Spacex tell it’s on track to launch another batch of polar SpaceX starlink satellites from the west coast as soon as 10:39 am PDT ( 17:39UTC), Thursday, July 21st …..!
Falcon 9 called a hold at T-46 seconds ahead of today’s planned launch of Starlink. Now targeting tomorrow, July 22 at 10:39 a.m. PT

On top of presenting one of the fastest Falcon 9 booster turnarounds ever, SpaceX’s Starlink 3-2 beginwill more than halve the fastest turnaround of its Vandenberg Space Force Base (VSFB) SLC-4E pad, probably rendering it capable of launching dozens of times per year.

SpaceX Starlink break the Record of Falcon 9
Barring delays, Starlink 3-2 is plan to launch from SLC-4E just 10 days and 14 hours after the same pad supported Starlink 3-1. The recent record – 22 days and 11 hours – was set between the launches of Germany’s SARah-1 radar satellite and Starlink 3-1, meaning that SLC-4E is on track to sharter its turnaround record twice in a row.
For most of the time since SpaceX began using SLC-4E for Falcon 9 launches in 2013, the pad has rarely supported more than one launch every few months. Between 2013 and 2020, the pad supported a total of 16 successful Falcon 9 starts 15 occurred between January 2016 and November 2020, averaging one launch every four months and never flying duple in less than 36 days. In the middle of January 2019 and September 2021, the pad only lifted up three launches and even went 17 months without a single use.

Evident upgrades to the pad’s turnaround capabilities have allowed it to support more launches than usual. In the ten months since SLC-4E depart its hibernation period, it’s lifted up nine Falcon 9 launches – five for Starlink and four for consumer. Prior to 2021, SLC-4E never support more than six launches in a ten-month period, meaning that the pad is already usable at a 50% higher capacity.
SpaceX, however, apparently was not satisfied and is on track to substantially expand SLC-4’s operational constraints yet again, more than halving its minimal demonstrated turnaround time. By means , that also dual the pad’s operational ceiling, meaning that it could theoretically support about 34 begins per year with no downtime. SpaceX appears to have attained that expansion by applying the same upgrades it already made to its two East Coast launch pads, LC-39A and LC-40 which both set respective turnaround records of approx nine days and eight days earlier this year. SLC-4E will easilybookend the two with its imminent 10.7-day turnaround.
Of course, no launch pad routinely commands at its demonstrated minimum
But a leap forward like SLC-4E’s (22.5 to 10.7 days) all but guarantees that the pad will be able to launch far more frequently as long as rockets and payloads are obtainable. Over the last seven months, LC-39A has median one launch every 19 days – more than twice its 9.1-day turnaround record. LC-40, which normally deals with simpler missions and only one of three Falcon rocket variants, has directed one launch every 13 days over the same period – closer to its 8.2-day record but still a ways off.
Even if SLC-4E’s average cadence settles somewhere in the middle of SpaceX’s other two pads going forward, it will still likely double its contribution the company’s annual launch cadence and support expedite the deployment of its Starlink internet constellation. If all three pads control an average of about one launch every two weeks, a goal that’s well within reach, SpaceX will have the ability to launch 72 Falcon rockets per year – more than any other family of rockets in history.
Pad apart, Starlink 3-2 will be Falcon 9 booster B1071’s 4th launch overall and 2nd launch in 33 days
SoaceX’s fifth fastest Falcon booster reuse since the operation began in March 2017. Tune in below around 10:30 am PDT (17:30 UTC) to observe Falcon 9’s 32nd launch of 2022 SpaceX broke many records on the Starlink Group 3-2 mission. Begin from Space Launch Complex 4 East (SLC-4E) at the Vandenberg Space Force Base in California, the Falcon 9 Block 5 placed 46 Starlink internet communication satellites into the third bomb of the constellation.
Liftoff was arranged for July 21 2022, at 10:39 AM PDT (17:39 UTC) but the countdown was aborted at T- 46 seconds due to a valve sensor reading on the first phase. Launch favourably occurred at the same time on
July 22, labelling SpaceX’s 32nd launch of 2022. This beggared SpaceX’s 2021 record of most launches in a year when they launched 31 times.
With the eventual goal of being capable to turn around SLC-4E as quickly as SLC-40 in Florida, SpaceX has been making a huge number of upgrades to the Transporter/Erector (T/E) and pad infrastructure at pad 4E. The T/E is answerable for transitioning the Falcon 9 vehicle from horizontal to vertical. Once vertical, it deliver the vehicle and payload with structural support, power and telemetry and is utilized to fuel the vehicle through the Quick Disconnects (QDs).
SpaceX’s upgrades to SLC-4E have allowed for drastically reduced turnaround time in the mid of launches to just 11 days and 16 hours between Starlink Group 3-1 and Starlink Group 3-2. The earlier record was 22 days, 11 hours, and 20 minutes between SARah-1 and Starlink Group 3-1. This also marks the speedy turnaround time for a nonthrowback T/E.
The booster uphold this mission is B1071-4 which has flown 3 earlier mission. This launch spot the 166th launch of the Falcon 9 and the 104th launch with a flight-proven booster.
Conclusion
On top of presenting one of the fastest Falcon 9 booster turnarounds ever, SpaceX’s Starlink 3-2 beginwill more than halve the fastest turnaround of its Vandenberg Space Force Base (VSFB) SLC-4E pad, probably rendering it capable of launching dozens of times per year.
