How long does it take for the cannon barrel to cool down after firing a shell ? Fernand Raynaud This quote is from a famous old French funny sketch by Fernand Raynaud, which was based on a question in a French manual for soldiers: the sketch is rather long, so I’ll give you the answer […]
Photovoltaic (PV) energy supplies more 20% of Spain’s total electricity, and this share hit a new high in July 2026 (28.3% of the nation’s monthly electricity mix). Some media outlets were concerned about the drop in photovoltaic power generation during the 12-Aug-2026 eclipse. Le Monde explained that « the drop is expected to be particularly pronounced […]
=> My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]
OpenAlex is a new, yet already very useful, open database for exploring scientific literature. For an upcoming blog post on the CNES Datacampus website, I analysed the proportion of papers that used only one of the Sentinel-2 or Landsat missions, as well as those that used both, in 2025. What struck me was that Sentinel-2 […]
Hello everyone, We have just created a mailing list for users of the IOTA2 software (iota2 — iota2 documentation). The tool will undergo significant developments in the coming months, and the purpose of this list is to communicate with the community to support these changes and to maintain the processing workflows needed by the users. […]
Pakistan news media reported that a glacier lake outburst flood (the failure of a dam containing a glacial lake) occurred near Gupis, Gilgit-Baltistan, a highly mountainous region administered by Pakistan. Satellite images show that the flood triggered a debris flow, which reached the Gupis valley where it hit the Roshan (Rashon) village and blocked the […]
After SMOS in 2009, and VENµS in 2017, the CESBIO laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]

The launch of Sentinel-2C (S2C) is scheduled on the 4th of September 2024, next week ! After 3 months of commissioning phase, S2C will replace S2A, to fulfill the Sentinel-2 mission together with S2B. S2B will later be replaced by S2D. The current plans are to keep S2A as a redundant satellite, in case something […]
