Question about communication delay time with the Nixon Apollo call

When Nixon called the moon there were sometimes upwards of 7 seconds in delay.  One of my colleagues thinks that is a technical delay, while I believe that it is a combination of technical and then human delay.  

From what I've always been told, the technical delay would be around 3 seconds.  ~2.5 for the radio wave to propagate there and back and then ~5 seconds for the transmission between Nixon/Houston/Australia.  Meaning the rest of the delay is just the human part of hearing the message, understanding it, thinking of response, etc. 

Does anyone have some insight on this and some citation?

Apollo spoon rest?

Cleaning out the grandmother's hoarder house and found what looks like a spoon rest. Any clues if this was sold in souvenir shops as official merchandise or more likely a random little shop?

Why didn’t they make the CSM already docked properly to the LM at launch?

This seems like a bit of a silly question but my father and I are watching the Apollo 11 documentary on Netflix and they just covered the part where the two craft separated and docked together while traveling to the moon and it seemed odd to us that that was necessary to the mission. Thanks for any answers!

Photo book

The recent Artemis mission has made me wonder more about this book. My mom was a space nerd in the 70s and she bought this book of photos of/from the Apollo missions. It was made (published?) by Meisel Photochrome and has 20 images printed on Kodak photo paper. From what I understand they were made from original negatives from the Apollo missions. I have found very little information about it online. I found one forum from 2012 where someone else had one and one auction from a few years ago where one was sold. I have also seen sites with the same images, also from Meisel, but individually framed. I included one pic of the cover and spine and one of the well known photos. The cover has a few grime spots that could probably be wiped off but is otherwise in great condition. The photos within are still in pristine condition. If anyone has any information about this book I would love to know more.

Saturn V vs Space Shuttle vs SLS

The story of the three machines that made the journey to space possible for 60 years:

Saturn V, the rocket that took humanity to the Moon and was never truly surpassed.

The Space Shuttle, the workhorse that built our presence in orbit over thirty years.

And SLS, the Space Launch System that carried the engines of the Shuttle and the ambitions of Apollo, all the way back to the Moon.

Got sent to Mission Control for work by our commander who was a former astronaut. Was there the day after the 40th anniversary of the first moon landing so we got to visit the Apollo command floor.

The mirror is off Apollo 13 and was put on a dedication plaque by the crew as a thank you to the controllers for getting them back home safely. The flag flew around the moon on Apollo X and there is a copy of the plaque they left on the moon. Sorry for the photo quality. It was taken on my 2009 flip potato.

Gene Kranz - An Inspiration

For the last 20+ years I’ve worked in the Nuclear Industry as a Reactor Operator and latterly a Simulator Instructor. I incorporated Apollo 11 and 13 into some decision making training. Gene has always been a huge hero of mine. In 2021 the station ended generation.

I wrote to Gene to let him know that he had played a part in that story. I didn’t expect a response but I received something a few weeks later.

"Hope Eyrie" - a psalm for Apollo 11 (2026 re-release)

In 1976, Leslie Fish wrote a fairly remarkable anthem to celebrate the Apollo 11 landing, "Hope Eyrie".

(At least, 'remarkable' is the word that Dr. Roger Launius, formerly NASA's chief historian, used to describe it. He also wrote about this song in his 2005 paper, "Perceptions of Apollo: Myth, nostalgia, memory or all of the above?”, as well as in his other writing.)

Although Leslie has sadly now passed away, I wanted to share a new, labor-of-love recording of this song (using a decades-old vocal recording), that about 20 of us have been working to bring to life over the past year.

The producer is Michael Moricz (who was the final music director for PBS's Mister Rogers' Neighborhood.)
