LISA Mission: Pioneering Space-Based Gravitational Wave Observatory to Probe the Universe's Most Powerful Events

The Laser Interferometer Space Antenna (LISA) mission is set to become the first space-based observatory dedicated to the study of gravitational waves. These ripples in space-time, generated by events such as merging black holes, will allow LISA to probe the universe's history. Unlike ground-based observatories like LIGO and Virgo, which are limited to high-frequency gravitational waves, LISA will scan the entire universe for waves across a broad range of frequencies. Comprising three spacecraft in a triangular formation millions of kilometers apart, LISA will orbit the Sun, trailing Earth by 50 million kilometers. It will detect gravitational waves by measuring subtle changes in the distances between free-floating cubes within each spacecraft, using laser interferometry. LISA aims to study the nature of gravity, observe the dynamic cosmos, and expand our cosmic horizon to epochs before the formation of stars and galaxies.
