"European Mission Receives Approval to Detect Cosmic Ripples"

The European Space Agency has approved the ambitious and expensive Lisa mission, which aims to detect gravitational waves by using three spacecraft firing lasers at each other over a distance of 2.5 million km. The mission, with a budget of €1.75bn, will involve contributions from several European countries and the US. Lisa will study the collisions of supermassive black holes, providing insights into the nature of space-time and the evolution of galaxies. The mission is not expected to launch before 2035 and will require astonishing measurement precision due to the tiny signals from gravitational waves.
