Oceanus Procellarum

The Luna 13 spacecraft was launched toward the Moon from an earth-orbiting platform and accomplished a soft landing on December 24, 1966, in the Region of Oceanus Procellarum. The petal encasement of the spacecraft was opened, antennas were erected, and radio transmissions to Earth began 4 minutes after the landing. On December 25 and 26, 1966, the spacecraft television system transmitted panoramas of the nearby Lunar Landscape at different Sun angles and each panorama required approx. 100' to transmit. The spacecraft was equipped with a mechanical soil-measuring penetrometer, a dynamograph and a radiation densitometer for obtaining data on the mechanical/physical properties of the Lunar Surface as well as of and the cosmic-ray reflectivity.
Luna 13 transmitted 5 cycloramas over a period of 5/6 days.
It is believed that transmissions from the spacecraft ceased before the end of December 1966.
