Sentinel-2C satellite delivers first breathtaking images of Earth: Sentinel-2C, the latest satellite in the Copernicus program, has captured its first stunning images of Earth. #Sentinel2CSatellite #Sentinel2C #Satellite #ImagesOfEarth #ImageOfEarth #EarthImages #CopernicusProgram #HighResolutionImages #EnvironmentalMonitoring #ESA #DisasterManagement #EarthDotCom #EarthSnap #Earth

🚀 In a recent post, we looked at how the ESMERALDA-TRACKER platform leverages the successful Copernicus programme, commissioned by the European Commission and managed by the European Space Agency (ESA). Its Sentinel satellites collect high temporal and spatial resolution data, which are available to everyone for free!🌍 🛰️ These satellites measure the electromagnetic spectrum, part of which is visible to the human eye. When the sun shines on the Earth, this radiation is reflected back, allowing multispectral optical sensors to collect images passively. In contrast, RADAR satellites use their own energy source, emitting radiation that bounces back from the Earth, making this active process largely unaffected by clouds. It is similar to how dolphins and bats hunt, if you are more familiar with that. More details here: [here](https://lnkd.in/gJ9tnXN). Sentinel-1, like its counterparts, will fly as a pair in the same orbit but 180° apart, providing high temporal resolution with a revisit time of about 5 days for any point on Earth. Sentinel-1 sends out microwave signals that reflect off the Earth's surface to gather specific information. 🌲🏙️🏞️ Here's how  ESMERALDA-TRACKER utilizes this data: 1. Users draw a bounding box on the map to mark the area of interest and choose two image acquisition dates. 2.  ESMERALDA-TRACKER accesses the Sentinel-1 archive and retrieves the relevant satellite scenes. 3. These scenes are processed by actinia, our open-source geoprocessing engine based on GRASS GIS. 4. The final map is delivered for visual inspection, further calculations, or export. Interpreting these maps can be quite tricky, but in ESMERALDA-TRACKER we have tried to make it as easy as possible: pink means signal loss and green means signal gain. In tropical rainforests, pink areas indicate forest loss, while green areas indicate (re)growth. #SatelliteData #RemoteSensing #GIS #EarthObservation #Copernicus #HERMOSA #Sentinel1 #EnvironmentalMonitoring Alain Retiere Hinrich Paulsen 🇪🇺 Jürgen Ackermann Markus Neteler Michel Ackermann Nicolas Ackermann Philippe GISQUET Oliver Herrmann Xenia Paulsen

What is Satellite Remote Sensing? How we gather data from space? Satellite remote sensing allows us to observe Earth from above, capturing data across oceans, forests, cities, and even the atmosphere. Foundations: Platform & Sensor – Satellites carry specialized sensors to detect various data. Spectral Bands & Resolution – Different bands reveal different insights, like tracking vegetation or mapping urban areas. Types of Satellites: Ocean Observation Terrestrial Observation Atmospheric Observation Situational Awareness Sensor Types: Active (works day/night) Passive (relies on sunlight) Applications: Natural Resource Management, Hazard Assessment, Ocean & Coastal Monitoring, Agriculture, Urban Planning, and more! 👉 If this post helped you understand Remote Sensing Satellites, feel free to repost and share the knowledge!

Satellites Constellation for Earth Observation

🛰️ Explosion of Intelsat 33e Satellite Poses Long-Term Threat in Geostationary Orbit The recent breakup of Intelsat 33e has intensified concerns around debris management in geostationary orbit (GEO), a vital region 22,000 miles above Earth. An animation released by COMSPOC, a space situational awareness firm, illustrates the spread of over 500 fragments following the Oct. 19 incident. GEO’s unique position allows satellites to stay over a fixed spot, supporting key operations like broadcasting and weather monitoring. However, this explosion now poses risks across this orbital ring, increasing the likelihood of collisions with other satellites, says COMSPOC’s chief scientist Dan Oltrogge. The animation, shared on social media, visualizes the pink cloud of debris fragments expanding rapidly among green dots representing active satellites. With such widespread impact, tracking every fragment will take time. Only the larger pieces can currently be mapped and avoided by satellite operators; smaller fragments, however, evade detection due to their distance and could strike other satellites unexpectedly. This risk compels operators to monitor any sudden, anomalous behaviors in their satellites as potential signs of untrackable debris impacts. Unlike lower Earth orbits, where residual atmospheric drag helps clear debris, GEO lacks such natural clearance, meaning debris here will persist indefinitely. The lingering fragments will likely oscillate near a gravitational concentration at 75 degrees east, where they pose continued threats to GEO satellites. While sustainability efforts have mostly focused on crowded low Earth orbits (LEO), where many observation and communication satellites operate, this incident underscores GEO's susceptibility to long-term risks. Intelsat 33e, built by Boeing and launched in 2016, was expected to serve up to 20 years, but past propulsion issues had already reduced its lifespan. Boeing is currently investigating the root cause of the explosion. With GEO debris expected to remain indefinitely, Oltrogge emphasizes the importance of accurate and proactive strategies to mitigate these new risks, especially in this valuable but fragile region.  #SpaceDebris #GeostationaryOrbit #Intelsat33e #SatelliteSafety #SpaceSustainability

As we witness the rapid evolution of space technology and the burgeoning satellite industry, the management of space traffic has become an increasingly critical concern. With the recent acquisition of geospatial intelligence firm Orbital Insight by Privateer, a startup focused on satellite-tracking software, we are witnessing a convergence that could have profound implications for space traffic management and situational awareness. The integration of Orbital Insight's TerraScope Earth observation platform with Privateer's satellite-tracking software represents a significant step towards enhancing our ability to monitor and manage space traffic. This amalgamation of capabilities underscores the importance of end-to-end vertical integration and cross-functionality in addressing the challenges posed by the exponential increase in satellite launches and the proliferation of space debris. However, while technological advancements are crucial, they must be accompanied by a robust regulatory framework to ensure the responsible and sustainable use of space. The growing threat of space debris, which poses significant risks to satellite operations and space exploration, underscores the need for a normative order for space traffic management. To address this challenge, we must embrace innovative solutions that leverage advanced technologies and collaborative approaches. One such solution could involve the development of autonomous systems capable of real-time monitoring and collision avoidance, coupled with predictive analytics to anticipate and mitigate potential threats. Furthermore, establishing clear liability clauses and accountability mechanisms will be essential for incentivizing responsible behavior among spacefaring nations and commercial entities. This could involve the creation of an international framework for space governance, akin to existing norms in air traffic management and environmental protection.
