^{SpaceX successfully launched GPS III SV09 last night! This was their third accelerated GPS launch following SV07/RRT-1 & SV08.} The 10th and final GPS Block III satellite is scheduled for launch aboard ULA's Vulcan in March. That satellite arrived in Florida earlier this month.

ЦитироватьEL SEGUNDO, Calif. –  The U.S. Space Force (USSF) Space Access portfolio and Space Systems Command System Delta 80 (SYD 80) are executing a change in launch service provider from United Launch Alliance (ULA) to SpaceX for the upcoming Global Positioning System (GPS) National Security Space Launch (NSSL) mission, GPS III-8.

GPS III-8 will now launch on a SpaceX Falcon 9 rocket which is set to deliver the last GPS III Space Vehicle (SV-10) to orbit no earlier than late April from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Fla.

"The Space Access and NSSL teams' primary mission is to deliver critical capabilities for the warfighter—when and where it's needed," said USSF Col. Ryan Hiserote, SYD 80 commander and NSSL system program director. "With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues.  We are once again demonstrating our team's flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation."

With SpaceX's Falcon 9 rocket now launching the GPS III-8 mission, ULA's Vulcan rocket will now launch the USSF-70 mission, slated to launch no earlier than the summer of 2028...

ЦитироватьGPS III-8 SV10 is nicknamed "Hedy Lamarr". Named by the U.S. Space Force, this satellite honors the Hollywood actress and inventor who, along with composer George Antheil, patented frequency-hopping technology in 1941,  which laid the foundation for modern wireless  communication, including secure Wi-Fi, GPS, and Bluetooth.

Названный Космическими силами США, этот спутник носит имя голливудской актрисы и изобретательницы, которая вместе с композитором Джорджем Антейлом запатентовала технологию скачкообразной смены частоты в 1941 году, заложившую основу для современной беспроводной связи, включая защищенный Wi-Fi, GPS и Bluetooth

GPS III-8 Mission
SpaceX is targeting Monday, April 20 for a Falcon 9 launch of the GPS III-8 (https://sxcontent9668.azureedge.us/cms-assets/assets/GPS_III_8_8d98fe4f3a.png) mission to medium-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The 15-minute launch window opens at 2:57 a.m. ET, with a backup opportunity available at 2:53 a.m. ET on Tuesday, April 21.
A live webcast of this mission will begin about 10 minutes prior to liftoff, which you can watch here and on X @SpaceX (https://twitter.com/SpaceX). You can also watch the webcast on the X TV app.
This is the seventh flight for the first stage booster supporting this mission, which previously launched six 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...
