NASA had to reassure the public that there was no emergency on the International Space Station after audio from a medical training drill was mistakenly played during a livestream on Wednesday night.

The regularly scheduled livestream was interrupted at 6:28pm ET by an unidentified speaker, apparently a flight surgeon, communicating with the ISS crew about what to do for the commander, who was suffering from severe pressure illness.

The speaker advised crew members to “check the pulse again” before placing the injured astronaut in a spacesuit filled with pure oxygen. She said any treatment was “the best treatment” and better than nothing.

“Unfortunately, Commander's prognosis is relatively uncertain,” she said.

“I'm concerned that there are people with severe DCS,” she said. [decompression sickness] He “hits” and tells the crew to get him suited up as quickly as possible.

She mentions that there is a hospital in San Fernando, Spain, with a hyperbaric treatment facility, apparently implying that she would order an emergency evacuation of the space station.

But after stirring up fear among space enthusiasts listening in, NASA revealed that this scenario wasn't real: All crew members aboard the ISS were safely asleep at the time.

NASA said there was “no emergency on board the International Space Station.”

“At approximately 5:28 p.m. CDT, audio was broadcast on NASA's livestream from a ground-based simulated audio channel indicating the crew member was experiencing symptoms associated with decompression sickness,” NASA said in a statement. X's message.

“The audio was inadvertently transmitted from an ongoing simulation in which crew and ground teams were training for various scenarios in space and is not related to an actual emergency,” NASA said in a statement.

“The International Space Station crew was asleep at the time. All crew members are healthy and safe, and tomorrow's spacewalk will begin as scheduled at 8 a.m. EDT,” it added.

The emergency training came after two astronauts aboard Boeing's Starliner spacecraft successfully docked with the ISS last week.
