A tale of two gloveboxes: I’ve worked in both of our science gloveboxes recently - with metal studies in one, and immune function research in the other. Sometimes we simply swap samples that are monitored on the ground, and sometimes we’re more hands-on with the science.pic.twitter.com/2TzUOUohKx

I can’t wait to welcome water bears to the @Space_Station! They’ll be flying to station aboard the next @SpaceX commercial resupply launch, along with many other science experiments. https://www.nasa.gov/mission_pages/station/research/news/spacex-22-research-highlights …pic.twitter.com/nnXeb0Qole

Last week’s fire science was cool! I worked on our Combustion Integrated Rack, getting it ready for a continued study of cool flame chemistry. What we learn could lead to cleaner burning and more efficient internal combustion engines. https://go.nasa.gov/3onOwai pic.twitter.com/IQNK36vuMa

.@Astro_Mike I remember we went from shivering on the flight deck (due to cold soak before re-entry) to roasting in the Edwards sun in a short span of time! What an awesome flight on an amazing vehicle! Great flying with you #SpaceBrother! https://twitter.com/Astro_Mike/status/1396892112868741123 …pic.twitter.com/bJzEIdT84T

Went into the BEAM (Bigelow Expandable Activity Module) to get some hardware nearly 5 years after its first opening. BEAM was attached to @Space_Station for an initial two years to demonstrate the expandable technology, and we've kept it to use for long-term storage ever since.pic.twitter.com/5CbbQ9edEH

On @Space_Station, Solar Beta Angle determines how much time we spend in sunlight. Right now, it's almost all the time – which means lots of great ISS viewing opportunities on Earth!

I had so much fun talking with @RobRangers today! Thank you for your great questions. Stay curious! https://twitter.com/RobRangers/status/1393242445983408128 …pic.twitter.com/LFJ2DgBHoN

.@astro_kimbrough moved in the next experiment, SUBSA-BRAINS, which looks at brazing in microgravity. Brazing, a technique that bonds materials at high temperatures, could be used to construct and repair vehicles and habitats on future space missions. https://go.nasa.gov/2IAHUFm pic.twitter.com/JKZILAXj4I

Turns out, hanging from the "ceiling" like a bat is sometimes the best way to work!The Microgravity Science Glovebox is a contained area for liquids and combustion studies on @Space_Station. I removed one experiment and cleaned out the glovebox so the next study could start.pic.twitter.com/mmi7nac3Fw

Well, I had to put it down somewhere! https://twitter.com/Astro_Mike/status/1392917245312081921 …pic.twitter.com/1gglNOtI0X

.@Astro_Sabot and I are conducting an experiment called Celestial Immunity, which studies how gravity affects functional immune response. It could uncover new immune pathways useful for the development of new vaccines and drugs to prevent and treat diseases.pic.twitter.com/2q1qgCa8Lv

I didn't "grow up" doing the kind of lab work I'm doing on @Space_Station, so I'm glad to have an expert on the ground looking over my shoulder and talking me through it!pic.twitter.com/exWLnC0BOP

Happy Launchiversary to my original #SpaceBrothers. I miss you guys! #STS125 #HubbleHuggers @NASAHubblepic.twitter.com/pLBAwaEnjb

We love trains in my family! One day I will take my son to see the reenactment at #GoldenSpike, and we are definitely going to chase down #UP4014 when I get back on Earth. Cheers to the Steam Crew that restored Big Boy Locomotive 4014 in time for the 150th Anniversary!pic.twitter.com/bJAeOGFmMF

Happy #TrainDay! This marks the 152nd Anniversary of the completion of our nation’s 1st #TranscontinentalRailroad. I honor the diverse, immigrant workforce that made this tremendous feat of engineering & innovation possible! Photo of Great Salt Lake was taken by @astro_christina.pic.twitter.com/e0xZjY7cpk

Looking forward to talking with Bruin Engineers at @UCLA tomorrow! I had a few moments to try to capture Los Angeles from the cupola yesterday as we flew overhead, and luckily found the heart-shaped campus right in the center of my shot!
