But also, sorry. This piece was supposed to go up Wednesday after President Trump’s speech where he announced he’d like to spend $1 trillion on infrastructure. But it didn’t post, so you will get two today.
This article from the New York Times dates from about a week or so ago at the height of the flooding out in California. During that deluge, the Oroville Dam emergency spillway partially failed. And a week prior to that, the Twentyone Mile Dam in Nevada burst.
Dams require investment and maintenance along with roads, railways, airports, and well practically all infrastructure. The article leads in with a map locating all those dam locations across the United States and colour codes them by age.
The article outlines the potential costs and risks associated with all this dam stuff and is worth a quick read. It also includes some nice secondary graphics about the dam hazard potential in Nevada.
Sorry, not sorry.

Last Friday China seized a US Navy submersible drone—like the drones the Air Force uses but for underwater purposes—in international waters off the coast of the Philippines. This graphic from the Washington Post shows how, while in international waters, the seizure occurred not far outside China’s Nine-dash Line, which they claim as territorial waters.

AT&T is attempting to merge with Time Warner in order to have more/better control of a content pipeline. But as this Wall Street Journal article points out, the concept of tie-ups between media and telecoms is not exactly new. Especially since the breakup of the old Bell Telephone company.

When I was in high school I began to listen to music. To find music. To find artists. A guy who owned and operated the store next to where I worked recommended David Bowie, that guy whose songs I had heard on Philly’s classic rock radio stations. Back in those days we still had record stores—not that I knew what a record was—and I found a few used CDs—now that kids today would know what a CD is. Over that summer, I picked up a lot of new music. But what struck me about this David Bowie guy is that Space Oddity, Tonight, and Heathen all sounded so different from each other. He was a great one. And while I’m certain there will be some graphic in the future about his timeline—how can there not—today I am going to follow up once more on the North Korean nuclear test after coming across this graphic from Reuters.
You will recall how last week I looked at a New York Times post that explained the differences between a few different types of nuclear weapons. Well, here Reuters illustrates those differences.
By now you should all know that I am a sucker for small multiples. They are a great way of separating out noise and letting each object be seen for its own. You should also know that I am a sucker for things industrial, e.g. nuclear power. So when you put the two together like NPR did earlier this month, well, I am going to be a huge fan.
So New Horizons is long since gone from Pluto. But it will still take 16 months to send back all the photographs and science. Why so long? Because so far away. 3 billion miles away. Put another way, light from the sun takes eight minutes to reach Earth as it travels at, well, the speed of light. Radio signals that travel at the speed of light take 4.5 hours to reach Earth from Pluto. So imagine trying to send large data files that far away at a download speed less than that of a 56k modem, for those of you old enough to remember such a thing.
But what receives these radio signals? NASA’s Deep Space Network of antennae that allow NASA to communicate with spacecraft and such things that are in, wait for it, deep space. These antennae are scattered throughout the world, but in this screenshot taken Monday, you can see just what the antennae at the various complexes are doing. Here, we see New Horizons (NHPC) just prior to its flypast communicating with the large antenna at the Madrid complex. The lack of signal lines indicates that it is preparing to setup, takedown, or is tracking the spacecraft.
As a fun aside, I left the tab open in the browser and a few hours later came back to find the Deep Space Network sending signals to the Mars rover Opportunity (MER1), the Chandra X-Ray Observatory (CHDR), and the Mars Reconnaissance Orbiter (MRO) amongst others.

A little after 07.30 EDT, New Horizons began its race past Pluto, what your author grew up learning as the ninth planet in the Solar System—the last planet to be explored. I recall thinking that when it launched back in 2006 I had no idea what I would be doing nine years later. Or at least I think I thought that. It launched nine years ago, almost a third of my life. Regardless, I was definitely one of those upset with the decision to downgrade Pluto from planet to dwarf planet. Anyway, a decade on, there New Horizons is. By the time this post goes live, she will be barreling away towards the Kuiper Belt while transmitting her photographs and science data.
This piece from the New York Times looks at what happened earlier today in, for Americans, the wee hours of the morning.
So this is generally a more serious post than usual for a Friday. Because, it is about New Horizons, the probe we launched almost a decade ago to explore Pluto, which at that point was still technically a planet. Anyway, the Washington Post has a nice illustration detailing the various sensors and orbits and trajectories. But what gets it a Friday post? Its sense of scale.
If you remember a little while back, Amtrak No. 188 derailed in North Philadelphia at Frankford Junction. I covered it here and here. Well, the New York Times has analysed the Northeast Corridor to identify the curviest segments of track, excluding entrances and exits from stations. Perhaps as no surprise, Frankford Junction is right among the top segments.

Today’s post looks at an illustration from the BBC about aircraft cabin flow. As I have flown on four aircraft in the last month—quite a lot for me—I do recall thinking during one particular flight just where the air intakes were on the aircraft. It never dawned on me that they were in the actual engines themselves.
I think from a design side the only thing I would change is the width of the line for the airflow. That would show how while some is released, replacement air comes from the air mixing unit.
