Oldest photo of another planet’s surface
Pictured above is the oldest known photo of another planet’s surface. While it is blurry and difficult to see, it’s amazing that technology in the 1970s allowed humans to capture a clear image of another planet’s surface. Venera 9, was a Soviet uncrewed space mission to Venus. It consisted of an orbiter and a lander. It was launched on June 8, 1975, at 02:38:00 UTC and had a mass of 4,936 kilograms (10,882 lb). The orbiter was the first spacecraft to orbit Venus, while the lander was the first to return images from the surface of another planet.
The lander was encased in a spherical shell before landing to help protect it from the heat of entry as it slowed from 10.7 km/s to 150 m/s. This sphere was then separated with explosive bolts and a three-domed parachute was deployed which slowed the lander further to 50 m/s at an altitude of 63 km above the planet. It was the first spacecraft to return an image from the surface of another planet. Many of the instruments began working immediately after touchdown and the cameras were operational 2 minutes later. These instruments revealed a smooth surface with numerous stones. The lander measured a light level of 14,000 lux, similar to that of Earth in full daylight but no direct sunshine. They not only captured Venus for the first time, they’ll forever be known as supplying the world with the oldest image of another planet’s surface.
