As ESA and China mark a decade of cooperation, imagery over China’s Poyang lake is testament to the new Sentinel satellite’s promise of continued radar data acquisition for a multitude of applications.
Down on the ground, death equals stillness – but not in space. Derelict satellites can tumble in unpredictable ways and ESA’s team tasked with developing a space salvage mission want to find out why.
A new paper from physics students at the University of Leicester explores the possibility that an observational satellite that lost contact with Earth in 2012 could be the catalyst that sets off a chain of events much like those depicted in the Academy Award-nominated film Gravity.
Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.
According to a new study from the European Space Agency, ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar images in the study show how shifts in our climate are affecting high-latitude regions.
With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well.
Building on its use of satellites for responding to disasters, ESA has helped to create a service that makes flood maps available simply via the Internet.
An ESA report says satellite observations indicate that carbon dioxide in our atmosphere continues to increase, despite global efforts to curb emissions.
NASA mission controllers recently lost contact with the Jason-1 satellite, and the space agency has decided to abandon this satellite and focus attention on the other two satellites currently orbiting Earth.

- A village protected by such a structure.
