Figured it out~! Odyssey Missions start to show only if you start playing Odyssey through clicking the "BLAST OFF" button in the mission tab. That is, the lower right hand place where missions show up. However, i wasn't able to get this to show up UNTIL i clicked BLASTOFF from the left hand side where it explains everything about the new event.

So basically, to get missions and stuff to show up, blast off once (from left hand side) and play game to get the blast off available in missions. Click Blast off in the missions tab---missions appear.

You will not get missions or any augment slots if you simply choose the Extraction game type from the Play Game tab without clicking any of the BLAST OFF buttons.
