NEW YORK, June 13: NASA has reassured the public that there is no cause for alarm aboard the International Space Station (ISS) following an incident during an official live stream. The space agency was compelled to issue the denial after a medical drill simulation, mistakenly broadcasted on the stream, sparked concerns on social media.

In a statement posted on the NASA ISS Twitter account, officials clarified, "There is no emergency situation going on aboard the International Space Station. The audio was inadvertently misrouted from an ongoing simulation where crew members and ground teams train for various scenarios in space."

The incident occurred on Wednesday at 5:30 PM CDT (10:30 PM GMT) when viewers noticed a sudden interruption in the NASA ISS live stream. Instead of the usual footage, a message appeared, indicating a temporary interruption due to connection issues.

During the interruption, a voice resembling a communication link with the ISS crew relayed instructions related to a simulated emergency involving a "commander" experiencing decompression sickness. The speaker, identified as a flight surgeon at SpaceX mission control center in Hawthorne, California, issued directives aimed at addressing the medical situation.

Flight surgeons, NASA explained, are physicians with specialized training in aerospace medicine stationed at mission control centers. Despite the realistic nature of the simulation, viewers expressed concern as the situation seemed to escalate, with the "commander's" condition appearing to worsen.

Social media platforms buzzed with discussions about the incident, with some users finding it unsettling. Eric Berger, the space editor at Ars Technica, described the broadcast as "frankly scary," though many recognized it as likely a drill.

SpaceX later clarified that the audio heard during the stream was part of a test conducted in California and assured that all training crew members were "safe and healthy."

NASA emphasized that the simulation was unrelated to any actual emergency and that the ISS crew was in their scheduled "sleep period" when the drill inadvertently aired. "All remain healthy and safe, and tomorrow's spacewalk will start at 8 AM EDT as planned," NASA stated in its release.
