During the DEMO-2 live stream there was a black section visible above the heads of the astronauts. In an image tweeted out by Elon these were labeled as “9” and “10” with symbols of water droplets.
What is inside these compartments? My first assumption was, that it was a toilet, although this source claims there is none. Is it cargo for the ISS? If so why do the compartments require the symbol? Is it drinking water for the flight? Why is it so much? The astronauts are expected to be alone in the capsule for less then a day during their entire trip. Is it maintenance access to the life support system?
