A sonic boom is expected to echo across the night sky on Tuesday at approximately 2:31 a.m. PT as a SpaceX Dragon spacecraft prepares to splash down off the coast of San Diego, California. The spacecraft, returning from a mission to the International Space Station (ISS), is set to land in the Pacific Ocean after successfully undocking earlier this week.
At 7:15 a.m. on Monday, the spacecraft undocked from the ISS, marking the beginning of its return journey. The SpaceX Dragon is carrying four astronauts from the Ax-4 mission: Peggy Whitson, Shubhandshu Shukla, Sławosz Uznański-Wiśniewski, and Tibor Kapu. The crew has been conducting scientific experiments and activities aboard the ISS since their launch on June 25, 2025, from Kennedy Space Center in Florida.
SpaceX has confirmed that the Dragon spacecraft will execute a series of orbit-lowering maneuvers as it prepares for reentry into Earth’s atmosphere. These maneuvers will include the jettisoning of its trunk, which is a component designed to carry cargo during the mission. After approximately 22.5 hours of transit, the spacecraft is anticipated to make a safe and controlled splashdown in the ocean.
As part of the return process, SpaceX has been providing real-time updates via its X account, formerly known as Twitter, to inform the public and space enthusiasts about the ongoing mission and the wellbeing of the Ax-4 crew. They have reported that the Dragon and its astronauts are currently on course for a safe reentry.
Impact on Local Area
Local residents should be aware of the potential disturbance caused by the sonic boom during the splashdown. As the spacecraft re-enters the atmosphere, it will exceed the speed of sound, creating a sonic boom that can be heard over a wide area. This event is not only significant for those directly involved with the mission but also for the local community, which will experience the unique sound associated with space exploration.
History of the Mission
The Ax-4 mission is part of a series of ongoing collaborations between SpaceX and NASA, focusing on crewed flights to the ISS. The four astronauts have engaged in various scientific research projects, contributing to advancements in human spaceflight and understanding of life in microgravity. Their successful return will further highlight the capabilities of private spaceflight enterprises and their contributions to international space exploration efforts.
SpaceX aims to enhance public engagement and interest in space activities by streaming the splashdown live on its X account. This initiative allows fans and followers to witness the final moments of the Dragon spacecraft’s mission and reaffirm SpaceX’s commitment to transparency and accessibility in space exploration.
As the Ax-4 crew approaches their homecoming, their journey underscores the vital role of space missions in fostering scientific knowledge and international collaboration in the pursuit of understanding our universe. The anticipated splashdown will not only mark the conclusion of their expedition but also serve as a milestone in the continuing advancements of commercial space travel.
