During my last flight I was intrigued by the #storyofwater evident in views all over the Earth. Water is amazing stuff. It can sustain life and level mountains. Here are a few more pages in that book! Glaciers in Central Asia.

I love our #Crew4 mission patch. I love that my daughter created it!
"My dad has always been one of the biggest supporters of my art," says Alexandra Lindgren of dad @astro_kjell. The @TAMU student designed the patch for @NASA @SpaceX #Crew4, which is on the @Space_Station. More on the ultimate dad/daughter moment tonight on #khou11 at 10.

A quiet Memorial Day on the @Space_Station. Humbled by the sacrifices made by men and women of our armed forces in service to our nation. A salute to fallen friends, classmates, and servicemembers and a prayer of peace for their families.

Congratulations Scott! Can't wait to read it!
The power of inspiration cannot be measured by the deeds of the uninspired but by the achievements of children as they realize their dreams. Excited to share what I learned from my path to space & how to launch your own dreams in my new book! bit.ly/3EccQ75

On April 7, the #Crew4 astronauts entered their official quarantine period in preparation for their flight to the @Space_Station! Spending this time in quarantine will help ensure the crew is healthy, protecting themselves and those already on station: go.nasa.gov/3v8UnEh

Thank you @CUAnschutz @CUMedicalSchool for providing the launch pad for this amazing journey. So grateful to instructors, mentors, classmates and patients for their support and trust. It was a profound privilege to care for people in their time of need.
.@astro_kjell, CU Anschutz’s first astronaut, credits the @CUMedicalSchool for playing “a tremendous role” in helping him achieve his goals of becoming a physician-astronaut.👏 🚀 👨‍🚀 #NASA | @Space_Station bit.ly/3DR9YfO

Through the Commercial Crew Program, NASA and SpaceX have restored a national capability and we honor the ingenuity and hard work of those involved. Alan Shepard flew on Freedom 7 at the dawn of human spaceflight. We are honored to bring Freedom to a new generation! 2/2
