00:00Do you know how Voyager can write top-notch software with the lowest requirements and

00:04update the software in space for more than 50 years?

00:08In 2010, a piece of Voyager hardware could not function properly because a zero in the

00:13program became a one.

00:15If the program cannot be updated, many scientific experiments of Voyager will be scrapped.

00:22Let's understand step by step.

00:24For the hardware of Voyager's computer, memory is a big highlight because it is only

00:2970 kdb and all programs run here.

00:32This requires engineers to have efficient code-writing abilities, which not only contain

00:37basic machine code but also use some pseudo-code shortcut instructions.

00:43When the interpreter encounters a predetermined code, it will start the corresponding pseudo-code

00:48instruction to execute the command, thereby saving a lot of memory space.

00:53The software of Voyager is written in assembly language with Fortran characteristics because

00:58assembly language can directly map machine instructions, which is closer to the binary

01:03nature of machine language, zero and one.

01:07After the new code is written, it will be compiled into machine code.

01:11The message is sent to Voyager via the Deep Space Network.

01:15The entire sending process takes about a day.

01:18The computer on Voyager uses an interrupt driver and the new update package will carry

01:23an interrupt signal.

01:25When Voyager receives the message, the computer will stop the command being executed, execute

01:30the new update package command, and then correct the error in the original program to perform

01:35the software update.

01:37Finally, the program checks whether it is normal.

01:40If it is correct, the computer starts the program and returns to normal operation.

01:45I have to say, these engineers are all geniuses.
