The Scientific Programme Committee (SPC) of the European Space Agency (ESA) today adopted the LISA and EnVision missions. These are respectively the most important space observatory for gravitational waves and a probe that will study the many mysteries still hidden on the planet Venus. The two missions see strong Italian participation with the Italian Space Agency (AS), the National Institute for Nuclear Physics and the University of Trento. The study phase of the two projects has therefore been completed and ESA is now committed to implementing the missions: LISA will be launched in the mid-2030s while EnVision's departure to Venus is currently scheduled for 2031.
