50 years ago, what did people leave behind on the Moon?

In order to reduce fuel consumption for return flights, many accessories and cameras were left by astronauts on the surface of the Moon.

In addition to American flags and astronaut footprints, the Hasselblad 500EL camera is one of the first to be left after humans took the first photos on the Moon.

In the early days, the first cameras used by NASA Leica 1G had ultraviolet sensors to take UV photos or Ansco Autoset could take color pictures.

Later, NASA astronaut Wally Schirra proposed the use of Hasselblad 500C. This was the most technologically advanced camera then, proving the collaboration between Swedish photography company and NASA a few years before Apollo 13 was launched.

Hasselblad 500C is removed with viewfinder, reflective mirror, extra shutter and leather cover to be as light as possible. It is equipped with a 70-sheet film reel instead of 12 as the previous one.

After 500C, Apollo 11 equipped with two Hasselblad machines is 500EL Data Camera (HDC) and Electric Camera (HEC). HDC is used to capture the Moon's surface, equipped with a 60mm f / 5.6 Zeiss Biogon tube with a specially designed film roll that allows 200 times exposure on a 70 mm Kodak film.

Like the 500C, HDC is tuned to withstand the rigors of space. The machine uses silver paint to have a heat resistance range of -65 to 120 degrees C. A special glass plate is added to leave the "+" marks in the captured image, used to measure and collect the following data. this.

HDC was used by Neil Armstrong on the first human Lunar voyage. One of the most interesting photos is when Armstrong "selfie" through the reflection from astronaut Aldrin's hat, the far side is the image of the Earth reversed after the Moon horizon.

Hasselblads were not the only camera in the 1969 mission. There was also a Kodak camera that captures the Moon's background, two 16 mm Maurer cameras, and a camera mounted outside the spacecraft and camera. color television.

After an eight-day journey, the spacecraft weighing more than 45 tons when launched will return with a volume of nearly 5 tons. To reduce weight, the camera, lens and many accessories were left behind. Five Apollo missions then left a total of 12 Hasselblad cameras on the Moon's surface.

Hasselblad continued to work with NASA on subsequent Apollo missions, before the final Moon landing mission was carried out in 1972.

“It is one of Hasselblad's proudest achievements when it becomes part of the history of human space exploration,” said Dan Wang, Hasselblad's North American marketing director. Reciting 50 years of the first Moon landing made, we are happy to share our joy with the aerospace industry, as well as trusting our next generation adventurers. "
