NASA Successfully Tests CASALS Airborne Prototype to Create Continuous 3D Maps of Earth’s Surface

From orbit, today’s space-based laser instruments measure Earth’s forests and terrain one narrow line at a time. Between those lines are enormous gaps that include millions of acres of land scientists never directly measure. NASA’s CASALS instrument will blend machine learning with an ultra-compact lidar instrument to adaptively ‘sweep’ large swaths of Earth’s surface. This […]

NASA Engineers Streamline Rocket Vibration and Shock Analysis Using New Commercial Software Workflow

Editorial illustration for NASA Engineers Streamline Rocket Vibration and Shock Analysis Using New Commercial Software Workflow

Rockets vibrate, shake, and flex intensely as they climb into space, and spacecraft packed with delicate scientific instruments must survive those forces. Before any rocket leaves the ground, NASA engineers work to predict how those stresses will affect every part of a spacecraft. To do that, engineers in the Dynamic Environments Group with NASA’s Launch […]

NASA Tasks L3Harris Technologies With Building Final Test Telescope for the LISA Gravitational Wave Mission

NASA has taken the next step in the process of developing a new all-glass telescope for the LISA (Laser Interferometer Space Antenna) mission, a space observatory designed to detect ripples in space-time called gravitational waves. L3Harris Technologies will design, assemble, and integrate the new telescope for NASA. Called the Engineering Test Unit, this contribution represents […]
