<h5>What has NASA launched?
</h5>  <p>On 16th December 2022, the National Aeronautics and Space Administration (NASA) launched a satellite named Surface Water and Ocean Topography (SWOT). The SWOT satellite was carried by a SpaceX Falcon 9 rocket and was launched from the Space Launch Complex 4E, Vandenberg Space Force Base in California, USA.</p>
<p>The Canadian Space Agency (CSA), the UK Space Agency, and NASA all contributed to the development of SWOT. SWOT was also built for the French space agency, Centre National d'Études Spatiales (CNES). The satellite's signal was successfully received by NASA after SWOT separated from the SpaceX Falcon 9 rocket.</p>
<p>The satellite seems to be functioning well. In the coming months, SWOT will go through a number of inspections before it begins gathering scientific data. This satellite was launched for a specific purpose. Read on to know what it is. 
</p> <h5>Why was SWOT launched by NASA?

      </figure> <p>SWOT will be used to observe nearly all the water on our planet’s surface. The SWOT satellite will measure the height of water in freshwater bodies and oceans across more than 90% of the surface of the Earth during its three-year mission. At least once every 21 days, SWOT will cross the whole Earth's surface.</p>
<p>It will be sending a lot of data back every day for the scientists to study. One of the numerous advantages the SWOT mission will bring is a much clearer picture of Earth's freshwater bodies. More than 95% of the world's lakes will have data available on them.</p>
<p>Only a small number of lakes worldwide have proper data available for freshwater researchers at this time. That amount will rise into the millions due to SWOT. SWOT will give sea level data along the coast, covering any gaps in places where sensors for measuring sea surface height are not available.
</p> <h5>How will the data from the SWOT mission help?

      </figure> <p>The data from the SWOT satellite will offer new ideas on the relationship between the ocean and climate change, the impact of global warming on lakes, rivers, etc, and the best ways for communities to prepare for disasters like floods.</p>
<p>Researchers can better track sea level rise with the help of coastal data. This will help save those residing in the coastal regions during any kind of disaster. Researchers would benefit from using SWOT data to better study and plan for various situations, such as droughts and floods.</p>
<p>Researchers can also improve flood predictions for rivers and track the effects of drought on lakes by providing information on where the water is, where it's coming from, and where it's going. SWOT will help combat climate change and sea level rise.
</p> <h5>What did we learn from this article?
</h5>  <p>There is a worldwide water crisis going on that we need to fight together by saving as much water as we can. The satellite will help researchers find more freshwater sources but we have to do our part by not wasting any water. </p>
<p>Do you think it’s important to save water? Please tell us in the comments section.</p>
