Andreas Mogensen returned to Earth in mid-March after a six-and-a-half month stint aboard the International Space Station. To mark his tenure as part of NASA’s Crew-7 mission, the Danish European Space Agency (ESA) astronaut has shared his souvenir from undock day—a guided video tour of the ISS.

It’s been a month now since I left the International @Space_Station.

One of the very last things that I did on undock day, was film a tour of the Space Station. It is as much a keepsake for me as it is a way for me to share the wonder of the International Space Station with you.… pic.twitter.com/oFR0VXR06A

“It’s been a month now since I left the [ISS],” Mogensen posted to X early Friday morning. “… It is as much a keepsake for me as it is a way for me to share the wonder of the International Space Station with you. Whenever I will miss my time onboard ISS, and especially my crewmates, I will have this video to look at.”

Mogensen began his show-and-tell in the space station’s front end, above which a docked SpaceX Dragon craft awaited to take him home on March 12. On his left is the roughly 114-by-22-foot Columbus module—a science laboratory provided by the ESA back in 2008. Across from the lab is the smaller Japanese Experiment Module (JEM), nicknamed Kibō, which arrived not long after Columbus.

From there, Mogensen provides a first-person look at various other ISS facilities, including workstations, storage units, bathrooms, gym equipment, multiple docking nodes, and even the station kitchen. Of course, given the delicate environment, that module looks more like another lab than an actual place to cook meals—presumably because, well, no one is actually cooking anything up there.

But the most stunning area in the entire ISS is undoubtedly the cupola, which provides a 360-degree panoramic view of Earth, as well as a decent look at the space station’s overall size.

Speaking of which, Mogenen’s video also does a great job showcasing just how comparatively small the ISS really is, even after over 25 years of module and equipment additions. At 356-feet-long, it’s just one yard shy of the length of a football field, but any given module or transit space is only a few feet wide. Factor in the copious amounts of cargo, equipment, supplies, experiment materials, as well as the over 8-miles of cabling that wire its electrical systems, and it makes for pretty tight living conditions. Near the end of Mogensen’s tour, it only takes him a little over a minute to glide through most of the entire station back to his original starting point.

Of course, none of that undercuts one of humanity’s most monumental achievements in space exploration. Although the ISS is nearing the end of its tenure (it’s scheduled for decommission in 2031), Mogensen’s keepsake is a great document of what life is like aboard the habitat. But for those now looking for an even more detailed tour, there’s always NASA’s virtual walkthrough.
