Destiny 2's new event, Faction Rallies, kicked off this week and runs until the weekly reset on October 3. Now, Bungie has come forward to say Faction Rallies are not necessarily going to be a weekly event (not that the studio ever said they would be).

In its latest weekly blog post, Bungie said Faction Rallies is a "new ritual" for Destiny 2 that will come to the Tower only "periodically." After this first Faction Rallies event ends next week, it might be a little while before the next one takes place. All Bungie said is that Faction Rallies will return in the "near future."
