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 in case something crazy happens and a second ADCO is needed, or someone gets sick, or someone gets sprayed by a skunk (yes, that really happened).

You may be wondering, what could possibly happen that would require a second ADCO or an ADCO Specialist in the middle of the night? Well friends, there are so.many.things. Space is immensely  unforgiving and any seemingly small problem can turn very serious, very fast. If one of our power channels goes down we could lose multiple computers and gyroscopes that keep the station oriented correctly. If there is a water leak in the cabin, our equipment could be damaged or need to be powered off and leave us without redundancy. If there is a crew medical emergency we may need to undock a Soyuz in an expedited fashion - requiring unplanned changes to attitude control, firing thrusters, or specifically NOT firing thrusters. There could be an unforecasted solar storm that blasts radiation into our sensitive electronics and affects our navigation equipment. There could be a fire that leaves equipment or computers fried, or worse, injures a crew member. But, probably our most imminent threat is a hit from one of the millions of pieces of orbital debris. If the object is big enough to be tracked and heading our way, it is ADCO's job to move the space station out of the way - assuming there is enough time. However, there are millions of pieces that are too small for tracking, but their speed makes them more dangerous than a bullet. And, as you can imagine, a bullet hitting the side of a pressurized spacecraft is a recipe for disaster.

And, while all of these failures affect other systems as well, I have highlighted only the ADCO impacts, illustrating the incredibly complicated nature of this work.


#2 says: To always be aware that suddenly and unexpectedly we may find ourselves in a role where our performance has ultimate consequences. 


So, tonight as I sleep - baby monitor on one side of the bed and cell phone with the ringer on the other, I pray my on-call services won't be needed. But, it IS part of this unique job - I signed up to take on the responsibility to protect a billion dollar spacecraft and the precious lives she holds whether the timing is convenient or not.

The road to curing Type 1 Diabetes

From the moment of diagnosis, the road is rough, the learning curve is steep and the stakes are literally life or death. The map is less-than-helpful - paths originating from virtually every corner, coalescing at a center point (aka "diagnosis") and bursting back outwards - some paths cross and wrap around each other but others are isolated. And even with all of these roads, most of the territory is uncharted - how did we all get here and how will we all exit? Where are the obstacles we haven't found yet? Which passage holds the key to unlocking the solution?

On any given day I feel pretty isolated with this disease - I'm the only T1D in my group at work, the only one in mission control, the only one in my family. I go through the logistics of calling insurance companies, ordering supplies, changing sites and troubleshooting malfunctions mostly on my own. Even those pesky carbs really only get counted in my brain, no group think for a meal bolus here. But there is b…

Hot OJT

Last week I had the chance to mentor a newly certified ADCO trainee - the NASA process is called "Hot On-The-Job-Training", or Hot OJT. What makes it "hot" you ask? Well, essentially I am hands off - he is sitting at the console, working all the plan reviews and updates, making calls to other flight controllers and to the flight director, reacting to anomalies and preparing material for the shift handover. My job is to act as the fault tolerance - a backup ADCO of sorts.

Tuesday was his last official day and by Wednesday morning he was in the backroom sending commands to ISS in preparation for the docking of a three-person Soyuz.


The beauty of this system is the gradual buildup in responsibility. There is a subtle shift from student, to subject matter expert, to fresh operations trainee to advanced trainee and finally to certification and real-time operations flight controller - the process takes two years on average and is considered by many to be enough specializ…

International Travel with Type 1 Diabetes

Whew! Back from one international trip and on to another next week! I will admit my eyes roll every time I get the "we're gunna need to pat you down" talk at TSA, but international travel is a whole different animal. I thought it might be fun to see what goes through my brain and into my bags for these types of trips!


I wouldn't be a NASA Flight Controller if I wasn't good at planning, the key to international travel as a T1D is PLANNING!

3 months prior

Assess supplies. Mine come in 90-days supplies so I like to inventory at least 3 months prior and make a plan to order more early if the trip is going to coincide with the end of my 90-day stock. In my experience supply companies are usually pretty good about adjusting orders as needed if you tell them the reason for the early request - just mention you have an international trip coming up and want to make sure to have plenty of supplies (and backups!) in time. Request a loaner insulin pump. It's likely the comp…
