SpaceX is targeting Sunday, December 24 for a Falcon 9 launch of the SARah-2 mission to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. The 83-minute launch window opens at 5:11 a.m. PT.
Standing down from launch of the @ohb_se SARah-2 mission to allow for additional pre-flight checkouts. Now targeting Sunday, December 24 for liftoff → http://spacex.com/launches
Yeah SARah-2 payload fairing and B1075 as the booster. Interestingly, the second stage is a Starlink one as it has the velcro pads for the tension rods. It must have been reassigned for this mission in the flurry of delays they've had in the last few weeks out from Vandy.

SpaceX is targeting Sunday, December 24 for a Falcon 9 launch of the SARah-2 mission to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. The 83-minute launch window opens at 5:11 a.m. PT.A live webcast of this mission will begin on X @SpaceX about 15 minutes prior to liftoff. Watch live.This is the eighth flight of the first stage booster supporting this mission, which previously launched SDA-0A and six Starlink missions. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base.
Decoding a METARKVBG = the airfield, VSFB240910Z = the date and time of the report. ...01003KT = the wind conditions. ...10SM = visibility. ...OVC019 = cloud cover. ...12/11 = the temperature and dewpoint. ...A3012 = the atmospheric pressure, a.k.a. altimeter setting.Additional Remarks:RMK AO2A CIG 012V019 BKN V FEW SLP203 = the add-ons, which can give a more complete picture of weather conditions but can also be a little more difficult to decipher, at least for a beginner. This part will require a little more memorization or keeping a guide handy to consult.
Air Mass RGB is used to diagnose the environment surrounding synoptic systems by enhancing temperature and moisture characteristics of airmasses. Cyclogenesis can be inferred by the identification of warm, dry, ozone-rich descending stratospheric air associated with jet streams and potential vorticity (PV) anomalies. The RGB can be used to validate the location of PV anomalies in model data. Additionally, this RGB can distinguish between polar and tropical airmasses, especially along upper-level frontal boundaries and identify high-, mid-, and low-level clouds.
