Liquid Ping Pong in Space NASA astronaut Scott Kelly, who marked day 300 of a historic year in space on Jan. 21, 2016, shows off another fascinating feature of life in microgravity. Kelly used two paddles with hydrophobic, or water repellant, features to pass a sphere of water back and forth. Scientists use the microgravity environment of the space station to advance scientific knowledge in Earth, space, physical, and biological sciences that otherwise wouldn't be possible down here on the planet. The paddles are polycarbonate laser etched so that the surfaces are actually arrays of 300 micrometer posts (0.3mm). The surfaces were then spray coated with a Teflon coat. The combined effects of surface roughness and non-wettability produce a super-hydrophobic surface capable of preventing water adhesion in dynamic processes. The larger the drop, the less force it takes to break it up. The smaller the drop, the harder you can hit it. Scott is demonstrating about a 4 mL drop (over 100 times larger than a rain drop).

Ever wonder what the spacewalker sees while you’re looking at him or her? Here’s your answer, courtesy of NASA astronaut Jack Fischer. This Ultra High Definition clip shows Fischer outside the International Space Station during a spacewalk on Expedition 51 in May 2017, and the view from a small camera attached to his spacesuit at the same time.

Water in space behaves… differently. Surface tension and capillary flow can be harnessed to move fluids in more efficient ways. What looks like fun could actually help us improve systems for moving fluids in microgravity, in things like fuel tanks for space travel.

While Apollo placed the first steps on the Moon, Artemis opens the door for humanity to sustainably work and live on another world for the first time. Using the lunar surface as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars. ✨ We are returning to the Moon – to stay – and this is how we are going! Actress Kelly Marie Tran of “Star Wars: The Rise of Skywalker” lent her voice to this project.

Europe from Space Got three minutes to spare for a tour of southern Europe? That’s all the time it takes, when you have a 4K camera orbiting Earth 250 miles up—and we do, on the International Space Station. This Ultra High Definition video was shot in August 2016 as the station traveled nearly 1000 miles, taking in views from above the western coast of France to the Iberian Peninsula, Italy, Switzerland, southern Germany and Austria, and southward to the countries of the Balkan Peninsula.
