NASA's Artemis II astronauts underwent suit leak checks before historic launch

In the final hours before liftoff, Artemis II astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen put their suits through critical leak checks to make sure everything is in place before heading into space. These suits will protect the astronauts and keep them pressurized. Sometimes, the astronauts have to hold their breath for about 10 seconds because movement in the suit could cause changes in the pressure.
