Two scientific satellites are being proposed by the Institute Nacional
de Pesquisas Espaciais (INPE). The first of them is being designed to
carry out about ten ionospheric, thermospheric, magnetospheric and as
trophysical experiments. Its orbit will be circular, inclined 25 degre
es with respect to the equatorial plane and 700 km of altitude. The sp
acecraft is to be launched by the Brazilian VLS rocket from the Brazil
ian equatorial launching facility Alcantara. Details on such a satelli
te program will be given in this presentation. The plans for the secon
