Starliner Spacecraft’s Speaker Produced Uncommon Sonar Sounds on Saturday
### A Space Enigma: Unexplained Sounds Emerge from Boeing’s Starliner Docked at the ISS
On an ostensibly ordinary Saturday aboard the International Space Station (ISS), NASA astronaut Butch Wilmore stumbled upon an unforeseen auditory phenomenon within Boeing’s Starliner spacecraft. The vehicle, which has been moored at the ISS for almost three months, produced a peculiar sound that Wilmore characterized as a “pulsing noise, akin to a sonar ping.”
### The Event
The situation arose when Wilmore detected the atypical sound emanating from a speaker within the Starliner. He quickly communicated with Mission Control at NASA’s Johnson Space Center in Houston to report the anomaly. “I’ve got a question about Starliner,” Wilmore stated. “There’s an unusual noise coming through the speaker … I’m uncertain of its origin.”
Wilmore conjectured that the sound could be related to some anomaly in the connection between the ISS and the spacecraft. He asked the flight controllers in Houston to listen to the audio from Starliner to assist in diagnosing the matter. Mission Control rapidly established a “hardline” connection to monitor the audio feed from the spacecraft.
As Wilmore positioned his microphone near the speaker, the notable sonar-like ping was recorded and sent back to Earth. “Alright Butch, that one came through,” Mission Control affirmed. “It was somewhat like a pulsing noise, resembling a sonar ping.”
Wilmore reiterated the procedure, allowing the flight controllers to hear the noise again before leaving the investigation in their hands. “Alright, over to you. Contact us if you find out what’s going on,” he noted.
### A Space Enigma
The odd sound was documented and shared by Rob Dale, a meteorologist from Michigan, who uploaded it online. The recording has since ignited curiosity and theories, as the origin of the sound remains unknown.
In space, astronauts sometimes experience bizarre phenomena that are hard to explain. For example, during China’s inaugural human spaceflight in 2003, astronaut Yang Liwei reported a noise reminiscent of an iron bucket being struck by a wooden mallet while in orbit. Scientists later linked this noise to minor deformations in the spacecraft resulting from pressure differentials between its inner and outer walls.
While the sonar-like sound in Starliner is likely to have a harmless explanation, it is significant given the string of difficulties Boeing and NASA have encountered with the spacecraft. These challenges encompass substantial helium leaks during flight and malfunctioning thrusters, which have sparked concerns regarding the spacecraft’s dependability.
### The Path Forward for Starliner
Despite these concerns, NASA and Boeing are advancing with plans to return Starliner to Earth. Initially, the spacecraft was intended to bring back its crew, including Wilmore and fellow astronaut Suni Williams. However, due to the ongoing uncertainties surrounding Starliner’s functionality, NASA opted to bring the spacecraft home autonomously.
Starliner is now set to return to Earth on Friday, September 6, 2024. Meanwhile, Wilmore and Williams are projected to come back to Earth in February 2025 aboard a Crew Dragon spacecraft, which is slated for launch with just two astronauts later this month.
### Conclusion
The enigmatic noise within Starliner adds yet another layer of fascination to the ongoing tale of Boeing’s beleaguered spacecraft. While the sound is likely inconsequential, it serves as a reminder of the intricacies and unpredictabilities in space exploration. As Starliner gears up for its autonomous return to Earth, all eyes will be on Boeing and NASA to observe how they tackle the challenges ahead and ensure the spacecraft’s safe return.
