(Wright) Now what I have here
is called an EVA wipe. EVA stands
for extravehicular activity. Let
me open this up. EVA is when an
astronaut will go out and do a
spacewalk. In this particular
case, an astronaut used this while
we were investigating the SARJ,
the solar alpha rotary joint. The
astronaut went out there, and
they used this for a cleaning
procedure -- put it over their
glove, they're out in space -- and
you can see there's dark on this
glove. They used this to clean
out that joint because there was
all that debris that had
accumulated over time. And they
had to make sure that it was
clean enough so that we can keep
on using it. And this is what
they used. If you were able to
look at this up close, it looks
almost like a bath towel. It's
terry. We use a lot of those kinds
of different types of materials
when we are dealing with space.
And that was able to grab some of
that debris. They also used some
grease, added the grease and cleaned
up, and that's how they were able
to remove a lot of that debris.
