This is how I make my star trails. Sequences of still images assembled until the beauty of Earth from International Space Station reshapes into a new form by the forces of time, nature, and physics. Thanks to Christopher Malin for making this video clip from my Expedition 30 photographs.

New star trails photography is back! This 30-minute time exposure through orbital night with our new 15mm wide-angle lens was able to capture sunset (on the left) all the way to sunrise (on the right). I have never been able to capture this before but our new fast (14mm f1.4 and

Wow! What an incredible shot by Cassini !

A new spin on orbital video.

In space, you can see stars! I flew a home-made tracking device that allows time exposures required to photograph star fields. Stay tuned for more photos like this.

C'mon. You know that you have thought about this. 😏🚀🤿 #Europa #EuropaClipper ARCHIVED - NASA Europa Clipper ESA's Juice mission #SCUBA #Astrobiology

The first air crash investigation on another world has concluded that the crash of the Ingenuity helicopter on Mars was caused by the inability of the navigation system to track the relatively featureless terrain. This resulted in a touchdown with too much lateral velocity,

Getting ready to watch Blue Origin launch New Glenn for the first time ever, with Everyday Astronaut keeping me company

It was an honor to speak to BBC about my research on Molten Regolith Electrolysis. One day, this technology could be supplying oxygen and metals, enabling future human space exploration of the Moon and Mars!

Incredible to see Fast Company covering our research on Molten Regolith Electrolysis!

WOW, instantly one of the coolest space videos I've ever seen. This is Firefly Aerospace's lunar lander, headed away from Earth and towards the moon.

Wow! What a cool experiment from Don Pettit !

We love fluids in microgravity!

JFK gave multiple answers to "Why the moon?" in his 1962 speech. But the one that means the most to me is least quoted Not "because it is there" Not "because they are hard" But "Because that goal will serve to organize and measure the best of our energies and skills" #Apollo11
