Gravitational wave astronomy in space, that is the goal of the LISA Collaboration.  LISA stands for Laser Interferometer Space Antenna.  This collaboration is having a very early meeting in Florida and at that meeting there will be certain public talks broadcast on YouTube.  I will embed those here. With perhaps a translation for the perplexed later.  

If you find gravitational wave astronomy i.e. as done by the LIGO collaboration interesting, then you will love what LISA will do. 

The Gravitational Wave Astronomical Revolution

Presented by Public Talk by Dr. David Reitze Executive Director of the LIGO Laboratory, Caltech Professor at the University of Florida.
