Para quienes trabajan con relevamiento de suelos, bosques o inundaciones en la Argentina, esto significa mediciones más completas sin depender de piezas mecánicas que se mueven. Es una herramienta que podría llegar a mapear zonas remotas con mayor detalle, aunque todavía falta ver cómo se comporta fuera del laboratorio.","quienFirma":"Phys.org","confianza":"divulgacion","consulta":null},"sello":{"hash":"7ef0700de22234ec26bb38f32ecb690e5ba12937829acf7210ae63b5e3f0c381","sello":"5d3ad787eb394c47eccb0f11bfb9f2e1de1eaa6294ed8b97584da65dfe06f72d","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6572530,"aleatorio":"c980d93141d2950b55d8d6b3981a62aa88845ce2000f6a122f7cc7f6f699df67","tiempo":"2026-10-21T18:22:00.000Z"},"nist":{"cadena":2,"pulso":1993470,"salida":"366B53277FF77E5651F2B333AB469D60C20564B8DF0E2BE195EC2549F0C6495BE77A337B668CC4032541EFDBB0B033D10D8399BC0F39A7D9066AEE938DACE8A4","tiempo":"2026-10-21T18:21:00.000Z"},"noAntes":"2026-10-21T18:22:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 18:22:38 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"NASA's CASALS instrument bridges gaps in 3D maps of Earth's surface","descripcion":"A team of researchers at NASA's Goddard Space Flight Center (GSFC) has developed a new instrument designed to eliminate blind spots between lines of lidar data on Earth's surface. Built with support from NASA's Earth Science Technology Office (ESTO), the Concurrent Artificially-intelligent Spectrometry Lidar System (CASALS) could help researchers map the features of Earth's surface in detail. Rather than mechanically steering a laser with moving mirrors, CASALS steers light using wavelength itself, generating a continuous, 3D swath of the ground below.","pubDate":"Wed, 21 Oct 2026 14:20:09 EDT","url":"https://phys.org/news/2026-10-nasa-casals-instrument-bridges-gaps.html"},"indexado":"2026-10-21T18:21:56.795Z"}}
