Launch Day: Weather is 100% Favorable for SWOT Launch

Meteorologists with the U.S. Space Force’s Space Launch Delta 30 Weather Squadron are predicting a 100% chance of favorable weather conditions for launch, with no primary weather concerns.

NASA, SpaceX, and Surface Water and Ocean Topography (SWOT) launch managers met today, Dec. 9, to conduct a Flight Readiness Review (FRR) at Vandenberg Space Force Base in California. During the FRR, teams provided an update on the mission status, closed out actions from previous readiness reviews, and certified the readiness to initiate final launch preparation activities.

A collaboration between NASA and the French space agency Centre National d’Études Spatiales (CNES), with contributions from the Canadian Space Agency (CSA) and the UK Space Agency, SWOT will be the first satellite to survey nearly all water on the Earth’s surface. Its instruments will observe the ocean’s surface topography in fine detail, as well as measure how bodies of water change over time.

Encapsulated inside the SpaceX Falcon 9 rocket’s payload fairing, SWOT is now ready for its next major milestone. Over the next couple of days, technicians will horizontally integrate the encapsulated satellite to the Falcon 9.

Liftoff is scheduled for 3:46 a.m. PST on Thursday, Dec. 15, from Vandenberg’s Space Launch Complex-4 East. NASA’s Launch Services Program (LSP), based at the agency’s Kennedy Space Center in Florida, is managing the launch service.

NASA, the French space agency Centre National d’Études Spatiales, and SpaceX are now targeting 3:46 a.m. PST Thursday, Dec.15, for the launch of the Surface Water and Ocean Topography (SWOT) satellite. The new date allows for additional time to complete prelaunch processing and checkouts of the SpaceX Falcon 9 rocket.

SWOT will be NASA’s first global survey of nearly all water on Earth’s surface. Scientists plan to use its observations to better understand the global water cycle, furnish insight into the ocean’s role in how climate change unfolds, and provide a global inventory of water resources.

The SWOT mission is a collaborative effort between NASA and the French space agency with contributions from the Canadian Space Agency and the UK Space Agency.

SWOT will launch from Space Launch Complex-4 East at Vandenberg Space Force Base in California.

SWOT Mission Now Targeting Dec. 5

NASA, the French space agency Centre National d’Études Spatiales (CNES), and SpaceX are now targeting Monday, Dec. 5, for the launch of the Surface Water and Ocean Topography, or SWOT, satellite. A SpaceX Falcon 9 rocket will launch SWOT from Space Launch Complex-4 East at Vandenberg Space Force Base in California.

The SWOT project team determined a shift of the launch date was needed in order to complete all the necessary tasks in the lead-up to launch, including transporting the satellite from Cannes, France, to Vandenberg Space Force Base in California.

SWOT is the first satellite mission that will survey nearly all water on Earth. Viewing Earth’s water in higher definition than ever before will inform water equity and water management decisions, provide new insights into Earth’s water and energy cycle, and help prepare communities for rising seas and changing coastlines in a warming climate.
