How Type 1 Diabetes is like Mission Control

Last week I showed you some views behind the scenes at NASA, I hope you enjoyed those because it may be awhile until you have more interesting photos to feast on. We are now moving into our “Boot Camp” phase where we learn all of the common content between subsystems on board the International Space Station. It’s a little more intense than tours that take all afternoon!

As I was intently listening to the lectures this week, a few key phrases, thoughts and ideals were repeated over and over and over. Of course, we are learning how these relate to our jobs in mission control, but outside of work I realized a lot of these nuggets of knowledge rang true for those of us whose lives have been affected by Type 1 Diabetes. I’m sure you must think I’m a bit off my rocker for trying to draw comparisons between Mission Control and a life with Type 1 Diabetes, but it’s not as different as it seems.

For instance, the International Space Station is arguably the most complex machine ever built by man, coming in with a cost around $150 billion. But Type 1 Diabetes is one of the most complex diseases to understand, with no concrete reasons for diagnosis and no ultimate “cure” (yet). The disease is estimated to cost approximately $245 billion per year to diagnose, treat and maintain. And both systems require combinations of micro and macro corrections, check-ins, and software updates to maintain successfully.

Situation Awareness

Today I had a three hour lesson on the levels and categories of situational awareness. It was actually helpful to break up this usually vague topic into more specific levels and to understand how critical SA was on each of those levels. The first level is “perception”  - this is where we take in the information we are seeing (monitoring, cue detection, current states, etc.). As a Type 1 Diabetic I practice this form of SA almost constantly. I am constantly checking my CGM, taking a blood reading, reading nutritional facts for the foods I am about to consume, responding to low blood sugar feelings, etc. This type of SA is second nature for most of us, most of the time.

The second level of SA is “Comprehension”. This level raises the bar and requires the person to synthesize disjointed information using pattern recognition, interpretation, evaluation, training, and experience. I think this is a skill that takes practice. If you have only been diagnosed 2 weeks, you will most likely struggle to put together all of the events that lead to a low blood sugar (exercise from 2 hours ago, combined with a large lunch requiring SWAG and overbolusing, not watching trending CGM data, etc). But, after a while, maybe even a few years, this becomes easier (although never perfect, something I will talk about later). However, the mental model must be updated each time a new piece of equipment or capability becomes available.

The third level of SA is definitely the most difficult, it is the “Projection” level. This is the ability to extrapolate the information available now to predict what will happen in the future. For instance, if I had a low carb dinner and see a two hour flat-line trend at 100 before bed, I can combine that with my knowledge of tightly controlled basal rates overnight to predict that I will maintain an even blood sugar throughout the night and wake up with a blood sugar within my specified range. This is a fairly straight forward example, but there are many more complex equations that we use to predict where our blood sugar will be far in advance. Sometimes we are right and sometimes we are wrong, but hopefully that experience increases our situational awareness in a future situation.

Plan / Next Worse Failure

Another key concept of mission control is to plan for the “Next Worse Failure.” If this happens, what might be next? In the Diabetes world as in the mission control world this concept often has to do with redundancy. If I lose this power channel, what will be the consequence of losing the next power channel? And in Diabetes words, If my pump transitions into an unrecoverable failure, what is my alternate means of delivering insulin? Or what is my low blood sugar contingency plan? Or how will I check my blood sugar if I’m out of test strips? Etc? As a general rule, I always carry backup insulin via insulin pen, try to keep extra test strips in my purse and my car, and I always have a low blood sugar plan (glucose tabs or other goodies).

Conflict Management

What do we do when our equipment doesn’t agree? Or when we don’t agree with our endo’s recommendations? Or when your pump reported delivering 5.0 units, but your blood sugar is rising up to the 300s? We troubleshoot conflict in the Diabetes world every day. We constantly correct the world’s perceptions about Type 1 and Type 2 and others. Along with the physical conflict manifestations, we also deal with the intellectual and emotional conflicts nested within the Diabetes diagnosis. It’s a constant battle for the mission control team, and for the team controlling this disease.

“To always be aware that suddenly and unexpectedly we may find ourselves in a role where our performance has ultimate consequences.”

That line is a quote from the “Foundations of Mission Operations”. As flight controllers in training our job requires the skills described in the document, and if we are good, they will always be on our minds.  

As Diabetics we could draw up our own mantra, describing the skills required to live day-to-day with this disease. And, as much as we don’t like to think about it or dwell on it, the mission control quote applies to us too. Diabetes can place us (or those who take care of us) suddenly and unexpectedly in a role where our (or their) performance has ultimate consequences. I think this is ultimately what keeps us ticking each day. This notion provides the motivation to shove needles under our skin or draw blood or prick fingers 6 or 7 times a day (or more).

As mission controllers we know space is an unforgiving place, and as Diabetics we know Diabetes doesn’t take any days off.

Did you copy that?


  1. Copy that! I never thought of how similar those two are, that's a great juxtaposition!

MCM - Certified Mom

This morning I woke up early, the baby monitor was chirping just a few minutes before my alarm was set to go off. Chris graciously rolled out of bed and set out to re-insert Otto's paci. Meanwhile, I pressed my clothes, curled my hair and brewed some coffee - my standard pre-console routine. After a quick breakfast Zara peeped her head over the railing and I heard a gentle "mama" echo down the stairs. It was still dark, but this little one was ready for her daily breakfast of oatmeal and milk in preparation for a fun day at swim lessons and school. As she sat, eating her "oatsss" (as she calls them), I whirled around the kitchen prepping bottles, gathering outfits for school, and ensuring all the swim lesson supplies were set out. It's hard leaving Chris to take care of both kids in the morning (#momguilt) so I try my best to complete as many get-ahead tasks as possible, in hopes his morning goes smoothly. 
This morning schedule description may seem mundan…

MCM - On Call

It's definitely Monday. Otto spit up on my work clothes this morning, I forgot to brush my teeth and I sat down in my car forgetting to clean the layer of sand from the beach yesterday. Whoops. But, it's also MONDAY!!!!! Which means you get a special look behind the proverbial curtain of Mission Control in a series I'm dubbing "Mission Control Monday". We all need a little "boost" (pun intended) at the beginning of the week, so why not get it from the heart of Manned Spaceflight itself - NASA's Mission Control
This week I am highlighting the little known fact that sometimes, as an ADCO Specialist, I am scheduled to be "On Call". It just so happens I am "on-call" this week! Even though we don't have a sweet 1990's pager, the ADCO on-call is a Specialist with the cumbersome responsibility of having their cell phone strapped to them at all times. Yes, even during the night. Yes, even when you have a 3 month old. Yes, just…

Experience the Kennedy Space Center

Manned spaceflight is not a challenge forged from one molten idea - it's not a put-this-in get-that-out equation - it's not a sport for the isolationists. The notion that it was "one man's passion" or "one nation's resources" that got us to this engineering moment is simply false. And the idea that alienation could ever lead to exploration is impossible. There is likely no other industry or singular goal so intentional about teamwork - from employing teachers to technicians, soliciting standard to specialized natural resources, planning short term and long, investing in ideas and inspiration, training fresh-outs to experts, and communicating technically and politically. Tangibly, the manned spaceflight challenge crosses borders and age and gender, there are pieces of its presence spanning the entire globe, and beyond! 
One of those spots - notable for it's history as the last piece of Earth many astronauts touched before launch - is the Kennedy…
