The last 24 months did not only see the first direct detection of gravitational waves by LIGO but also the successful launch and operation of the LISA Pathfinder (LPF) mission. While the LIGO detection sparked the scientific and public interest in these 'mysterious' waves, the LPF results show that a space-based gravitational wave observatory is within reach. This Laser Interferometer Space Antenna (LISA) has the goal to detect the infrasound of the universe over five decades in frequency centered around a few mHz. Expected sources range from hundred thousand compact galactic binaries to extreme mass ratio inspirals out to redshifts up to 2 to massive and supermassive black hole mergers in the million to hundred million solar mass mass range out to redshifts of 20. LIGO sources years before the merger have recently been added to LISA's source catalogue. LISA will use free falling cubic test masses as the end points of their 2.5 Gm long interferometer arms. As shown by LPF, these test masses follow their geodesics with spurious accelerations below a femto-g/√Hz. LISA will use laser interferometry to measure distance changes between the test masses at the few pm √Hz level. ESA is leading the LISA project and NASA is exploring how to participate as a minority partner. LISA is ESA's L3 mission with an expected launch in the early 2030s. I will discuss LISA's payload and also the schedule of the LISA mission.
