Here’s some beautiful descent footage from the Chang’e-4 spacecraft that made the first ever soft landing on the far side of the moon last week. When it rotated quickly toward the surface at 1:01, I found myself instinctively saying with a grin, “Pitchover!” I’d suggest viewing this full-screen.
Here’s the descent profile you’re seeing in that video:
The Lunar Reconnaissance Orbiter team have determined where Chang’e-4 touched down, its approximate position in the Von Kármán crater shown in the older LRO imagery of the area below. LRO will next pass over the Chang’e-4 site toward the end of this month, when they ought to be able to snap a picture of the lander on the surface. Depending on LRO’s altitude at the time, it will show up as anything from a few bright pixels – remember that it’s just the far side and not a dark side – to something showing a bit more detail of the lander, the rover, and perhaps its tracks.
First full panorama released of the landing site, produced from 80 images:
Low earth orbit is not the most exciting place to be in space, but I’ll admit it is extraordinary at times. This is the launch of a Progress cargo ship taken from the ISS eight days ago, captured in a fashion Stanley Kubrick would have appreciated. Best viewed full-screen and in the dark. The Soyuz launch vehicle first appears about 6 seconds in.

- DescriptionTimelapse of the Russian Progress MS-10 cargo spacecraft launched on 16 November 2018 at 18:14 GMT from Baikonur cosmodrome, Kazakhstan, taken by ESA astronaut Alexander Gerst from the International Space Station.The spacecraft was launched atop a Soyuz rocket with 2564 kg of cargo and supplies. Flying at 28 800 km/h, 400 km high, the International Space Station requires regular supplies from Earth such as this Progress launch. Spacecraft are launched after the Space Station flies overhead so they catch up with the orbital outpost to dock, in this case two days later on 18 November 2018.The images were taken from the European-built Cupola module with a camera set to take pictures at regular intervals. The pictures are then played quickly after each other at 8 to 16 times normal speed. The video shows around 15 minutes of the launch at normal speed.The Progress spacecraft delivered food, fuel and supplies, including about 750 kg of propellant, 75 kg of oxygen and air and 440 l of water.Some notable moments in this video are:
00:07 Soyuz-FG rocket booster separation.
00:19 Core stage separation.
00:34:05 Core stage starts burning in the atmosphere as it returns to Earth after having spent all its fuel.
00:34:19 Progress spacecraft separates from rocket and enters orbit to catch up with the International Space Station.
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.
I also got these three enlarged to 16×20″ and they’re up elsewhere in the house:
Surprise, surprise, there will be no slaughtering of tourists around the moon in Q4 2018 as originally stated early last year. That’s a sensible thing. Besides, nobody but the worst of humanity would want to see the millions of laugh-cry emojis that would inevitably be pasted willy-nilly by the worst of humanity.
“If I’ve told you media people once, I’ve told you a hundred million times that I never engage in hyperbole! Ever, do you hear me? Now get out or I call in the bulldozers!”

After writing of my fireball meteor experience as a kid below, I did a little digging and found out I was wrong about two things: First, I was actually a few months shy of my seventh birthday when it happened, which, thanks to the fairly amazing web, I discovered was 7:14pm Eastern Time on Sunday, 25 April 1966. Second, the fireball lasted almost 30 seconds, not 8. I knew it was visible for a long time, and my friend and I saw it from the start, but I was being conservative with my recall. Because I remember us shouting – likely pretty tame stuff like “Holy crap!” – and, I think, leaping up and down for quite a while, my recollection was 20 seconds or more, but I doubted that as I wrote the post because even 10 seconds is a long time for any meteor to be visible. I shall trust my memory more in future.
It was called the “Great Fireball of 1966” and was widely seen on the East Coast of the US and in Canada. It was a bolide – meaning it broke up as it sped in – estimated to be 5-10 feet across, and since it wasn’t part of any expected meteor shower, it might have been a small asteroid. It was written up in Life magazine and Sky & Telescope at the time – pictures from those issues below.
When we saw it, it seemed to be only several miles above us, maybe forty or fifty thousand feet, but the show actually began near the Kármán line, commonly accepted as the point space begins, 62 miles/100 km up. Its initial altitude of 327,000 feet explains why it seemed to move fairly slowly.
A research paper dissecting the meteor was published in the Journal of the Royal Astronomical Society of Canada and is available here.
I said in yesterday’s post that I could show where we were and the path of the meteor, and so I can with Google Street View. My house was just to the left of frame here, and we were next door, sitting on the steps at street level at the green X. I’ve darkened the sky in this image to approximate the light at the time, and the color of the line in the sky is just about the color of the meteor we saw, except it was matchhead-bright, of course. I can’t recall precisely if it went below the horizon, but I believe we did see it breaking up toward the end.

This was a heady time for me. I was already heavily into the space programme, with Gemini in full swing and Apollo about to start. The next milestone for me was this oblique view of the Copernicus crater on the Ocean of Storms, sent back by Lunar Orbiter 2 seven months later, in November 1966:
This photograph, iconic at the time, came to be known as “the picture of the century” and it’s hard for me to disagree. It was taken from an altitude of 27 miles/45 km and 200 km/125 miles away from the centre of the crater. No one had seen such a spectacular view of the moon before. The funny thing is, the photo was entirely unintentional. They simply needed to advance the film in the onboard camera, so they fired a couple of “housekeeping” exposures – random ones as far as they were concerned, but just look at what they got.
That photo was mind-bending for me and made more concrete the prospect of people being there, which would happen in just a couple more years. Before that happened, 2001: A Space Odyssey was released in April 1968 and I saw it at its Boston premiere on a huge, curved Cinerama screen perhaps seventy feet wide. Eight months after that, Apollo 8 carried the first men to leave the Earth and orbit the moon. And then it just got better and better from there. It was one helluva time to be alive.

From Sacramento FD, 15 December 2017: Sacramento Engine 316 as part of California OES Strike Team 4805c, preparing to depart Ventura Base Camp for a day on the fire line. The Thomas Fire is now 252,500 acres, with 35% containment and 8,369 personnel assigned.
Hundreds of units are visible in their photo from the Ventura County Fairgrounds. Other totals as of 15 December: 1,012 fire engines, 62 water tenders, 32 helicopters, 158 handcrews, 78 bulldozers, plus other firefighting aircraft.
In the MODIS natural colour image below, smoke from California wildfires stretches north past the Oregon border. The southern half of Vancouver Island is visible at the top and the lower edge of this image is about 175 miles south of the Baja California border. Acquired by NASA’s Aqua satellite on 11 December 2017.
Aqua’s Atmospheric Infrared Sounder (AIRS) shows CO concentration on 11 December 2017. “Column” refers to the 5km-high column of air that’s measured and 1018 is one quintillion.

When I was a kid and through my late teens, I regularly visited the Government Printing Office Bookstore in Boston. The Federal Building was just a short walk from North Station, so I’d take the train in – never once getting kidnapped or murdered that I recall. They had a whole corner devoted to NASA books, usually forty or fifty of the most recent volumes, so for me, it was like visiting the Kennedy Space Center in miniature. I didn’t have much money, but I’m pretty sure train fare for the twenty-five minute run into town was between US$2 and $3 each way, so ten bucks carefully saved up would cover the trip plus one or two books.
I got several of my NASA books right there, at their gloriously low original GPO prices. For example, the 681-page This New Ocean: A History of Project Mercury was US$5.50. This collectSPACE article lists most of the better NASA history volumes that were at one time or another in the bookstore.
The P in GPO now stands for Publishing, not Printing, and the Boston GPO Bookstore closed in 2001, but I still have all the books I got there. Now the real reason for this article is not nostalgia or sidelong swipes at milk-carton-kid-based helicopter parenting, satisfying though those are, but this: I recently found something of a bonanza for people who are interested in these books in their original form but don’t want to spend US$50, $100, or more for them – or who, like me, own them but would love the convenience and frugality of free PDFs of the originals. The NASA Technical Reports Server has full page-by-page scans – and good quality scans, I’ll point out – of many of the original books, including:
- This New Ocean: A History of Project Mercury (select the larger PDF)
- On the Shoulders of Titans: A History of Project Gemini
- Moonport: A History of Apollo Launch Facilities and Operations
- Chariots for Apollo: A History of Manned Lunar Spacecraft
- Stages to Saturn: A Technological History of the Apollo/Saturn Launch Vehicles
There are other good volumes there as well, including Apollo Expeditions to the Moon – mine was $2.25, but it’s now $40 or $50 for a good condition original – Where No Man Has Gone Before, and the like. The part 1-3 articles linked in the collectSPACE article above mention more of these – there’s also a final part 5 not linked there. The best way to search the NTRS site is with NASA SP-nnnn where nnnn is the publication number.

I missed this good news a couple weeks ago: After three months of study, NASA has rejected the utterly idiotic idea of attempting to put astronauts around the moon on the very first test flight of the Space Launch System. The New York Times story on their decision is here.
Now who’s going to put their foot down and say “No” to Mr. Musk’s plan to off a couple of billionaire tourists?
When I was eight, I saw 2001: A Space Odyssey during its Boston premiere on a huge, bowed Cinerama screen. It was April 1968, eight months before Frank Borman, Jim Lovell, and Bill Anders flew Apollo 8 around the moon at Christmas and fourteen months before we landed. What dreams I had! I took this photo just now of the 2001 insert style poster – the paintings by Robert McCall – that’s on the wall just behind me. Sometimes I look at it and sigh a little.
