    This is the best summary I could come up with:


    Yesterday, a NASA livestream falsely indicated that an ISS astronaut was experiencing decompression sickness (DCS), a potentially life-threatening condition, ahead of a scheduled spacewalk.

    NASA broadcast an emergency situation on board the ISS on Wednesday at 6:32 p.m., with a voice from ground control asking to put an unnamed “commander” in his spacesuit for hypobaric treatment after being exposed to increased pressure.

    About an hour later, the space agency clarified that there was no emergency situation on the ISS; instead the aired audio was from a simulation channel on the ground “indicating a crew member was experiencing effects related to decompression sickness,” NASA wrote on X.

    “This audio was inadvertently misrouted from an ongoing simulation where crew members and ground teams train for various scenarios in space and is not related to a real emergency,” NASA added.

    Decompression sickness, also known as the bends, typically occurs with change in pressure during scuba diving and can sometimes affect astronauts during spacewalks, forming bubbles in the bloodstream.

    NASA had scheduled a spacewalk on Thursday for astronauts Tracy Dyson and Matt Dominick to complete the removal of a faulty electronics box.
