    Mapping the Causes of Mangrove Loss

    Lurker
    By Lurker,
    A joint NASA-USGS initiative has created the first worldwide map of the causes of change in mangrove habitats between 2000 and 2016. Mangrove trees can be found growing in the salty mud along the Earth’s tropical and subtropical coastlines. Mangroves are vital to aquatic ecosystems due to their ability to prevent soil erosion and store carbon. Mangroves also provide critical habitat to multiple marine species such as algae, barnacles, oysters, sponges, shrimp, crabs, and lobsters. Mangroves

    SkySats 19-21 to Launch on SpaceX Falcon 9 Rideshare Mission

    By Lurker,
    Planet is set to launch three more new SkySats (SkySats 19-21) into Low Earth Orbit on August 18th (date subject to change), rounding out the fleet of SkySats already in operations and joining SkySats 16-18 that successfully launched aboard the SpaceX Falcon 9 in June. Planet SkySats 1-15 operate in Sun Synchronous Orbits, a specific type of Low Earth Orbit that results in the Earth’s surface always being illuminated by the Sun at the same angle when the satellite is capturing imagery.

    NASA Advanced Rapid Imaging Satellite Maps Blast Damage: Beirut Explosion Aftermath

    Lurker
    By Lurker,
    NASA’s ARIA team, in collaboration with the Earth Observatory of Singapore, used satellite data to map the extent of likely damage following a massive explosion in Beirut. Dark red pixels represent the most severe damage. Areas in orange are moderately damaged, and areas in yellow are likely to have sustained somewhat less damage. Each colored pixel represents an area of 30 meters (33 yards). The map contains modified Copernicus Sentinel data processed by ESA (European Space Agency) and analyzed

    The video shows a landslide analysis of Tersun Dam simulated with FLOW-3D. For more examples of how FLOW-3D can be used to analyze the catastrophic events. A fully 3D simulation was performed in the vicinity of the breach to capture the complex 3D hydraulic conditions. https://www.youtube.com/watch?time_continue=3&v=f9QzOn0vxpc&feature=emb_title
