This manifests principally as a change in the plate scale and secondarily as a change in the geometric distortions. These effects are well modeled by adjustments to the rhoA and kA parameters which are used to transform the star selector servo angles into FGS (x, y) detector space coordinates. By observing the relative positions of selected stars in a standard cluster at a fixed telescope pointing and orientation, the evolution of rhoA and kA can be monitored and calibrated to preserve the astrometric performance of FGS1r.

NICMOS Imaging of Protostars in the Orion A Cloud: The Role of Environment in Star Formation
We propose NICMOS observations of a sample of 252 protostars identified in the Orion A cloud with the Spitzer Space Telescope. These observations will image the scattered light escaping the protostellar envelopes, providing information on the shapes of outflow cavities, the inclinations of the protostars, and the overall morphologies of the envelopes

(NASA) - When astronauts return to Hubble for Servicing Mission 4 this fall, they will be revamping and reenergizing the telescope for the final leg of its journey. One of the tasks they aim to complete is the installation of New Outer Blanket Layers, or NOBLs.
Since its deployment, Hubbles thermal blankets have taken the brunt of the harsh space environment
