10th anniversary of the launch of LISA Pathfinder

[December 3rd 2025] Today, we commemorate the tenth anniversary of the launch of the LISA Pathfinder (LPF) mission. This milestone was a moment of deep pride for the entire LISA Community and the thousands of people who contributed to this extraordinary feat of engineering and science.

LISA Pathfinder was an extremely successful mission that demonstrated our ability to go above and beyond the key technological requirements for the future LISA mission. LPF successfully measured and controlled the motion of the test masses in space with unprecedented precision, effectively removing one of the main technological risks and paving the way for LISA to become reality.

The success of LPF is a testament to the dedication of its international team. This was a scientifically, technologically, and organizationally demanding project whose success created the essential conditions that now enable us to realize the revolutionary potential of LISA.

We are now half way between the launch of LPF and the nominal launch date of the LISA. Looking to the next decade one of our key responsibilities is to ensure the knowledge and expertise developed through the LPF project are passed on to the next generation of scientists and engineers.
