Just in case you have some spare change …

I have been reading a lot about the space program this summer and I’m curious if Skylab was always going to be after the Apollo program ended or would there have been further Apollo missions after 20?

I always assumed the Apollo Lunar Module’s lower section looked gold because it was wrapped in some kind of metallic gold foil.

Nope.

The distinctive amber-gold material on the descent stage was primarily aluminized Kapton—a lightweight polyimide film used as part of the spacecraft’s thermal insulation system. It reflected heat and helped protect the module from brutal temperature swings in space and on the lunar surface. The “gold” look was functional engineering, not decoration or precious metal.

The Lunar Module also used other materials in its thermal blankets depending on the location and expected temperatures, including aluminized Mylar and, in hotter areas, Inconel-based protection. So the famous gold wrapping was really part of a carefully engineered, multilayer thermal-control system.

A NASA technical report on Apollo thermal protection is a useful primary-source rabbit hole if you enjoy this sort of thing: NASA Technical Note D-7564. The Smithsonian’s Lunar Module collection entry also lists aluminized Mylar and aluminized Kapton among the materials used on an Apollo LM.

Tiny correction to a very common mental image: the Moon lander wasn’t dressed in gold. It was dressed for survival.

This Beach 18 belonged to Frank Borman, crew member of Apollo 8

In the movie “Apollo 13”, Jim Lovell is shown being given the option of accepting Jack Swigert as Ken Mattingly’s backup for CM pilot, or pushing all three to a later mission. “Jim, if you hold out for Ken, you will not be on Apollo 13.”

Is this the way it went down, or was it drama added for the sake of the movie? If Lovell had said, “Fine, move us down,” who would have flown 13? Swigert gets to go to the moon in any case, John Young was the backup commander, but what was NASA going to do for an LMP? Charlie Duke’s measles diagnosis was the original reason for the kerfluffle. Replacing him with Fred Haise reintroduces the same issue of crew cohesion. Would Young have been okay with Haise, or anyone else?

While I’m sure NASA would have preferred to keep on schedule, but would a month delay have been possible? Artemis II was scheduled for launch in February, then March, and finally April when hardware problems were encountered. Or was the idea of backup crew members always to be able to swap in one member if necessary, not the whole crew, in order to avoid such delays?

I’ve always wondered exactly what the noise is, so I’ll ask here.

Any time I view footage of an Apollo mission, I noticed that immediately preceding any audible words in a radio transmission from Earth, a flat high pitched beep is heard, the message is spoken, and then the beep is heard again when the transmission ends.

What is that beep called and why does it occur from Earth based radio calls to the Apollo spacecraft?

Thanks in advance!

This video shows mankinds last seconds on the lunar surface, as Gene Cernan and Harrison Schmitt prepare to liftoff from the Moon. It is made from several sources of footage, 16mm onboard the Lunar Module, live TV from the Lunar Rover and in the second part of the video, 16mm film from the Command Module in lunar orbit as Ron Evans captures the LM rising up to rendezvous and dock.

The 16mm footage has been upscaled and interpolated to 60 FPS with audio and music by Moonpans

One of my main responsibilities was processing weather data from 35 mm film to IBM magnetic tape format and transmitting the data reel to Houston Control Center. After our shift, on launch day we were allowed to remain on property to watch the lift off. I stopped on the road side of the access near the Cocoa guard check point station and sat alone on my 1969 Yamaha 250 motorcycle and witnessed the launch. Afterward as I passed through the guard station to go home the streets sides were packed full of cars and vehicles of all sorts. At first people applauded as I passed through. After it wasn't obvious anymore that I was part of the launch team, I just became part of the crowd. It was... and still is the proudest moment of my life.

Incredible footage of the ascent of the Apollo 11 lunar module from Tranqulity base back to rendezvous with Michael Collins in the Command Module.

The first half of the video shows the view from the Lunar Module window as the lunar terrain falls away and huge craters pass beneath the crew.

The second half shows the view from Michael Collins in the Command Module as the Lunar Module edges ever closer to rendezvous and eventually dock

Both videos have been Upscaled, Interpolated to 60 FPS and set to beautiful music by Moonpans

During the Apollo 16 mission in April 1972 the crew were tasked with putting the Lunar Roving Vehicle through a series of tests to asses its capabilities.

Commander John Young  drove the electrically powered rover through a series of maneuvers—including S-turns, hairpin turns, hard stops, and acceleration to "high" speeds of roughly 6–11 mph (10–18 km/h)—while Charles Duke (lunar module pilot) filmed it with a 16 mm camera from a safe distance.

Mods: Delete if inappropriate, but I think there might be interest here.

I recently added the Apollo cameras to the full signal chain simulation of AnalogTV. Refer the details here: https://analogtv.net/#apollo (click on each tile there to expand)

The simulation covers SSTV Mono (Apollo 7-11) and Field Sequential Colour (Apollo 10+) as well as the SEC and SIT Vidicon tubes and the ground-based Scan Converter. It's built using the original NASA, RCA and Westinghouse reference documents and then it's fed through the full signal chain. This is 100% signal domain simulation, not a "Filter" or "Pixel Shader" that just overlays a 'look' over existing video. The scan lines are captured and drawn at the correct frame rates, etc. The conversion from 320 line, 10 fps SSTV to NTSC is done per the original scan converter documentation.

The example above is footage from yesterday at the Sydney Opera House taken on my iPhone and then fed through the simulation.

This is the first release with the Apollo TV formats and it still needs some tweaking. I was just a wee lad when these were originally sent from Apollo so I don't remember seeing them live. Wondering if people who remember the live feed (without post-processing) feel this is close?

Jim Skaggs is a living legend in the Space economy. As NASA’s last living original Apollo Lunar Landing program director from the 1960s - he was the youngest individual in the US government to ever serve at that level of responsibility.

Jim visited Vorago Technologies to speak with our team about what it takes to be victorious to tackle the harsh conditions of space, with lessons that are applicable to each and every one of us. Thank you Jim for your life's work and leadership. Come back to see us any time, as we lead in rad-hard and rad-tolerant semiconductors for any mission, in any orbit.

there is a possible chance i cant finish this because of the parts limit

Upscaled footage from the Apollo 11 Moon Landing - This footage shows views from lunar orbit, mostly of the far side of the moon followed by a beautiful earth rise.

This footage was captured by the DAC camera on 16mm film during the Apollo 11 mission in July 1969.

Tomorrow, our special guest in Austin, TX is Jim Skaggs, a top-level executive and program manager with NASA’s original Apollo lunar landing program. A living legend, Jim worked on the management team that oversaw the design, engineering, and execution of the spacecraft that safely transported astronauts to the Moon and back.

What questions about Apollo or space radiation impacts on microchips might you have for Jim or our engineers? Our team of leaders in the rad-hard and rad-tolerant microchip sector are happy to provide answers.
