A flown Gemini 4 checklist used by astronaut Edward White on the first American spacewalk, in 1965, is among the lead lots of a major space memorabilia auction at Bonhams.
Valued at $80,000-120,000, the lot offers a phenomenal insight into one of the key milestones of the space race.
The Extravehicular Activity (EVA) is crucial to carrying out repairs and other maintenance while in orbit. The checklist indicates the steps needed to safely carry out the task.
The April 21 New York sale will also include a wealth of materials from the personal collection of Alan Bean, an astronaut who flew on the Apollo 12 mission in 1969.
Among the highlights are a framed set of pouches containing Bean's favourite meal (spaghetti).
It's accompanied by a letter of provenance that reads: "I hereby certify that the spoons and food were with me on my Apollo 12 mission.
"I wanted to be the first human to eat spaghetti on the moon as it was, and is my favorite food so I asked our food team to pack two first meals on the Moon for me. I ate one after Pete and I landed, and returned this same one back to Earth."
The unusual lot is valued at $50,000-80,000.
