Satellite imagery acquired by Sentinel-1C and Sentinel-2 provides a detailed view of the ports from which the Global Sumud Flotilla (https://globalsumudflotilla.org/) is scheduled to depart: Genoa (Italy), Barcelona (Spain), Tunis (Tunisia), and Sicily (Italy). The mission is organized in two phases: 31 August 2025: vessels will depart from Genoa and Barcelona. 4 September 2025: additional
Top of Atmosphere (TOA) Reflectance is a unitless measurement which provides the ratio of radiation reflected to the incident solar radiation on a given surface. It that can be computed from satellite measured spectral radiance using the mean solar spectral irradiance and the solar zenith angle. When comparing EO images from different sensors, there are two
Kamchatka is a peninsula located in the far east of Russia basically known for hosting a considerable number of glacier and stratovolcano, most of them with no activity in the last century. A stratovolcano is built up by many layers of hardened lava and volcanic ash characterized by periodic effusive and explosive eruptions. Around 300
Plymouth (GB), August 27th 1768: Lieutenant James Cook, commanding the British Royal Navy research vessel HM Bark Endeavour, raised anchor for his first journey of exploration of Terra Australis Incognita. The Endeavour, 30 metres long, brought the crew to Tahiti, 1769, to observe the transit of Venus across the Sun, and after to explore the unknown area of
The Proba-V 333m image of 03 March 2015 shows the Manicouagan crater, located in Manicouagan Region of Quebec, Canada. This lake represents one of the largest craters, roughly 100km, originating by an impact of a 5km diameter meteorite about 214 million years ago during the Triassic Period. In the middle of the lake, there is
In the middle of March mount Etna has been systematically erupting for several days. The first eruption has been recorded on Wednesday March 15th (11:30 am local time) and the activity has spread until a second outbreak on Saturday, with a series of pyroclastic flows, up to the next Monday (March 20th). A few persons got
A false-colour image of Italy, as seen in infrared by ESA’s Proba-V minisatellite, with vegetation shown in red, mountain area in red–brown and built-up areas as green. Proba-V is a miniaturized ESA satellite (launched on 7 May 2013) smaller than a cubic meter with the objective to map land cover and vegetation growth across the
Sentinel 3-A SLSTR thermal bands allow us to have an excerpt on the phenomenon of thermal inertia and heat transfer involving the land masses and oceans on our Planet. The thermal inertia is the propensity of heat to transfer between two different materials or bodies. Indeed each material has a different specific heat capacity (namely

After the huge icebergs disintegrated between July and August 2015, with its 582kmq, another iceberg breaks away from Pine Island This indicates that the melting of the Pine Island Glacier in Antarctica is accelerating in an irreversible process of major concern. This new iceberg is been captured by Earth observation satellites: Sentinels The two Sentinel
