A SpaceX Falcon 9 rocket launched a $1.2 billion satellite to monitor Earth's oceans, rivers and lakes with a high-power radar and other sensitive instruments to better assess the movement of the planet's water and the impacts of climate change.
A SpaceX Falcon 9 rocket launched a $1.2 billion satellite early Friday to monitor Earth's oceans, rivers and lakes with a high-power radar and other sensitive instruments to better assess the movement of the planet's water and the impacts of climate change.
A SpaceX Falcon 9 rocket climbs away from launch complex 4E at Vandenberg Space Force Base in California carrying a $1.2 billion satellite designed to monitor water levels across the planet, helping scientists learn more about the effects of climate change.The satellite is designed to measure the height of water across 70% of the planet every three weeks, generating a terabyte of data per day.
That means many areas that are wet are getting wetter, she said, and areas that are dry are getting drier. The mission began at 6:46 a.m. EST when the Falcon 9 rocket's first stage engines thundered to life with a rushing jet of flaming exhaust, lighting up the pre-dawn sky as the booster climbed away from Vandenberg Space Force Base northwest of Los Angeles.
After two firings of the second stage engine, SWOT was released in a 530-mile-high orbit carrying it around the planet 14 times a day, passing over every point on Earth between 78 degrees north and south latitude. Another instrument, an Earth-facing altimeter, will measure water height directly below the SWOT spacecraft and a microwave radiometer will collect data allowing scientists to correct for the effects of water vapor, which affects the propagation of radar beams.
