Item #: SCP-980
Object Class: Euclid
Special Containment Procedures: SCP-980 Is to be contained in Site-██. Its containment chamber will be accessible through a single decontamination room between two airlocks. The room will be under 24 hour surveillance, and any activity should be immediately reported to site command. The room will be maintained in hard vacuum at all times, and no ventilation systems are to be connected to the containment room. Any objects removed from SCP-980, or recovered from inside, are to be catalogued SCP-980-X in the order they are recovered. To date, 2 samples have been recovered, and are stored in a secure storage locker in Site-██ (See Addendum-980-3)
Description: SCP-980 is an object approximately 250m in length, with a maximum width of 75m and a maximum height of 60m. Determined to be a craft of extraterrestrial origin. Sixteen protrusions extend from points along the surface of the object in a symmetrical pattern. There are also four apertures in symmetrical formation on what has been determined as the 'bow' of the vessel. The stern is dominated by a cluster of eight large pods connected to the primary hull, each one has a concave indent in the back. Hull composition is a form of complex carbon nano-tube structure that has been found to be nearly impossible to damage, able to withstand extreme heat up to 5500°C, (See addendum-980-1). The protrusions appear to be some form of weapon system, though each appear to be heavily damaged, portions missing and heavily charred. Additionally, the outer hull shows extensive scarring and cratering, most of which is located along the ~100 meters of the aft of the vessel. Surface scans have revealed four access points located along the object, (See addendum-980-2).
Inside the object is an atmosphere of unknown composition. Chemical analysis revealed ████ unknown compounds some of which [DATA REDACTED] resulting in the death of █ researchers before the sample dissipated. It maintains pressure despite containment protocols, and maintains itself at roughly one one-hundredth atmospheric pressure. It has been shown to resist the vacuum state of the containment chamber. It is unknown how the internal atmosphere of the vessel achieves this effect.
Addendum-980-1: When research team first attempted to remove samples of the outer hull of SCP-980 it was shown to be extremely resilient to damage. The first attempts utilised tungsten-carbide saws and diamond edged saws. Both wore away before any meaningful progress could be made. A further attempt using a chemical cutting laser resulted in the beam refracting wildly off the hull, destroying the emitter system used. It appears that the beam passed into the outer layer of hull before reflecting off of a deeper layer of another, unknown material. The beam was scattered wildly back at a fraction of its original power.
Addendum-980-2: When Infra-red scans of 980 were taken, four circular locations measuring approximately 3m in diameter were discovered. Further inspection revealed that directly adjacent to each location was a discoloured point on the hull measuring approximately .5m, in diameter. Further testing showed that applying direct concentrated pressure on the centre point of the discoloured location causes the adjacent location to melt away into the surrounding hull. It was at this time that it was discovered that the inside of the object was in a state of negative pressure. Two nearby researchers were pulled inside, the aperture closing before they could exit. Muffled screams were reported for ██ minutes. Exploration of the internal structure ordered by 05-█
Addendum-980-3: Samples recovered include one sample of the outer hull9SCP-980-1), recovered with much difficulty, one sample of the inner layers of hull(SCP-980-2), retrieved from one of the damaged portions, and one sample of the internal atmosphere(SCP-980-3). (See exploration log 980-1). SCP-980-1 appears to be a semi-transparent form of crystalline matrix composed of complex carbon nano-structures. This material is extremely heat and impact resistant. The sample itself does not reflect light. However, SCP-980-2 has been shown to reflect most wavelenths of the electromagnetic spectrum, it's composed of [DATA REDACTED].

SECURITY CLEARANCE LEVEL 4 REQUIRED.
Further Exploration into SCP-980 pending 05 approval, and further analysis of internal atmosphere composition.
