The Flight Support Equipment (FSE) departs into the blackness of space. The @csa_asc robotic arm jettisoned it a month after it carried two @Space_Station Roll-Out Solar Arrays during their launch on @SpaceX CRS-28. A couple weeks ago I was crawling around the outside of that thing!

Working with @Astro_Alneyadi to change out an avionics unit deep inside our treadmill. She’s back up and running, pun intended.

Victory. @Astro_Alneyadi and I successfully opened the Node 1 zenith hatch on @Space_Station, which we discovered had a jammed hatch handle. Good thing I’ve had practice locking my keys in my car many times.

Working with Steve Bowen to release a Roll-Out Solar Array from its launch carrier and install it at the 1A power channel on @Space_Station. As Frank Rubio and @Astro_Alneyadi flew the @csa_asc Canadarm2, Dmitry Petelin captured this time-lapse.

My first EVA (Extravehicular Activity) was an incredible life experience. The team in mission control @NASA_Johnson was superb. The 1A power channel is now 10kW more powerful. Looking forward to doing it again this week.

Our Astrobee robots are super cute. Testing out some software for an upcoming @ZeroRobotics competition run by my alma mater, @MIT.

A few weeks ago we fixed the Carbon Dioxide Removal Assembly in the US Lab onboard the @Space_Station. It was great to have the additional scrubbing capability as we welcomed the @Axiom_Space-2 crew onboard.

Is this raised terrain, or a canyon? Hint: @GrandCanyonNPS might know the answer. Viewing angle and sun angle create some spectacular visual illusions.
