LISA Pathfinder

The LISA Pathfinder “Einstein Geodesic Explorer”:  what we are (still) learning from the in-orbit measurement of differential acceleration

The LISA Pathfinder dataset – roughly 18 months of differential accelerations measurements plus a host of monitored environmental and dynamic variables – represents an experimental treasure that allows us to predict how LISA will work, understand how to improve LISA, and to indicate the right experimental tests to attempt on ground.

To date, we have published more than 20 articles on the LPF measurements, but we still have much more to learn from this precious Pathfinder – at least for free-falling test masses, we will never have a ground test bench for LISA that is as representative or as precise as LPF.

Our specific areas of analysis, completed and ongoing, include:
