New Outer Blanket Layer (NOBL) Installation EVA Animation
Released on August 22, 2008
A NOBL consists of stainless steel panels covered with a protective Multi-Layer Insulation (MLI) thermal coating. These panels fit over existing, degraded insulation on Hubble's exterior surface, to control Hubble's internal temperature. The NOBL will be permanently mounted.
Wide-Field Planetary Camera 2 (WFPC2) was installed in Dec 1993 and used to obtain high resolution images of astronomical objects. This camera was removed in the last servicing mission so it is no longer in service.
