NASA GIVES SPACE STATION CREW 'GO' TO DRINK RECYCLED WATER
HOUSTON -- NASA's Mission Control gave the Expedition 19 astronaut
crew aboard the International Space Station a "go" to drink water
that the station's new recycling system has purified.
This is an important milestone in the development of the space
station," said Kirk Shireman, International Space Station deputy
program manager at NASA's Johnson Space Center in Houston. "This
system will reduce the amount of water we must launch to the station
once the shuttle retires and also test out a key technology required
for sending humans on long duration missions to the moon and Mars."
