Just as a reason for doing this in parallel. Space based detectors (such as LISA) are sensitive to a different frequency range than ground based detectors such as LIGO and thus to different of astrophysical phenomena [1] [1] http://www.ast.cam.ac.uk/~rhc26/sources/ http://www.ast.cam.ac.uk/~rhc26/sources/
