From a launch pad at the Kennedy Space Center on Sunday, Elon Musk's SpaceX launched its latest rocket test into the Florida sky. Less than two minutes later, it exploded — just like the company hoped it would.

Anti-government protests in Hong Kong continued on Sunday as tens of thousands of demonstrators took to the streets to defy the ban on face masks that went into effect just days earlier.

Hong Kong's chief executive Carrie Lam announced Friday that she would use colonial-era emergency powers to enforce the ban that targets those wearing face masks at public gatherings. Lam is the first to invoke those powers in more than 50 years.

The U.S. citizenship oath consists of 140 words. Some of those are more contemporary, others more archaic. That's because the idea of the citizenship oath is almost as old as the Constitution itself.
