Physicists at the Australian National University have created a tractor beam in water. Using a simple wave generator they can create water currents which could be used to confine oil spills, manipulate floating objects or explain rips at the beach.
WorldView-3, the world’s first multi-payload, super-spectral, high-resolution commercial satellite for earth observations and advanced geospatial solutions, will launch into orbit on Aug. 13 aboard an Atlas rocket. Operating at an expected altitude of 617 km, WorldView-3 will have an average revisit time of less than one day and will be capable of collecting up to 680,000 square kilometers of imagery per day. Its data-rich imagery will discover new sources of minerals and fuels, manage forests and farms, and accelerate DigitalGlobe’s exploitation of Geospatial Big Data™ – a living digital inventory of the surface of the earth.
