SpaceX launched two NASA astronauts toward the International Space Station on May 30.

It marked the first time in history that a commercial aerospace company carried humans into Earth's orbit.

NASA and space fans waited nearly a decade for this milestone. The United States hadn't launched its own astronauts into space since the shuttle program ended in 2011.

The astronauts successfully returned to Earth on Sunday, August 2.

In a statement on August 2, the Coast Guard said, "With limited assets available and with no formal authority to establish zones that would stop boaters from entering the area, numerous boaters ignored the Coast Guard crews' requests and decided to encroach the area, putting themselves and those involved in the operation in potential danger."
