Apologies for the tardy Tuesday morning post, folks. It was an early and a very busy travel day yesterday and I confess----I fell asleep early last night & didn't post. Mea culpa. But I hope these photos I took while visiting daughter Serena (who's doctor of Internal Medicine and a NASA astronaut).
She invited several of her close friends on Thanksgiving week to bring their kids and watch one of her regular EVA "training sessions" in the Neutral Buoyancy Training pool at NASA in Johnson Space Center in Texas.
Photos of pool and Serena suited up for the dive. Same type of suit that's used in space for EVA.
She and another astronaut go down deep enough to reach the atmospheric pressure that mimics weightlessness in space. EVA (Extracurricular Vehicle Activity) occurs in space when the astronauts have to go outside of the International Space Station to do repair work or to haul in
cargo brought up on cargo flights, like the ones delivered by SpaceX Dragon rockets lately.
Each astronaut has two experienced divers floating near them while the perform various tasks on the underwater replicas of the Space Station. Also they lower them into pool with that lift device. It's totally
fascinating to watch. We even got to go up into the Control Room with the scientists and engineers watch large screens to guide their various activities.
