We describe a stellar seismology photometric experiment which we have proposed to embark on-board the interplanetary vehicles belonging to the VESTA mission (France - USSR mission towards Mars and the asteroids belt, to be launched about 1994). The objective is to use the cruise time to obtain long, uninterrupted observations of the white light fluctuations in a few late-type stars, with a view to the detection of global non-radial modes at the level 10−5 to 10−6 mag. We have performed a design-study of the instrumentation, formed by a 5 cm spherical collector, working in two spectral bands 1500 A wide, with two photomultipliers as detectors. Advantages and difficulties of the system are briefly discussed.
