The first space seismological experiment, EVRIS (Baglin 1991) will be launched in 1996 and will observe ∼ 10 stars over ∼ 20 days each. A second one, COROT (Catala et al., 1994), should follow soon after (1999-2000), which should monitore ∼ 5 stars over ∼ 5 months each. The observed stars will be main sequence stars. For an optimum scientific outcome of EVRIS mission, one must select the best possible target stars. The first step of this selection is outlined. What would be further gained with COROT project is discussed.

Specifications of both missions imply that among possible target stars, δ Scuti stars should present a large number of self excited modes, likely many more than presently observed from ground based networks.
