Re: Within the Asteroid
In reply to 'Lucky Jack' McIntyre (msg # 131):
A Vargr-shaped vacc suit wormed its way in to the wrecked corridor. It was Dr. Goezghae, the astro-geologist. She had much experience with asteroids and asteroid ships over the history of human and Vargr spaceflight.
"Allow me." She examined the corridor, the bulkhead and the door, using a tool that combined a video scanner, light and microscope. She paid attention to the airlock seals and reinforcements at the joins, corners and edges.
"I think the hatch is just jammed. There is probably no more air beyond this door for a couple reasons.
"When the unknown body struck this ship and bounced off, the kinetic energy was transferred through the nickle-iron substrate and the ship infrastructure (corridors, ductwork, chambers) both directly underneath the crater and around it. In other words, this whole area flexed inwards, then outwards. The kinetic stress would have been transmitted through this bulkhead, the door, the walls, everywhere.
"Now, I figure we are just at the edge of the sub-impact zone so there was some energy transfer through here. I see micro-fissures (tiny cracks) all over the walls, especially at the joints and corners, and around the hatch. Over hundreds of Earth years air pressure would have been lost. You probably wouldn't notice anything but a gradual loss of pressure over a very long period of time, days or weeks. But it would happen.
"Second, this is not an exterior airlock hatch, it's an emergency hatch and normally kept closed. It's air-tight but not that heavy-duty. Meant to seal a corridor or chamber so that repairs can be made or security maintained. Not designed to hold pressure indefinitely. Yes, there is probably another closed hatch beyond this.
"We can just drill or laser a hole in the wall, see if anything comes out. The laser has a 2mm focal aperture, that should be enough to test without depressurising the space beyond."
