The space mission PEGASE, proposed to CNES in the framework of its call for scientific proposals on "formation flying", is a 2-aperture interferometer, composed by 3 free flying satellites. With an angular resolution of a few mas and a spectral resolution of several tens in the spectral range 2.5-5 μm, PEGASE has several goals:
- science: spectroscopy of hot jupiters (Pegasides) and brown dwarves, exploration of the inner part of protoplanetary disks;
- technology: validation in real space conditions of formation flying, nulling and visibility interferometry concepts.
PEGASE, presently in 0-phase study takes place in the context of DARWIN preparation. We detail in this paper the present situation of this project
