MPI for Gravitational Physics🎂 Ten years ago on this day, LISA Pathfinder (LPF) was launched into space 🚀
There was a public launch event at @mpi_grav in Hannover, starting at 4:35 a.m.: https://www.aei.mpg.de/201933/public-event-for-lisa-pathfinder-launch.
Fortunately, after a brief hiccup in the ESA livestream immediately after liftoff, everything went smoothly.
LPF was the European Space Agency's (ESA) test mission for LISA, the first gravitational-wave observatory in space. LPF spectacularly and very successfully demonstrated that LISA's key technologies work.
