Spacewalk Tomorrow

Tomorrow morning I will be getting up at 4 AM to go in early for my day shift at ISS mission control. I am assigned to the regular day shift from 7 AM to 4 PM all week. It just so happens that the first shift is the same day as a Russian ISS spacewalk. Cosmonauts Fyodor Yurchikhin and Aleksandr Misurkin will perform the 33rd Russian spacewalk onboard ISS. You can read all about what they will be working on over at

While I will be working a long 11 hour shift starting early in the morning, I am definitely still looking forward to it. This will be my first time in the Flight Control Room for a spacewalk. I previously supported from the Multi-Purpose Support Room for US EVA 20 last fall, with a more experienced flight controller in the ADCO seat. Being assigned a shift as ADCO for an important event like a spacewalk is definitely a lot of responsibility to take on. But ADCO has relatively little to do for most spacewalks when compared to many other flight controllers and support personnel who have a direct responsibility to the safety of the crew and the tasks being performed. If my ADCO team does our job well tomorrow, we will actually do and say very little for all 11 hours we are there.

One important task we have is to send commands related to disabling the Russian Segment thrusters late in the EVA. There are some maintenance tasks that will take the cosmonauts close enough to the back end of the Russian Service Module that flight rules dictate all thruster valves closed for safety reasons. We will be monitoring the spacewalk progress closely to make sure we are ready for disabling thrusters as needed.

Other than that, it will be an exercise in listening and patience. I would say it is an exercise in bladder management also, but at least I am allowed to leave the room briefly for breaks during the spacewalk. The cosmonauts will have to go probably close to 8 hours without food and bathroom breaks. And that’s why I’m not complaining about my 4 AM alarm. Bring on the shift!
