SWOT, the latest satellite built by NASA to map water on Earth, completed deployment of solar cells and antennas in 4 days.
NASA released a video on the process on December 29 on Surface Water and Ocean Topography (SWOT) Deployment of the device after flying into space using SpaceX’s Falcon 9 rocket.
First, SWOT needs to open up solar panel systems to help provide energy. After completing this step, the satellite can open important antennas. Experts use telemetry data to monitor and control SWOT. The satellite is also equipped with 4 commercial cameras to record what is happening.
NASA said it takes about 10 minutes to deploy the solar cell. The antenna was successfully deployed in 4 days, completed on December 22, 2022. Two cameras pointed at the KarIn antennas and recorded the scene of the pillars emerging from the satellite and then moving into position. The expert team could not record the moment when the antenna system was fully deployed, but confirmed this stage with telemetry data.
The information provided by SWOT will help people prepare for a warming world.

The SWOT satellite is expected to map water on Earth in unprecedented detail. This will help people cope with climate change and better manage their precious resources. Two KaRIn antenna located at both ends of the pillar, spaced 10 m apart. KARIn will observe eddies, currents and small ocean structures less than 20 km wide.
SWOT is designed to make precise measurements of water depth in Earth’s freshwater bodies and oceans. It will collect information on rivers with a width of more than 100 m and lakes with a width of more than 62,500 m2, the collection range is a 50 km wide strip on either side of the satellite. To do this, radar pulses from KaRIn will bounce off the Earth’s surface and the water surface, then the signal will be received by both antennas.
NASA says the information provided by SWOT will help people prepare for a warming world, helping researchers and policymakers solve some of today’s pressing climate change challenges.
