How We’re Talking to New Horizons

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.

New Horizon’s Flypast

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.

Putting Tatooine to Shame

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.

New Horizons

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.

LeBron James in the NBA Finals

I really do not know much about basketball. I did not realise that the finals had been going on. But, rest assured, they were. The Washington Post looked at whether or not LeBron James had the best finals match performances since 1985. It turns out, not so much. For those of you from the Chicago area, you may instead take solace that one of those guys from that Chicago team represents well.

Donald Trump is Running for President

This week saw a few new people officially jump into the 2016 election: Jeb Bush and Donald Trump. Next week I want to at least look at some design-related elements to the forthcoming primaries. But, today is Friday. So let’s get to the important stuff first: Donald Trump’s hair. Thankfully, Time has that covered. (Get it?)

Rotting Wooden Beams

Earlier this week a balcony collapse in Berkeley, California killed six Irish students. The building had only been finished in 2007 and was barely ten years old. While the investigation is ongoing, the Los Angeles Times reported on what might have been the cause: dry rot.

Aircraft Cabin Flow

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.

Screening Your Luggage

Another weekend, another weekend trip. This time I’m flying to Philadelphia for a quick trip back home. Naturally, I’m going to pack a suitcase so I can bring some things back to Chicago from civilisation. But what happens to my luggage between my checking it and it being loaded onto the aircraft? Thanks to the National Post, we have a graphic to explain just that.
