While patrolling Federation space, the USS Shenzhou encounters an object of unknown origin, putting First Officer Michael Burnham to her greatest test yet.


Log entries[]

First officer's log, stardate 1207.3 
On Earth, it's May 11, 2256, a Sunday. The crew of the USS Shenzhou has been called to the edge of Federation space to investigate damage done to one of our interstellar relays. Blast burns around the hole are inconclusive. Were they caused by an asteroid, or was it deliberately destroyed to limit Starfleet communications? And if so, by whom? Despite the risks of our mission, I remain optimistic. It's hard not to be in the face of such beauty–in this case, a binary star system. Around these two suns, ice, dust, and gasses collide to form planets future generations will call home. A humbling reminder that all life is born from chaos and destruction.
