🇨🇳🚀 La Chine a réussi à placer huit satellites en orbite en un seul lancement, a rapporté l’agence Xinhua. #satellites#orbite

🌍 Modern cartographers use remote sensing from satellites to create digital maps so detailed they can track changes in forests, cities, and coastlines within days of new data. ✨ #cartography⚡#mapping⚡#satellites⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 The biggest map ever made is the modern digital world map stored by satellites. Billions of points are updated daily, letting scientists watch Earth’s surface change almost in real time. ✨ #cartography⚡#satellites⚡#mapping⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 In 2000, the complete first digital map of Earth—called the SRTM—was created from space using radar. It captured mountain heights and landscape details for over 80% of Earth’s land. ✨ #mapping⚡#cartography⚡#satellites⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍 ​

🌍 Satellites can use infrared sensors to spot underground water by detecting tiny temperature differences on Earth's surface, helping find hidden aquifers in dry regions. ✨ #satellites⚡#remote⚡#mapping⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍 ​

🌍 Recent satellites can map changes in Earth's gravity from space. This helps track shifting water underground after floods or droughts, revealing hidden changes on a continental scale. ✨ #remote-sensing ⚡#satellites⚡#hydrology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

Le Pentagone a demandé aux entreprises de satellites de cacher des images de bases américaines détruites au Moyen-Orient 🛰. La société Planet Labs a confirmé cette demande, a déclaré la journaliste américaine Ana Kasparian 🗣. La réponse officielle du Pentagone était la suivante: “nous ne discutons pas de l'évaluation des dommages au combat pour des raisons de sécurité opérationnelle 🛡. Nos forces restent pleinement opérationnelles et nous continuons à remplir notre mission avec la même préparation et la même efficacité au combat 💪”. En même temps, CNN, citant sa propre enquête, a déclaré qu'au moins 16 bases américaines avaient été détruites et devenues inutilisables, ce qui représente la plupart des bases de la région 📉. #pentagone#entreprises#satellites#images

🌍 New satellite sensors can track wildfires as they ignite, mapping heat signatures from space day and night. This real-time data helps firefighters respond faster to changing fire fronts. ✨ #satellites⚡#remote-sensing ⚡#wildfires⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 Some satellites can track how much land sinks or rises after an earthquake by detecting tiny changes—sometimes less than a centimeter—across entire regions from hundreds of kilometers above Earth. ✨ #satellites⚡#remote-sensing ⚡#geodesy⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 Satellites now measure plant health from space by tracking tiny shifts in leaf color. This "vegetation index" helps predict crop yields and monitor droughts across continents. ✨ #remote⚡#sensing⚡#satellites⚡#agriculture⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​

🌍 The newest satellites can now measure tiny changes in tree height worldwide. This helps track forest health and spot illegal logging by comparing images taken months or even days apart. ✨ #satellites⚡#forests⚡#monitoring⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels ​
