Abstract We outline the main features and capabilities of several space astrometric projects approved or currently under review. The most ambitious aim at microarcsecond accuracy in absolute astrometry. Relativistic deflection of light will be detectable in the irregular displacement of a distant star nearly aligned with a massive deflector. Likewise in some instances measurements of star diameters will have to be interpreted by including relativistic effects.
