Titan. Stephen Baxter
She was woken by a buzzer alarm, at 4 a.m. It felt as if she hadn’t slept at all.
They prepared a hasty meal: tinned fish and potatoes, tubes of soft cheese, and a vegetable puree that had to be reconstituted with hot water. The rations were Russian standard, and, as usual, tasted salty and heavy with butter and cream to Mott. She drank sweet coffee from a plastic bag with a roll-out spout. She tried not to drink too much; she was going to be in her pressure suit for a long time.
Libet went down to the Soyuz to run a final check, and Mott got herself dressed in her stiff Russian-design pressure suit.
Libet suited up in her turn, and they pressurized each other’s suits, making sure they were airtight. Then Mott tested her pressure-release valve, a large knob on the suit’s chest panel.
She pocketed some souvenirs: her Swiss army knife, photographs.
By six a.m. they were both ready to leave.
A TV camera was mounted in one corner of the Service Module, all but concealed amid the equipment lockers and cables there. The camera was mute, no red light showing. It looked as if nobody wanted to record these last acts of the American manned space program, two unhappy astronauts clambering into Russian pressure suits.
Mott led the way for the last time out of the Service Module and through the FGB towards Soyuz. Behind her, Libet killed the lights in the Service Module.
The waiting Soyuz was stuck on the side of the FGB, nose-first.
She could see through blister windows in the FGB that the body of the ship was a light blue-green, an oddly beautiful, Earthlike colour. The Soyuz looked something like a pepperpot, a bug-like shape nine feet across. Two matte-black solar panels jutted from its rounded flanks, like unfolded wings, and a parabolic antenna was held away from the ship, on a light gantry. Soyuz was basically a Gemini-era craft, still flying in this first decade of a new millennium. And today, Mott and Libet were going to have to ride Soyuz home.
The Soyuz was strictly an assured crew return vehicle, in the nomenclature of the Station project, a simple mechanism for the crew to make it back to Earth in case the Shuttle, the primary crew ferry, couldn’t make it in some emergency. The Mission Controllers, down in Houston and Kalinin, had decided that the Columbia incident and subsequent Shuttle grounding constituted just such an emergency.
The Soyuz’s Orbital Module was a ball stuck to the craft’s front end, lined with lockers, just big enough for one person to stretch out. It would be discarded to burn up during the reentry, so Mott and Libet had packed it full of garbage. Now Mott had to struggle through discarded food containers and clothing and equipment wrappers, many of them floating around, to get through to the Descent Module. It was like struggling through a surreal blizzard.
The Descent Module, the headlight-shaped compartment in which they would make their return to Earth, was laid out superficially like an Apollo Command Module, with three lumpy-looking moulded couches set out in a fan formation, their lower halves touching. There were two circular windows, facing out beside the two outer seats. Big electronics racks filled up the space beneath the couches, and a large moulded compartment on one wall contained the main parachute. Mott slid herself in, feet-first, wriggling until she could feel the contours of the right-hand seat under her. The seat was too short for her, and compressed her at her shoulders and calves.
There was a small, circular pane of glass at Mott’s right elbow. She peered out of this now, trying to lose herself in the view of blue Earth.
After a few minutes, Libet floated headfirst into the compartment. She pushed the last of the garbage back into the Orbital Module, and dogged the hatch closed. Then she somersaulted neatly and slid into the center couch, compressing Mott against the wall; their lower legs were in contact, and there was no space for her to move away.
The two of them began to work through a pre-entry checklist.
At a little after 9.00 a.m., it was time for the undocking. The clamps that held the craft together were released. A spring connector pushed at the Soyuz; there was a gentle thump, and the Soyuz drifted gently away from Station.
For an hour, Libet used the Soyuz’s crude hand controller to fly the ferry around Station. Mott was supposed to take a final set of photographs of the abandoned Station before the descent. She had to sit up out of her couch and wedge herself in the small porthole to get the shots.
Mott could see the whole assembly, floating against a curving horizon, with the meniscus of clouds masking the ground below. In the light of Earth, Station was brightly illuminated, a T-shaped mélange of greys, greens, whites. It looked quite delicate and beautiful.
The unfinished Station looked pretty much like Mir had, in an early stage of its construction, she supposed. The two main blocks, both orbited by Russian Protons, were the Service Module, a three-crew habitat based closely on the Mir’s base block, and the FGB, based on the Mir’s Kvant supply module. The two modules were squat cylinders, docked end-to-end, punctuated with small round portholes, and coated with thermal insulation, a powdery cloth that was peppered by fist-sized meteorite scars. Small solar panels stretched out to either side of each module, like battered wings, with big charcoal-black cells and fat wires fixed in place with crude blobs of solder. A Progress unmanned ferry, another Soyuz variant, was docked to the Service Module’s aft port, on the other side from the FGB.
On the forward port of the FGB was docked the main American contribution to date, a small module called Resource Node 1, which had provided storage space for supplies and equipment, berthing ports, a Shuttle docking port, and attachment points for more modules and the Station’s large truss: a gantry that would have stretched all of three hundred and sixty feet long, with the huge photovoltaic arrays stretching out to either side.
But the assembly hadn’t got that far. Only the first piece of the truss, a small complex element called Z1, had been hauled up by Endeavour and fitted to the top of Node 1. Future flights would have brought up more truss segments, the comparatively luxurious US habitation module, and the multinational lab modules, sleek, modern-looking cylinders the size of railway carriages which would have clustered closely around the Resource Nodes.
In fact, the completed Station would have looked, she thought, like a collision between the twenty-first century and the twentieth – the modern American design, components and concepts inherited from the billions invested in abortive Space Station studies since 1984, forced together with a second-generation Russian Mir.
It was all such a waste.
If they’d flown up one more mission, STS – 94, at least they’d have had a serious science facility up here. STS – 94 would have been the fifth US assembly flight; it would have delivered the first US lab module, complete with thirteen racks of science equipment, life support, maintenance and control gear. And they would have been able to do some real work up here, instead of the small-scale make-work experiments they’d had to run: monitoring herself for drug metabolism by taking saliva samples, checking for radiation health with miniature dosimeters strapped to her body, checking her respiration during exercises on the treadmill, investigating the relationship between bone density and venous pressure by wearing dumb little tourniquets around her ankle …
STS – 94 had been scheduled for early 1999. Delays, funding cuts and problems with the early Station modules and operations had pushed back its launch five years. And now, it would never fly, and Station would never be completed.
Soyuz was passing over South America. Mott could see the pale fresh water of the Amazon, the current so strong it had still failed to mingle, hundreds of miles off shore, with the dark salt ocean.
The retro rockets fired with a solid thump. For the first time in four months a sensation of weight returned to Mott, and she was pressed into her seat.
When the burn was done, the feeling of weight disappeared. But now the Soyuz was no longer in a free orbit but was falling rapidly towards Earth.
There was something wrong with her eyes. She lifted up her hand, and found salt water, big thick drops of it, welling over her cheeks.
She
