https://en.wikipedia.org/wiki/Apollo_Guidance_Computerhttps://en.wikipedia.org/wiki/Saturn_La ... l_ComputerThe Apollo Guidance Computer (AGC) was a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft.[3]
The AGC has a 16-bit word length, with 15 data bits and one parity bit.The Saturn Launch Vehicle Digital Computer (LVDC) was a computer that provided the autopilot for the Saturn V rocket from launch to Earth orbit insertion.
The LVDC was capable of executing 12190 instructions per second. For comparison, a 2012-era microprocessor can execute 4 instructions per cycle at 3 GHz, achieving 12 billion instructions per second, one million times faster.
Its master clock ran at 2.048 MHz, but operations were performed bit-serially, with 4 cycles required to process each bit, 14 bits per phase, and 3 phases per instruction, for a basic time of 168 cycles = 82 μs for a simple add. (A few instructions, such as multiply or divide, took a few times this value.)
Memory was in the form of 13-bit syllables, each with a 14th parity bit.[1] Instructions were one syllable in size, while data words were two syllables (26 bits). Main memory was random access magnetic core, in the form of 4,096-word memory modules. Up to 8 modules provided a maximum of 32,768 words of memory. Ultrasonic delay lines provided temporary storage.
For reliability, the LVDC used triple-redundant logic and a voting system. The computer included three identical logic systems. Each logic system was split into a seven-stage pipeline. At each stage in the pipeline, a voting system would take a majority vote on the results, with the most popular result being passed on to the next stage in all pipelines. This meant that, for each of the seven stages, one module in any one of the three pipelines could fail, and the LVDC would still produce the correct results. The result was an estimated reliability of 99.6% over 250 hours of operation, which was far more than the few hours required for an Apollo mission.
With four memory modules, giving a total capacity of 16,384 words, the computer weighed 72.5 lb (32.9 kg), was 29.5×12.5×10.5 inches in size (74×32×27 cm) and consumed 137 watts.
The IBM7030 Stretch, one of the first supercomputers, had computing power of roughly 100x anything else available. It was the fastest available computer until about 1964. It spawned the IBM System/360 that NASA purchased 5 of to run the Apollo program simulations and design calculations. Those System/360's were doing ground computing while the rocket was en route to the moon. They'd compute course corrections, burn lengths, etc.
That System/360 computer was capable of ~1 MFLOPS (1 million floating point operations per second)
An outdated iPhone 7 puts out around 300 GFLOPS (1 billion floating point operations per second)
Your phone is 300,000x more powerful than a mainframe computer system that took up a room.

the computer was a hardware computer with hilariously small computing power. Woven by hand.

They were integral because they were the simple calculators of the time. But the rockets were designed and flown by utilizing (at the time) massive amounts of computer power.

HOPEFULLY it will be to also celebrate accepting my new job...if the offer comes in.
Im on fucking pins. I bet my BP is over 140. I really need it to come in so i can put in my two weeks and peace out for vacation and never come back....new employer knew this too.

No...the moon base was more about preparing for a base on Mars. Using it as a testing ground of sorts.dubshow wrote: ↑Wed Jul 17, 2019 10:51 amthey talk about moon base at all for staging?Detroit wrote: ↑Wed Jul 17, 2019 9:33 am
Interview went into that...he said they're starting from scratch right now and recognized that 5 years for development to launch is aggressive.
But apparently the recent budget allocated to NASA is enough to get it done. He went into how they're working faster than they ever have, leveraging cutting edge tech and modeling to make it happen.
