Written in 365 Parts: 193: Inside

It had proven surprisingly easy to board the Generation Ship. The climb up to the side of the airlock, on the inside wall of the asteroid, was tedious as they moved very slowly. They did not wish to slip and hurt themselves, or reveal their presence with any loud noises this close to the structure. From the side of the airlock they were able to get a better view of the structure of supports as they attached to the Generation Ship itself. They saw that there were large magnetic graples that held the vessel and these were powered from the cradle, this gave more weight to the idea that there was independent power inside the vast dock.

Once they were above the airlock, and now close to the top of the Generation Ship, they could see that the airlock was a solid steel structure. The collapsing sections that provided a buffer between the outer rock doors and the ship were massive steel concertinas. They had room to flex, but it resembled overlapping armour plating more than an airlock tunnel. From this position they could also see the large compressors that were needed to open the hanger doors. 

Separate to the compressors and running parallel to the twin airlocks was a feed pipe that no doubt held cables and other feeds. It was attached to the rock wall and outer airlock and also attached to the Generation ship on the other side of its hangar airlock. Clearly it was where power and other essential supplies could be provided to the ship. It would make sense that the Generation Ship would have tanks for water and fuel near to its hangar and these had to be supplied somehow.

Drick and Marsh had examined the pipe. It was large, over six metres in diameter. It was constructed from a composite of steel and carbon. Of more interest to Drick was that it had an external access hatch that was an airlock in itself. The pipe was pressurised, this was probably a maintenance hatch. Drick had carefully examined the lock on the door and was delighted that it was a very simple model. The lower security had to be due to the hatch being inside the asteroid.

After a few minutes Drick had managed to connect to and then infiltrate the locking mechanism. A moment later they had uploaded a virus into the security system. This was similar to the package they had used on the tower assault. It was more like a series of viruses, together they had a low level intellect. Marsh briefly wondered if using this class of software wasn’t overkill for what was clearly a low-level maintenance security system, but he had neither the skill, or the luxury, to quiz Drick over their actions.

Within seconds they had gained access to the lower levels of the security sub-net that was running the maintenance systems. It would be connected to the systems above the Generation Ship and Marsh had little doubt that the software would start stealthily working on those systems as well. 

This access was enough to enable Drick to piggyback the security cameras and sensors in the massive tube and determine its purpose. As they suspected it was a supply tube. Filled with long electrical cables, water supply pipes, gas pipes, and a single fuel hose in a heavy protective casing. Their suspicions were right. This tube was used to supply ships that docked, or were berthed, inside the large Generation Ship. 

The fuel pipe was for liquid hydrogen, used in small manoeuvre jets, there would likely be an oxygen supply but it made sense that this wasn’t located in the same tube. The pipe was old, but not as ancient as the mighty vessel it was attached to. They had some small metallurgy sensors that estimated the maintenance tube at around half the age of the hull of the generation ship based on standard patterns of decay.

Propulsion gases were still relatively common for thrusters on a variety of craft. The fuel was likely needed to replenish the vehicles that docked with the Generation Ship. It was unlikely needed for any vessels the Generation Ship had berthed inside. For some reason they had decided to use this pipe which was fitted to exterior tanks than use the Ship’s supplies, or convert internal systems to hook up to modern designs. Perhaps there was some issue with modifying the massive vessel. From what Marsh had read the vessels were custom built, so maybe the fixtures and fittings were too arcane to bother with retrofitting and the use of supplementary supply was easier.

Drick studied as many details as possible and noted to Marsh that the fuel and energy supply ran to a reserve at the rear of the asteroid that could be refreshed externally. They had not seen a hatchway or refueling platform on their scan of the outside of the rock, but it was likely hidden in a similar fashion to the docking bay doors. The best guess was that the vessel they had followed could be replenished hundreds of times from the reserve. It was a good guess that it was not the only visitor to this vessel.

After disabling the alarms, placing cameras and sensors into loops with enough variance that the entry and exit points of any looped reading could not be easily detected, Drick and Marsh entered through the hatchway. The passageway they found themselves in was cramped, but they could move freely. They quickly moved to the other end of the tube where there was a double airlock on the inside of the pipe that led directly into the generation ship. Drick spent another short time making sure there were no extra security systems or alarms. Then Drick attached themselves to the control panels on this side of the maintenance and supply pipe and uploaded another package of viruses. Marsh couldn’t read Drick’s facial expressions, but he was slightly intrigued at the size of the upload. He figured Drick was making sure that they controlled this pipe and its two airlocks, maybe making sure they had a safe exit route.

Once finished Drick quickly disconnected and stowed the thin fibre cables in a skin-pouch under their arm. Then Drick opened the airlock and they went inside the vessel.
