The Space-Time Distortion Sensor was co-developed by Aperture Science laboratories in conjunction with scientists working in the Dark Space Shipyards. The main goal of the project was to bypass "mundane" means of scanning an area by simply sensing the raw distortions in the space-time continuum made by bodies of mass. The project began development in 2560, not reaching fruition or really gaining any ground until years later in 2580, when another Halo was located. The technological data from the Forerunners caused the project to leap forward in bounds. By 2585 a working prototype was created and tested aboard the UNSC al-Qiyāmah, with limited success. It had a significantly shorter range due to the power required to operate the device. It was also fairly large and delicate, leading to frequ
