The required pointing correction exceeds the limit allowed by the appropriate target acquisition Procedure. The uplink window closes before the SIP can be issued. It is better to be safe than sorry. The science may be of little or no utility, but no harm should result to the spacecraft or science instrument. Thus it is always better to abort a Mode I TA than to uplink a dubious pointing correction.
Bad science is worse than no science.
An aborted Mode I TA must be reported to the General Observer and documented in the RTI table, and later in the PDQ file. It should also be reported in the shift report. Even if your command is uplinked and executed, it is essential that you document anything about the target acquisition that appeared anomalous or doubtful. If the command was not verified, the TA must be regarded as failed. In some cases the condition that resulted in the inability to complete the target acquisition is temporary.
