Called the Aquarius Reef Base,the school-bus-size habitat is anchored on the seafloor 19 meters underwater and 10 kilometers off the coast of Florida. “We’re not really deprived of much,”said Jeanette Epps.For their nine-day mission,the crewmembers were allowed to bring iPads,iPhones,and a few sets of clothes.“We have lots of windows and we got great views out here with fish,”astronaut Mark Vande Hei said.“I am certain that none of us have felt fear.” Japanese astronaut Akihiko Hoshide said their living quarters feel similar in size to one or two modules on board the International Space Station.It helps that their hygiene is good,and they have a real shower — a luxury compared with the no-rinse shampoo and washcloths that astronauts use in space.Though Vande Hei admitted,“We’re probably less sensitive to smell as we stay down here longer and longer.” The astronauts have been performing several extravehicular activities,which are really just simulated underwater spacewalks.During those ventures outside the habitat,mission controllers often introduce a 10-minute time delay in their communications to mimic the lag astronauts visiting a far-flung space body,such as Mars,would experience when talking to mission managers on the ground.“We have to take this time delay into account in the operations concept and even the design of those spacewalks,”said Thomas Pesquet. |
