I have no words suitable for the magnitude of destruction in Lahaina, so I’ll just share some raw images. Aug 8 just before the fires started, and Aug 17 during recovery operations. My heart goes out to those affected.

Some details on @JAXA_en's Airlock in the JEM (Japanese Experiment Module), and a quick float over to the PMM (Permanent Multipurpose Module).

It’s been over 6 months since my last training session on the ground. Here’s how @NASA_Astronauts keep current on operating the @csa_asc Canadarm-2.

Welcome aboard, S.S. Laurel Clark
Replying to @NASA
Capture confirmed! Next, the @Space_Station’s robotic Canadarm2 will attach the #CRS19 Cygnus spacecraft to the orbiting laboratory. Our live coverage will resume right here at 7:30am ET (1130 UTC). blogs.nasa.gov/ng-crs-19/

Some typical ops working with our Astrobee free-flyer robots. Footage from last week; just did @ZeroRobotics finals run hosted @MIT today.

Unnamed storm brewing in the South Pacific last week. The @Space_Station provides an incredible platform for monitoring extreme weather events around the world.

We’re not *always* weightless on the @Space_Station.

Llullaillaco at the border of Chile and Argentina. Nerding out on geology. Check out those lava flows!

My second spacewalk: upgrading the 1B power channel with an ISS Roll-Out Solar Array. An even better time-lapse from Dmitry Petelin.

The amazing @ZionNPS from the @Space_Station. Zoom in and you can pick out Angel’s Landing.

Atmospheric density exponentially decays with altitude, but the decay rate at orbital altitudes depends on solar activity, making long-term predictions difficult.

One correction: I said off the cuff the orbit would decay over the coming days to weeks. It’s actually years – reentry timing has high uncertainty, but estimates center around summer 2025. Primary driver of orbital decay is drag from tiny remnants of Earth’s atmosphere.

Jettisoning @Space_Station hardware we no longer need with the @csa_asc robotic arm.

Give me that which I desire. This #InternationalDayofRock, @Metallica is adding "Fuel" to the fire of our #Artemis missions to the Moon.
