Orbital Solar Energy Transfer Satellite

An Orbital Solar Energy Transfer Satellite (also known as an Orbital Mirror and Solar Mirror was used to focus warmth and sunlight from Coruscant's tiny sun on the planet's extreme northern and southern latitudes, warming the environment by a few degrees to make more of the land area on the ecumenopolis habitable. These would be used by the Galactic Republic, Galactic Empire and the [New Republic]].

During the Imperial era, these mirrors were operated by low-ranking Imperial Navy staff. Many considered "riding the mirrors" the worst possible job in the Imperial Navy. However, a few, most notably Virar Needa considered it a noble duty, spinning a cocoon of self-delusion that allowed him to perform his menial assignment with the utmost efficiency and enthusiasm. For example, while most OSETS officers would shirk the task of maintaining traffic observation logs, Needa made it his hobby. These logs later proved valuable in the search for Lai Nootka.

Later, in 5 ABY, when the New Republic attempted to retake Coruscant from the Imperials, Rogue Squadron hijacked the computer center on Coruscant which controlled the OSETS satellites and took control of OSETS 2711 which was being staffed by Needa. The Rebels realigned the satellite to heat up a large water reservoir, creating a terrible thunderstorm that brought down the planet's shields. Moments later, the New Republic Defense Fleet jumped into the Coruscant system and commenced their liberation of the throne world.

Rogue Squadron also used OSETS 2711 to burn a hole into one of the Imperial Golan III platforms, an event which helped reduce casualties on both sides. OSETS 2711 survived the battle, but the fate of Needa and his crew after the New Republic's conquest of Coruscant is still unknown.

The New Republic would presumably continue using OSETSs. In 23 ABY, Jedi trainees Jaina, Jacen Solo, Tenel Ka and Lowbacca used several solar mirrors to burn out the hidden space station Shadow Academy's cloaking systems, exposing it to the New Republic fleet. However, the station powered its hyperdrive and escaped into hyperspace.

During the Yuuzhan Vong conquest of Coruscant, the OSETs were presumably destroyed by the extragalactic invaders.
