A few weeks back I looked at my ancestral family’s land grant in Wisconsin. Unlike land on the East Coast that was surveyed and organised by pioneers in different colonies using different sets of rules, after the formation of the United States, surveyed land was organised into townships that had subdivisions. In this blog post I found about the subject, there are several diagrams and maps that explain just how this system worked.
How western lands were organised
If you’re curious about how western land was organised, its worth a quick read.

On 6 August 1945, the United States dropped one of the only two nuclear weapons used in combat on the city of Hiroshima, Japan. 70 years later, the city has been rebuilt and the war is long since done and over—the atomic bombings playing no small part in changing the Japanese calculus of surrender. But, what happened on 6 August and then 9 August (when we used the second of two nuclear weapons on Nagasaki)? The Washington Post has this nice piece with illustrations and maps and diagrams to explain it all.

So this is sort of a recycled post, in the sense that I talked about it back in April of 2013. But it’s worth revisiting in light of last month’s announcement of Kepler 452b. For those unaware, the planet is a little bit larger than Earth, but is believed to be a potentially rocky planet like Earth that orbits a star very similar to our Sun in a very similar orbit.

Last night (Central Daylight time), news broke that what might be part of the wing of a Boeing 777, which is the same type of aircraft as the missing Malaysian Flight 370, washed up on the French island of Réunion in the Indian Ocean. The Guardian was following the story last night and one of their reporters used a ocean currents simulator to see if wreckage from a crash off the coast of Perth (western Australia) could make it to Réunion.
So the Red Sox in 2015 are godawful, terrible, bloody bad baseball. But, go back 11 years and they were amazing, fantastic, great and awesome baseball. 2004 was, of course, the year the curse was broken and that was in no small part due to the pitching efforts of Pedro Martinez, who would head down to Flushing in the off-season to end a seven year run of Pedro pitching for Boston. Well, this weekend, after being elected in his first year of eligibility, Pedro enters the Hall of Fame and then will have his number retired at Fenway.
The Boston Globe looked at Pedro, his arsenal, his career, and his best game ever: the 1999 17-strikeout, one-hit performance against the Yankees in Yankee Stadium. The whole piece is worth a looking. But this screenshot shows just how devastating his changeup was, especially in the context of an upper-90s fastball.
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.
From early Monday night
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.
Opportunity is still chugging along on Mars

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.
While the title sounds science-fiction-y, it is true. Star Wars has a famous scenece where a landscape is shown with a binary star system in the sky. But we now know of a quintuple-star system that has two separate sets of binary stars. This BBC article takes a look at how the system is structured.
