SLC-4E, Vandenberg SFB, California, USA

Starlink 7-16 launched March 19 UTC.

USSF-62 and WorldView Legion Flight 1 will launch in April.

If Starlink 8-1 is not the next Vandenberg Falcon 9 launch, then it should be Starlink 7-18.

Which first stage will be used for this launch?  (semi-rhetorical question)

Falcon 9 first stages are apparently now cleared for use up to twenty times for non-human spaceflight missions, although that number is apparently more restricted for Cargo Dragon and Cygnus than these other payloads.

Available first stages, with UTC date of most recent recovery:
1071.15   Feb 10
1082.3     Feb 15  (save for USSF-62?)
1061.20   Feb 23
1081.6     Mar 4

Edit March 28 UTC: It's B1071.15.

SpaceX is targeting Thursday, March 28 for a Falcon 9 launch of 22 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 7:30 p.m. PT, with backup opportunities available until 11:24 p.m. PT. If needed, additional opportunities are also available on Friday, March 29 starting at 7:30 p.m. PT.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 15th flight for the first stage booster supporting this mission, which previously launched NROL-87, NROL-85, SARah-1, SWOT, Transporter-8, Transporter-9, and eight Starlink missions. (=B1071-15) Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

7:30 PM PDT is about 20 mins after sunset so it should not take the launcher and contrail too long to find sunshine.   

Hopefully it goes on its first attempt.

Rough calculation gives sunlight at about 5 miles up. To reach that altitude won't take long at all.

https://www.accuweather.com/en/us/vandenberg-village/93436/hourly-weather-forecast/2189840

Per AccuWeather, there's no chance of precipitation and it's partly cloudy too. So, ground weather would've been good all throughout the window. Question, however, is were the upper level winds within limits? Did something within the GSE cause a hold?

Unlike ULA, which almost immediately disclosed the cause of the Delta IV Heavy scrub, SpaceX hardly opens up about scrub reasons.

X-CLASS SOLAR FLARE
Giant sunspot AR3615 just produced another strong solar flare. Peaking on March 28th at 2053 UT, the X1-class explosion ionized the top of Earth's atmosphere and caused a deep shortwave radio blackout over the Pacific Ocean. This follows similar blackouts over over the Indian Ocean and South America earlier the same day due to strong M-class flares. AR3615 is active again, and more flares may be in the offing.

Good point. I was viewing that on another channel earlier today.  Yes, that could be.  I still believe a similar X1-CME was the cause of the failed Rocket lab launch last year on that same day that resulted in electrical arching in its wiring. But that's my opinion.

UPDATE #1: @SpaceX is now targeting Mar 31 (UTC) for the next window for the @Starlink Group 7-18 launch. I have removed the data for the Mar 30 window and will post new pre-launch SupGP data once we receive new state vectors from SpaceX.

Wrote this on the thread but I'll mention it here too.

There's potentially three Falcon 9 missions within 5 hours of each other 21:52 UTC, 1:00 UTC, and 2:30 UTC.
LEO is the ocean, not an island (let alone a continent). We create cruise liners to ride the oceans, not artificial islands in the middle of them. We need a physical place, which has physical resources, to make our future out there.

Ah Alas, They didn't ask the weather person on the West Coast.  Pushing the VSFB launch to Sunday will probably occur.  Not trying to jinx it, but it's a large cold storm with high winds, thunder, and snow.

They can push it back to Sunday.  The Center of this storm Low is just offshore from the launch pad with winds and rain.  Maybe like in that movie, they launch when the eye of the storm is right overhead.

Due to the approaching Low, the upper levels are circling around, so the LV will be experiencing winds from one side and then another as it goes up.

This one keeps slipping through the window, so it's getting tight if it'll make it off the pad to make it a hat trick of Falcons in a matter of hours.

Due to unfavorable weather, we are standing down from tonight's Falcon 9 launch of @Starlink from California. Vehicle and payload remain healthy. Teams continue to keep an eye on the weather as they work toward the next best opportunity for liftoff – we will announce a new launch date once confirmed on the Range

I don't believe that FAA ATC information. SpaceX has removed the mission webpage. At this point in time, if you try to go to it via a direct link, it redirects to the website's home page.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 15th flight for the first stage booster supporting this mission, which previously launched NROL-87, NROL-85, SARah-1, SWOT, Transporter-8, Transporter-9, and eight Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

This means that the information that SpaceX sent to CelesTrak is completely bogus.

Primary launch opportunity per CelesTrak = 2024-04-01 02:38:00 UTC, so the FAA ATC information is correct. Given the situation, I wonder why SpaceX removed the mission webpage, and why it's still not back.
It's Easter.  Somebody dropped the ball Easter egg and they'll likely pick it up Monday. 🐣

Edit: Picked it up ASAP!

So why did SpaceX give wrong information to the FAA and to CelesTrak about a launch attempt on early April 1 UTC?

I'm thinking someone was celebrating Easter a little too much while on the job. 🐇

That's a valid question. 🤔 I don't know.

We'll see if TS Kelso revises his launch opportunities listings.

The FAA ATCSCC Current Operations Plan Advisory has been updated to remove April 1.

https://www.fly.faa.gov/adv/adv_spt.jsp

Quote from: FAA
SPACEX STARLINK 7-18, VANDENBERG SFB, CA
PRIMARY:        04/02/24        0230Z-0701Z
BACKUP:         04/03/24        0230Z-0710Z

Nothing was posted by T.S. Kelso on X, but the CelesTrak website has been updated for April 2, but just for the Primary launch opportunity. Normally the only time there is just a single entry is when the launch has taken place and everything has been removed except the launch opportunity that was actually used, as is shown for 6-45.

NOAA forecasts can give you some general hints on conditions before you drive to a launch, especially very high winds, fog, rain and lightning, but the actual launch criteria are quite detailed.  Here's a good doc on launch criteria for crew dragon, I haven't spotted one for uncrewed.

https://www.nasa.gov/wp-content/uploads/2021/07/falcon9_crewdragon_launch_weather_criteria_fact_sheet.pdf

The criteria makes no mention of gusts, but when reading this NOAA wind forecast, it is easy to get the impression that the ground level wind gusts conveniently stop right at 7:00.  I believe that NOAA doesn't report gusts below 15 mph.  At 8pm, wind speeds drop to 6, but you might still have unreported gusts as high as 14.  These forecasts also tell you nothing about upper level winds or the other 10 or more criteria.    IANAMeteorologist, but that's my experience.  (fixed a time)

AJW we get and I report the upper levels via this link.  I've tried making contact to the VSFB meteorological Group via a NASA meteorologist.  No luck getting them to respond.  I was advised to call the Main Gate to get the weather.

Some reusability stats for this launch (Starlink Group 7-18):

Booster B1071.15 turnaround time:
52 days 1 hour 56 minutes
(its previous mission was Starlink Group 7-13 on Feb 10, 2024 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 49.85 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-4E turnaround time:
14 days 0 hours 2 minutes
(the previous launch from this pad was Starlink Group 7-16 on Mar 19, 2024 UTC).

FYI: median turnaround time for SLC-4E is currently 10.97 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet online.
