SACI-2

The satellite weighed approximately 80 kg. It was a box approximately 60 cm long and 40 cm square, with a circular base plate and surrounded by a metal ring, both about 80 cm in diameter. Besides being a technology testbed, it carried four scientific payloads (PLASMEX, MAGNEX, OCRAS, and PHOTO), with a total weight of 10 kg, to investigate plasma bubbles in the geomagnetic field, airglow, and anomalous cosmic radiation fluxes. It was meant to circle the Earth on a circular orbit at 750 km altitude, inclined 17.5 ° from the Equator.
