- I don't think that would be a wise thing to do. The motor firing has be
- done at a precise time with the spacecraft in the proper attitude. If the
- hammering was done during the motor firing, and the antenna was to pop
- open, it could change the spacecraft attitude enough to really mess up the
- orbit insertion. Besides, the spacecraft will very busy as it is during
- the orbit insertion, collecting the probe data, performing a 1000 km Io flyby
- and collecting science data on Jupiter.
