Or is that "Go deep?"

CAPE CANAVERAL, Fla. - The astronaut chosen to make emergency repairs
on the space station's ripped solar wing - a dangerous and
unprecedented electrical job - is actually an emergency medical doctor
and mountaineer whose specialty at NASA just happens to be spacewalks.

What's more, Scott Parazynski is 6-foot-2 (188 centimeters tall) and
has long arms, a lucky stroke since he'll be working Saturday
alongside a damaged electrical generator with hot wires possibly
exposed.

"We have a bunch of challenges ... but the beauty of having Scott
available to us is that it's one piece that you don't worry about,"
flight director Derek Hassmann said Friday. "I cannot overstate the
significance of his experience and just his approach to the job."

To save the solar wing, Parazynski needs to clear whatever snagged the
panels and caused the wing to tear while it was being unfurled
Tuesday. He won't know what he's up against until he sees the damage
up close.

As it is now, the wing poses a structural hazard for the international
space station. The damage could worsen and the wing could become
unstable, quite possibly forcing NASA to cut it loose and lose a vital
power source for future laboratories.

That's why NASA is willing to undertake this riskier and trickier than
usual spacewalk before the shuttle Discovery undocks from the space
station in just another few days. The shuttle is currently due to
undock on Monday and return to Earth on Wednesday.

Complicating matters for NASA is a malfunctioning solar rotary joint
on the opposite side of the space station. It's needed to turn another
set of solar wings toward the sun, but it's gummed up with steel
shavings and, for the most part, unusable.

For now, the torn wing is the priority. Because of the tight schedule,
the work on the joint has been put off for another time. Also put off
was a demonstration of a high-tech caulking gun and goo for mending
shuttle thermal tiles, a technique that Parazynski helped develop.
