Fantastic place, occupied by amazing people, working for all of humanity. I’ll forever cherish the memories of serving on the International Space Station. Now, though, I’m thrilled to be back on Mother Earth!

The good ship Piers Sellers, named after a very good man, launches today. I’m very grateful to have crossed paths with Piers and proud of what he stood for. His good-natured humor and ready laugh will never be forgotten.

Beirut & snow-covered mountains to the East, taken on Feb 12, 7:20 AM local. I’m going to miss being able to glance out the windows and see views like this. Such a beautiful planet.

Shockingly bright as I opened our shades, the Moon lingered, strutting by. Lots of time to find good camera settings! Soon we’ll be exploring our neighbor again.

One of these Astrobees is not like the others. Last week, Kayla joined in on the fun with Bumble Bee and Queen Bee, two Astrobee robots doing some test flights on the @Space_Station.

I looked back at my journal entries recently and thought I would share... Day 1: “It was a bit jarring going from crowds and outdoors to indoors, few windows, and few people [on the International Space Station].”

Day 200: “Last night, I went to bed after the hatch closure, but before Oleg, Yulia, and Klim actually undocked. … Today [a day off] for me will be a very relaxing one.”

(1/2) @NASA's Day of Remembrance is one of mixed emotions for me. It reminds me of the tragic loss of some absolutely wonderful people. Yet that loss heightens my sense of gratitude for the wonderful people, friends, with whom I have the privilege to work right now.

Going with the flow 💧 In space, we get a unique look at fluids, and we’re taking advantage of that in @Space_Station experiments! Researchers use surface tension to study diseases in microgravity and examine small capillary forces controlling liquids.
