An incredible mission investing in our youth. Setting seeds of inspiration that will help excite a new generation of space explorers and leaders. Midland, Texas is home to one of our nation’s space ports.…
Wow, that’s amazing! Thanks for sharing. Wish the AX-1 crew well!!!…
Seems like yesterday, but 14 years ago, today, we launched @sts-123 to the @Space_Station! We had four rookies onboard that night: @astro_g_dogg, @AstroBehnken #mikeforeman and myself. What a memory!!!
Sounds like it will be an interesting discussion! I’m planning to listen in on Friday.…
On the 52rd anniversary of the Apollo 11 landing, AND after an awesome weekend in Wapakoneta, OH where ~600 runners ran 5K/10K in the “Run to the Moon,” I registered for this @VirtualStrides event. 5K - I’m up for it! Congratulations @HigherOrbits for all your recent successes!…
Congratulations to the @blueorigin team for an historic first flight with humans onboard in New Shepard this morning!
Great topic! It will be an interesting and timely discussion.…
Welcoming #Unity22 to space -- and home again. No matter where you go -- there you are! A simple diagram doesn't do justice to the hard work on the part of the @virgingalactic team and #VirginFamily that it took to make today happen. Congratulations -- and welcome home!…

Well stated @AstroIronMike! It was a pleasure catching up with everyone (including spouses) this week! A great memory!…
My answer to Does NASA give each astronaut poison pills in case they are captured by alien or contaminated by alien life forms? If governments give spies such protection, wouldn't it make sense for astronauts to also carry these around?…

Ten years ago today, I launched on my fourth and final mission to space. It was a heck of a ride, and I’ll always be grateful for the amazing people at NASA who supported me along the way.

#NationalGeographic published a nice article on the #Shuttle with sound bites from a couple of my #STS-134 crewmates incl @Astro_Taz and Roberto Vittori. #NatGeo brings incredible stories of #exploration and adventure to our classrooms and living rooms.…
#STS-134 launch 10 years ago. We strapped in before sunrise on 5/16/11. A crisp morning w calm seas. On our backs in anticipation, at 8:56 am EDT, the serenity was suddenly disrupted by the rumble of main engines; followed by SRB ignition: a violent start to an amazing adventure!
Just so happens the Dr Joe Dervay, our #STS-134 flight surgeon, stopped by the festivities tonight. Couldn’t resist sending another Tweet as our worlds collide on the 10th anniversary of #Space Shuttle Endeavour’s final trip to space.
Night before #10th_anniversary of #STS-134 #launch. We had a crew family get together at the beach house at #KSC, before final quarantine. Just so happens that ascent Flight Director Richard Jones and I were reminiscing about it tonight at the Johnson place.
L-2 to the 10th anniversary of #STS134 launch. I just spoke about the flight to an elem school today in Midland Texas (in person for the first time in over a year!). So much curiosity and energy from the kids. This photo is a favorite. Taken right after our first scrubbed launch!
L-3 for the ten year anniversary of #STS134 launch. @CaptMarkKelly & I each flew a Shuttle Training Aircraft profile on May 13, 2011 to get some last minute training at the #Shuttle Landing Facility runway. It’s 15000’ long and has hosted a majority of the landings over the years
Excited to join @Astro_Nicole @SteveWolfe119 & Jane Poynter from #SpacePerspective on a #UniversalCitizen Webinar next Friday, May 21, at 1 pm EDT. On this free webinar hosted by @spacenation: we will be comparing ideas on the importance of taking care of each other & our planet!
Thanks, Garrett! I was trying to forget to add that extra trip around the sun - they add up! Miss the gang!…
First #STS-134 crew arrival occurred on April 26th via T-38s. After our initial launch scrubbed, we returned back to Houston and pushed the timeline forward a couple of weeks, planning for the final launch of #Space Shuttle Endeavour on May 16, 2011.
L-4 for those tracking countdown to #Space Shuttle #Endeavour’s final launch 10 years ago. We arrived at the cape a second time, this time by #NASA business jet. #STS-134 quarantine continued at Kennedy Space Center.
L-5 & counting for the ten year anniversary of #STS134 launch. In our 2nd day of quarantine, we studied, practiced, bonded, and continued to sleep shift. Thanks to Beth Turner, family support office, for looking after our immediate families during quarantine and the actual flight
Probably two VMS sim runs for every STA run over the years. In total I got over 3000 really high fidelity shots at Shuttle landing as a PLT. All varieties of weather, contingencies, malfunctions, and runway length/width. CDRs got even more.…
STA was the only way to get “real flying” approaches with real vehicle/weather etc. We “went around” at 20’ or so design eye height delta for touchdowns. However, the Vertical Motion Simulator NASA Ames was the highest fidelity for landing malfunctions, bad winds, and short rwys…
L-6 to the #10thAnniversary of #STS-134 launch. With 1 day of quarantine complete, we sleep shifted a full hour to get our circadian rhythms headed for early morning launch. They used light therapy to assist. We flew our last ascent sim with MCC, led by Flt Director Richard Jones
A few days short of 10 yrs ago, our #STS-134 crew chilling out in Bldg 9, #NASA JSC, at suited #Shuttle bail-out training. @CaptMarkKelly, @AstroIronMike, myself, Roberto Vittori, @Astro_Taz, & @Astro_Feustel. Training incl rappelling down from overhead window of Shuttle mock-up.
L-7 days prior to launch of #STS-134 aboard #Endeavour on her 25th and final final flight to #space. We entered 7 day quarantine - starting at #NASA JSC crew quarters & eventually moving to KSC. Final goodbyes to friends/family - short visit allowed by one family member each day.
#AMS Alpha Magnetic Spectrometer was a cosmic particle detector: a collaboration among over a dozen countries to better understand our #UNIVERSE! Dark matter, dark energy, & naturally occurring antimatter. Check it out Over 166 billion particles to date!
L-8 & counting for #space shuttle #STS-134 launch 10 years ago. Our original launch date was 7/29/2010, but we slipped 10 months because of an #AMS (major PL to the #ISS) redesign. @AstroIronMike, @Astro_Taz and @Astro_Feustel were now fully trained for their 4 #EVA spacewalks.
Appreciate the interest out there with our @sts-134 countdown. PROP flight controller Dean Lenort @dllprop reminded me that it was Tony Ceccacci at the helm as Entry Flight Director! After 10 years, exact memories fade, but it was a special segment in all of our lives!
STA = Shuttle Training Aircraft. After our entry sim, @CaptMarkKelly and I flew a pair of T-38s to El Paso where we flew our last modified Gulfstream II Shuttle approach and landing airborne trainer before quarantine. We each got 10 shuttle approaches. Best training available!
L-9 to the #STS-134 launch #10 years ago. Our final integrated entry sim w Mission Control led by FD Gary Horlacher. Later in the day, @CaptMarkKelly and I flew to El Paso for our final STA at White Sands. Info from our crew scheduler Alicia Robinson!…
Today (#10years ago), our #STS-134 crew had recently returned from the Terminal Countdown Test (TCDT) at the cape. All systems are go. Training for the #spaceflight is almost complete. Here is an excerpt of “crew assignments” for various tasks for ascent and docking to the #ISS.
Countdown to #STS-134 launch #10Years ago. L-10 and counting. We got our preflight physicals and inventoried our actual flight equipment/personal gear during the “bench review.” @Astro_Taz, Roberto and I donned our “Actiwatches” to study sleep patterns throughout the #spaceflight
Congratulations to the @HigherOrbits team for doing an amazing job advancing #STEMeducation - even in this #COVID19 environment. #SpaceInspires our youth to reach for the stars! Happy #NationalAstronautDay!…
Happy #NationalAstronautDay! I’d like to acknowledge my colleague and friend @Astro_Wheels. He’s been an active #Astronaut for over 20 years. He’s flown Shuttle, Soyuz, performed 6 EVAs and commanded Expedition 25: tweeting amazing photos from #Space! And, it’s his birthday today
LOL. Our STS-134 crew pose was a “Star Trek” copycat pose (obviously not “Star Wars”), but fun & science fictiony. For the math majors out there: everyone knows there are more than 12 days in 2 weeks - didn’t mean to fib.😎 I’ll tweet more in upcoming days leading to launch day!…3
Happy Star Wars Day! This is a fun time of the year for space enthusiasts around the world. #MayThe4thBeWithYou Exactly 10 years ago today, STS-134 was TWO WEEKS out from launch! @CaptMarkKelly @Astro_Feustel @AstroIronMike @Astro_Taz RVittori and I were ready to go!…
The little rotorcraft that could.🚁💨 Ingenuity documented its historic ascent today. Here's th#MarsHelicopterer's POV during first flight. That's its shadow on the ground belowjm

Today in 1972, Apollo 16 lunar module "Orion" landed on the Moon in the Descartes Highlands. Astronauts John Young (seen here) and Charles Duke were on the Lunar surface for 71 hours and two minutes, while TK Mattingly circled the Moon in the command module "Casper."

What an amazing airplane and flight! I love the folks in the Wapakoneta area and my first time landing at the Neil Armstrong Airport. Typo above - not 1970, 1970s. Year was actually 1979. Lear 28-001 felt similar to flying a T-38. No wonder since the engines are closely related.
Excited to fly tomorrow’s flight on the Lear28 first flown by Neil Armstrong in 1970. He set 5 world records including min time to climb & max altitude (51K) in class. Lear 28-001 will have its final flight tomorrow, donated to the Armstrong Air & Space Museum: lands @ 10 AM EDT.
Excellent job today Wheels, and it was an honor to share today’s events with you and the Fox team.…
I was disappointed at the scrubbed launch of today's 1st flight of the #SpaceX crewed #Dragon to the International Space Station. Weather was not acceptable. Safety first! Tune in on Sat afternoon to witness an amazing milestone for our nation & the world.…
Mike, what a great adventure and memory! 9 years have flown by, and many of us have taken on very different roles, some in far corners of the world. It was an honor to be a part of this tight-knit team of professionals, family and friends who supported this incredible mission!…
