LISA Pathfinder Launches

The LISA Pathfinder spacecraft launched a few days. While the LISA Pathfinder won’t be making serious physics measurements, it will be testing new technologies that are expected to be used in the final LISA experiment. LISA is planned to be an orbital gravitational wave experiment, similar to LIGO but in space and with a much longer arm distance. It will be sensitive to different types of gravitational waves than LIGO.
