Your astronomy lesson for the day: Red Giant Stars
Someday, the star Betelgeuse will run out of fuel, collapse under its own weight, and then rebound in a spectacular supernova explosion. Someday … but probably not soon.
One of my favorite subjects–time!
New research from Griffith University’s Centre for Quantum Dynamics is broadening perspectives on time and space. Associate Professor Joan Vaccaro challenges the long-held presumption that time evolution — the incessant unfolding of the universe over time — is an elemental part of Nature. She suggests there may be a deeper origin due to a difference between the two directions of time: to the future and to the past.
On January 28, 1986, the U.S.A. experienced a tragedy that has since faded into history. If you weren’t yet born at that time, you may not have even heard of it. I remember talking about the space shuttle to a classroom full of junior high students in the late 90s where I was blindsided by a young man who asked whether one had ever blown up. That something indelibly imprinted on my memory could be unknown to someone, even an adolescent, was incredible. Until I realized the simple fact that the kid hadn’t been born yet.
Wow. To me it felt as if it had occurred the day before.
I was a physics major in college with aspirations to work in the aerospace industry. The day we lost the space shuttle, Challenger, for me was a very bad day. Ironically, that’s exactly what NASA calls such an event, a “bad day.” Well, no shit.
Sorry, I usually avoid naughty words in my blogs, but in that context my expansive vocabulary entirely fails me. Somehow nothing defines NASA’s understatement of tragedy as well as an expletive. And much of why I feel that way is because, subsequent to the Challenger accident, I went to work at NASA as a contractor, ultimately winding up in their Safety Division, which meant I was privy to all sorts of dirty little secrets.
When I arrived at Johnson Space Center in Houston in April 1988, the agency was deep into what they referred to as “return to flight”; RTF in NASAspeak, given their propensity for acronyms. RTF comprised the time while they finished investigating the cause and put together design fixes to avoid a similar occurrence in the future, eventually getting back to what NASA did, i.e., send men and women into space. It’s interesting to consider that we didn’t even refer to it as Challenger; it was 51-L, the ill-fated flight’s official designation, which was less emotionally charged than calling it by name.
When I went to work in the Safety Division at Johnson Space Center in 1990, “The Report of the Presidential Commission on the Space Shuttle Challenger Accident” was required reading. This well-written document covered the technical details in a way that even my teen-aged son at the time could understand. I remember him reading it in the backseat of the car during a road trip. That same copy still resides on a shelf in my home office, bristling with numerous sticky notes and highlights marking the parts that struck me the most. But those are but tips of the proverbial iceberg.
As anyone who’s actually familiar with the accident knows, its official cause related to the o-rings in the solid rocket booster which didn’t seal, allowing hot gasses to strike and penetrate the external fuel tank, which resulted in a deadly explosion. A major contributor to o-ring failure was the fact the launch took place when the temperature at Cape Canaveral in Florida was a mere 28 degrees F. This had never before been attempted, Floridian temperatures usually far above that range, even in January. This factor was illustrated dramatically by physicist Richard P. Feynman, a member of the investigation committee, by dropping an o-ring in a glass of ice water to demonstrate how they became brittle and incapable of performing their function at low temperatures.
I lived in Northern Utah at the time of the accident, the manufacturer of the solid rocket boosters (a.k.a. SRBs), Morton Thiokol, located a few dozen miles away. Anyone who lives in such a climate is more than aware of the effects of cold weather. As I recall, the SRBs had never been tested in that temperature range, either.
On the surface, it appears that this tragic accident that claimed the lives of seven astronauts, including teacher Christa McAuliffe, took everyone by surprise. But in reality, as I learned working in Safety for nearly 20 years, it was processes and politics every bit as much as faulty design. They knew; they just ignored it. The true cause was as elusive as missing shuttle pieces still on the bottom of the Atlantic Ocean. [NOTE:–If you’re interested in more sordid details about the Dark Side of NASA, I recommend “Challenger: A Major Malfunction” by Malcolm McConnell or “Prescription for Disaster” by Joseph Trento.]
Anything that can cause a problem, either critical or catastrophic, is documented on a Hazard Report, with o-ring leakage no exception. Hazard Reports (HRs) contain causes along with controls, though some hazards are simply classified as an “accepted risk” if there’s nothing that can be done to prevent them. Space flight is risky and there are some things you simply can’t avoid or control; bird strikes and meteorites come to mind.
O-ring failure was a catastrophic hazard and documented as such. That the design was faulty was likewise known. Engineers had seen leakage on previous flights. Let that sink in for a moment. O-ring failure had happened before. However, earlier instances had not caused an accident. This resulted in a very dangerous and ultimately fatal thought pattern that led them to believe that perhaps it wasn’t as serious as they thought. Previous failures had been investigated, the leakage referred to as “blow-by” and eventually accepted as not a safety issue.
How wrong they were. In reality, they were playing Russian Roulette. Just because they got away with it a few times did not mean it wasn’t a hazard, only that they’d dodged a bullet. A Thiokol engineer named Roger Boisjoly had written a memo before the accident pointing out the seriousness of the problem. It was essentially ignored, most likely for budget and scheduling reasons. Unfortunately, his sordid prophecy of impending disaster was fulfilled almost exactly six months later. Later, to cover their sins, Morton Thiokol and NASA decimated Mr. Boisjoly, typical behavior employed to discredit whistleblowers.
I’d like to point out that for many accidents the public sees Safety as the culprit. Wasn’t it safety’s job to prevent such a horrific occurrence? Yes, it certainly was. And I must say that we did everything possible to assure safety of flight. We were the ones who made sure all risks and hazards were properly controlled and documented. This more refined process, however, was instituted after and because of the Challenger accident. The full rigor of the safety process recommended post 51L by the Presidential Commission was never fully instituted, however. A plethora of subsequent reorgs were supposed to make safety more of a priority, yet somehow eroded, as proven by the Columbia disaster 17 years later. An accident which has a strikingly similar administrative postmortem.
If you remember the movie, “Deep Impact,” you might recall the line where the female member of the crew on that fictitious shuttle flight, charged with protecting our planet from a collision with an approaching asteroid, noted that if they died in service to their country that all they’d probably get was a high school named after them, which is more truth than poetry. So let’s take a moment to remember those seven brave individuals by name who died so needlessly 30 years ago. They represented different genders, races and ethnicities, some professional astronauts, others not.
Francis R. (Dick) Scobee (Commander)
Michael John Smith (Pilot)
Ronald Erwin McNair (Mission Specialist)
Ellison S. Onizuka (Mission Specialist)
Judith Arlene Resnik (Mission Specialist)
Christa McAuliffe (Payload Specialist & school teacher, winner of the “Teacher in Space” competition)
Gregory Bruce Jarvis (Payload Specialist & aerospace engineer, bumped to this flight by a U.S. Senator who took Greg’s original spot)
As they say, those who fail to learn from history are doomed to repeat it. And repeat it they did, within four days of being exactly 17 years later on February 1, 2003 when we lost Columbia.
Watch for more on that tragedy on the 13th anniversary of that disaster.
Excellent article that explains the difference between astronomical and astrological placement of the Sun.
Sun-entry dates to Zodiac constellations in 2016, using boundaries for constellations set by International Astronomical Union in 1930s.
I’m delighted to participate in this blog tour for L.R.W. Lee’s latest episode in the Andy Smithson fantasy series for Middle Grade readers! I had the pleasure of sharing a booth with her at the Austin Book Festival last October and thoroughly enjoyed getting to know this intelligent and fascinating person. Learn more about the fifth book in the series, get to know more about the author and then be sure to grab a copy from the buy links at the end.
Four years ago, Andy Smithson discovered he is the Chosen one to break a 500-yr-old curse plaguing the land of Oomaldee when he unexpectedly and mysteriously found himself there. To do so, he must collect ingredients for a magical potion. Thus far he has gathered the scale of a red dragon, venom from a giant serpent, a unicorn’s horn, and the tail feather of a phoenix. Now he must ask a griffin for one of its talons. There’s just one problem…humans have poached griffin treasure, causing these mythical creatures to attack on sight.
Complicating matters, the evil Abaddon, sovereign of Oomaldee’s northern neighbor, is turning more and more citizens into zolt in his ongoing campaign of terror as he sets in motion the final steps of his plan to conquer the land. Things really start to heat up in book five!
If you loved Harry Potter, you’ll love the Andy Smithson series chalk full of mythical creatures, newly invented animals like zolt, herewolves, and therewolves, a complex plot with evolving characters, and positive themes including responsibility, diligence, dignity, friendship and more.

5 Stars! – “A marvelous book in a great series!” – Erik Weibel (Age 14) This Kid Reviews Books Blog
“Readers of this series have come to anticipate a host of challenges, intense battles, and on an epic scale. In Vision of the Griffin’s Heart, you won’t be disappointed. For lovers of fantasy, I consider it a must read.” – Richard Weatherly, Author
“One of the admirable qualities I like about the entire series is seeing Andy’s growth from a self-absorbed kid to a more thoughtful teen as he learns how to deal with the various crises which face him, all the while knowing that the future may hold unpleasant consequences. The watchword for Vision of the Griffin’s Heart is “courage.” – Wayne Walker, Home School Book Review
THE DEPTH OF THE ANDY SMITHSON SERIES
If you’re an adult looking for a clean series you can sink your teeth into, Andy Smithson is definitely it! In it I develop four layers simultaneously: 1) Andy Smithson in Lakehills, TX 2) Andy in Oomaldee 3) the Afterlife 4) a meaning layer. A few examples to demonstrate the depth…
Symbolism is used extensively (a couple examples):
Names are also important in this series (a few examples):
Alchemy used throughout the series (a few examples):
The titles of the books manifest yet another layer of meaning and reveal Imogenia’s evolution.
In Vision of the Griffin’s Heart, Imogenia realizes she is gripped by hatred and distrust she has harbored for so long. Unlike griffins who choose to trust others, Imogenia cannot yet make that leap when it comes to her brother.
ABOUT THE AUTHOR
R. W. Lee credits her love of fantasy with her introduction to C. S. Lewis’ Chronicles of Narnia. Later on, she enjoyed the complex world of Middle Earth brought to life by J. R. R. Tolkien in Lord of the Rings and The Hobbit. The multiple dimensions of the worlds mixed with a layer of meaning, captivated her and made her desire to invent Young Adult Fantasy and Epic Fantasy worlds others could get lost in, but also take meaning away from. More recently, L. R. W. Lee has found inspiration from J. K. Rowling and her Harry Potter series as well as Brandon Mull and his best selling Fablehaven, Beyonders and Five Kingdoms series.
R. W. Lee writes to teach her readers principles that can transform their lives – overcoming frustration, impatience, fear and more. She also shows why responsibility, diligence and dignity are the keys to true success in life. She lives in scenic Austin, TX with her husband. Their daughter is a Computer Engineer for Microsoft and their son serves in the Air Force.
L.R.W. LEE INTERVIEW
Andy is patterned after my son. After our first child who was what I would call compliant and seemed to need little to no correction, our son arrived on the scene. As with most 2nd children, he was polar opposite and provided much fodder for an engaging main character.
It has been invaluable for I understand that writing is only 50% of the writer’s success equation. Unlike Field of Dreams, with so many good books available today, just launching it, even on a well trafficked platform like Amazon, does not get recognition. Because of my corporate background, from day one I began working to build a platform – Twitter and Facebook primarily and now also Book Nerd Paradise. As well, I understand the importance of the author community, for no author can succeed these days without the support of fellow authors. My background has also helped in understanding the need to optimize my books to rank well on the variety of sites they are listed on. There’s much more, but those are the biggest helps I would say.
I have to say JK Rowling. The imagination she revealed, the strength of her characters, the world building, the depth of plot over multiple books…she definitely shaped how I think about writing.
Young people are moldable. My passion for writing is to share with readers principles that from my experience can help them live more peaceful lives. A few of these principles include overcoming fear, frustration and impatience as well as understanding that true success in life is not from riches, fame or power, but rather responsibility, diligence and dignity. If they can finish any of my books closer to understanding these principles, I feel very fulfilled.
Designing the story arc is my favorite part of the creative process for you can take a story anywhere your imagination can go. My least favorite part is editing/revising. Even though I know the narrative gets much stronger as a result, it’s still my least favorite part.
Usually about 6 months.
I have to say Mermin, the kindly old wizard who speaks with a lisp. I love him most after Andy because he’s so warm, humble and approachable. He’s fallible and he knows it, which is why he doesn’t apologize for his mistakes, rather he is comfortable in his own skin.
Funny you should ask. Yes, I’m actually noodling with a story arc of a YA Sci Fi story.
I can see how much I’ve changed and improved in showing rather than telling my readers what’s happening. I want them to engage and to show – providing sight, sounds, touch, smell, and taste cues is a big part of that. I was particularly thrilled when my editor came back a full week sooner than expected with this current book because I had improved so much between book three and four. My pocketbook also appreciated that J

One of my first assignments as a NASA contractor at Johnson Space Center in Houston back in the late 80s was to participate in a vendor survey seeking sources of medical equipment used for life science experiments in Spacelab (mock-up used for training purposed pictured above). If an item was available commercially, it could save a tremendous amount of money versus developing one from scratch and essentially reinventing the wheel.
When I would talk to each sales representative, who was usually rather excited to be talking to someone from NASA, the first thing I would ask would be, “Will this particular item work upside down?”
The ensuing silence never failed to make me smile. After a sufficiently dramatic pause, I would explain.
Anything used in space needed to function without any assistance from gravity. This could be something as simple as a reagent moving through a tube or some mechanical part that required a nudge from the 9.8 meters/second/second acceleration of gravity.
Since we’ve all grown up on Earth’s gravity field, it’s easy to take it for granted. In fact, I was amazed to encounter situations where aerospace engineers made the mistake of designing something that was gravity dependent! How ironic is that? That’s how pervasive it is, that even someone trained specifically to work in the space industry would forget that important little detail. Along similar lines, when the shuttle would arrive in orbit, any tools left in the cargo bay, or anywhere else, for that matter, would come floating out, sometimes presenting a serious hazard.
Take a look around and think about some of the things you do every day that depend on gravity. Would your food stay on your plate or your drink in the glass? Nope. Could you wash your clothes in your washing machine? Nope. Would water run out of the tap so you could brush your teeth? Not unless it was under pressure and then it probably wouldn’t go where expected. Floating around looks like a lot of fun, but many an astronaut has battled with space sickness as his or her stomach was quite literally upset with food refusing to settle.
While my heroine, Creena, is onboard the escape pod, she encounters similar issues since it didn’t have a gravity simulator. To quote from “Beyond the Hidden Sky:”
“Nonetheless, there were still a few things she’d never get used to. Like the sanicube. She’d never thought of going to the bathroom or taking a shower as gravity assisted functions before, but they were, with equally bizarre solutions.”
Think about going to the bathroom standing on your head. More than likely, you wouldn’t like the result. Needless to say, toilet facilities in space require innovation to avoid what could otherwise be an extremely unpleasant environment. You can’t pick up a toilet that will work in space at Home Depot, that’s for sure, and developing one was expensive. Even then, it wasn’t ideal. I talked to individuals who were tasked with cleaning up the space shuttle when it returned from a mission who described a rather disgusting mess. Not only would it look as if the astronauts had engaged in numerous food fights, it would smell similar to a port-a-potty as well. Yummy, right?
It was quite common when I would go to schools to talk about space exploration that someone would inevitably ask about the space toilet. It certainly didn’t look anything like a normal commode. It employed assistance from vacuum hoses for urination and a general vacuum for defecation. I had a tour of the toilet training facilities with some of my coworkers one time which, of course, we found somewhat amusing. Potty training for astronauts certainly seemed a bit odd, considering all the high-tech training they received.
The funniest part was that the toilet in the training facility actually had a video camera inside it! This had an important purpose, i.e., so trainees could see if they were correctly parked on the seat, which was required to maintain that vacuum effect noted earlier. Failing to do so would result in, well, the possible escape of something you wouldn’t exactly want to encounter floating around, eh?
It didn’t take long for someone to dub it the “butt cam” and we joked about the possibility of someone broadcasting the training session across NASA Select, the private TV network that spanned not only Johnson Space Center but every other NASA facility and accessible in every conference room, lobby and manager’s office. No doubt the “butt cam” was on a closed circuit, but this shows the type of humor we engineers found in the most unlikely places. Yes, it was definitely fun and interesting to work at NASA.
How many “gravity assisted functions” that we Earthlings take for granted can you think of?
Here’s some interesting and fun information about the Full Moon!
For both the Northern and Southern Hemispheres, the full moons have names corresponding to the calendar months or the seasons of the year.
Instilling a love of math, science and engineering in children is an important step toward preparing them for a good job later in life. My hope as a science fiction author is to contribute to this type of interest and support STEM.
Projections released by the U.S. Department of Education paint a bright future for jobs in the science, technology, engineering and mathematics (STEM) fields. As populations grow, natural resources diminish, disease prevention and treatment become more complex and evolutionary and universal mysteries continue to be explored, STEM will remain critical to expanding human knowledge and solving challenges of today and for the future.
This is actually a little bit creepy since various people have said it was out there for years and that it could have an influence on Earth’s various cycles.
If it exists, the 9th planet has 10 times the mass of Earth – orbits 20 times farther from the sun than Neptune – and takes 20,000 years to orbit the sun once.
