Spacewalkers to Make Critical Space Station Repairs

Houston - Two astronauts are set to step outside the International Space Station (ISS) today and make a critical repair to aid future construction of the orbital laboratory.

Spacewalkers Piers Sellers and Michael Fossum, who spent more than seven hours working outside the ISS Saturday, will once again don their U.S.-built spacesuits to restore the station’s mobile crane to full operations. The spacewalk was set to begin at 8:13 a.m. EDT (1213 GMT).

The primary task for Sellers and Fossum, both mission specialists for NASA’s STS-121 shuttle mission aboard Discovery, is to replace a reel-like power and data cable system that was severed late last year due to a still-unexplained glitch.

Known as a Trailing Umbilical System (TUS) Reel Assembly, the system transfers electricity, data and video to the space station’s railcar-like Mobile Transporter. The transporter itself is a critical movable platform for shifting the ISS robotic arm or massive station components along the orbital laboratory’s main truss.

“It’s mobile now, but it’s only dependable on one string,” Sellers told reporters Sunday during a space-to-ground video link. “And when we’re done tomorrow, it will have two strings and therefore be more reliable.”

A "must read" Open File Report that is a comprehensive account of the USGS participation in the Apollo era, from its conception through the end of Project Apollo, has been completed by Gerald G. “Jerry” Schaber during the time he was with the U.S. Geological Survey, Branch of Astrogeology, working as a Scientist Emeritus. We talk with the man behind the book, who filled that significant gap of history with regard to the participation of the USGS.

Every story has a heart and a soul, and Jerry hands these rich gifts to the reader with respect and perspective. Now Jerry shares with us, the thinking behind the book.

Q. Tell us, how does it feel to have completed the open file report?

A. Well, it feels very good as you might expect. It was a long time in coming.

Q. How long did it take?

A. I started in 2000, encouraged by Wes Ward, Carolyn Shoemaker and other people at the time to do it. I finished in 2002, but it was in editing ever since.
