It comprised a bus with a mass of 1130 kg which held the descent probe. The probe was spherical with a mass of 405 kg and was designed for decelerations as high as 450-g. Venera 5 and 6 were designed with smaller parachutes (15 square meters) than Venera 4 to allow them to fall faster so as to get lower in the atmosphere while still operational.
