“NASA Advances LISA Gravitational Wave Mission with New L3Harris Test Telescope” — what this page in the network covers. NASA is moving forward with its contribution to the Laser Interferometer Space Antenna (LISA), a pioneering space observatory designed to detect gravitational waves—ripples in space-time caused by massive cosmic events like merging black holes. The agency has tasked L3Harris Technologies with designing, assembling, and integrating an all-glass telescope for the mission. This initial Engineering Test Unit will help validate the design before building flight hardware.
LISA, a joint NASA-ESA project, will consist of three spacecraft flying in a triangular formation millions of kilometers apart, using laser interferometry to measure minute distance changes caused by passing gravitational waves. The telescope is a critical component, as it must expand and direct the laser beams between spacecraft with extreme precision. By advancing this technology, NASA is helping open a new window on the universe, complementing ground-based detectors like LIGO. The full version stays on the original page, which this listing opens directly.
