This puzzle requires the “Just Beam it into Space” spec record, Mariner’s combadge and the three square combadge components.
With the internal components placed, and the combadge assembled, there are six letters visible through the holes on the front and back of the combadge. The “Just Beam it into Space” spec record can help guide you on how the internal components should be arranged.
When the internal components are placed correctly, the carved channel inside the combadge will be passing through some letters, in order, that spell out a word.
With the internal components placed correctly, the reassembled badge will show six key letters that will spell the answer.
You’ll need to arrange the internal components so that the carved channel passes through letters that spell out SHIELD.
ANSWER REVEAL: With the internal components placed correctly, the assembled badge will show the letters A, C, T, on one side, and the letters I, V, E, on the other. The spells out ACTIVE. Looking at the combadge “delta” envelope, active is synonymous with OPERATIONAL. So OPERATIONAL is the keyword that grants access to the envelope.
