NASA and CNES (French Space Agency) are collaborating to make the first global survey of Earth’s surface fresh water and study fine-scale ocean currents with a new mission called SWOT, or Surface Water and Ocean Topography. SWOT will collect data on the height of Earth’s salt and fresh water – including oceans, lakes, and rivers – enabling researchers to track the location of water over time, which will help measure the effects of climate change. SWOT is expected to launch from Vandenberg Space Force Base in central California in November 2022.
SWOT is a collaboration between NASA and the French space agency Centre National d’Etudes Spatial (CNES), with contributions from the Canadian Space Agency (CSA) and United Kingdom Space Agency (UK Space Agency).
A new satellite that will track water levels on Earth is scheduled to launch tomorrow morning.
The satellite is called the Surface Water and Ocean Topography, or SWOT. As climate change impacts the planet’s water supply, the satellite can provide high-definition data to scientists.
“So as SWOT helps us understand the detailed changes in the water cycle, that’ll help us better predict or project what communities might face. And that’s going to help communities prepare for the changes,” Karen St. Germain, NASA Earth Science Division Director, explained.
SWOT has been jointly developed and managed by NASA and the French space agency Centre National d’Études (CNES), with contributions from the Canadian Space Agency and UK Space Agency.

“SWOT is going to be able to track water throughout the entire watercycle,” Germain explained. “As water moves from the oceans, through the atmosphere, onto land and back, [SWOT will provide] 10 times better spatial resolution — or fidelity or clarity — than we’ve ever had before.
Using data from NASA’s Hubble and Spitzer Space Telescopes, astronomers have found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a large fraction of the entire planet.
A SpaceX Falcon 9 rocket launches NASA’s new SWOT satellite, (SWOT is short for Surface Water and Ocean Topography), an international mission designed to conduct the world’s first comprehensive survey of Earth’s water surfaces, from oceans to lakes and rivers.
To investigate humans’ impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth’s lakes and reservoirs – including ones previously too small to measure from space. Scientists used these height measurements to study 227,386 water bodies over 22 months and discovered that, from season to season, the water level in Earth’s lakes and ponds fluctuate on average by about 8.6 inches (0.22 m). At the same time, the water level of human-managed reservoirs fluctuate on average by nearly quadruple that amount – about 34 inches (0.86 m).
The American space agency Nasa has launched a satellite that’s expected to transform our view of water on Earth. The Swot mission will map the precise height of rivers, reservoirs and lakes, and track ocean surface features at unprecedented scales. It should improve flood and drought forecasts, and help researchers better understand how the climate is changing.
A NASA-led international satellite mission has been designed to conduct the first global survey of the Earth’s surface waters, helping shed new light on the mechanics and consequences of climate change.
The great Maria Callas performs an aria from her signature role, Bellini’s druid priestess Norma, with the Orchestre de l’Opera National de Paris and Georges Sebastian. Recorded live at the Palais Garnier on the 19th of December 1958, this concert marked the soprano’s debut at the Paris Opera, a major social event for Parisians and for which Callas donned her most elegant couture and a million dollars’ worth of jewelry.
This Holiday and Christmas season we bring you this uplifting version of Sleigh Ride by Leroy Anderson. This version of Sleigh Ride was performed by Boston Youth Symphony Orchestras featuring students from the Repertory Orchestra in December of 2020. May this performance of Sleigh Ride bring you a moment of happiness this season!

Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
