Cinnamon tree just out of range

Chang’e 4 (left arrow) and its rover captured by the Lunar Reconnaissance Orbiter Camera on 8 February

The source LROC article is here. As to the title: The Chang’e lander is named after the goddess of the moon and the rover, Yutu 2, takes its name from the large jade rabbit said to accompany her. Both were mentioned as Apollo 11 orbited the moon prior to landing. From the mission transcript:

095:17:28 Capcom Ron Evans: Roger. Among the large headlines concerning Apollo this morning is one asking that you watch for a lovely girl with a big rabbit. An ancient legend says a beautiful Chinese girl called Chang-O has been living there for 4,000 years. It seems she was banished to the Moon because she stole the pill of immortality from her husband. You might also look for her companion, a large Chinese rabbit, who is easy to spot since he is always standing on his hind feet in the shade of a cinnamon tree. The name of the rabbit is not reported.

[Chang-O is also spelled Ch’ang O and, in the more modern rendition, Chang’e. Chang’e was subsequently adopted as the name of the Chinese unmanned lunar exploration programme, the first spacecraft of which was launched in 2007. The third in the series, Chang’e 3, was the first to land which it did autonomously on 14 December 2013 in Mare Imbrium. The rabbit’s name of Yutu, stated by Evans as not reported, was given as the name of the first Chinese lunar rover, delivered to the surface by Chang’e 3 and it translates to ‘Jade Rabbit’.]

095:18:15 CMP Michael Collins: Okay. We’ll keep a close eye out for the bunny girl.

Apollo 11 documentary update

The trailer for “Apollo 11” is out, and the reviews for its premiere last week at Sundance are quite enthusiastic, so there’s a chance of it having more than the very limited theatrical release Sundance-selected documentaries usually get. Here’s hoping.

“It’s one thing to boast about the specs of these images, and quite another to see the spruced up footage for yourself. It’s rare that picture quality can inspire a physical reaction, but the opening moments of ‘Apollo 11,’ in which a NASA camera crew roams around the base of the rocket and spies on some of the people who’ve come to gawk at it from a beach across the water, are vivid enough to melt away the screen that stands between them. The clarity takes your breath away, and it does so in the blink of an eye; your body will react to it before your brain has time to process why, after a lifetime of casual interest, you’re suddenly overcome by the sheer enormity of what it meant to leave the Earth and land somewhere else.”
– David Ehrlich, Indiewire

I was glad to see that, at least in the trailer, they used none of the footage previously seen in the 1972 “Moonwalk One” documentary.

“There was one guy, his name was Urs Furrer, and he was a well-known cameraman. He was a big guy – his name means ‘bear’ and he was big like a bear. I’d look for him because I knew that he could put this camera on his shoulder. I don’t know how much it weighed with a thousand feet of film on it; it was a ton. But he could use it like a handheld camera.”
– Theo Kamecke, director of “Moonwalk One”

Found Apollo footage

A new documentary called Apollo 11 that features never publicly seen footage is in its final stages. That footage is part of a miles-long cache that’s been squirreled away in the National Archives ever since a planned MGM Studios project on the story of Apollo was cancelled in 1969. After the cancellation, some of the footage was used in the 1972 Moonwalk One documentary – included below – and the unseen footage being used now is the leftovers from both of those projects. Vanity Fair has the details on the discovery here.

A few weeks ago, the new film was selected as one of the documentaries that will be premiered at the Sundance Festival early next year. If I wasn’t in the final few months of my five-years-to-debt-free project, I think I’d give serious consideration to visiting Utah for the first time. I’d have to find something else to do as well, of course – I rarely make even a local trip without at least two purposes in mind.

From the Vanity Fair article:

In May of last year, [director Todd] Miller received a startling e-mail from [National Archive and Records Administration archive supervisor Dan] Rooney. “I was used to the way in which archivists and librarians communicate, which is typically very monotone, very even keel,” Miller said. “But I get this e-mail from Dan, and it’s just insanely long and full of exclamation points and bolded words.” Rooney’s staff had located a cache of old reels that he identified as the “65mm Panavision collection.” (In this format, the negative is shot on 65-mm. film and then printed as a 70-mm. positive.) “The collection consists of approximately 165 source reels of materials, covering Apollo 8 through Apollo 13,” Rooney wrote. “Thus far, we have definitively identified 61 of those 165 that relate directly to the Apollo 11 mission, including astronaut mission preparations, launch, recovery, and astronaut engagement and tours after the mission.”

Moonwalk One full version, from 1972. If you’ve got Amazon Prime, a much better recently-restored copy is free there.

I’m a wee bit more interested in this film than First Man.

“I take back any bad things I ever said about MIT — which I never have.”

The quotation is from Mike Collins, Command Module Pilot of Apollo 11, as their spacecraft entered lunar orbit. He was commenting on how well the computer had controlled their Lunar Orbit Insertion burn, adjusting their course to velocities accurate within a tenth of a foot per second in all three axes – essentially perfect. In full, from the onboard audio recording:

Minus 1, minus 1, plus 1. Jesus! I take back any bad things I ever said about MIT – which I never have.

Collins wrote the best of the astronaut biographies, Carrying the Fire, and he turned 88 today. He’s behind the moon in this crew photo, when all three of them, born in 1930, were 39:

MIT’s Department of Aeronautics and Astronautics curriculum includes a graduate semester devoted to “Engineering Apollo” – where twenty-six class sessions barely scratch the surface, according to the professor in the first video below – itself one of those twenty-six classes. Collins was a guest there in 2015 and last year.

Apollo 17 documentary

I happened upon an excellent 104-minute documentary from 2015 I’d never heard of before, titled “The Apollo Experience: Apollo 17” and linked below. It’s among the best single-mission Apollo documentaries I’ve seen and I figured I should mention it here because it has to be pretty darned obscure for me to not know of it.

I have the complete lunar surface videos from the mission – the boxed set pictured at the end of this post – but this documentary puts EVA highlights in context with explanatory captions and follows the mission from training to splashdown. The archival footage throughout is of the highest quality I’ve seen and quite a treat on a fifty-inch television.

The overall quality is high enough that I forgive the engine noise the producers added to some radio transmissions, along with other low-key add-ons like electronic “beep-beep” effects. They did them in a fashion subtle enough that, while I knew immediately that they were their additions, I wasn’t compelled to say “Wut?” and put on my just-ate-a-lemon face.

Timeline’s YouTube channel is worth exploring as it has hundreds of other history documentaries. Some, like this one, come from obscure satellite channels, but it appears a large percentage of their content originally aired on Channel 4 in the UK.

“So Over the Moon” – a rebuttal by Frank Borman himself

From the fact that it featured prominently in last week’s The News Quiz on BBC Radio 4, I gather that the Frank Borman segment a few weeks ago on “This American Life” titled “So Over the Moon” has gained a fair amount of traction. The conclusion of the TAL segment was that the Apollo 8 mission he commanded bored him, wasn’t enjoyable or interesting at all, and was in the end just a battle in the Cold War to him.

Based on past talks he’s given, one in particular, I begged to differ and sent this to the “This American Life” folks:

Regarding the “So Over the Moon” segment of episode 655, please relay to David Kestenbaum the link below of Frank Borman giving a talk at the National Air & Space Museum on the occasion of the 30th anniversary of Apollo 8 in 1998. I think Borman actually did have at least a little fun going to the moon and it held his interest a skosh more than he let on recently. Yes, he emphasizes in his 1998 talk the race against the Soviets as the most important part – as he’s always done – but he also tells great stories and cracks jokes left and right about the Apollo 8 mission during his 73-minute talk. He’s a funny guy – the opposite in some ways of the man I heard on TAL a few weeks ago.

My 2015 article linked below includes a 6-minute clip I placed on YouTube of a portion of Borman’s talk plus a link to the full-length 73-minute video on C-SPAN’s site.

We all get grumpy from time to time; perhaps it just wasn’t the best time to speak with him.

What he shared of his wife Susan’s condition on TAL would beat anybody right down to the ground. They married in 1950. I can’t even imagine what he’s going through.

Hallway update

I added a new 12×36″ enlargement to my refreshed hallway gallery today, a 1:3 aspect ratio crop of a high-resolution scan of the photo of the first flight of the Wright Flyer on 17 December 1903 at Kill Devil Hills, North Carolina.

Orville is piloting and that’s Wilbur at the wingtip. John Daniels, one of the five witnesses to the flight, took the photograph with Orville’s pre-positioned camera – so awed by what he saw that he almost forgot to squeeze the bulb to capture this image on the 5×7″ glass plate negative.

From the Flyer to the Apollo 16 Lunar Module Orion above it was a span of just sixty-eight years and four months.

The full-size first flight image from the Library of Congress can be found here – be aware that it’s 27MB.

Edited to add: The comments here include a discussion in some detail of the soon-to-be-released film “First Man” and HBO’s 12-part 1998 series “From the Earth to the Moon”.

Don’t get me started

The excerpt below is from the site of Apollo 17 Lunar Module Pilot and geologist Harrison “Jack” Schmitt, and it’s the most…well, invigorating description of a jump start I’ve ever read.

This goes hand-in-hand with my article on the explosive guillotine in the Lunar Module because Schmitt describes an emergency scenario that Apollo crews planned for and practiced in which the launch sequence has failed: The guillotine has not fired, the four explosive bolts holding the two stages together have not exploded, and the ascent engine has not started. This is one of several contingency methods mission planners worked out.

Bear in mind as you read Schmitt’s explanation that this would be happening after they had tossed their Portable Life Support System backpacks out onto the lunar surface to save weight during the ascent, and after they had closed up the LM and repressurized the cabin in preparation for departure from the lunar surface.

It’s not often I find something about Apollo I’ve never heard before, and this one is boggling. I bolded the last bit of the excerpt because that’s the point when the ramifications sank in and my eyebrows shot off.

Wednesday, November 8th [1972], brought on our last full Lunar Ascent Mission Simulation involving Mission Control in Houston. Six weeks hence, we hoped we would be undertaking the real thing and departing the Moon at the conclusion of a highly successful exploration effort. This “Sim” required over three straight hours in LMS2, including the debriefing with SIMSUP (Simulation Supervisor). Failure or degradation of the primary guidance or engine ignition subsystems constituted the primary concerns addressed in Ascent Simulations. We particularly worked through several scenarios involving failure of the various software-initiated means of igniting the Ascent Engine.

We did not have a great deal of concern about our Challenger Lunar Module, like all the others before it, having just one Ascent Engine, because, in fact, it was at least two engines that just looked like one. Only the solid metal fuel and oxidizer injector ring and the exhaust nozzle below that ring did not have identical, that is, “redundant” components that would function even if a primary component failed. No one could imagine a failure mode for these non-electronic and solid pieces of hardware.

If all internal Ascent Engine ignition options actually failed, and many such options existed to fall back on, we also had a set of jumper cables that could be used as a next to last backup to ignite the Ascent Engine. These were called the “ED/APS Emergency Jumper Cable” and would use power from an independent Pyrotechnic Battery in the Descent Stage to open the engine’s fuel and oxidizer valves and fire the pyrotechnic cable and bolt cutters that would simultaneously separate us from the Descent Stage.

To use the second of these cables, however, one of us would need to egress Challenger in order to access a regular Descent Stage battery. Integrity checks of our suit would determine which one of us would perform this emergency EVA. If Cernan’s pressure suit did not pass its pre-egress checks sufficiently to permit egress with the jumper cables, we would change positions in the cabin, a tough task on its own. As we would have already jettisoned our Portable Life Support Systems, it would be necessary to use the OPS (Oxygen Purge System) we had retained to support the EVA that Evans would perform to retrieve film canisters from America’s Scientific Equipment Bay after leaving lunar orbit for home. The 8000 psi oxygen bottle in the OPS could provide a maximum of 30 minutes of oxygen and air-cooling once activated. There would be no water cooling, however, without a PLSS.

With the Challenger’s cabin depressurized, the winner of the integrity check contest would take one end of the pair of cables out the hatch and down the ladder and move to QUAD III where a battery could be accessed. He would then tear away the Kevlar covers and attach the color-coded pair of cables to the positive and negative terminals of a battery and then return to the cabin. At the optimum liftoff time for ascent into a rendezvous sequence with Evans, Cernan would attach the cables to two circuit breakers near his left shoulder. This action would supply instant power to the two sets of hypergolic (ignite on contact) hydrazine and nitrous oxide valves in the Ascent Engine. Once power reached these valves, they would open and lock open. With opening of these valves, a signal would go to the cable and bolt cutters. We would be instantly on our way into lunar orbit, still in an un-pressurized cabin, dragging our jumper cables behind us. Once back in lunar orbit, we could clear and seal the hatch and pressurize the cabin.

The aim of this emergency EVA was to bypass relay boxes, internal wiring, and the Explosive Devices control panel in order to get power directly from a descent stage battery.

The descent stage explosive device battery, aka the pyro battery, in question was near the front, highlighted here. This procedure bypassed that in favor of a regular descent stage battery.

In later LMs, Apollo 17’s included, five descent stage batteries were at the back of the LM, shown below in an illustration from the Lunar Module LM 10 through LM 14 Vehicle Familiarization Manual [link to PDF]. Two of the five had low voltage taps; the jumper cable would be affixed to one of those.

I’m glad they never had to do this, but it actually sounds like it would work. You might think, “Yeah, except for all the cardiac arrests and such”, but you have to remember that these guys were cool customers. Witness the fact that they practiced for this instead of climbing out of the sim and seeking the nearest bar posthaste when told of the method.

Schmitt says this method was the “next to last backup”, which makes me wonder intensely what on Earth Moon the last backup was. Spit and baling wire?

Edited 24 August 2018 to add: The entire emergency EVA procedure is detailed in Apollo Operations Handbook/Lunar Module/LM 11 and Subsequent/Volume II Operational Procedures, available on the Apollo Lunar Surface Journal site. See section 5.4.25 Loss of ED Sub-system.

https://www.hq.nasa.gov/alsj/LM11HandbookVol2.pdf

I think I found the answer to my “What’s the last backup?” question there: The other choice was to quickly get to the rover – in the case of Apollo 17, parked about 158 meters away for best liftoff camera coverage – start it up, drive it back to the LM, and hook up to one of its two batteries. Now that would really be a jump start for the ages, but I think far less preferable considering there was just 30 minutes of oxygen available in the OPS.

Posters and framing on the cheap

Click for a larger version

Last weekend, I refreshed the pictures in my upstairs hallway, the new ones shown above. As a frame of reference, the photo shows an area of about 7×3 feet. For about a hundred dollars total, I was able to get three 16×20″ prints and one 12×36″ panorama of high-resolution Apollo-era photographs from Shutterfly and mount them in the best borderless clip frames available.

There was a time when I did my own picture mounting on foam board and framing using mail-order Nielsen #11 frame pieces and locally-sourced, custom-cut sheet glass (I never attempted matting), but these days I most often use clip frames – good ones, that is – because they’re easier, they look clean and classy, and they’re a lot cheaper than professional framing or even DIY Nielsens. The last picture I had mounted, double-matted, and framed, the “Clipper at the Gate” shown below, cost me well north of US$200 – and that didn’t include the signed print, which I had purchased several years previously. Don’t get me wrong – the framing and matting is well-done and quite attractive, but I have a lot of drawings, paintings, and photos on my walls and I am well south of a millionaire.

I was able to get those four hallway prints done both well and on the cheap thanks to four things:

  • In recent years, the negatives from the Apollo programme have been scanned with better equipment and at much higher resolution, which allows for nice-looking enlargements – not the case with the low-res images previously available. In the case of the three-foot-wide print, someone stitched together a 10,000-pixel-wide image from a panorama photo series Charlie Duke took during Apollo 16.
  • The recently completed Lunar Orbiter Image Recovery Project used current technology to produce, from the data on hundreds of carefully preserved original 1960s magtapes, awe-inspiring photos far beyond the resolution and quality NASA could produce fifty years ago. The top middle picture in the hallway is an oblique photo of Copernicus from 150 miles south of the crater that was taken by chance during a “let’s move the film forward a bit” housekeeping task on Lunar Orbiter 2.
  • A plethora of discounts, including 40% or 50% off sales that Shutterfly runs every week or two, periodic Visa Checkout deals (US$25 off the next order), and even $25 Shutterfly credits that Best Buy includes with many hard drive purchases means you can easily get prints in these bigger sizes for $12-$16 each. That’s cheap for high quality large prints.
  • Massachusetts-based Quadro Frames, which I’ve used for many years, produces the highest quality borderless clip frames I’ve seen; other, more widely-available types are mostly flimsy and ill-fitting. 16×20″ frames from Quadro are US$12.50 and it’s $20 for 12×36″. Each frame is precisely fashioned and includes a sturdy, non-bending backing board with perfectly cut, strong clip channels on the back, pristine and perfectly clear PET plastic glazing panels with peel-off protective sheets on both sides (or glass panels for just $3 more), and more than enough clips that slip into the back channel with a satisfying firm snap. Even their care in shipping to guarantee safe arrival is the best possible: I always think, “Wow, just look at that” when I open boxes from them. For some of my orders, I’ll wager it’s taken them half an hour or more to pack the materials so fastidiously. It’s a good example of corporate responsibility and pride in doing things right.

Here are the source photographs I uploaded to Shutterfly for the hallway prints. You can pause the slideshow and right-click to view and/or save any image at its full size.
