Targeting Sunday, September 4 for Falcon 9’s launch of 51 Starlink satellites and Spaceflight’s Sherpa-LTC to orbit from Florida → http://spacex.com/launches/sl4-20/
SpaceX is targeting Sunday, September 4 for a Falcon 9 launch of 51 Starlink satellites and Spaceflight’s Sherpa-LTC, an orbital transfer vehicle, to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 10:09 p.m. ET (02:09 UTC on September 5), and a backup opportunity is available on Monday, September 5 at 9:39 p.m. ET (01:39 UTC on September 6).The first stage booster supporting this mission previously launched Arabsat-6A, STP-2, COSMO-SkyMed Second Generation FM2, KPLO, and two Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.A live webcast of this mission will begin about five minutes prior to liftoff.
According to the official mission page, it's 51 Starlink sats + SHERPA.Also, the booster is B1052.7 instead of B1067.6 as previously reported. That's a pretty wild turnaround because B1052 was still lying in Port Canaveral on August 17:
Good Moaning!🐓☕️☀️HAPPY LAUNCH ATTEMPT DAY!!! 🚀 Tonight, #SpaceX is slated to lift off their #Falcon9 B1052-7 for #Starlink and #VarunaTDMLaunch is expected at 2209 EDT (0209, 09/05 UTC)
It's launch day! Our Sherpa-LTC, carrying an exciting customer payload, is targeted to lift off on the Starlink mission at 22:09 local/Eastern time, 19:09 for those of us on the West coast.🚀
Not just another Starlink mission: tonight, SpaceX will launch a communications technology demonstrator for Boeing, along with 51 Starlink satellites.By Elliot Mai (@Eli_Mai1):https://www.nasaspaceflight.com/2022/09/starlink-group-4-20/
