Lunar Day Fifteen
Tonight let’s begin our Moon walk adventures by talking about Luna 9, also known as Lunik 9 (Fig. 16.1). In 1966, the unmanned Soviet lunar probe became the first to achieve a soft landing on the Moon’s surface and successfully transmit photographs back to Earth. The lander weighed in at 99 kg, and the four petals, which formed the spacecraft, opened outward. Within 5 min of landing, antennae sprang to life and the television cameras began broadcasting back the first panoramic images of the surface of another world, proving that a landing would not simply sink into the lunar dust. Last contact with the spacecraft occurred just before midnight on February 6, 1966.
