Yesterday's coffee into today's coffee - Astronauts busy collecting recycled urine samples
With just two more days together, the astronauts of the linked space shuttle and space station busily collected as many recycled urine samples as possible from a machine that they coaxed into operation.
The device for turning urine into drinking water - a critical part of the space station's new water recycling system - seemed to be working fine Tuesday after several days of tinkering by the astronauts. They laughed and described the process as turning "yesterday's coffee into today's coffee," and labeled a few bags as such.
