|This article is about a/an location in Power Rangers Lost Galaxy.|
Terra Venture is a gargantuan spaceship. It is equipped with five engines, each with four rocket exhaust ports, with a core that contains living quarters and a café, and a large city held in the dome at the ship's top; while the city was somewhat uninhabited during the series, it was meant to be the shining capital of the new world. Above this dome is a comparatively small observation deck inhabited by the ship's captain, crew, and scientists, and there are several passageways that branch off from the ship's main body and end in shuttle docks or smaller domes that contain landscapes, such as oceans, deserts, or mountains; the Galaxy Rangers' Astro Megaship was secretly docked beneath one of these domes.
Terra Venture is a space colony holding a massive city, similar to Angel Grove, that was created to carry several hundred thousand people from all over the world across the galaxy to an unspecified "new world". The purpose of Terra Venture was to escape the constant monster attacks on Earth and find a new home for innocent civilians. Most of the inhabitants are actually from Angel Grove, the center of the alien attacks over the past several years. Its origins were not stated in the show.
Terra Venture's voyage got off to a bad start, becoming embroiled in a conflict between Scorpius and the Galaxy Rangers. This conflict draws in the Magna Defender, who nearly destroys Terra Venture while trying to annihilate Scorpius. In addition, one of the high councilors of the station is kidnapped.
Terra Venture is briefly pulled into The Lost Galaxy, where it is attacked by Captain Mutiny and his band of space pirates. While there, in Hexuba's Graveyard, the crew discovers that Terra Venture's fuel reserves are tainted and they will soon lose engine power at which point all systems will shut down and Terra Venture will freeze. They are left with only a day or two before this happens. However, with the help of the Power Rangers and the new Magna Defender, Mike Corbett, it escapes. Unfortunately, not long after that, Scorpius' daughter Trakeena returned and launched a full assault on the station forcing the colonists to evacuate to nearby Mirinoi. Trakeena later attempts to crash the remnants of Terra Venture onto the planet as means of destroying its survivors, but she was eventually destroyed by Leo Corbett (using the Battlizer) and the central dome was stopped by the Galaxy Megazord. The people of Terra Venture then apparently settle on Mirinoi, having found a suitable "new world".
How or when travel and communication became available to the settlers and natives of Mirinoi after the Terra Venture's destruction is largely unexplored after Lost Galaxy ends. When the Galaxy Rangers returned to Earth to stop Trakeena and Triskull (and later when Leo joins the Red Rangers on the moon to stop the resurrection of Serpentera), the use of the portal that lead Maya to and from Mirinoi and the Jet Jammers were used as their primary form of transit.
Some form of shuttle or other means of traveling through the portal may have become available between Mirinoi and Earth during events of Lightspeed Rescue and Time Force in the years 2000 and 2001, respectively. Bulk, who accompanied Terra Venture alongside Professor Phenomenus, appears on Earth during the Wild Force episode "Forever Red", running a tropical themed juice bar, named "Bulkmeiers", with Skull. Alpha 6, who was last seen on Mirinoi, was returned to Angel Grove at an unknown point during the Operation Overdrive episode "Once a Ranger", packed in a crate and deactivated.
