“Will. Jack,” the lead suit man smiled.
“Colonel,” Enright greeted.
“I have new faceplate visors for you both,” the Colonel said as he carefully removed two flat bundles from his briefcase.
The two pilots glanced sideways at each other.
“Oh?”
“They’re new but thoroughly tested, Will. Made by Hughes Radar Systems Group for the Navy. They’re designed to reflect laser light. The visors should protect your eyes in the vicinity of LACE on-orbit. We’ll replace your sunshade visors with these. We’ve already put one on Jack’s EVA suit in the ship.”
The new helmet visors were phosphate glass coated with special dye for absorbing laser beams before they can penetrate a pilot’s eyes. Until the dye loses its effectiveness after three weeks’ exposure to air, the visors would be 18 times stronger than normal sunglasses for eye protection.
Before the pilots could respond, the man in blue was fiddling with the neckring of Colonel Parker’s helmet. In an instant, the officer had lifted Parker’s white helmet from his head. Another technician helped Enright doff his helmet. An Air Force man pulled two, nickel-size circular patches from his pocket.
“Gonna blindfold us?” Parker asked with a grin.
“Not quite. These patches are soaked with a new drug for motion sickness. All past shuttle crews have experienced Day One motion sickness when they started moving around the cabin too soon after launch. These patches are made by Ciba and are laced with Transderm-V Scopalamine. Your skin will absorb the medication for at least two days from the patch. You should be able to get out of the seats fairly quickly. Here.”
The officer unwrapped one of the patches and laid its adhesive side to the back of Parker’s ear. The suit technician took the second patch and stuck it behind Enright’s ear.
Next, the DOD man and his colleagues in white coveralls began working on the two white helmets. They worked to disconnect the helmets’ normal sun visors attached above the clear faceplate atop each helmet. The sun visors on each helmet were removed and anti-laser visors protected within a blue cloth wrap were snapped into place on each helmet.
“There you go,” the Colonel from the Department of Defense smiled as he took a step backward to admire his work. “Just what everyone is wearing these days.”
“Or should be,” Enright grinned. Only his partner shared his chuckle.
“We thank you,” Parker said as he eased his head into the helmet. Each pilot twist-locked his helmet to his suit’s neckring.
“Do good work, boys,” the Defense Department man said firmly.
“The best, Colonel,” the pilot in command replied with words full of Can-Do.
Returning to the crowded hallway, the new prime crew pressed toward the brilliant sunshine at the hall’s double doors. With a turn to the group in the hallway and a wave from each flier, the two airmen climbed the steps into the transfer van for the ride to the base of Pad 39-A. Only Enright noticed Colonel Parker grimace as he lifted his right leg to the steps.
Parker and Enright were silent in the van as it rode the causeway from the crew quarters. Their faces were happy in the warm sunshine bursting through the van’s tinted windows. The milk-truck van was full of Go. As they drove toward their ship, Colonel Parker thought about his dawn, pre-flight medical examination. Silently, he smiled into the morning sunshine.
“You know you can’t fly with that leg, Will.” The physician from the Aeromedical Certification Branch looked angry. “How the hell could you keep that leg to yourself for a month without telling us?”
“I know, Mike, I’m sorry. But I knew you would pull my ticket.”
“Consider it pulled, Will.” Michael Gottwalt looked sadly at his old friend in the examination room of the Cape’s crew quarters at daybreak. “You simply cannot go with that leg. I’ll inform the Flight Director.”
“Mike, you owe me. Just one. Damn, we’ve known each other since Genesis. In 20 years, you’ve seen places on me my wife never saw. I’m asking you for one final mission. Two days up there won’t kill me. I’ve been hopped up on antibiotics for the last week. Swelling is down. And I can live with the pain . . . Please.”
Dr. Gottwalt stuffed his hands into the pockets of his white coat, well rumpled and coffee stained. He looked intently at his patient and his friend.
“We just about go back, you and me, to wooden wings and iron men, Will.” Michael Gottwalt smiled. “We came onboard together with Gemini in ’62. We grew up together here . . . Tell me about the fever, Wifi.”
“None for two days, maybe three.”
“You’re a tough old cowboy, Will Parker.” The physician with the good face smiled at his friend. “You always did aim high.”
“Perhaps.” The tall flier hopped down from the examination table. He pulled on his fishnet woolies worn under the heavy orange pressure suit. “Well, Mike?”
“I suppose they’ll jerk both our tickets . . . I’ll sign you off . . . But I tell you this: You damn well better come home in one piece, you and Jack.” The physician did not smile.
“Haven’t bent one yet, Mike. I have a supply of medication already stashed in Endeavor. We’ll be fine.”
The physician only nodded. He watched his old friend open the heavy door to the hallway. With one foot outside the narrow examination room, Will Parker looked back over his shoulder.
“It’s funny, Mike, looking back. I guess I have aimed high. But you know, in all the years, I can still remember the highest ambition of them all: All I ever really wanted from this life was to walk Kathy Turner home from high school. Even once.” The tall command pilot smiled with a gentle, faraway look in his gray pilot’s eyes.
“Did you ever do it, Willie?”
“Nope . . . Never got the nerve to ask. Be seeing you, Mike.”
The physician stood quietly and for a long time he studied the closed door through which his friend had passed with the slightest limp.
Along the beach, people waited in the humid morning sun to celebrate Endeavor’s launch.
When the little caravan of NASA vehicles stopped at Pad 39-A, Parker and Enright emerged into the sun. Each pilot carried a portable air conditioner plumbed into his cumbersome suit.
With 90 minutes to go, the two airmen stood quietly beneath the purple and cloudless sky. The fliers were in no hurry to end the peculiar brotherhood of their hectic training. They stood side by side and they looked upward to the white starship, their bird, their Glass Lady. From her tail, plumes of white liquid hydrogen vapors, 250 degrees Fahrenheit below zero, swirled in the sunshine at the black nozzles of Endeavor’s three Rocketdyne main engines.
Colonel Parker looked hard at his main engines. Before Challenger’s first flight on Shuttle Six in April 1983, the ship had been grounded for four months when all three of her main engines were found to have cracked fuel lines. Five years before that setback, a report by the National Research Council Assembly of Engineers had warned NASA about shuttle engine weaknesses. But their warning had gotten lost in the shuffle of federal paper. And in June 1984, the STS-12 countdown for Shuttle Discovery’s maiden flight had ticked down flawlessly to minus six seconds from lift-off when her main engines ignited for 2½ seconds and then burped stone-cold dead—four seconds before the solid rocket boosters were to fire. Shuttle Discovery went nowhere. Had Discovery’s main engines failed on Shuttle’s twelfth mission only five seconds later—after the solids had ignited—Discovery and her ship’s complement of five men and one beautiful dark-eyed woman very likely would have become one great grease spot.
Standing at Endeavor’s tail, Parker and Enright took the communion of their ship, whose black tiled nose pointed skyward. Standing quietly, with their pilots’ eyes and hearts they kicked the tires.
A ship of the line poised to rip open the sky is a living thing, a breathing thing, a pregnant thing. Like a roundly pregnant mare searching for her private meadow in which to foal, a fueled starship fumes potently, anxious to leave behind
in her white-hot wake the probing fingers of her keepers.
There is an urgent noise about a spacebound vessel at the ready. Pipes whine and clank like a pot-bellied stove as super-cold propellants settle and flow in tankage and plumbing. Vents and purge ducts belch frothy steam and icy vapors as the coldest cold sends plumes percolating into the humid air.
To describe Shuttle as weights and measures is to describe birth as only ganglia, neurons, and synapses. The shuttle, like the human organism which birthed her, is greater than the sum of her parts.
Two solid rocket boosters, the SRB’s, strapped to Shuttle’s external tank, stand silently. Each of these 149-foot-long silos holds 1 million pounds of explosive. Once lighted, each SRB spits 2,700,000 pounds of thrust for 122 seconds from the largest solid rocket motor ever built, the largest moveable rocket nozzle ever fired, at nozzle temperatures in flight of 5,600 degrees Fahrenheit. Words pale. The energy of the two SRB’s is known only by their vibration, which starts in the heels of an observer standing five miles away and travels up his body until the teeth ache.
The great external tank sweats frost from its 66,809 pounds of metal pores, where 140,000 gallons of supercold liquid oxygen sit atop 380,000 gallons of super-cold liquid hydrogen. Inside, some 1,561,816 pounds of propellant churn with the same energy with which God fashioned heaven’s first molecule of water.
The scent of Go excreted from Shuttle’s glands, like deer musk in November, rides the still, humid air. Go is in the wind, it clamors in the ears, it penetrates the steel launch tower, and it reverberates into the earth and into the hearts of Shuttle’s stewards. The Go engulfs a body until it sweats out moistly on the palms.
With their eyes and their legs, Parker and Enright felt the presence of their ship enter their bodies, surge through their plasma, and tingle their nerve endings.
“Let’s do it, Number One,” Colonel Parker, Astronaut, said firmly through his open faceplate as he led Enright into the gantry elevator.
“Right behind you, Skipper.”
Atop the launch tower in the White Room, 147 feet above the sand, Parker and Enright were met at the catwalk leading to Endeavor by the former prime crew of the mission.
The two suited fliers stood awkwardly before the dispossessed crew who had emerged from Endeavor’s flightdeck.
“We’re ahead of the timeline on the flightdeck, switch position protocol,” the bumped command pilot smiled lamely.
“Thanks, buddy,” Colonel Parker nodded.
“This is from us ’cause you and Jack need it.” The displaced mission commander reached behind toward his own crewmate. The pilot handed Parker and Enright a new, yard-long, toilet plunger with a bright bow festooning its wooden handle.
Colonel Parker held the offering as he and Jack Enright studied it with mock gravity and dignity.
“I know just the place for this,” Parker said with sober resolve through his open faceplate.
“Knew you would, Will,” the pilot in coveralls replied, unable to restrain his broad grin.
The momentary tension evaporated with a four-way laugh among brothers in the humid morning air.
Enright on his hands and knees crouched through Endeavor’s open side hatch. Parker followed him along the narrow Crew Access Arm which reached from the White Room to Endeavor’s glass side. The former crew followed and stopped outside the open hatch.
As Parker bent low to squeeze on all fours through the hatch, his colleague, whose seat had been pirated, reached to Parker to retrieve his non-flight-rated gift, the beribboned Plumbers’ Friend.
Colonel Parker did not hand it back through the hatch. Instead, he pushed the plunger inside to Enright.
“This is mine,” Will Parker smiled warmly.
The serious pilot outside on the catwalk nodded as he peered into the hatch where Endeavor’s mid-deck basement cabin was crowded with her two pilots and two closeout technicians anxious to see the crew take their seats upstairs on the flightdeck.
With the two astronauts and their technicians standing in the mid-deck with Endeavor sitting vertical on Pad 39, the four men actually stood on the mid-deck’s back wall: the “floor” of the upright shuttle. Secured to the wall of the mid-deck, which will be the ceiling when Endeavor is right-side up, was a 280-pound canister pointed toward the open hatchway. The canister contained the shuttle escape pole dreamed up after the Challenger explosion. Should any shuttle experience serious trouble and if the pilots could wrestle the ship into a normal glide toward the ground, the pole would allow the desperate crew to bail out. At least that is what the advertisement says.
As the crippled shuttle coasted toward the ground, the crew would use the pole on the mid-deck ceiling to abandon ship. First, the pilot would have to get his glider down to 40,000 feet. There, the crew would depressurize the cabin which is now allowed since everyone since Challenger wears the heavy pressurized suits. At 31,000 feet, 70 explosive bolts in the mid-deck hatch would be blown and the hatch jettisoned. The spring-loaded escape pole would then be released to extend nine feet outside the hatch-way. When Shuttle reached 20,000 feet, the commander would put her on automatic pilot with instructions to the black boxes to keep Shuttle level at 200 knots flying speed. Each crew member would then hook on to the pole like a telephone man’s safety belt along a telephone pole. They would then jump at 15-second intervals. By scooting down the pole, the pole would steer the evacuating fliers away from the massive wing, missing the wing by 18 feet. The astronauts would then parachute to Earth, arriving about one mile apart.
Parker and Enright grinned at the dubious escape pole installed more for the press after Challenger than for the Shuttle. Some say the astronaut corps calls the nine-foot escape pole “Big Johnson.”
“Bring her back alive, Will,” the displaced pilot called into the open hatch.
“You betcha,” the Colonel smiled as he grasped the man’s forearm firmly for a long, quiet moment across the hatch sill.
Within 10 minutes the crew was strapped into their seats in Endeavor’s nose. Mission Commander Parker lay on his back in the left seat with Enright next to him in the right seat. The closeout engineers carefully recited their checklists as they connected air hoses, restraint harnesses, communications cables and aeromedical sensor cables. Before the technicians left the flightdeck with a firm pat upon each flier’s shoulder, the pilots were busy confirming switch positions from Ascent Book checklists. The cabin was warm in the brilliant sunshine pouring in through the six forward windows and the two overhead windows in the ceiling of the aft crew station five feet behind the pilots’ seats.
“Endeavor: Comm check.”
“With you five-by, Flight,” the pilot in command answered.
“Copy, Endeavor. At T minus 70 minutes, we have hatch closed and sealed. We’ll run the cabin pressure integrity tests by hardwire from here.”
“Okay, Flight. Thanks,” the Mission Commander drawled slowly.
Shuttle is pressurized with a normal air mixture of one part oxygen to four parts nitrogen. This mixture is maintained at sea level pressure of 14.7 pounds per square inch on the ground and in space. Cabin air is supplied by the ship’s Atmosphere Revitalization System, the ARS.
Shuttle’s environmental control system is a maze of plumbing, pipes, heat exchangers, and space radiators, all manufactured by Hamilton Standard.
The ARS is the lungs and the sweat glands of Shuttle. Like the hands which created her, Shuttle keeps her iron bowels cool by sweating water from her aluminum pores. Heat from Shuttle’s vital organs and black boxes, and from the bodies and the breath of her crew, is absorbed by two water loops. Water circulates through each loop, picking up heat along the way. That heat is transferred to twin freon coolant loops. The freon refrigeration fluid carries the heat to tubular radiators attached to the inside of each of the two, 60-foot long doors of the payload bay. In space, when the doors are opened, the radiators in the shade of Shuttle’s wings radiate the freon’s heat into the cold of space, like a per
spiring athlete spreading his wet arms wide to a cool breeze.
During launch and the fiery re-entry from orbit, heat is sweated out as steam by two flash evaporator units inside Shuttle’s tail section. During the last minutes of re-entry and landing, two ammonia boilers sweat out the heat load from the freon loops.
“Endeavor: At T-51 minutes, we’ll be aligning the IMU’s at this time. And you can crank up the water boilers now.”
“Rogo, Flight,” Parker replied.
In Shuttle’s nose, three Inertial Measurement Units, IMU’s, were being fine-tuned to feel the ship’s way into space. Each IMU is a complex array of motion and acceleration sensors which “feel” Shuttle’s position and where she is going. Just as a child’s spinning top wobbles as it winds down, so the IMU’s wobble from precession and must be realigned to proper positions. The IMU alignment is a computer-generated order which tells the IMU gyroscopes where Shuttle sits at Pad 39 and where she is bound: A tiny needle’s eye in space 800 miles to the east. “Where am I now?” the sealed black boxes in Endeavor’s avionics bay demand. And the computers reply: “You stand with your tail feathers in the sand at Cape Canaveral, Florida, 28 degrees, 36½ minutes north latitude by 80 degrees, 36¼ minutes west longitude. When you leave the ground, you must twist your tail, which now points southeast, until it points northeast so you will cross the Equator half a world away at an angle of thirty-eight degrees.” And a world away, ninety minutes from lift-off, the IMU’s must find their whirling target, LACE: Hitting a bullet with a bullet, each traveling at a velocity over the Earth of 25,460 feet per second.
