CDLXVIII – Eclipse

Today is Solar Eclipse day, if you weren’t aware. I am not in line of totality, but I’ll be going to see what I can see.

I’ve talked about this before, perhaps, but I’m feeling romantic about the occasion. I like to joke that Space was my first love. I’ve been in love with the stars since I was a wee lad, and I was given a kids book with cardboard pages that showed planets and comets and all manner of space things. I can’t explain why. Someone (JMSmith perhaps?) suggested that a better description is “the heavens” and I always liked that, but I haven’t yet managed to make that language my own.

There’s something beautiful about the movements of the heavens and the heavenly bodies. The Grand Design of creation. Some people compete about the kind of existentialism space makes them feel. “Man I really feel insignificant looking at the stars.”

I always protest that I do not feel insignificant looking at the stars. It’s not that I feel significant–but in a strange, small way, God designed the heavens to be beautiful for us. He knew that we would look to the stars in wonder, and He wanted us to have something worth looking at. And God being God, he made it detailed, intricate, beautiful–a tapestry of infinite worth, a pearl of infinite price, an unattainable goal, an infinite well to study. In the movie “Moneyball” there’s a scene where an unlikely hero hits a home run, and Billy Beane leans back in his chair while watching the tape and says, “How can you not be romantic about baseball?”

I say–“How can you not be romantic about the heavens?”

Today is a Solar Eclipse, an alignment of the earth, sun, and moon. A brief moment where the heavenly bodies align just so and remind us just how big space is, how much bigger God is, and that this beautiful show could not have been coordinated by anything less than our all-mighty Father.

Perhaps I love space and have always loved space because there’s a little piece of me that always knew it was divine. Because somewhere in time and space and beyond time and space, in the eternal now, the Divine looked on creation, and some part of Him thought, “Scoot is gonna love this.” Not because Scoot is worth anything, but because that’s the infinite depth of God’s love for his dusty, meager, broken, fallen creation.

If you get a chance to see it, at the local peak of the eclipse–remember that this is a love poem from God to you written in the heavens. And say a little prayer, in love, back to Him–back to the Author of creation, who set the heavens in motion.

God love you.

(c) – The Prodigal Son’s Brother Owns A Telescope

I love space. I have been an astronomy nut since I was a wee lad. I distinctly remember my love of space being rooted in an interest in dinosaurs. I remember learning that the dinosaurs were killed by a giant space rock and for some reason that fascinated me. I received in 2nd grade two books with cardboard pages with various facts about both dinosaurs and space and I credit the space book with being the launching point for my lifelong love affair with the stars.

To that end, this love is mostly a private love. I do not identify myself except in topic-specific blog posts as an astronomy nerd. I am interested by manned and robotic space missions, but those do not define my love of space. I am interested by astro-physics but those do not define my love of space. My love of space is closer to a love of beauty, a love of creation, and not a love of knowledge or a love of humanity. Did you know there are different kinds of spiral galaxy? The holotype for spiral galaxies is called the “Grand Design Spiral” and I think that is the perfect description and absolute poetry. My favorite thing in space that you’ve never heard of is Hoag’s Object, because of the mystery and beauty of it, not because name dropping Hoag’s Object gives me a sense of superiority.

You may be aware that the James Webb Space Telescope was recently launched, activated, and started publishing it’s first images. This is great news. But I have a weird mix of emotions. I feel like the author of the song, “My Angel Is A Centerfold”, because my private love of space is being turned into a fad consumer product. I feel like the brother of the prodigal son because I am envious that my loyal love of space is being shared.

There is a phenomenon of intellectual leftists treating space as the ultimate credential. “I am not just a physicist, I am an astro-physicist, so that makes me better than you”–putting astro in front of any field of study automatically makes the bearer a high-priest of scientism. Astro-botanist, astro-geologist. Astro-accountant. This frustrates me because it takes all the beauty out of space. It’s like doing a forensic analysis of brush strokes and paint chemistry on a van Gogh painting–you aren’t appreciating the beauty of it, when you get to that micro of a level.

This is all a public demonstration of my moral failings as a human. I am not superior for loving space in my particular way. I don’t really understand why pop-culture space bothers me so much. It shouldn’t, but here I am. I guess I am writing this partly to vent that feeling, partly to check if anyone else has felt the same thing.

CCV – A Ramble About Space

I’ve referred occasionally to the fact that I am a space enthusiast. I’m listening to an instrumental song and watching a montage of Cassini images this morning while simultaneously trying to figure out where and how to direct the desire to write. So why not write a little something on the subject of space.


Popular Science is presently obsessed with Mars and Jupiter. Not without reason, they are fascinating planets but also some of the most extensively observed. I’m almost looking forward to humans going to Mars just so we can stop sending Rovers and pretending they are discovering anything new. Part of the reason Mars and Jupiter are so popular is because they are fairly easy to get to from Earth. Anything beyond Jupiter requires more time (and rocket fuel) to get to; anything closer to the Sun than Earth requires elaborate and extensive maneuvers in order to shed the momentum given to it by the Earth. Mars and Jupiter happen to be in the sweet spot of study.

Again–not without good reason. Jupiter, for all it’s observation, is still fairly enigmatic. Personally, my favorite thing about Jupiter is it’s moons. My fascination there began with 2001: A Space Odyssey and has evolved since then. Ganymede with it’s varied terrain, Io with it’s volcanism. Europa I believe will be getting it’s own mission launched in 2022. Jupiter currently has a probe named Juno orbiting it, but due to a technical issue is stuck in a long 53 day elliptical polar orbit. I believe it was supposed to move into a tighter orbit around Jupiter but wasn’t able to. I don’t know how this has impacted the intended scientific study but the images have certainly been spectacular–prior to Juno no one had seen the Jovian poles.

For Mars, I think it’s been fairly established that there is currently water on Mars and it used to be a warmer, wetter planet. Mars’ molten iron core solidified and so it’s dynamic magnetic field disappeared, which allowed it’s atmosphere to gradually deplete and it turned into the deserted world we know and love today. We also can be reasonably certain there are microbes of some kind on Mars. Popular Science will call this “life” but that’s only to make people think of aliens–it’s the equivalent of going to Greenland and finding moss on a rock. It does not strike me as unusual that microbes would be on Mars–in fact, I would be rather surprised if they weren’t, personally. I would enjoy some detailed study of Mars’ moons but they are so small that it would be almost impossible to orbit them, let alone land on them. It would be more of a rendezvous sequence than a landing. Russia tried sending a probe named Phobos Grunt (Phobos Ground) but due to technical issues it failed to return any observations and may have crashed into Mars.

Saturn has captured the popular imagination mostly thanks to it’s rings and the Cassini mission, but because the Cassini mission was so successful I think it has sapped the will to send another Cassini style probe any time soon. Until technology improves, the only study we will get of Saturn will likely be in passing.

My favorite recent mission was the fly by of Pluto. I watched that fairly eagerly because prior to arrival the only images we had were extremely low resolution. Pluto is a fascinating and dynamic world, the visit by New Horizons raised more questions than answers. Far from being a homogeneous snowball, it had mountains and valleys and the heart-shaped region is an enormous sea of frozen nitrogen. I would be curious to see a follow up mission.

Probably the two planets I am most interested in learning more about are Venus and Neptune. Venus is a good, close candidate for research but steals money away from Mars Mania so has not gotten a favorable look. The challenges involved with getting there and then peering through the dense and toxic atmosphere increase the cost hurdle. Neptune is deserving of a Cassini style orbiter but is much farther away than Saturn. We haven’t been since Voyager 2 and there is suspicion that Neptune’s moon Triton is a captured Kuiper Belt object because of it’s superficial resemblance to Pluto and it’s retrograde orbit.

The trade-off with any mission to space is speed, and weight. A fast rocket can’t stay in orbit and can’t be heavy, so can’t make a lot of observations. A slow rocket can stay in orbit but takes a long time just to get anywhere–when it does we can have a Cassini style orbiter which spends more than a decade in orbit and get lots of observations. This makes it much costlier as a consequence. This trade-off could be eased somewhat if we could cheaply launch rockets from the moon, but that just shifts the costs earlier in the production cycle. We have to get out of the Earth’s gravity well somehow, and unless we source and process materials directly from outside of earth, the gravity well will remain a dollar well, too.

This has been a ramble about space.

CXI – Faster Than Light (1)

I was sitting in a bar when they arrived. I could tell without looking because there were three or four of them that shuffled awkwardly through the single door, and the conversation in the crowd stopped as they made their way towards me.

Two sat on either side of me, and–yes, it was just one–one stood behind.

“You guys sure come out in force. Want a drink? Want a drink? It’s on me.” I ask the group. No response. Humorless Suits!

“I’m Jim Porter, with NASA.” Said the guy on my right.
I held out a hand. “How do you do, Jim. I’m Graeme Turner.”
“I know.”
“It’s just courtesy man, shake my hand.”
He shook my hand. “We wanted to come in person and share the news. The results are back from the evaluations.”
“Oh yeah? I presume you wouldn’t come all this way to tell me I didn’t make it.”
Jim smiled, it looked like for the first time in his life. “Right. You’re in.”
“Great! Who else?”
“No one. Just you.”
“What? There were like two dozen other test pilots you had running around. You’re not taking any of them?”
“We just need one.”
“What if I get sick? Get nervous? Say no?”
“Who said we came to you first?”
I stared into my beer for a moment. “Touche. I’m humbled. Sounds like we need to celebrate. Seriously are none of you guys having a beer?”
“No. We’d like you to come with us, so we can begin preparing immediately.”
“Why the rush?”
“Can’t tell you until you come with us.”
“What did you pick me for?”
“We can’t tell you until you come with us.”
“Where are we going?”
“Graeme. We can not tell you until you come with us.” He said, emphasizing each word.
“Do I have a choice?”
“No.”

I downed the rest of my beer. “Well ok then. Let’s go!”


Jim started talking fast as soon as the door to the car closed, something about schedules and plans and equipment.

“Jim, you gotta slow down.” I said. “None of this makes a lick of sense to me unless you tell me what it is I’ve just agreed to do.”

“Well, the long and short of it is, we’ve got Faster than Light Travel, and you’re going to be the first human to fly it.”

I felt like I’d just been sucker punched. My head spun. I couldn’t find words.

“No, we’re not joking. We reverse engineered it from the derelict we found out near Jupiter. We think the Japanese beat us to it but if we can get a human test before them…”

“Have you tested it on…not humans?”

“Mostly sensor suites. We’ve sent probes here and there. But none of it tells us if it’s suitable for humans.”

“So I’m a guinea pig.”

“You’re a test pilot for the government, you’ve always been a guinea pig. This is not new to you, Graeme. If you die, you’ll have the fastest, most spectacular death of any human ever. If you live, you’ll be a hero; the first human to travel faster than light.”

“That’s reassuring Jim, thanks.”

“We’ll get you a technical brief when we arrive.”


The next few hours were a blur. We arrived at some secret facility. I signed some forms. I was sent here. Sent there. Pick up this. Sign for that. None of this made any sense to me. They assigned me a place to sleep, and I slept. Maybe it was the beer, but I slept better than I had in years. Even when they woke me up 6 hours later, I felt refreshed.

It was Jim again. “I’ve gotta take you to the nerds.”

“Suits, nerds, it’s all the same to me. When do you have to take me?”

“Now.”

“Not going to give me a minute to wake up?”

“It’s been two minutes since I walked in here.”

“You’re just full of jokes aren’t you, Jim. Everyone’s a comedian around here. Alright take me to the nerds.”

We wound our way through the labyrinthine halls of the compound to a conference room where bespectacled engineers stood fussing around a long table and what appeared to be a model plane.

“Ah, Graeme Turner?” Said the lead nerd, striding towards me with an outstretched hand, “Barry Singh, it is a pleasure to meet you. These are the engineering team leads behind your craft. That’s Helen Coates with Structural design; Tommy Chen with Quantum Mechanics; Louis Mosby with sensors and interface; and finally James Morris who led the engineering team behind the drive itself.”

I took a seat as the team was introduced. “Sounds great. Always nice to put faces and names to the people responsible for keeping me alive.” They laughed politely. I pointed to the model plane, “So what the hell is this?”

Barry looked to James, “You want to start us off?”

“Sure.” James sat down heavily and pulled the model closer to him. “This is the X-206C, your FTL spacecraft.”

“Catchy name,” I quipped.

“They have a naming convention established for when they Christen the ship but i’m telling you the official designation because they haven’t done that yet. So for now, X-206C will do. You might be thinking what I thought when I first saw it, that it was kind of ugly. Nothing like the classic science fiction. You’re right, this is an ugly ship, because it’s not so much a ship as a piece of equipment you’re going to be clinging to. We tried to keep it as stout as possible, for reasons Tommy can explain better than I. You can think of this thing in terms of modules. This little pod here is the tin can you get to sit in. This long section here is rocket fuel for conventional thrusters, the main exhaust connects here and here, with the maneuvering thrusters along the x, y, and z axes here. The FTL drive itself is surprisingly compact, we placed it centrally along the body here, and these three prongs sticking out are essential components. These are your quantum deployment masts which fold out from the ship, which we decided in case we want to launch these from the surface–the same consideration for making the main exhaust compatible with our current booster regimes. Your job, simply put, will be to fly, turn around, and come back. Are you following me so far?”

“I’m following you so far.”

“Ok. Here’s where it gets tricky. Every pilot needs to know the capabilities of his craft. I’m going to need you to listen carefully because this is how you will actually be achieving FTL status.”

I put down my pen–I was doodling in the margins anyway–and looked attentively at James.

“The principle is this. You’re familiar with space-time? Of course you are. Space has the dimensions x, y, and z, and also time. We move around in space at will, and are pushed inexorably forward through time. Time is the control dimension we cannot change. This drive capitalizes on technology which inverts that dimension. Space functions like time. Think of it this way. We can sit here and do nothing and we’ll move 30 seconds forward in time. In this dimension, we can sit there and do nothing and move 30 miles forward in space. Because of this inversion, you can cross unfathomable distances without progressing through time.”

“What? How do we navigate? If we can just do nothing and travel through space, why do we need all these thrusters?”

“That’s a good question. Honestly we don’t know whether you will experience time or not. 206B was equipped with a chronometer and it was still in sync when we brought it back, less distortions from the nominal thrusting. We don’t really know how you will experience this. We know these things: That it’s point to point navigation, that gravity has a repulsive effect on your trajectory, and the only way we have to pull you out of the dimension right now is by using that repulsive force to bring you to a stop.”

“What does that even mean? You’re pointing me towards an obstacle and I’ll stop before I hit it?”

“Essentially. We lost 206A because it went past Jupiter and the gravity well pushed it off course. Consequently we aren’t able to bring it back to assess some of the sensory equipment, though we know where it is. It’s location helped us refine the trajectory for 206B. The Roche Sphere is the gravitational well around planets and stars that, if you are within, you will be captured by the planet and pulled in. Using this drive means that it’s the point where the FTL thrust and the gravitational repulsion reach equilibrium. The quantum disruption brings you out of the dimensional inversion and you return to normal space. The trick is that you will be going the speed you were going when you entered the inversion.”

“So i’m going to be accelerating into a gravity well.”

“Yes. But once you enter normal space you’ll be able to maneuver, and the Roche Sphere gives you plenty of room to navigate. Far from being captured and sucked in, you’ll be able to maneuver as normal. Our planned trajectory has you approaching Jupiter, maneuvering so your trajectory rounds Jupiter, and once you’re clear if the Roche sphere you can FTL back to Earth. You might say that the whole thing will be over before it’s even begun.”

Some of the nerds snickered.

“Alright,” I said, “So how do I fly this thing?”
