I was visiting Earth on a patrol, now that I'm level 20, to visit places that I couldn't get to before. I heard this area (near the rail yards where the fallen and hive are duking it out, there's a building guarded by some fallen vandal elites or a servitor. Go all the way into the building and you will be blocked by glass doors.) opens up after reaching lvl 20, but the doors are still closed and can't be opened. Does anyone have more details about how to get in? Do you think this area will be intentionally blocked off for an earth based raid to be released in the future?
