Astronauts' spacewalk repair fails
Astronauts from the space shuttle Discovery have failed to repair an
improperly installed cargo platform on the international space station
during their third and final spacewalk.
Joseph Acaba and Richard Arnold were trying to free the cargo platform which
jammed after a locking pin had been installed upside down on an earlier
spacewalk.

Eliminating Waste
Each spacewalking astronaut wears a large, absorbent diaper called a Maximum
Absorption Garment (MAG) to collect urine and feces while in the space suit
. The astronaut disposes the MAG when the spacewalk is over and he/she gets
dressed in regular work clothes. |

third manned space mission.
A 42-year-old fighter pilot, Zhai Zhigang, has been chosen to perform the

State-run news agency Xinhua said the "yuhanguan" (astronauts) were making
final preparations for the lift-off.
The spacewalk is scheduled to be broadcast liv |

China is gearing up for its third manned spaceflight, set to include its
first ever spacewalk, later this month.
The three-member crew is not yet named for the Shenzhou 7 mission, due to
launch sometime between Sept. 25 and Sept. 30 from Jiuquan Satellite Launch
Center in Gansu Province, China, but a spokesman for the launch center told
the Shanghai Daily newspaper that preparations were on track for liftoff.
