CAPE CANAVERAL, Fla. – In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians install multi-layer insulation on the Meteoroids and Debris Protective Shield of the Permanent Multipurpose Module, or PMM. The reflective silver mesh is Mylar, which is aluminized to protect hardware aboard the International Space Station from solar thermal radiation. The Leonardo multi-purpose logistics module, or MPLM, is being modified to become the PMM that will carry supplies and critical spare parts to the station aboard space shuttle Discovery’s STS-133 mission. Discovery, targeted to launch Nov. 1, will leave the module behind so it can be used for microgravity experiments in fluid physics, materials science, biology and biotechnology.
