- The Photon Drive, a propulsion engine in development since 2050, enters its release stage. It brought about a new age, the First Space Pioneer Era, where many interstellar spaceships were deployed to conduct research on star systems as far as 10 lightyears away. Spaceships traveled to the Alpha Centauri system (Toliman and Proxima), Epsilon Eridani system (Ozma), and the 61 Cygni system (Exia), where they discover planets capable of sustaining life (such as Corneus) or with terraforming attributes (such as Exia 2).
- In commemoration of these discoveries, the A.G. (After Galactic) epoch is born. This designation becomes common in use from 2100, next to the pre-existing A.D. epoch.

- The first space-time jump drive, “Warp Drive,” is developed and enters its release stage. With it, humankind expanded their frontiers to the far reaches of the galaxy, paving way to the Second Space Pioneer Era. The term “Earthian” and “Galaxian” is born.

- In order to face the extraterrestrial threat, the UGSF initiates “Project D.” Various technologies obtained from the UIMS and UIMSΔ are evaluated and adopted into the UGSF. This made it possible for the UGSF to reduce the size, and increase the performance and firepower of the UGSF spacefighters. The technological application adopted became a long running standard used among future spacefighters.

- The technology acquired from the UIMS made it possible for the United Galaxy to conduct large scale immigration across the galaxy, bringing about planetary modifications. As a result, 60 star systems came under United Galaxy order, with a total of over 40 billion in population residing within those star systems.

▶ Bosconian
- Following Galaga, a new extraterrestrial lifeform, the ETI-2 (Next Extra-Terrestrial Intelligence), is discovered. These lifeforms created bases within the United Galaxy star systems, and quickly began occupation of their surrounding territories. In accordance to negotiation protocols, the United Galaxy tried to initiate friendly contact with these lifeforms, followed by a warning, and finally intimidation, to all being replied with force. The UGSF completes their analysis of the enemy force, and codenames them “Bosconian.” With the analysis complete, the UGSF moves to deploy their means in facing the Bosconians, the “Blaster” spacefighter.
- Within the same year, the Bosconians abandons and retreats from their bases within the UGSF star systems. These abandoned bases are claimed by the UGSF, and through research of these facilities, the UGSF gains further information regarding the Bosconians. Not making waste of these bases, the UGSF incorporates them for their use.

▶ Blast Off
- The second wave of Bosconian attacks commence. This time, the Bosconians weren’t the only threat. Looming behind the Bosconian attacks were the “Battura,” who would appear hundreds of years later to lay siege against humankind.
