Haven't they seen "Prometheus" in the future? You just simply don't touch things you find on mysterious planets that were home to ancient, inscrutable beings and you certainly don't bring them onto your ship. That's how you get tentacle babies.
Here's the official synopsis from 343 Industries and Haloy Waypoint:
This week on Halo 4: Spartan Ops -- The mysterious artifact recovered from Requiem takes control of vital systems on board the UNSC Infinity, forcing the Spartans of Crimson and Majestic back down to the planet to look for a way to free the ship. Commander Lasky and the UNSC need you, Spartan...get back in the game!
The second episode makes its debut on Monday, November 11th.
