It’s a great honor to be nominated by to support and help lead NASA. The agency is critical in America’s fight to combat climate change and maintain leadership in space.
Today marks the beginning of #WorldSpaceWeek! Join in celebrating this year’s theme: women in space.
Sally Ride became the 1st American woman in space in 1983. She was my hero! And in just a few years we’ll build on her legacy – landing the first woman on the Moon!
Did you know that it’s a woman who holds ’s record for spending the most cumulative time in space? Having spent a total of 665 days in space, Whitson is a role model for #WomenInSpace everywhere. #WorldSpaceWeek
Just two years ago, Meir and Koch performed the first all-female spacewalk in ’s history. They successfully replaced a broken battery on the International during their historic time in orbit. #WomenInSpace #WorldSpaceWeek
Happy #NationalAviationDay! 100 years ago, Bessie Coleman became the first African American woman to earn a pilot’s license, paving the way for so many other explorers.
As a woman test pilot and astronaut, I stand on the shoulders of giants like Bessie Coleman.
.'s leadership in exploration continues to give me great hope for the future. The outstanding members of the NASA Advisory Council will inform key decisions to maintain NASA's position as a global leader.
Congratulations to the new members!
The decade ahead is crucial for Cislunar space and the Moon's surface. Just after the Artemis I launch, we’re excited to see 's first national science & technology strategy to support responsible, peaceful & sustainable exploration of Cislunar space!
Behind each astronaut are thousands of people on Earth working to ensure the safety of the crew.
My friend Travis Thompson exemplifies ’s excellence, and how every member of the NASA family is integral to our missions’ success.
The booth at #IAC2021 is officially open!
My favorite part: The 1:25 model of the SLS Moon rocket, set for launch from KSC in February 2022.
The other show stoppers are award-winning photos by and video featuring our 5 mission directorates 🚀🌎👩🚀
As moves forward with plans to send astronauts to the Moon under Artemis missions to prepare for human exploration of Mars, we're calling on U.S. industry, academia, international communities, and others to provide input on our deep space exploration objectives.
Mary W. Jackson was the first female African American engineer at and a pioneer for #WomenInSpace. Her influence led to the hiring and promotion of so many women in STEM.
In 2020, our headquarters in Washington, D.C. was named in her honor! #WorldSpaceWeek
As an veteran, test pilot, and astronaut, 9/11 was a deeply personal tragedy. The effects of the terrorist attacks are embedded in our national identity – we will never forget. 20 years later, the threat has evolved and it's more important than ever to remain strong and united.
As we celebrate the 40th anniversary of Sally Ride's historic first flight as the first American woman in space, we pay tribute to her pioneering spirit. Her journey challenged boundaries and ignited the imaginations of millions. Today, we carry her legacy forward.
I so appreciate my colleague and friend introducing me at hearing for Deputy Administrator. Excited to work together again!
We need a Moon to Mars roadmap with staying power to achieve our exploration goals, and we have our objectives.
With thoughtful input from our workforce, industry, and international partners, read more here on how we will shape our future together:
Wonderful to see the successful docking of ’ new #Nauka laboratory module! Nauka and the European Robotic Arm it’s carrying will help us uncover even more discoveries aboard the International !
I am thankful for the family and all of the work that they do to push the boundaries of space exploration and to benefit humanity.
Happy Thanksgiving, and may we all take a day to give thanks, express gratitude, and spend time with our families and loved ones!
So cool to visit to see Dreamchaser! We discussed our collaborations and technologies in low-earth orbit that will help humans develop a robust Low Earth Orbit space economy!
My friend Travis Thompson was lead of launch day support for my mission as a spaceflight commander and for many others.
I was honored to celebrate his legacy as his Closeout Crew suit was added to the Discovery collection at !
The #Inspiration4 launch is one outcome of our nation’s partnership with private industry. Creating a sustainable economy in low-Earth orbit including commercial transportation to space for people & crew and commercial space stations is critical to our future on Earth & in space.
On this Day of Remembrance which marks the 55th anniversary of the Apollo I tragedy, honors the lives lost in pursuit of discovery including Challenger & Columbia.
May we continue to honor their legacy by putting safety at the forefront of our exploration for all humanity.
What a historic milestone! Congratulations to Mark Vande Hei for claiming the record for the single longest spaceflight of a U.S. astronaut!
At 341 days, he surpasses the formidable and will return having logged 355 days aboard the .
