The Pioneer crafts still worked with the sequencer-and-computer architecture, meaning they could only run the commands on board set by NASA Ames on the ground. The ability to reprogram the craft helped it move beyond the outer solar system and toward measuring particles in interstellar space. It enables the agency to re-program the craft as needed using primitive assembly languages like Cobol, Fortran, and Algol. They also have some of the first CPUs ever used by NASA, enabling the agency to move beyond the sequencer. These probes, launched in 1977, visited the outer solar system and are now on the fastest trajectories of any craft as they head into interstellar space. And it let NASA enter a golden era of exploration, one that continues today with the Voyager probes. It allowed something that computers had struggled with before: handling multiple commands at once. In 1971, the central processing unit became commercially available. The 1970s brought immense change to NASA. While making flight adjustments, for instance, it would check the spacecraft's orientation and position against what the sequencers were programmed to do, "and if they don't match abort, the burn and try again." Still, it only had about 100 commands it could understand based on a 512-word "vocabulary."Ĭhris Jones, a chief engineer at NASA's Jet Propulsion Laboratory, told Motherboard it was similar to a diagnostic check. For instance, Mariner 8 could store data and run slightly more complex commands by kicking on sequencers in a cycle. In this particular build, given there's no room for going tubes down where the radiator currently sits, mounting it in the top as an exhaust would be much better for its long-term health, if that works with the RAM.Later Mariner missions, which explored Mercury, Venus and Mars, were equipped with a very, very limited computer that was paired with the sequencer clocks. Mounting the radiator tubes up can be detrimental to its longevity there's a factory-default measure of air inside AIOs, and in your current configuration this will sit right where the liquid circulates to & from the radiator which isn't great: Not at all intending this as a "haha you're wrong n000000b," I only have your best interest in mind. Who knows how many people read this comment and assumed I was correct without watching the video I was (inaccurately) referring to, who now think mounting a radiator tubes up with the pump further down will kill your AIO. Also general apology for spreading misinformation. I've PM'd OP, explaining this & apologizing for misinforming them with something potentially stressful. I love you all! And I hope everyone here will finish their dream builds too!Įdit: correction after re-watching the video linked here: mounting the radiator tubes up with the pump at a lower elevation than the top of the radiator is fine with regards to AIO health, but it may cause the gurgling/bubbling that's a semi-common issue people complain about regarding AIOs, as air pooling at the top of the radiator gets sucked down through the pump & spat back out again up by the rad. I didn't think this would get as big as it did. The position that the AIO is currently in is the only way it can fit unfortunately :( On the bright side my CPU temps are goodĮDIT #2: Thank you for all the awards and kind words. I tried top mounted and it couldn't clear my RAM and I tried with the tubes down with a front mount and it couldn't clear my GPU. It was an exhausting project, but it's finally complete.ĮDIT: Guys I couldn't fit the AIO in any other configuration. I figured this was a way to combine my hobby of PCs building and aviation. I've always been a fan of space exploration and aviation.
