The High Resolution Dynamics Limb Sounder (HIRDLS) instrument onboard the NASA Aura spacecraft experienced a rupture of the
thermal blanketing material (Kapton) during the rapid depressurization of launch. The Kapton draped over the HIRDLS scan
mirror, severely limiting the aperture through which HIRDLS views space and Earth's atmospheric limb. In
order for HIRDLS to achieve its intended measurement goals, rapid characterization of the anomaly, and rapid recovery from it
were required. The recovery centered around a new processing module inserted into the standard HIRDLS processing scheme,
with a goal of minimizing the effect of the anomaly on the already existing processing modules.
We describe the software infrastructure on which the new processing module was built, and how that infrastructure allows for
rapid application development and processing response. The scope of the infrastructure spans three distinct anomaly recovery
steps and the means for their intercommunication. Each of the three recovery steps (removing the Kapton-induced oscillation
in the radiometric signal, removing the Kapton signal contamination upon the radiometric signal, and correcting for the
partially-obscured atmospheric view) is completely modularized and insulated from the other steps, allowing focused and rapid
application development towards a specific step, and neutralizing unintended inter-step influences, thus greatly shortening
the design-development-test lifecycle. The intercommunication is also completely modularized and has a simple interface to
which the three recovery steps adhere, allowing easy modification and replacement of specific recovery scenarios, thereby
heightening the processing response.
