Early Thursday morning, residents across California were startled by a loud sonic boom that reverberated through the state. Many initially mistook the powerful sound for an earthquake. The source of the disturbance was quickly identified as the reentry of NASA’s Crew-11 capsule, a SpaceX Dragon spacecraft returning from the International Space Station (ISS). The mission, which concluded earlier than planned, was prompted by a medical concern involving one of the astronauts, though authorities assured the public that the situation was not critical.
