Shulou(Shulou.com)11/24 Report--

CTOnews.com, August 19 (Xinhua)-- the nearly $10 billion James Webb Space Telescope (JWST) has finally launched. According to newly revealed documents, the telescope runs JavaScript scripts most commonly used by front-end web developers.

According to the manuscript (PDF) of JWST's Integrated Scientific instrument Module (ISIM), ISIM's software is controlled by the script processor Task (SP), which runs a script written in JavaScript upon receipt of a command.

Script execution is executed by the JavaScript engine, which runs as a separate task, which allows ten concurrent JavaScript to run independently of each other.

According to the documentation, the James Webb Space Telescope has a stack of pre-written scripts for specific tasks that scientists on the ground can tell the telescope to run directly.

These JavaScript will be interpreted by a program called a script processor, which will then access other applications and systems it needs according to the script's requirements.

More surprisingly, The Verge reported that the JavaScript script for the Weber Telescope is Nombas ScriptEase 5.00e, one of the early versions of JavaScript, which was last updated in 2003.

NASA documents show that this approach gives "operators more visibility, control and flexibility over the operation of the telescope" and allows them to easily change the script "when they understand the consequences and subtleties of operating the instrument." in this respect, JavaScript is indeed more convenient. However, the script processor itself is written in C++.

CTOnews.com previously reported that the Weber space telescope has a 68GB SSD (solid state drive) built into it, 3% of which is not available because it is reserved for the above engineering and telemetry data storage.
