4 of 4 - ‘Gone Fishing - Artemis Style’ – keeping a sense of humor and finding the joy that is in everything, is the way to make your way through stressing and challenging things. So what do you do when you make an emergency landing here on Earth, far from the recovery forces… and your spacecraft ends up in the upside-down? Go Fishing! Thanks to one of our @NASAArtemis team who brought the toy fishing poles, we were able to have a moment of fun for everyone that kept the stress levels low prior to focusing on the seriousness of the training we had to accomplish.
3 of 4 - With our egress path being out the docking hatch which is submerged underwater, we have to partially flood the capsule by opening and removing the docking hatch. As you can imagine, this is not a comfortable feeling letting water into the space which in real-life would be your only breathable air (in this case the trainer is not a sealed vessel). Then we have to take our survival kits, life raft and medical kits – make sure the equipment and crew are tethered together so we don’t get separated and then take a deep breath, drop out the bottom of our floating Orion, and swim up to our raft on the surface. Just another great day of training for @NASAArtemis III crew!
2 of 4 - In order to train for this deep contingency case where we are stuck upside-down and are not close to any of the recovery team that has the backup uprighting system, we train to get out underwater. The trainer (with us in it) is hoisted over the water and rolled to the upside-down position so we are hanging by our restraint straps. Then it is partially lowered into the water to the level we would expect it to be floating after a mission.
1 of 4 - What do you do when your @NASA_Orion spacecraft spashes down, turns upside down and cannot upright itself? @NASAJohnson Neutral Buoyancy Lab, we can train for that. First - @NASAArtemis III crew makes a plan, huddles up and then ingresses the Orion trainer capsule.
‘Taking Flight’ (nearly). Our beautiful Artemis III Space Launch System (SLS) Core Stage left the surface of the earth (briefly) today as it ‘flew over the hump’ via a giant crane in the Vehicle Assembly Building to be mated between our 2 already assembled Solid Rocket Boosters on the Mobile Launcher. Spectacular job by our SLS, Exploration Ground Systems,and @NASAKennedy team! Go @NASAArtemis III!

It is a beautiful thing to see our @NASAArtemis III boosters taking final form. Seeing them 2 days ago was amazing, talking with the team and being able to thank them for continuing to get it done in record time…. Priceless
The boosters for the Artemis III mission are getting stacked!
Technicians are stacking the twin solid rocket boosters for the Space Launch System rocket at @NASAKennedy. The boosters will provide more than 75% of the rocket’s total thrust at launch — scheduled for 2027.

The perspective of the image is looking up from near the base of the booster. The booster is white, tube-shaped, and has black block-shaped markings near the base. The booster extends upward through several platforms of the VAB. Credit: NASA/Cory S Huston

#NationalAviationDay is time to remember the #FlightSpark that started my aviation journey. Maybe it was during my first flight pictured here when I was 1 ½ yrs old (although my mother said I fell asleep!)
The journey continued as I joined @NASA as an astronaut, where today I am fortunate to fly our T-38Ns at @NASAJohnson.
The journey will continue as we prepare to fly the next @NASAArtemis mission next year. I’ll be flying with @Astro_Luca, @Astro_AndreD, & Frank Rubio on Artemis III. If you are looking for your ‘spark’, come to @NASAKennedy for NASA.GOV/maxpower and see what American @NASAAero, Military, Spaceflight, and Technology will be showcased that might ignite the spark for your next journey!

Later this year, we'll be holding an event at @NASAKennedy to showcase American leadership in aviation, space exploration, and emerging technologies. Join us for a sneak preview on Friday, Aug. 14: go.nasa.gov/4fznPfi

Don Pettit, the Obi-wan of space photography!
I finally have all 1.2 million raw image files from my latest mission to ISS! Here is a sample of one of my favorite Milky Way photos, taken from the Cupola with Nikon Z9, Arri Zeiss 15mm lens, T1.8 with custom sidereal drive that cancelled out star motion relative to our orbit.

There is something really special about being reunited with hardware you have flown with in space. This 4th and final engine for @NASAArtemis-III, #2048 and I shared 11 days and 171 orbits of the earth together on @NASA Space Shuttle Atlantis, STS-129.
Roadtrip complete ✅
After departing @NASAStennis, the fourth and final RS-25 engine for @NASA's SLS rocket has arrived in Florida.
Now reunited with the other Artemis III engines, the powerful quartet is almost ready for installation at @NASAKennedy.

Today I am in Washington DC for the celebration tonight at the US Capitol televised on PBS and tomorrow on CBS for America 250. I have the privilege of narrating content for both events.
At the moment, I am sitting in my hotel room looking out the window watching our amazing fighter pilots rehearsing their flyover for tomorrow’s 4th of July celebration. I have been on military bases all over the world and seen these jets many times before but experiencing them practicing in the skies over our nation's capital in preparation for our 250th birthday is something quite unique, and special.
We live in a great country. It’s been wonderful to see how folks from around the world who have traveled here for the World Cup are enjoying so many of the things that we are so used to here. We have so much to be thankful for, not the least of which are the men and women who defend our country and protect our cities. Those whose service and sacrifice must not be taken for granted. Where would we all be if no one wanted to serve?
Over the course of our 250-year history, many sacrifices have been made. Thousands and thousands of our fellow Americans are buried in 26 military cemeteries in foreign lands with many more here at home. Each day at the Gary Sinise Foundation we work diligently to serve and honor these sacrifices by supporting those on active duty, those who have served, and the families that serve with them and have sacrificed alongside them.
I have met many over the years and they inspire me each day with their triumphant spirits. America is an evolving idea created by those who chose to fight for independence and freedom against a tyranny. We have inherited that idea, and while there certainly have been many extremely challenging moments in our history, there have been many triumphant ones to celebrate.
In this new video of a song called Triumphant, written by my son Mac Sinise and his pal Oliver Schnee, we include a few triumphant shining moments in celebration of America’s 250th Birthday.

3 weeks after the announcement and still appreciative of the new Astronaut tradition of 'Passing the baton/Passing the torch/Carrying the Fire'. Many more of these and more often with accelerated @NASAArtemis missions!
So grateful and appreciative to be a part of the crew that will be “Carrying the Fire” through the next @NASAArtemis mission! Go Artemis III.
LIVE: Meet the crew of our next Artemis mission.
We're sharing the latest updates on Artemis III: xitter.twitterapi.xyz/i/broadcasts/1DxleekBr…
With Artemis-II safely home, join @NASA for the next giant leap
One week to go! 🚀
@NASA will announce the Artemis III crew on June 9 at 11am ET (1500 UTC). Get ready to meet the four astronauts who will help advance the technologies needed to return humans to the Moon.

If I saw just this picture it would be easy to say it was made in Hollywood, but after having watched #Artemis -1 launch & perform its' test flight so well, so far....it makes these images even more astounding! Godspeed #Artemis -1, looking forward to your splashdown on Sunday!
We have retrieved signal with @NASA_Orion after an expected loss of signal when the spacecraft flew directly behind the Moon.
You can see Earth in the distance. That's us. #Artemis
