NASA to conduct first global water survey from space
A NASA-led international satellite mission was set for blastoff from Southern California early on Thursday on a major Earth science project to conduct a comprehensive survey of the world’s oceans, lakes and rivers for the first time, Reuters reported.
Dubbed SWOT, short for Surface Water and Ocean Topography, the advanced radar satellite is designed to give scientists an unprecedented view of the life-giving fluid covering 70 percent of the planet, shedding new light on the mechanics and consequences of climate change, the article went on to explain.
A Falcon 9 rocket, owned and operated by billionaire Elon Musk’s commercial launch company SpaceX, was set to lift off before dawn on Thursday from the Vandenberg US Space Force Base, about 275 km northwest of Los Angeles, to carry SWOT into orbit.
If all goes as planned, the SUV-sized satellite will produce research data within several months.
Nearly 20 years in development, SWOT incorporates advanced microwave radar technology that scientists say will collect height-surface measurements of oceans, lakes, reservoirs and rivers in high-definition detail over 90 percent of the globe.
The data, compiled from radar sweeps of the planet at least twice every 21 days, will enhance ocean-circulation models, bolster weather and climate forecasts and aid in managing scarce freshwater supplies in drought-stricken regions, according to researchers.
