Bernhard Christ, an amateur astronomer from Germany, put himself in just the right spot on the Earth’s surface (a testament to his mad plottin’ and plannin’ skillz) and using a digital astronomical camera produced this sequence – made in less than 0.4 seconds – of the International Space Station transiting across the Moon…

That’s five shots of the ISS taken at equal intervals. If you’re wondering where the fifth is, click on the image to drastically embiggen it and look just inside the Moon’s limb toward the left side of the picture and you’ll easily pick it out from the lunar landscape.

Aim here for more about Bernhard Christ’s astonishing photo, and many thanks to Shane Thacker for the great find!...

The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor collected. The rest of contaminants – the yucky brine in the urine – is thrown away, said Marybeth Edeen, the space station’s national lab manager who was in charge of the system.

The water vapor is mixed with water from air condensation, then it goes through filters, much like those put on home taps, Edeen said.

When six crew members are aboard it can make about six gallons from urine in about six hours, Edeen
