2040: As a part of planned development of the Solar System by uniting of the resources of Russian RosCocmos, the American NASA and the European ESA, the Union Aerospace Company (UAC) was invented. In addition of the development of the near-Earth, and subsequently the entire Solar System, the UAC is tasked with finding and developing new sources of energy to overcome the energy crisis.
2049: During the researches into the processing of the lunar soil UAC invented profitable way of extraction helium-3 on the Moon.
2050: China National Space Administration becomes an UAC member.
2052: UAC absorbs the last private space company, becoming a monopolist in the space exploration niche.
July 20, 2069: the construction of the first settlement on the Moon - Base Armstrong was finally completed. Prior to this, all bases were processing plants with minimum personnel, working on a rotational basis.
2075: The construction of the "Baikonur" orbital shipyard, created to assemble the UAC interplanetary ships, was completed.
2076: "Baikonur" shipyard launched the first interplanetary ship "Tsiolkovsky".
2103: Mars City was founded in the crater of Gale, the first permanent base of the UAC on the planet.
2112: The systematic development of the satellites of the outer planets and the asteroid belt begins.
2135: The UAC completes construction of the "Ares" base in Schmidt crater on Mars - the second largest after Mars City.
2142: The UAC begins construction of the "Gagarin" station in Eris orbit (a dwarf planet beyond Pluto, discovered in 2005 by the Hubble telescope).
2147: Completion of the construction of the "Gagarin" station Traces of an unknown element are found on Mars.
2148 год: - Artificial cavities were discovered by the UAC geological expedition on the earth of Prometheus (Mars). Finding information is classified. Started decryption of an alien language.
- In Chaos Hydraot (Mars), the second outpost of an unknown civilization was discovered. The outpost carried traces of the battle and was hardly damaged. The discovery is classified, research has begun. Decrypted data from the outpost on Earth Prometheus gave the UAC knowledge about the fields of the mass effect. A comprehensive study of this phenomenon has begun.
- The alien language has finally been decoded. The data from the Martian information repositories are made public; the information enforces the humankind to start of the process of reorganizing the UN into a military-political structure of a federal type. The existence of an outpost in Chaos Hydraot remains an internal secret of the UAC, which is kept strictly within the corporation.
- Decrypted data from the object "Hydraot" says that on this base an unknown species was used to study an alternative source of energy, which is several times more energy-intensive than both helium-3 and alien samples from the first outpost. Under the guise of another research initiative in the field of energy, the UAC launches the "Genesis" project , for continuing the researches on a long-extinct alien race. The formation of the Earth Alliance is completed.
2149: - The "Charon" mass relay was found and successfully activated, which transferred the UAC expedition led by John Grissom to the Arcturus system in 38 light years from Earth. To protect against external threats, mankind is launch the construction of a huge military fleet and the formation of the Space Marine corps, despite the fact that people have not yet encountered other intelligent races. UAC loses its monopoly in space exploration.
- As a result of an unknown incident, communication with the "Ares" and "Genesis" bases on Mars is lost. Despite the protests, alarmed by vague explanations and claims that the situation is under the control of the UAC, the Earth Alliance is sending a military expedition to Mars, codenamed "Luminary".
From the chronology the operation "Luminary". Top-secret.
13.06.2149, 9.30 UTC: Two teams (call sign "Alpha" and "Delta") under the command of captains V. Andreev and J. Romero start to land on the territory of the bases "Ares" and "Genesis". General command is provided by Major J. Carmack.
13.06.2149, 10.13 UTC: The initial inspection showed that the territory of the UAC bases was attacked by an unknown kind of enemy forces, using non-standard weapons based on a thermal and chemical effects. Blood leaks and fragments of non-human parts on walls and floors were found, but the bodies of the attackers were not found. Also, teams found the corpses of personnel bases, part of the bodies, presumably, bears the marks of ritual murders. In addition, on the territory of the bases, inscriptions and signs of clearly occult content were noticed.
13.06.2149, 11.15 UTC: The" Alpha" team at the Genesis site entered into a fire contact. Around the same time, unknown persons attacked the "Delta" team. Examination of the bodies showed that the attackers were personnel and military of the UAC. Anomalous traces of decay were found on the bodies, indicating the time three days before the fire contact with the fire teams.
13.06.2149, 13.13 UTC: High-energy reactions were recorded in the territories of the "Ares" and "Genesis" bases, accompanied by flashes of rust-red color and broadband interference in all ranges of communication and surveillance equipment from ultra-long radio waves to hard ultraviolet. As a result, contact with both groups was temporarily lost.
13.06.2149, 23.45 UTC: The flashes that lasted all day on the sites ceased. Group signals are not fixed. Major Carmack decides to wait a day.
06.14.2149, 17.17 UTC: The cruiser reconnaissance equipment receives signals from missing marines from both bases. Of the entire expedition, only four survived.
06.14.2149, 18.00 UTC: The survivors were evacuated from the facilities. Among them, a soldier of the UAC security service was found.
