Space Shuttle Processing Status 22 Jul 2002

Shuttle Status: Shuttle Status: Due to the inspections and subsequent
engineering investigation of the Main Propulsion System (MPS) liquid
hydrogen and liquid oxygen flow liner on all four Space Shuttle orbiters,
mission managers have changed all launch dates to under review. (The soonest
any Shuttle could be ready for launch is currently estimated to be Sept. 26,
2002.) Meanwhile, a full engineering review is being conducted by NASA to
determine the cause of the cracks found on the orbiter’s flow liners and to
develop an appropriate remedy. Various engineering teams across the country
continue to analyze data to determine the appropriate course of action that
will lead to the resumption of safe launches.

A decision is expected by the end of the week to select the best repair
options. A decision is expected by the end of the month to proceed with the
repairs or to fly as is.

The orbiters are currently being processed for their future flights up to
the point of engine installation.
