SCART, (Star Cataloging And ReTrieval System), was a highly complex operating system mandated for use on all Human starships starting around 2100 C.E. to around 113800 C.E. The first version was cleared for use on all spacegoing vessels around 2101 C.E. It had received continual updates ever since until around 120000 C.E., and the current version required a massive computer to run it. The only surviving module from SCART in the year 200000 C.E. is it's user interface; the rest of the system has been replaced with various new technologies.
It was mainly used to help starship captains in their mission of exploration. The system had been designed for ease of use, and it can instantly display information on any selected system, and whether or not it has any planets. It can also identify life on said planets, although to decipher exactly what kind of life requires an actual survey.
Scan times had been extremely sluggish for the first few versions; until around the year 2250, one simple scan of the Sol System took anywhere from a few hours to a couple days, as the fairly weak computer hardware at the time could not cope with the massive amount of data coming in. This was reduced to tens of minutes in the years following, to about the year 4000, when it was reduced further to at most 5 minutes. It was completely rewritten after the invention of the Wormhole Drive in 9952 C.E., and now boasts instantaneous retrieval speeds thanks to a new A.I. that was added. It can make sense of the complex data coming through the sensors at an alarming rate.

The massive computer system required to run the operating system required at least 20,000 512-core processors running at 450 Exahertz, 7,000 liquid-cooled RAMDAC units containing 1,512 Petabytes of memory, the ability to display the operating system on thousands of ship monitors at once, and at least 2 decks of ship space on a science vessel. The 32 independent drives used to run the USER program, from which SCART derives all of its data, contain 512 petabytes of memory, with 1,500 RAMDAC cooling modules and 2 256-core processors running at 200 exahertz. Most modern (a.k.a, circa 9900 C.E.) ships were actually designed around the actual computer installed in a custom-built bay. It had no cooling system; instead, one side is contoured according to the ship being built around it, and exposed to the coldness of space. This offers sufficient cooling. One could see this computer on a science vessel as a bright red band wrapping around the front of the ship. This computer was also responsible for opening wormholes for the drive, and the immense power required to do so means that SCART went offline for a few minutes.
The heart of the system was the Star Browser, which is still used in the current year 200000 C.E. It is capable of listing up to 10,000 stars, with information availiable on each one. It took just a few seconds to populate the listing, and it works in conjunction with the Wormhole Drive by locking onto the target star. The computer's power demands were raised 10-fold during scanning, and the system automatically re-assigned power from other ship systems temporarily.
The last version of SCART was 1943.4 (v418 since the rewrite). It took an estimated 10 years to write the initial version, and the last version consisted of up to 35 billion lines of code, roughly half of that for the A.I. called SCP, affectionately called "Skeep". "She" is as close to a living being as you could get with computer technology of the time.
The only surviving modules from the old SCART system are the Star Browser and USER program., as well as the main user interface. It has been largely replaced by various systems that are vastly more efficient than the old system was.
