Neil Armstrong walked on the Moon in 1969.

Don Pettit isn’t one of the twelve astronauts that walked on the Moon.*

The reason they disagree with one another is the context of the question being asked or the conversation taking place.

The Apollo astronauts all landed during the lunar day.

The daylight period on the Moon lasts about 2 Earth weeks. So none of the moonwalkers were on the Moon during a lunar night. When they were on the Moon, they were in full sunlight. To see stars, they would need to adjust to night vision by standing in the shadow of the LM, and closing their eyes for a few minutes.

Then they’d need a way to block out reflected light from the lunar surface around them. Neil Armstrong spent about 2.5 hours on his EVA. Neil and Buzz worked from the moment they stepped on the regolith, until they returned to the LM. They didn’t have 5, 10, or 30 minutes to adjust for night vision.

They were there to study the lunar surface, not to do astronomy. From the moment they landed on the Moon, until the moment they launched back to lunar orbit was about 21 hours.

Don Pettit spent 369 days in space on 2 Space Shuttle missions and 2 ISS expeditions. He orbited the earth every 90 minutes, spending 45 minutes in daylight and 45 minutes in the shadow of the earth. As part of ISS missions, Don had time for personal activities and days off.

Even if he only had 1 day off each week, Don had 52 days off to spend on astrophotography or stargazing just for himself – and I’m sure part of his photography and observations were done during his work time.

The longest any Apollo mission spent in lunar space was 3 days.

* I point this out, not that Don doesn’t know what Neil’s experience was like, but usually hoaxers are extracting two different quotes out of context. That is, they aren’t both answering the same question, Neil’s quote is almost always from the post-flight press conference where he says that they couldn’t see stars on the surface.

Don’s quote is probably from an interview where he’s talking about his own experience – that is, talking about his time in space, when he could spend time on the night side of earth taking in the sights.
