A Motorcycle Rider Defines Space Situational Awareness

20170415_125541

There’s been a lot of hand-wringing in recent years regarding space situational awareness (SSA). Almost every month another article appears, portending of the upcoming calamity in space–the point in which one rogue satellite or a chunk of debris hits another satellite or chunk of debris. These two chunks initiate a celestial version of pool. As in pool, one chunk will hit another chunk which speeds on to hit another chunk or cluster of chunks. The struck chunks fan out, hitting other chunks, and then those chunks hit even more chunks, and so on.

Invariably the hand-wringing prompts online conversations about whether this space-snooker-based scenario is realistically depicted in the movie “Gravity” (that Sandra, she floats so gracefully in space). Inevitably, a new round of blog posts use the computer-generated picture showing thousands of pixels surrounding the Earth–with each pixel representing one of the tens of thousands of objects, normally junk, orbiting the Earth.

The resulting picture from these conversations and blog posts is clear–the end is nigh, space-wise. Humanity has once again junked up another environment, and will soon reap what’s been sown. Unless we stop those smaller, less expensive satellites from messing it all up. Or something like that anyway.

According to some people, the number of objects (satellites, debris, rocket bodies, etc.) in orbit is reaching scary levels–tens of thousands–which is why they are verbally wringing their hands for public consumption. Is this a “chicken-littling” of space, or is there really something to worry about here? Is the blame for debris really so clear cut? Before getting to the answer, it’s probably useful to define SSA, particularly for readers new to the space arena.

There are many folks with specific definitions of SSA. The U.S. military is interested in the position, identification, and activities of objects orbiting the Earth which might potentially compromise the U.S. ability to defend itself or carry out global missions. The Europeans encompass some of the U.S. military SSA definition, but include discovering and identifying Near Earth Objects–things in space that might eventually literally have an impact on Earth if they get too close–and space weather.

For this post’s purposes, I will use my motorcycle and traffic survival skills to demonstrate SSA, but if you’re a car driver, you’ve been using aspects of SSA already.

When I first bought my motorcycle, I went through a motorcycle safety class (it’s a useful class–take it if you can). The class imparted one particular acronym that stays with me even now, 17 years later: SIPDE. Each word in the acronym suggests a way to survive on the road and hones great habits for motorcycle riding. S–Scan; I-Identify; P-Predict; D-Decide; E-Execute.

SIPDE reminds a rider to constantly use the tools at hand– eyes, brain, and motor skills-to make a rider aware of what’s happening close by, and then do something to keep the rider safe. Eyes scan for anything that may literally impact the rider. Once a rider’s eyes see something, the rider’s mind identifies it, internally racking and stacking the “threat.”

A rider then predicts what the object may do (a dog or child might run obliviously into the road, a self-righteous cyclist might blow through the stop sign from the left, a truck driver in the rear view mirror is on the phone and might not even see the rider). Once the prediction is made, the rider decides on a course of action, and then does it. This kind of cycle goes on if it’s ingrained in the rider, and it all will take place in seconds.

So, how do motorcycles and SIPDE have anything to do with space?  Essentially the same actions help define SSA, except a satellite takes the place of the rider. The orbit is the “road” the satellite is on. The tools for scanning, instead of a rider’s eyes and brain, are networks radars and telescopes on Earth’s surface–although some nations have a few space-based SSA “eyes” too. The brains are the people and computers trying to make sense of what’s nearby in orbit (is an object at the same altitude, is it on a path to intersect with another satellite’s “road,” etc.).

These people and computers are also attempting to identify objects close to the satellite’s “road”–its orbit (is it the body of a rocket, is it small debris, is it a satellite that seems to be moving from it’s orbit). Once they figure out what an object is, then they must decide whether the object is a threat, and predict possible actions of the object. The people in this SSA network must then decide what to do and then do it. This may be as simple as notifying satellite owners about a possible collision, or just monitoring the same objects to see if anything changes.

But how bad is it really, out there? Exactly how many objects are orbiting the Earth? Again, is this a “chicken-littling” of space, or is there really something to worry about? Is the blame for debris really so clear cut?

The answer, as it always seems to be, is: it depends. That’s where I’ll end it today, but my next post should hopefully give some perspective.

Space, Spring, Snow, Schmoozing, and finally, Snoozing

Setting up New Shepard for launch…Symposium launch, that is.

Wow, what a week!

And yes, the picture above shows Blue Origin’s New Shepard suborbital space launch vehicle being set up.  It’s the same one that launched and then safely landed, five times, near Van Horn, Texas. Really–the real one. The last New Shepard test launch was the most spectacular and you can watch that here, should you wish to. The launch happened around the 51-minute mark in the video below. Blue Origin is entitled to some chest-thumping, I think.

Blue Origin was cool enough to put the vehicle on display in front of the Broadmoor Hotel for nearly a week during Space Symposium this year. A mock-up capsule sat next to it. I’m pretty sure it’s on its way to Seattle to be put on display in a museum there–but that’s just a guess. Wherever it goes, I’m glad I got to see it up close this last week. Here’s my night shot of the rocket. And, yes, the scorch marks are real.

This is a pretty sweet moment for someone who comes from space operations. And this is just the beginning–a beginning that’s been put on hold for decades.

For those of you who don’t know, I work for the Space Foundation, and we just finished hosting the 33rd Annual Space Symposium here in Colorado Springs. It’s a big event for us, and we try to get nearly everyone who has their finger in the space industry pie involved. There aren’t much more than 50 employees in the Space Foundation, so the event is an “all-hands-on-deck” exercise. Education, philanthropic, government, marketing, customer service, museum and research departments all work together towards one goal. Heck, most of the last month was me getting my hands around our Technical Track program.

The Blue Origin capsule. Oddly, there was always a line for this display ;-).

And the Symposium’s success certainly would not be possible if we didn’t have over 300 of the most awesome volunteers in the world helping us. You can meet some of them at our museum, the Discovery Center, here in Colorado Springs.

The Symposium is a big networking event for the global space industry. And people pay a lot of money to network and show off their businesses, which is a little weird to me still. But every person I talked with there seems to like it, so there you go. It’s also pretty neat that so many people from other countries were there: China, Russia, Ukraine, Japan, Germany, Belgium, the Netherlands, and more. So many countries involved in the industry of space, and it’s growing. We can see it growing just because we’re running out of space for the company and agency exhibitors at the Symposium.

Snow and rockets in Spring, in Colorado Springs. Typical for us. Maybe it’s this way in Baikonur, too?

Even some Australians were there, obviously a little jealous of New Zealand’s score of hosting Rocket Lab’s launch pad. Some of them confided in me that New Zealand’s space involvement is probably the best thing to have happened to Australia. I guess the spaceport got someone’s attention, although Australia has had plenty of opportunity to get involved in space for some time.

This is what it looks like behind the stage when a speaker gets a little too verbose…the red light means the speaker has gone over time–in this case one minute and forty-one seconds. It eventually was over 9 minutes…

I tried hard, as the Foundation’s analyst, to talk with anyone I could. It’s what I like doing, especially to help with analysis of the industry. But, and this is not a complaint and just the reality, Symposium duties remain above all during this time. I’ll have to chat with those folks at other events.

So, we had Space Symposium. So what? What’s next? A lot of it depends on the very people who attended the event. Do they intend to follow through on their plans for space? Is everyone’s plan even feasible? If it’s a healthy, open space market, then the answer to that will be “No.” It’s sure going to be interesting, though.

The end of Symposium is always a mixture of sadness and relief for me. I really do love helping with the event–it’s akin to running a mission or a test (but without the heavy consequences if something goes wrong). And I’ve always come alive for those, as I do for Symposium. But at the same time, and I know most of the folks I work with feel the same way, it’s nice to be able to put feet up on the sofa at home, and veg out on Netflix once the event is over. It just takes a lot of energy, at least for me, to not just conduct the event, but talk with people.

One more thing. I discovered it’s pretty great to work with my wife. She was sort of shanghaied to help us at the last minute. But she seemed to like it, and instead of missing her while working 12-18 hour days, I could actually admire the work she was doing. She may have been surprised at all the work we do during this event, but she seemed fine working with us.

I hope I’ll be able to write a bit more now that Symposium is over. Please stay tuned…

Friday–the day after Symposium. Blue Origin’s New Shepard is ready to ship out. And so are we.

Two Years Later as a Space Industry Analyst

https://i1.wp.com/www.brookepatmor.com/wp-content/uploads/2013/01/transitions.jpg

Happy New Year!

Transitions are not unfamiliar to me. During my childhood, our family moved around a lot. We’d move to other countries occasionally, always from assignment to assignment on different Air Force bases. Each move contained challenges and over time, each time, I looked forward to the moves. A move meant I would see something different, make new friends, and learn something new. It was great being a Air Force “brat.”

I’d like to think growing up in a military family, moving, and as a result, adapting and learning, have influenced me positively. I might never have learned German, German culture, or eventually become aware of different perspectives from the American Way. My tolerance for risk might have been lower or non-existent. I might never have tried to make my luck with writing.

I have the same attitude towards job transitions. Each new job means there’s something new to learn, something different. So, how do I feel about changing from a satellite missile defense test manager and space operator to my current position as a space industry research analyst? It’s been over two years since I took on this writing gig.

I like the change! Heck yeah, I really like this last transition! I’m learning a lot, too.

I’ve always had an affinity for writing. My degree was in communications, for goodness sakes. I definitely am better at expressing myself in writing than speaking. Writing allows for my brain’s background processing to come to the fore in a nice tidy package once the processing is done. Writing about the space industry is icing on the cake.

But it’s not just about writing about the industry. It’s also learning about the industry, conducting research, finding great sources, reading whatever I can find, which can sometimes seem unrelated. Then I think about it all. I think about it in the gym. I think about it when I’m watching TV at home. I think about it when I’m sleeping. It’s the way my brain likes to work. Some of my better insights come from listening to podcasts not at all connected to my research. Some of my ideas just fall in my lap while running on the treadmill. It’s not tiring, and it’s not forced.

So, yes, my current job is a blast. So much so, I don’t really feel like it’s a job. I get to meet with interesting people from around the world. I get to study and learn about new trends in the industry. I get to write it all down. And, shockingly, people find the information I bring to them useful. It doesn’t hurt I’ve got a good boss, who also has a good boss. It doesn’t hurt I’m on a team full of great people. But what motivates me is finding and writing an analysis people use. It’s wonderful when that happens.

It’s not all sunshine and tea cakes all the time. And the transition between jobs was a bit rough, as part of the problem was me trying to figure out what I REALLY wanted to do. But I can honestly say I feel more fulfilled in this job than my prior work. Admittedly, my experiences and lessons learned in my prior work helped me in my transition to this job. And I’m still learning a lot. So I’ll mention a quick overview of my perception of the space industry today.

There is so much going on in the space industry, a person researching the category would really have to work hard to NOT learn something. Space situational awareness, small satellite growth, possible new entries in the launch market, reusable rocket stages, and more—there’s always a learning moment waiting around the corner. And that’s assuming a person stuck with studying only the American launch industry. But globally, there are trends that impact the launch industry, too.

There are the activities conducted by India and China. Both countries have very active space programs, with China’s commitment evidenced in it’s recent 2016 attainment as the world’s most prolific launcher for that year (actually, they tied with the US this year–I just finished updating our database–sorry). The Europeans haven’t been sitting still either. And there’s surely a story behind Russia’s alarming decline in launches for 2016 as well as a seeming decline in launch reliability, too.

That’s not to say that the U.S. is lagging. From my observation, the U.S. space industry is perhaps the most innovative and most vibrant it’s been in a while. But the U.S. space industry is also in transition, slowly switching from primarily government-sponsored missions relying on government launch services, to a healthier, and hopefully multi-pronged launch industry with many more customers. There are many, many plans, from many entrepreneurs and companies, some of which may actually transition to real businesses and opportunities.

The upshot is, I get to research, learn, ponder, and write about this changing and interesting industry. It’s been fun during the past few years, and I’m pretty sure it will be fun for the next few. This was a fortunate transition for me. Sorry if that sounds like bragging.

Transitions can be wonderful—if you have the means, I highly recommend picking one up. Oh, yeah!

 

Two Past Visions of the Future

20161106_112804.jpg

Two things this week made me think about the how people in the past looked at the future, particularly regarding space exploration. The first was a movie, and the second was an article on Brickset.com’s site about certain space LEGO kits from the past.

The movie, Forbidden Planet, is one of my favorite movies. It was my favorite movie when I first watched it at the age of 12, and has been since. My appreciation of this movie is so high and obvious, my wife gifted me with the DVD anniversary edition of the movie many years ago. We watched it again last night.

It had been a long time since I last watched the show, and I must admit before watching it last night, I was afraid I wouldn’t like it as much as I had before. Thankfully, my appreciation of the story and special effects in the movie have not diminished, but grown. There are some issues, such as the men’s treatment of the female character, Altaira, but on the whole, it’s story still holds up.

I won’t get into the story itself, which is fun and thought-provoking. I just don’t think my description actually will ever be able to do Forbidden Planet’s storyline any kind of justice. I will say the story involves a ship’s captain (any “Airplane!” and “Naked Gun” aficionados might appreciate him), a mysterious professor, an awesome robot, an alien planet, a beautiful woman, and a deadly monster. You could read summaries about the movie on various sites, but most won’t give readers an accurate “feel” of the story either.

I do urge you to watch it–the movie’s special effects, art, costumes, and models come together as an interesting snapshot of the future of space and technology in the 1950’s.

While the special effects are “quaint” by the standards of today’s blockbusters, they were probably top of the line back in the 1950’s (I don’t know for sure, I wasn’t there). The panoramas of the planet, the blaster fire, and the ship, are, instead of mind-blowing, now quite “pretty” per my wife. There is an art involved in the effects, because there were artists involved with the effects back then–apparently drawing them on the celluloid world frame by frame.

But what I like most of all, aside from the story, are the structures. The professor’s home and office are an homage to “mid-century modern” in the architecture, the furnishings, and the decorations. That was what the future would be like, according to certain folks in the 1950’s, and you can seem some glimpses of this future in certain neighborhoods in built during the late 1950’s and early 1960’s in the United States.

The captain’s ship and appearances of technology are all part of a recipe to make a child excited about exploring the galaxy. The saucer-shape of the starship, stasis beams used during hyperdrive activity, blasters, and glass globes and equipment whose purpose aren’t quite defined, but just look “futurey” are part of the inspiration. Then there are passenger cars able to go hundreds of miles an hour and the ability for building whatever is required, using molecular technology. The future was exciting story of possibility to kids, and a few adults.

 

I think Walt Disney and his architects agreed with this and maybe took some elements in the movie as their inspiration for their parks. For anyone who has ever wandered Disneyland’s and Disney World’s old “Tomorrowland”(before significant teardowns and restructuring), and EPCOT Center, there were elements used in the parks that are quite similar to the structures and technology used in Forbidden Planet. I don’t think it was a case of ripping off the movie, but more of a consensus of what the future in 1950’s America was going to be.

Because I am a fan of the design and architecture of “mid-century modern,” it’s a future I certainly wouldn’t hesitate moving towards.

The other vision involves all the fun ways LEGO tried to bring their vision of space, particularly NASA’s space vehicles, to children. Brickset.com does a great job in this post going through the different kits LEGO brought out. Again, as a child, I would have been ecstatic to build my own Saturn rocket on a launch pad, not matter how janky it looked. The imagination filled in whatever shortcomings reality had.

The beauty about the LEGO kits are that kids could deviate and build slightly different versions of space vehicles and probes. It didn’t matter, so long as the child remained inspired and excited enough to continue their exploration of our history and possible future for going out in the Universe.

Whether from LEGO or from MGM, each different vision served different markets and came from different companies. But b0th contain very optimistic messages about man’s place in the galaxy. Sure, these are toys and science fiction movies we’re talking about. However, they both encompass visions that fascinate and maybe motivate a few of us. It’s definitely fun just to go back, even if only for a few hours, and explore the universe according to the 1950’s.

If you have access to Amazon, Forbidden Planet is there for you, if you’re interested. I search Netflix with no success. Or go to one of your local DVD dumping grounds–they will likely have a copy available.

 

Another “Space Watch” article…

s66-54455

“Ride ’em cowboy”–a bit of encouragement Pete Conrad gives to Richard Gordon while straddling the spacecraft. Image from NASA.

While I’ve been lying low content-wise on the site here, I’ve been staying pretty busy at work. One of the many fun things I get to do is to look up historic events leading up to the Apollo moon missions, and then write a little bit about the event for the Space Foundation’s “Space Watch” monthly newsletter.

In this particular “Space Watch” article, titled Gordon’s Orbital Garbage Disposal and Rocket Herding Service,” I try to describe the activities of two brave astronauts during a Gemini mission fifty years ago. What they did gives the category of “space operations” an entirely different meaning, and shows just what kind of interesting and courageous explorers they were.

While many NASA fans seem to attribute the administration’s achievements to the idea of NASA itself, I’ve always felt it was the people within, such as Gordon and Conrad in this story, who really moved the agency forward toward the lunar missions and subsequent successes. This is not to downplay the mission controllers, engineers, and others who all played their part. Indeed, it’s the team, the people, who figure out how to overcome challenges, and then move ahead. But the astronauts in particular put their lives on the line during space missions. Whether it’s NASA, or in the future, one particular company or other that starts regular manned flights to space, the professionals called astronauts will still be the ones trading the ability to “fly” in space with the possibility of real, deathly, consequences.

With these thoughts in mind, I hope you enjoy Gordon’s Orbital Garbage Disposal and Rocket Herding Service.”
