  ESA and NASA are studying projects having a tremendous return on variable
star research. Other national space agencies are also studying or developing
projects of smaller costs but with impressive returns. The projects range from
global Galactic surveys like the ESA mission GAIA which will give photometric
time series for about 1 billion stars, to detailed pulsation modes studies like
the CNES mission COROT which could reach a photometric precision lower than 1
ppm. The presentation will emphasize the future astrometric, asteroseismologic
and planet detection missions.
