Called SWOT, the satellite will perform a comprehensive survey of Earth's water levels—something no satellite has ever attempted before.

Rest assured that PIA’s virtual private network never keeps any usage logs—ever.SWOT is equipped with a radar instrument named Ka-band Radar Interferometer, or KaRIn for short, which is designed to survey at least 90% of the Earth’s surface and measure water height.
The satellite will operate in a non-Sun synchronous orbit, which means it will pass over the same area of Earth at the same mean solar time. Its orbit will be at an altitude just over 554 miles , from where it will survey Earth’s surface water at least twice every 21 days. SWOT will send back about one terabyte of unprocessed data everyday,The mission is designed to operate for at least three years.
“SWOT will provide vital information, given the urgent challenges posed by climate change and sea level rise,” Laurie Leshin, NASA’s Jet Propulsion Laboratory director, said in the NASA statement. “That SWOT will fill gaps in our knowledge and inform future action is the direct result of commitment, innovation, and collaboration going back many years.”
