The primary camera used to film the Apollo 11 moon landing, capturing the iconic first steps and the subsequent exploration, was a specially modified Hasselblad 500EL Data Camera (HDC). This robust and reliable camera, paired with a Zeiss Biogon 60mm f/5.6 lens, proved instrumental in documenting one of humanity’s greatest achievements.
Understanding the Camera: A Deep Dive into the Hasselblad 500EL Data Camera
The choice of Hasselblad for the Apollo program was no accident. Their cameras had already proven their worth in the harsh conditions of space, utilized in earlier Gemini missions. However, the Apollo 11 mission demanded something more – a camera designed specifically for the lunar environment.
The HDC was not your average Hasselblad. Several crucial modifications were implemented to ensure its functionality and reliability on the Moon:
- Silvered Body: To minimize temperature fluctuations in the airless environment, the HDC’s body was silvered, reflecting sunlight and preventing overheating.
- No Leather Covering: The standard leather covering was removed to prevent outgassing in the vacuum of space, a process where materials release trapped gases, potentially contaminating sensitive equipment.
- Lubrication Modifications: Special lubricants, resistant to the extreme temperatures of the lunar surface, were used throughout the camera’s mechanical components.
- Reseau Plate: A glass plate with precisely etched crosses (reseau marks) was placed directly in front of the film plane. These marks appeared on the photographs, allowing for accurate measurements of distances and sizes within the images – a vital tool for scientific analysis.
- Film Magazine: Modified film magazines allowed for easy loading and unloading of the specially formulated 70mm Kodak film containing approximately 200 exposures per magazine.
The Biogon 60mm lens was selected for its wide-angle field of view, crucial for capturing expansive lunar landscapes and providing context to the astronauts’ activities. Its exceptional sharpness and minimal distortion also contributed to the clarity and scientific value of the images.
The camera was so integral to the mission that Commander Neil Armstrong had it attached to his chest. Thus, all images of Buzz Aldrin on the Moon were taken by Neil Armstrong with the Hasselblad 500EL Data Camera. He did not remove it during the moonwalk to take pictures of himself.
Beyond Still Photography: The Other Cameras of Apollo 11
While the Hasselblad 500EL Data Camera captured the iconic still images, other cameras played vital roles in documenting the mission:
- Westinghouse Color Television Camera: This camera, mounted on the Lunar Module (LM), transmitted the first live television images of humans on the Moon back to Earth. These grainy, black-and-white images, while not of high resolution, are etched in history as a testament to human ingenuity and perseverance.
- 16mm Data Acquisition Camera (DAC): Mounted inside the LM window, the DAC recorded time-lapse footage of the lunar landing and ascent. These films provided valuable data about the LM’s performance and the lunar surface conditions.
- Hasselblad Electric Camera (HEC): Several HECs were used both in space and back on Earth, used for Earth observation, documenting experiments and the crew in space.
These cameras, alongside the HDC, formed a comprehensive visual record of the Apollo 11 mission.
Frequently Asked Questions (FAQs) about the Moon Landing Camera
H3: 1. Why was Hasselblad chosen for the Apollo missions?
Hasselblad cameras were chosen due to their proven reliability, modular design, and high-quality optics. Their cameras had already been successfully used in previous space missions, demonstrating their ability to withstand the rigors of space travel. The modularity of the system allowed for easy modification to meet NASA’s specific requirements.
H3: 2. What happened to the Hasselblad camera left on the Moon?
To reduce weight for the return journey to Earth, the film magazines containing the exposed film were removed, and the Hasselblad 500EL Data Camera body was left on the Moon. The total weight of the cameras, film, and other supplies needed to be decreased, and the Hasselblad camera body was the most cost-effective way to do so. NASA deemed that the film was significantly more valuable to scientific research than the camera body.
H3: 3. What type of film was used in the Moon landing camera?
Kodak Ektachrome MS (ASA 160) 70mm film was primarily used for the color photographs taken on the lunar surface. This film offered a good balance of image quality, sensitivity, and resistance to cosmic radiation. A black and white film (Kodak Panatomic-X) was also used for certain scientific purposes.
H3: 4. How many pictures were taken on the Moon?
During the Apollo 11 mission, Neil Armstrong and Buzz Aldrin captured around 135 color photographs using the Hasselblad 500EL Data Camera. These images represent a small fraction of the total number of photographs taken throughout the entire Apollo program.
H3: 5. Did the lack of atmosphere affect the camera’s performance?
The lack of atmosphere actually aided the camera’s performance in several ways. The absence of atmospheric haze resulted in exceptionally clear and sharp images. Additionally, the vacuum of space helped to keep the lens clean and free of dust.
H3: 6. Was the camera difficult to operate in the bulky spacesuit?
Operating the camera while wearing the bulky Apollo spacesuit presented a significant challenge. The astronauts underwent extensive training to learn how to manipulate the camera’s controls effectively with their gloved hands. The design of the HDC was tailored to be as user-friendly as possible under these constraints.
H3: 7. How were the images protected from radiation on the Moon?
While the film was somewhat sensitive to radiation, the limited exposure time on the lunar surface and the protective design of the camera and film magazines minimized the potential for damage. The specially formulated film base provided a degree of shielding against cosmic radiation.
H3: 8. Were there any malfunctions with the camera during the Apollo 11 mission?
The Hasselblad 500EL Data Camera performed flawlessly during the Apollo 11 mission, a testament to its robust design and the rigorous testing it underwent before launch. There were no reported malfunctions that affected the quality or quantity of the photographs taken.
H3: 9. Could anyone purchase a similar Hasselblad camera at the time?
While the standard Hasselblad 500EL was available to the public, the modified HDC used on the Moon was a unique, custom-built version. The modifications, particularly the silvered body and the removal of the leather covering, were specific to NASA’s requirements and not offered commercially.
H3: 10. Where are the original Hasselblad photographs from the Apollo 11 mission stored?
The original Hasselblad photographs from the Apollo 11 mission, along with all the other Apollo mission photographs, are stored at the NASA Johnson Space Center in Houston, Texas. These images are carefully preserved and made available for scientific research and public viewing.
H3: 11. How have the Moon landing photos impacted photography?
The moon landing photos fundamentally changed photography in several ways: they demonstrated that the possibilities for cameras were only limited by your imagination and the materials available, rather than the laws of physics; they also showed the quality and sharpness possible with Hasselblad equipment, leading to a surge in popularity of their camera systems.
H3: 12. Are there any replica Hasselblad Moon Cameras available for purchase?
Yes, replica models of the Hasselblad used on the moon are produced by camera manufacturers. These replicas have become highly valuable collectors items.
