Space observations offer many advantages for helio- and asteroseismology, due principally to the absence in space of transparency fluctuations, image blurring, and absorption by the Earth's atmosphere, and to the possibility of long-term continuous observations by a single spaceborne instrument. Helioseismology from space has already shown that stars produce a measurable oscillation signal through photometric variations at the micromagnitude level; this leads to the near-term possibility of simple spaceborne instruments for both helio- and asteroseismology. For the Sun, where photon flux is not a serious problem, doppler analyzer instruments also show great promise. A number of space investigations in helio- and asteroseismology presently under definition or development are briefly discussed.
