Default Zvezda MMOD Shields

A ways back, Zvezda was to get a pair of "wings" attached to either
side of the module to improve protection from MMOD hits. Have they
been canceled or are they going to be brought up on one of the
remaining two shuttle flights?

The Service Module Debris Panels (SMDP) have already been installed. I
recall seeing an illustration a number of years ago depicting them as a pair
of wings (as you say), but that design obviously was changed.

The first set of panels was delivered to ISS during
STS-111/Endeavour/ISS-14-UF2 in June 2002. They were stowed temporarily on
PMA-1 during EVA 1 by Chang-Diaz and Perrin. These six panels were retrieved
from PMA-1 and installed on the conical hull section of Zvezda by the ISS
Exp-5 crew during Russian EVA 7 on 16 Aug 2002 (Korzun and Whitson).

The rest of the panels were delivered on STS-116/Discovery/ISS-20-12A.1 in
Dec 2006 and stowed on PMA-3 during EVA 3 (Curbeam and Williams). They were
retrieved from PMA-3 and stowed on Zvezda by the ISS Exp-15 crew during
Russian EVA 18 on 30 May 2007 (Yurchikhin and Kotov). Five of the panels
were also installed on the conical hull section during that EVA. The final
twelve panels were installed by the same EVA crew during the next Russian
EVA on 6 Jun 2007.
