Did you know that the Milky Way is even milkier when viewed from the Southern Hemisphere? This is because from the southern side of our planet, we get a clearer, more direct view of the dense galactic core. Here’s a look at the Milky Way starting over the Southern Ocean (between Australia and Antarctica) from our SpaceX Dragon window, complete with some aurora (Southern Lights) and fleeting Starlink satellites. Enjoy the view!

Yesterday’s bone density scans. This DEXA (Dual-Energy X-ray Absorptiometry) machine uses low dose X-rays to measure bone density and body composition. Without the loading signal of gravity, our bones will leach calcium in space, which can lead to significant losses in bone density. This is why it is so important for us to exercise in space. Thanks to lots of weight lifting on the International Space Station, the preliminary results show that the bone density in my spine actually increased in space!

Another peek at our return to Earth last week, just after our capsule splashed down and we exited the helicopter. I was able to walk and even navigate some obstacles. Things got a bit trickier when the scientists challenged me to close my eyes and try a heel/toe walk (like a “walk the line” sobriety test) as you saw in the previous post (but that can be tricky for anyone, try it!). We still remember how to walk when we return to Earth, but our balance and stability can be challenged as our neurovestibular system readjusts to gravity. Although everyone’s recovery is different, it comes back quickly. From floating to walking in a few hours is a crazy transition, but it got even easier when I got back to Houston and was supported by my daughter’s hand!

Last week we wrapped up our training at SpaceX - Crew-12 is certified for flight and ready to go to the International Space Station! We’ve now entered quarantine and are prepping our families and logistics. We’re L-13 days from launch at the NASA's Kennedy Space Center! It has truly been an honor to work with this team - I love it when a plan comes together! Photos courtesy of SpaceX

Pure joy! That’s what I was feeling when I saw my family and friends gathered together to “wave across” to Crew-12. A huge thank you from the bottom of my heart to those gathered here (and elsewhere!) for your love and support!

Crew-12 launch rescheduled due to weather, now no earlier than Feb 13. Yesterday we had our dress rehearsal to ensure everything was just right, including pressing the “SPACE” button in the launch tower elevator (zoom in!) and leak checking our suits. We’re ready to go, hopefully in just a few days! Stay tuned!

Four years ago yesterday the Soyuz capsule carrying ЦПК им. Ю.А.Гагарина OlegSkripochka, @AstroDrewMorgan and me touched down back on our home planet. Reflecting now on our incredible mission, and how much my life has changed since then. Squeezed inside our capsule like a baby in the womb, I can’t help but see the parallels. The 2 most significant figures now at my side, my husband Duke Brady and our baby girl, only came on the scene after the “soft landing” of our Soyuz. You never know what life will bring your way! #Family

Room with a view. Check out my new digs as I camp out in Dragon until our departure. With Crew-13’s arrival we have a very full house on the International Space Station. Luke is living in my previous crew quarters, and I’ve pitched a tent in Dragon.

First week back on Earth, a brief recap. Busy times with science, medical tests, physical training and of course a very joyous family reunion. Missing weightlessness, but loving Earth!

When our NASA Artemis missions land on the Moon, we need to be ready to take manual control for a successful landing. For the Manual Piloting study, I flew this landing simulator before and immediately after spaceflight to assess if any changes associated with cognitive function or gravity affected my performance. Thankfully, I was able to land successfully even just two hours after we splashed down!

Perspective is everything. 🌍 Gazing down at Earth from above offers an incredibly profound one, as does looking back at the International Space Station from a window in the Russian segment. Our crewmate Anna Kikina captured this incredible footage during Anil Menon and my spacewalk on Aug. 6. Even suited up in our bulky spacesuits, we look like tiny little worker bees at the hive given the massive scale of the station.

Ain’t nothing gonna break my stride (except for maybe gravity!). Here’s a peek into our first International Space Station post-flight data collection session, immediately after landing in the helicopter after our SpaceX Dragon splashdown last Thursday. The heel toe walk with eyes open was doable, but definitely off my balance game once they had me repeat with eyes closed (shown here). Exponentially better performance even just the next day, such an interesting recovery process! Stay tuned for the week’s recap of science and rehabilitation.

Volume up and get your groove on. A bit of weekend dancing on the International Space Station to start your week off right. A friend of mine was shocked when she realized that it was possible to dance in microgravity. Seems we can’t keep this from the world for any longer! The power of music transcends Earth and space.

I‘ll stop posting timelapses of the aurora from the International Space Station when I’m tired of looking at them . . . so basically never! Another unforgettable display of this ethereal phenomenon as it danced beneath us last night, this one even more special as it was shared with Anil Menon, as he witnessed it for the first time with such intensity. The red wavelengths (above the green) were particularly bright in this pass.

A whole new world, volume up! That’s me on the tip of the Canadian Space Agency Canadarm in last week’s spacewalk. The ground team dubbed it the Disney Land ride, given the long trajectory of motion from one worksite to the next. This IRL version of space mountain certainly delivered. At times I faced away from the International Space Station, not able to see any of its parts, nor that of the arm. It felt as if I was simply levitating above the majestic blue gem we call planet Earth.

On my first mission I completely fell in love with space photography - tough not to when you’re graced with this kind of unique perspective of viewing all that Earth has to behold from above. I’ve been so happy to bust out the array of impressive lenses that we have up here once again, and this time with even better cameras (Nikon Z9, vs the D5 from my previous mission). I was lucky enough to capture some pretty good aurora (northern lights, here over Alaska and Canada) on my first timelapse attempt of the mission, stay tuned for more! Hoping for some impressive solar events to put on a fascinating show like the ones a few months ago.

Nice catch, Reid Wiseman! From our shared legacy of almost 26 years of a continuous human presence conducting science and technology demonstrations on the International Space Station to the successful return to the Moon with the Artemis II mission, all of us at NASA are so excited to have entered the NASAArtemis era. We explore together as one humankind.

A timelapse view from our SpaceX Dragon of the spectacular southern aurora seen in yesterday’s post, a result of a recent solar event. As opposed to the previous aurora I’ve seen, this one danced and snaked its way directly below us, putting on quite a show. I am in awe of this ethereal and emotionally evocative phenomenon.

You asked for it, and you got it! Behold the making of a space cake, РОСКОСМОС cosmonaut style! Our crewmate Andrey Fedyaev made this video capturing the process, using sweetened condensed milk, layers of intricately sliced honey bread and yogurt (РОСКОСМОС food supplies) and rehydrated berries (NASA food supplies). Our crewmates are such “space kitchen” masters, that I’ve eaten far more cake on the International Space Station than I do on Earth! Each homemade cake is unique, of course (another beloved ingredient is pine nuts!). This one happened to be for my birthday last week. Thank you to all of the Expedition 74 crew for making it such a special event! 🎂🎉

Sneak peek at what it looks like to set up a new experiment on the International Space Station! I installed hardware in the Microgravity Sciences Glovebox (MSG) for the Colloidal Solids experiment. This study will investigate the structure and dynamics of crystal, gel and glass phases during solidification of colloids (mixtures in which tiny particles of one substance are scattered throughout another, but that don’t dissolve or settle out, for example, milk, mayonnaise, and fog). Since gravitational forces often perturb these materials, we may observe differences in microgravity. This research could lead to the development of new materials for space exploration (substrates for plant growth, 3D printing, etc.), and may provide insight into protein crystallization, a critical process in the manufacturing of pharmaceuticals, to directly benefit human health back on Earth.

Yesterday’s science. Started the morning with a blood draw to analyze what has changed in my body from our time on the International Space Station (17 tubes! 16 shown here), while wearing a temperature monitor (the stylish headband) for 36 hours, followed by a study to understand what happens to neck muscles and their control while in space. Gravity is still feeling overrated, but I’m happy to contribute to this important science!

Curly-haired crew, this one’s for you! 🌀🚀👩🏻‍🦱 Join me in my temporary home on the International Space Station, where curls are even more free to be what they want to be. Ever wonder how I care for my curls in space?…where my Earthly 3a curls become more like 3c, my hair finds every piece of velcro it can, and I STILL don’t need a brush! There are definitely some major pros to my space hair, like not having to put it up when I work out. 💪 I’m looking forward to an Earth shower when I get back, though. 🚿🌎

Looks like Mother Earth is putting her best face forward for Earth Day with some spectacular Aurora Australis, or Southern Lights! I couldn’t look away from the International Space Station cupola window as I witnessed this magnificent Earthly phenomenon dance its magical ballet. Covering a majority of the area I could see, our precious blue gem had turned completely green! Mother Earth is undeniably gorgeous, but she is also utterly fragile. Let’s remember to treat her as well as she has treated us. I never saw anything near this scale during my previous mission here on the ISS. That’s because we are currently near a strong peak of the solar cycle, while my first mission coincided with solar minimum.

Another glimpse inside the International Space Station Life Sciences Glovebox (LSG). It was time to provide the neocartilage mentioned in last week’s post with some fresh nutrients, so yesterday I conducted a media exchange. This nifty chamber designed for space has septa on each side, so I can attach 2 syringes – one to withdraw the old media, while simultaneously injecting fresh media. The glovebox helps us prevent contamination in the chamber and also protects us and the space station atmosphere from any potentially harmful chemicals.
