Holes in the ISS Cupola

Destin of Smarter Every Day visits the engineering genius who designed the outer window shades of the ISS’s cupola, which are mechanically opened from the inside, while still maintaining a pressure seal.

NASA astronauts explored the phenomenon of water surface tension in microgravity on the International Space Station by floating a GoPro camera inside a free-floating bubble of water the size of a softball. The astronauts also filmed the event with the 3D camera on board the ISS, and uploaded the 3D version as a separate video.

World’s Largest Vacuum Chamber

On BBC‘s “Human Universe,” host Brian Cox visits NASA’s Space Power Facility in Ohio to see what happens when a bowling ball and a feather are dropped together under the conditions of outer space.

Mars Flyover

This ‘flyover’ comes courtesy of Mars Express which was launched by the European Space Agency on 2 June 2003 and arrived at Mars six and a half months later. The spacecraft has orbited the Red Planet nearly 12,500 times since its arrival and has beamed back data and images collected by the scientific instruments aboard.

This data was collated to create a nearly global digital topographic model of Mars’ surface, making the viewing of the ‘flyover’ a three dimensional experience. The images were taken by the High Resolution Stereo Camera (HRSC) run by the DLR German Aerospace Center; the flyover explores the grabens, valleys, canyons, mountains and lava flows in unprecedented detail. These 3D images aid researchers in understanding the climate and development of Mars.

Canadian Space Agency astronaut Chris Hadfield performed a simple science experiment designed by grade 10 Lockview High School students Kendra Lemke and Meredith Faulkner. The students from Fall River, Nova Scotia won a national science contest held by the Canadian Space Agency with their experiment on surface tension in space using a wet washcloth. The results are surprising.
