In a press conf for the NASA/CNES SWOT mission, SpaceX's Julianna Scheiman says teams at Vandenberg are inspecting two engines on the Falcon 9 rocket to find source of moisture intrusion. If water, they can proceed with launch tomorrow. If something else, they'll replace engines.
Weather is 100% go for launch, and 100% for the backup day. Good visibility as well.
Scheiman says that if SpaceX determines that the engines need to be replaced, it would result in a delay of “many days” but nothing specific.

SWOT mission coverage will be provided by NASA. Tune in to NASA.gov/live to watch the live broadcast, starting at 3:00 a.m. PT on Friday, December 16.SpaceX is targeting Friday, December 16 for a Falcon 9 launch of NASA’s Surface Water and Ocean Topography (SWOT) mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base. The 10-minute launch window opens at 3:46 a.m. (11:46 UTC).The first stage booster supporting this mission previously launched NROL-87, NROL-85, SARah-1, and two Starlink missions. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base.SWOT is an internationally developed mission to conduct the first global survey of Earth’s surface water. It aims to provide a new understanding of the ocean’s role in climate change and improve the data humanity relies upon for fresh water management.To learn more about NASA’s science missions, visit science.nasa.gov.

The countdown is on! SWOT will proceed toward a target launch of 3:46am PT on Friday, Dec. 16. 🌎 By #TrackingWorldWater, the satellite will help researchers better understand Earth’s freshwater resources, track regional sea level changes, and more. go.nasa.gov/3V0yfqI
Getting up-close with the launchpad 👀The Surface Water and Ocean Topography (SWOT) satellite is ready for launch atop a @SpaceX Falcon 9 rocket. We talked with Christine Gebara, an integration and test engineer, who told us what the teams have been doing to prepare.
