We’re doing some exciting science up here with partners from all around the planet, but a pause over last weekend allowed Nicole Mann and me to use European Space Agency’s GRIP experiment chair for a slightly different purpose--we even managed not to make a mess.

I've voted my entire adult life, but this year’s voting booth definitely takes the cake. So thankful to everyone – especially Democracy – for allowing me to remain part of this essential process this year.

.Nicole Mann flew a great approach to capture NG-18, the SS Sally Ride, bringing Exp 68 required EVA hardware just in time for the 11/15 spacewalk, all kinds of exciting science, essential provisions, and even some fresh fruit and cheese which we haven't enjoyed in over a month!

Earth's thin atmosphere was penetrated by the last rays of an orbital sunset as the International Space Station flew 258 miles above our home planet. More images from Tuesday's spacewalk: go.nasa.gov/3Igjcmj

Us, coming home after a long day at work last week. Later I took my family on a video tour inside the ISS. When she saw my spacesuit, my wife hollered, “Thanks, suit!” Yep, and also thanks to the many, amazing people who train us and safely execute the plan from Mission Control.

Open-shoulder surgery on a spacesuit with Nicole Mann — thanks David Saint-Jacques and the entire Mission Control team NASA's Johnson Space Center for the assist. Patient is doing well after a complete checkup, with a trip out the door likely in the next few days. Telemedicine works!

Made a great pass over (sunny!) northern Michigan yesterday as my family was actually down there skiing. I sent these shots to my kids and told them, “Good luck with the Space edition of ‘Where’s Waldo?’”

As our stay aboard this amazing, orbiting laboratory comes to an end, here's a look back at a bunch of the science we've conducted during this mission.

I agree, Paul Rudd -- the world of quantum physics is absolutely fascinating. During the night, I loved floating by the Cold Atom Lab, seeing it all lit up, humming along. I would always smile and think, “Just the Universe, doing her thing. Through quantum mechanics. Per usual.”

Having the opportunity to talk to students across the planet via ham radio while aboard the International Space Station has been a huge highlight of my time in space. Their enthusiasm, riding those long electromagnetic waves, was completely contagious.

With the support of so many incredible people over many years, we all accomplished the mission: we left the International Space Station and human spaceflight a little better than we found it. Thank you. With that, please consider this my out-of-the-office for a while.

So grateful to the men and women who make human space flight happen — and who helped this Midwesterner make my contribution. But now it’s time to hang up the space boots (or just let ‘em float there) and embark on a different kind of exploration. I’m incredibly honored to have

So fired up to be part of the Quantum Opus team (quantumopus.com), changing the world. One photon at a time. finance.yahoo.com/news/illuminat… This is not a lightsaber. Well, kinda.
