that outside the purview? Does anyone know if a NOTMAR was issued?

Would have loved to see this candle light up today.

Quite a day for random private boats in spaceflight, between this and the Dragon splashdown.

🌩️ Update: We won't be making a launch attempt today due to weather (triggered lightning). Our launch window is through August 7th and weather is expected to improve through the week.

On the subject of their window being through the 7th, they appear to have updated their TFR ~~to go through Saturday the 8th to allow for more opportunities.~~ through Friday to match the launch window. (Correction: UTC time conversion error on my part, local time is PDT)
