The Venera 13 lander (left) with major systems noted (figure courtesy W. Huntress)—the GROZA-2 label points to the location of the loop antenna mounted externally just above the shock-absorbing landing ring. The disk structure near the top stabilized the probe during descent after the parachute was released. The GROZA-1 instrument is shown at the right (figure courtesy L. Ksanfomality) showing the loop antenna and mounting strut, together with a microphone for detecting thunder—note the heavy-duty insulation on the cable to protect it from the hot corrosive Venus atmosphere
