member of the MPG, was in top physical shape. As such, except during heavy exertion, the extractor on his suit would be able to supply the tank faster than he could breathe it down. This meant he could stay outside all day if necessary, urinating into a sponge device inside his shorts and drinking water from the small storage vessel that fed a straw in his helmet. Only the need for food or defecation would force him inside; two biological functions that were addressed in the military version of the biosuit but not the civilian version.
Lon gave his helmet a final twist, locking it into place. A small green light appeared in the corner of his visor display. This told him that the seal was intact and the suit was ready for activation. He spared a glance over at Brent, seeing that he was still struggling to pull his own suit tight over the bulk of his body. Brent was not a member of the MPG and was not particularly fond of physical exercise. What he was fond of doing was sitting in a bar or at home and smoking bag after bag of cheap marijuana, which in turn led him to eat quite a bit of food. The result of all this was that he was more than twenty kilos overweight and that he tended to draw more air from his biosuit than it could replace, even during non-exerting work. This technically placed him in violation of safety standards for an outside worker but IFP management had always looked the other way about it. As long as the work got done, IFP had not cared how it was accomplished or whether or not it was accomplished safely. But now that IFP management had been replaced by Agricorp management, who had already proved to be much more stringent and nit-picking about such things, Lon wondered if Brent's next physical exam was going to be his last. But then there was a strong possibility that neither one of them were going to even make it to their next annual exam. The blue collar workers of the former IFP force were still awaiting word on the inevitable merger-related 'elimination of positions' that came every time two companies became one. Usually, especially when Agricorp was involved, it was the smaller of the two merged company's workers who bore the brunt of the cuts.
'Suit computer,' Lon said into the throat microphone, addressing the voice-activated circuit that controlled the suit. It was necessary to address the computer by name, such as it was, so that it would not inadvertently mistake some aspect of normal conversation for a command. 'User logging on.'
'Go ahead,' said the artificial, vaguely male voice that the cheap computer had been programmed with.
'User Lon Fargo. 897-78-98-9876-34.'
The suit computer quickly accessed the Internet via a cellular antenna in the far corner of the greenhouse. It then accessed the Agricorp main intranet for Martian operations, searched its employee databanks and found that that name matched that social security number and that that employee was currently authorized to utilize an Agricorp biosuit. It then compared Lon's voice pattern with the pattern it had stored and concluded that they were both the same. This took a little over two and a half seconds. 'Log on accepted,' it told him. 'Awaiting command.'
'Suit computer,' Lon said, 'testing procedure.'
'Stand by.' The computer performed a complete safety check of all seals and circuits. This took nearly ten seconds. When it was done and satisfied that Lon would not be decompressed if he stepped outside, it said: 'Test complete. Your suit is functioning properly.'
'Nice to know,' Lon muttered. 'Suit computer, activate suit.'
'Activation in progress,' the computer answered.
Lon took a deep breath and braced himself. The activation sequence was not painful by any means, at least not if the suit was being worn correctly, but it was not exactly one of life's great pleasures either. He felt the entire surface area of his body, from the bottom of his neck downward, being slowly compressed. For a moment it was difficult to breathe at all as the plastic constricted the rise and fall of his chest. But once the proper pressure was reached, the constriction eased up, allowing free movement. No sooner had the body section pressurized than the hissing of air against his face began. That was the pressurization of the helmet portion of the suit. The air had an industrial, almost chemical smell to it that was actually caused by the delivery system, not the air itself.
'Activation complete,' the computer told him when it was done. 'All systems working properly.'
'Suit computer, activate radio link with suit uh...' he paused to look at the number stenciled on the right sleeve of Brent's suit. He had to read it sideways since Brent, having just successfully closed his body inside, was putting on his helmet. 'Five seven five nine three two... uh six.'
'Link established,' the computer said. 'Be advised that the specified suit is not currently active.'
'No shit, dickwad,' he replied. The computer said nothing in return, had in fact not even heard his remark since the proper salutation had not prefaced it.
It took another two minutes for Brent to go through his safety check and activation sequence. Once he was done and had his radio link active, he looked over at Lon. 'You ready,' he asked.
'I'm ready,' Lon said. 'Let's do it.'
He walked over to a control panel on the truck and opened the access hatch. A small computer screen was beneath it. He activated the screen and instructed it to link up with both his and Brent's suit computers. It asked for authorization in the form of names, social security numbers, and voiceprints. They provided this information. Once that was complete Lon instructed the truck computer to power up the airlock at the end of the boom.
'Airlock active,' replied the truck computer over their radio.
The airlock was nothing more than a steel box, two meters square by two meters deep. At the top was a synthetic rubber cushion that would form a seal against the roof of the greenhouse. Lon and Brent stepped onto the back of the truck and picked up their two large tool chests, which had been stored against the hydraulic housing. Lon swung his leg over the side of the airlock first, the thin material of the suit allowing almost normal range of motion. Once he was inside, Brent handed him the tool chests, hoisting them up and over with absurd ease although, had they been in 1G, they would have weighed more than thirty kilograms each. Lon set them on the floor and Brent hefted his own bulk into the box. With the two of them inside, the quarters were a little cramped but they would only have to put up with it for a few minutes.
'You all set?' Lon asked, putting his hands on the boom controls. The glove portions of the biosuits were thin and were designed to allow as much dexterity of the fingers as possible but even so, any fine movements were awkward. As such the controls were overly large.
'Take us up,' Brent told him, settling in against the wall. 'Let's get this shit over with.'
Lon pushed upward on the control yoke and the hydraulic boom began to extend, moving the airlock upward and outward. The roof access panel was 1.5 meters square and set into the glass of the ceiling twenty meters above the road. It was marked by an outline of black paint. The idea was to make sure that the entire outline was within the airlock before the panel was opened. If it were not, an explosive decompression would occur when the hatch was opened, causing the blast doors in the 500 meter quadrant around the hatch to come slamming upward from the underground panels in which they were housed. Though the blast doors would protect everyone beyond the immediate quadrant, those unprotected workers inside of it would die a nasty death of decompression and suffocation. Lon's aim with the boom was at its usual level of perfection. The rubber seal pressed firmly against the glass leaving the black outline in almost the exact center. A flip of a switch caused the airlock's hydraulic system to apply constant upward pressure, making the seal airtight.
'Truck computer,' he said. 'Decompress airlock.'
'Decompression sequence in progress,' the computer replied.
From below them the powerful exhaust fans began to remove the air from the inside of the lock and expel it out into the greenhouse. The airlock would not be reduced to a complete state of vacuum, as would have been the case had they been in space, but would instead be reduced to the atmospheric pressure outside. The outside air pressure was a greatly variable number on Mars. It changed constantly from day to day as vast portions of the mainly carbon dioxide atmosphere were constantly frozen and thawed and refrozen in the polar regions of the planet. The truck computer automatically established a link with the Martian Weather Bureau, which kept track of current conditions, and downloaded the latest barometric reading. Of course in addition to the constant shifting of pressure due to polar freezing, the pressure was different from place to place depending upon elevation as well. And, unlike on Earth, there were no oceans in which to base a standard 0 elevation. The MWB, as did the rest of Mars, used the elevation of New Pittsburgh, Mars' first settlement, as its standard. Since the Eden area greenhouse was nearly a thousand meters lower in elevation than New Pittsburgh, which sat atop a huge plateau, the computer had to do some adjustments of the figure it received. This was all a standard part of living and working in an environment where human beings were not meant to live and work. Most Martians hardly gave such things a thought although they frustrated Earthling to hysterics at times.
'Decompression complete,' the computer told them ninety seconds after it had begun. 'Airlock seal is intact. It is safe to egress.'
