A satellite tv for pc lifted off Friday from California on a mission to survey practically all our bodies of water on Earth, providing key insights on how they affect or are impacted by local weather change.
The Floor Water and Ocean Topography (SWOT) satellite tv for pc, a billion-dollar undertaking collectively developed by NASA and France’s house company CNES, took off at 1146 GMT atop a SpaceX rocket from the Vandenberg Area Drive Base.
In response to an announcement from NASA, it’s going to begin gathering scientific information in about six months after present process checks and calibrations.
“SWOT will deliver us a revolutionary advance in our understanding of how water strikes round our planet,” mentioned Karen St. Germain, NASA’s Earth Science Division director, forward of the launch.
“We can see element in eddies and currents and circulation within the oceans that now we have by no means been in a position to see earlier than.”
She mentioned this may assist predict floods in areas with an excessive amount of water, and handle water in areas liable to drought.
Selma Cherchali, of the French house company CNES, advised a press convention on Tuesday that the satellite tv for pc represents a “revolution in hydrology. We’re aiming to offer fine-scale observations ten instances higher than the present know-how.”
From a peak of 890 kilometers (550 miles), SWOT can have the clearest view but of the world’s oceans, permitting it to trace the rise in sea ranges, in addition to rivers and lakes.
Researchers will be capable of get information on tens of millions of lakes, reasonably than the few 1000’s at present seen from house.
“We all know with local weather change that Earth’s water cycle is accelerating. What this implies is that some areas have an excessive amount of water, others haven’t got sufficient,” mentioned Benjamin Hamlington, a NASA analysis scientist.
“We’re seeing extra excessive droughts, extra excessive floods, precipitation patterns are altering, changing into extra risky. So it is actually necessary that we attempt to perceive precisely what is occurring.”
The mission is supposed to final for 3 and a half years, however might be prolonged till 5 years, or much more, mentioned SWOT’s undertaking head at CNES, Thierry Lafon.
The US and French house businesses have labored collectively within the subject for greater than 30 years. A earlier satellite tv for pc developed by the companions, TOPEX/Poseidon, improved understanding of ocean circulation and its impact on world local weather.
