Timelapse of the ISS Optimal Propellent Maneuver (OPM)! We use this to reorient station's attitude in preparation for docking events. This one occurred over some magnificent Mediterranean city lights!

A room with a view: The aurora today as seen from the SpaceX Dragon window. Space station is moving foward and the window looks out in the direction of travel. You can make out the window framing. Z9 1/4s 15mm ISO 8000 MP4.

Little things. Captain Jack Hathaway helping the team in so many ways. These scissors open the food packets and he always preps them for tomorrow. Sometimes they sway on their ends like a Forrest of scissors. I love that.

I’ll never forget this sight. Tonight I saw my first aurora from space. Luckily, there is a video to help remember and captured it perfectly. The KP index was over 5 tonight because of a solar event and the sky over Australia lit up and the green snaked across the atmosphere. I was filled with awe and gratitude. It’s a beautiful planet we share.

Crater Lake from the ISS last night. Just past the solar arrays. Even from 250 miles up, you can't miss it — that deep blue caldera, Wizard Island tucked in the corner. But look east of the lake and you'll see the other story: smoke from wildfires stretching across Oregon. Before I was an astronaut, I served as a flight surgeon with the 173rd Fighter Wing at Kingsley Field in Klamath Falls, just down the road from this lake. I spent a lot of good years in that corner of Oregon, and it's hard to watch it burn from up here. Thinking of everyone impacted by the fires — the families who've lost homes, and the thousands of firefighters and aircrews working around the clock down there. From this altitude you see how big the smoke is. You also see how many people are fighting it.

I looked down the hall and saw Anna Kikina smiling as she searched for an item during her workday. Always so positive and has a huge smile on her face that it lifts my spirits up anytime we cross paths.

A day in the life: if the suit fits, wear it. The road to EVA starts 2 to 3 weeks before a spacewalk and involves the whole team at @NASA, including suit engineers, specialists, astronauts, flight directors, among others. In this video, @astro_hathaway explains our first step in that direction.

🫧 @Astro_Jessica and I have a spacewalk coming up early August.  We are preparing this week with the @NASA EVA team.  Step one – get the suit ready.  We are filling and testing the water bags.  After filling it with water, there are air bubbles, but they are not at the top, and the only way to get them out – and get more water in – is to spin them (centrifuge) and then squeeze the air out.  This was my very first attempt at this.  Mission accomplished!

Here is a 360 view of the cupola where I got to spend some time with @Astro_ChrisW, soaking up his knowledge on cameras, stars, physics, and spacewalks. I was his backup for his launch, and now that I am here, he is passing on the knowledge he gained over 8 months on the @Space_Station, including a month as the only US crew member. I’m happy he gets to return but sad to not be able to immediately turn to him for advice on where to find an experiment, or how to organize the work bench with duct tape & ziplock bags, or how to get the perfect shot of the sunset. If you make it to the end of this video, there is a pretty nice one. I sped up the middle section so you can get there faster :) Here’s to our resident astrophysicist Chris Williams!

Expedition 75 is beginning , and I’m excited to get started. It's bittersweet to see Chris Williams leave, however, I'm glad he will rejoin his family, friends, and planet earth. Every expedition brings a new mix of astronauts, flight controllers, managers, leads, and teams behind the mission. For a lot of us, this is where years of work start to feel real.
