〃She seems to know what shes doing;〃 Ted said; approvingly。
〃She does;〃 Barnes said。 〃But all the major support systems are redundant。 Fletcher is just our final redundancy。 Actually; youll find the entire habitat is self…regulating。〃
He clipped heavy badges onto the jumpsuits。 〃Wear these at all times; even though theyre just a precaution: the alarms trigger automatically if life…support conditions go below optimum。 But that wont happen。 There are sensors in each room of the habitat。 Youll get used to the fact that the environment continually adjusts to your presence。 Lights will go on and off; heat lamps will turn on and off; and air vents will hiss to keep track of things。 Its all automatic; dont sweat it。 ''57'' Every single major system is redundant。 We can lose power; we can lose air; we can lose water entirely; and we will be fine for a hundred and thirty hours。〃
One hundred and thirty hours didnt sound very long to Norman。 He did the calculation in his head: five days。 Five days didnt seem very long; either。
They went into the next cylinder; the lights clicking on as they entered。 Cylinder C contained living quarters: bunks; toilets; showers (〃plenty of hot water; youll find〃)。 Barnes showed them around proudly; as if it were a hotel。
The living quarters were heavily insulated: carpeted deck; walls and ceilings all covered in soft padded foam; which made the interior appear like an overstuffed couch。 But; despite the bright colors and the evident care in decoration; Norman still found it cramped and dreary。 The portholes were tiny; and they revealed only the blackness of the ocean outside。 And wherever the padding ended; he saw heavy bolts and heavy steel plating; a reminder of where they really were。 He felt as if he were inside a large iron lung…and; he thought; that isnt so far wrong。
They ducked through narrow bulkheads into D Cyl: a small laboratory with benches and microscopes on the top level; a pact electronics unit on the level below。
〃This is Tina Chan;〃 Barnes said; introducing a very still woman。 They all shook hands。 Norman thought that Tina Chan was almost unnaturally calm; until he realized she was one of those people who almost never blinked their eyes。
〃Be nice to Tina;〃 Barnes was saying。 〃Shes our only link to the outside…she runs the ops; and the sensor systems as well。 In fact; all the electronics。〃
Tina Chan was surrounded by the bulkiest monitors Norman had ever seen。 They looked like TV sets from the 1950s。 Barnes explained that certain equipment didnt do well in the helium atmosphere; including TV tubes。 In the early days of undersea habitats; the tubes had to be replaced daily。 Now they were elaborately coated and shielded; hence their bulk。
Next to Chan was another woman; Jane Edmunds; whom Barnes introduced as the unit archivist。
〃Whats a unit archivist?〃 Ted asked her。
''58'' 〃Petty Officer First Class; Data Processing; sir;〃 she said formally。 Jane Edmunds wore spectacles and stood stiffly。 She reminded Norman of a librarian。
〃Data Processing 。。。〃 Ted said。
〃My mission is to keep all the digital recordings; visual materials; and videotapes; sir。 Every aspect of this historic moment is being recorded; and I keep everything neatly filed。〃 Norman thought: She is a librarian。
〃Oh; excellent;〃 Ted said。 〃Im glad to hear it。 Film or tape?〃
〃Tape; sir。〃
〃I know my way around a video camera;〃 Ted said; with a smile。 〃Whatre you putting it down on; half…inch or threequarter?〃
〃Sir; we use a datascan image equivalent of two thousand pixels per side…biased frame; each pixel carrying a twelvetone gray scale。〃
〃Oh;〃 Ted said。
〃Its a bit better than mercial systems you may be familiar with; sir。〃
〃I see;〃 Ted said。 But he recovered smoothly; and chatted with Edmunds for a while about technical matters。
〃Ted seems awfully interested in how were going to record this;〃 Barnes said; looking uneasy。
〃Yes; he seems to be。〃 Norman wondered why that troubled Barnes。 Was Barnes worried about the visual record? Or did he think Ted would try to hog the show? Would Ted try to hog the show? Did Barnes have any worries about having this appear to be a civilian operation?
〃No; the exterior lights are a hundred…fifty…watt quartz halogen;〃 Edmunds was saying。 〃Were recording at equivalent of half a million ASA; so thats ample。 The real problem is backscatter。 Were constantly fighting it。〃
Norman said; 〃I notice your support team is all women。〃
〃Yes;〃 Barnes said。 〃All the deep…diving studies show that women are superior for submerged operations。 Theyre physically smaller and consume less nutrients and air; they have better social skills and tolerate close quarters better; and they are physiologically tougher and have better endurance。
''59'' The fact is; the Navy long ago recognized that all their submariners should be female。〃 He laughed。 〃But just try to implement that one。〃 He glanced at his watch。 〃Wed better move on。 Ted?〃
They went on。 The final cylinder; E Cyl; was more spacious than the others。 There were magazines; a television; and a large lounge; and on the deck below was an efficient mess and a kitchen。 Seaman Rose Levy; the cook; was a redfaced woman with a Southern accent; standing beneath giant suction fans。 She asked Norman whether he had any favorite desserts。
〃Desserts?〃
〃Yes sir; Dr。 Johnson。 I like to make everybodys favorite dessert; if I can。 What about you; you have a favorite; Dr。 Fielding?〃
〃Key lime pie;〃 Ted said。 〃I love key lime pie。〃
〃Can do; sir;〃 Levy said; with a big smile。 She turned back to Norman。 〃I havent heard yours yet; Dr。 Johnson。〃
〃Strawberry shortcake。〃
〃Easy。 Got some nice New Zealand strawberries ing down on the last sub shuttle。 Maybe youd like that shortcake tonight?〃
〃Why not; Rose;〃 Barnes said heartily。
Norman looked out the black porthole window。 From the portholes of D Cyl; he could see the rectangular illuminated grid that extended across the bottom; following the half…mile…long buried spacecraft。 Divers; illuminated like fireflies; moved over the glowing grid surface。
Norman thought: I am a thousan
