You know me and my tweaks haha. I like where you are going with this, might I suggest…

Seeking to defuse this
emerging threat, daring
Senators have secretly
commissioned the pilots
of a brave RESISTANCE
to find the last Jedi and
restore the light of hope
to the darkening stars…

The reason for the tweak…

Make it sound more present tense
Make it so the leaders do not seem afraid and are actually competent
Make it so that it is not the Senate but only a select few that are supporting the Resistance in hopes to de-escalate the conflict.
