Historian Andy Saunders has sifted through 35,000 NASA images and spent the last few years remastering photos from the Apollo missions as a personal project, culminating in a book titled "Apollo Remastered" set to be released in celebration of the 50th anniversary of the lunar mission.
Commander Jim Irwin, seen above, was one of three astronauts who participated in what has been called the most scientifically intensive moon landing since mankind's arrival.

Apollo 15 was the first mission to deploy the Lunar Roving Vehicle. The LRV was a lightweight, electric vehicle designed to operate in the low-gravity vacuum of the Moon.

Saunders told CBS News that "the panoramic shots for Apollo 15 involve first 'remastering' each shot from the film and then aligning and stitching these together in digital processing software."

NASA's acting chief historian Dr. Brian Odom told CBS News that "Apollo 15 was a critical mission for the lunar program as it transitioned from a transportation paradigm to hardcore science."
Remastered photo of scientific collection
The Apollo 15 mission was focused primarily on scientific collection, with multiple spacewalks to collect lunar material. This included the famous Genesis Rock, which is 4 billion years old.

Odom: "Seeing historians like Andy [Saunders] dig into that mission and produce such cutting-edge results is incredible and speaks to the program's overall importance. Not only has Andy done a remarkable job bringing more details of this mission to light, but his incredible work has also created a lot of public excitement as NASA goes back to the Moon with the Artemis program."

Saunders: "The original NASA photographic film from the Apollo missions is some of the most important and valuable film in existence. It is securely stored in a freezer to maintain its condition... the film rarely leaves the freezer. The vast majority of Apollo images seen by the public over the last half-century have been copies of master-duplicates, or copies of copies, leading to the gradual degradation in the quality of the images we see."
Notations include the location of the lunar module and the Hadley Rille.
Before-and-after of the LRV's first tracks on the moon
Saunders says the original photos are "usually significantly under-exposed, and any significant gain/levels increase introduces a whole host of artifacts and glare from the scanning process. It's a time-consuming, painstaking process... but the reward is to see these incredible moments in history represented in unprecedented clarity."
