One more week

isn’t Monday the 18th?

Yes, the linked space.com article has an error. The launch is happening Tuesday the 19th.

I prefer to call it an unplanned calendar learning opportunity.

If they'd just left it in UTC there wouldn't have been an error and the 'rest of World' could easily calculate in their local timezone.
